An AOS survey completed in winter 2019 found that there were 42,600 tonnes of adult fish spawning on two hills in the eastern zone. Immature, non-spawning and southern fish were not surveyed and are additional to this.

In July 1862, Victoria’s out-going Inspector of Fisheries and Oyster Beds, James Putwain, wrote a report of his observations of the colony’s commercial fisheries to deputy premier Charles Duffy. Irish-born Duffy was the Commissioner for Public Works, President of the Board of Land and Works, and Commissioner for Crown Lands and Survey, later to become Premier of Victoria.
Reckoned to be of public interest, Putwain’s report was published in the Lands Circular of the day.
Apart from its general historical interest in describing the fishes, fishing gear and boats of the time, this report remarks on the vulnerability of commercial fishermen to market wholesalers. It also comments on the particular role of Chinese, both as fishermen and as a discrete section of the fish-buying community at the time.
FISHERIES OF VICTORIA
In connection with the 53rd section of the Land Act, which authorises the issue of licences to occupy Crown lands for the purposes of Fishermen’s residences and drying grounds, Mr Duffy obtained a report from the gentleman who recently held the office of Inspector of Fisheries and Oyster Beds; and as the report is highly valuable and interesting, he has directed it to be published for general information.
St Leonards, 30th July 1862
SIR – I am in receipt of your letter dated the 14th of July, and beg to state, in consequence of my removal from Williamstown, it has only just come to hand, requesting me to furnish to the Honorable the President of the Board of Land and Works a statement of the kinds and quantities of fish taken in Hobson’s Bay, Western Port, and other parts of the colony, together with the number of vessels and men employed; also to distinguish the operations of the Chinamen, should there be anything peculiar in their habits.
I beg to submit the following statement:-
The kinds of fish taken in Hobson’s and Port Phillip bays.
1. Schnapper are taken in large quantities by hooking, from two to four miles inside the Heads, principally in deep water, commencing in September; they have been occasionally taken during the winter months in Bass’s Straits. The smaller schnapper are taken more or less all round the Bay with seines. I do not think that these fish come within Port Phillip Heads for the purpose of spawning, the roe always being found in them during the season. They are taken in large quantities; some weeks there are thirty to forty tons, which, when not sent to the market, are disposed of to the Chinamen for the purpose of drying for their countrymen.
2. Salmon* are also taken about the beginning of September, and during the summer months, in large quantities, by the seine, all round Port Phillip Bay, principally near the Heads; they are generally met with in large shoals; I have seen them in Bass’s Straits, during the winter, in shoals more than a quarter of a mile in length. I believe they cast their spawn in shallow water; they are frequently taken more than a ton at a time. *The fish must not be mistaken for the salmon of Europe.
3. Pike make their appearance in October, and are taken all round Hobson’s and Port Phillip Bays, by seine, set nets, and hooking.
4. Bream and silver fish are taken by the seine and hooking during the summer months, and are also taken in shallow water in the winter. I believe the bream cast their spawn in brackish water, and the silver fish in shallow or grassy beds.
5. Mullet, whiting, and flat-heads are taken more or less all the year round. The mullet is a particularly shy fish, and is generally taken in thick shallow water; a fine thread net is required for taking them.
The whiting (the principal marketable fish) is taken occasionally in the seine, but generally by hooking, in the south-west of Port Phillip Bay. Of the flat-heads there are two kinds, one of which is taken all round Port Phillip Bay, in sandy or muddy bottoms; the other is found about the rocks, and is much darker in colour. Flat-heads are taken in large quantities by seine and hooking; they are also found in waters 20 to 40 fathoms deep outside the Heads. Their supply is from ten to twelve hundredweight per day.
6. Guard fish are taken by the seine; they require a bunt or the centre of the net made expressly for them during the winter; they are found in grassy beds or shallow water in large quantities, particularly on the western shore. The supply is from three to four tons per week.
7. Sole and flounders are ground fish and are exceedingly scarce; the flounders are taken near shore by the seine in muddy bottoms; the sole are seldom taken, as they inhabit the edges of banks in deeper water, and they require a particular trawl which is rarely used in this colony; they are a very rich and delicate fish, resembling the home brill both in shape and flavor, and I believe they are plentiful if properly fished for.
Having mentioned the principal marketable fish, I beg to state that I have seen mackerel taken in Port Phillip Bay; they resemble the home fish in shape and color, but are not so large; they are plentiful in Bass’s Straits; there is also the king fish; I have seen them in large quantities in the Rip between the two heads of Point Nepean and Point Lonsdale; they are sometimes, but very rarely, taken in the bays; they are a good eating fish and resemble the home salmon. I think they could be taken in any quantity in Bass’s Straits with such lines as are used in the north of England in the cod fisheries.
I believe there are many valuable species of fish in Bass’s Straits (having found them on several occasions dead, and washed ashore on the back beach by Western Port Bay) which have hitherto been quite unknown; and I consider it would be a great acquisition to the fisheries if the banks or trail they inhabit could be discovered.
The description of fish that are taken at Western Port, Port Albert and Corner Inlet, are about the same.
These are generally small and open, from thirteen to twenty-two feet in length; there are from one hundred to one hundred and seventy in constant use in Port Phillip Bay, including the Chinamen’s; there are from two to four in each boat. I find there are men of all nations engaged in the fisheries, more foreigners than Englishmen. As regards the habits of the Chinamen, I find nothing peculiar in their manner or mode of fishing; they are very zealous in their work; they were in the habit of using very small nets, and saving small fish which they dried for the use of their countrymen. I always found them very obedient to instructions given them regarding the removal of the small nets. I have discovered Europeans and others procuring and making use of the nets the Chinamen had cast aside as illegal. There are only a few stationed at Western Port or Port Albert, as they migrate from bay to bay to suit the seasons. The market is supplied by four decked boats running between Queenscliff, Swan Bay, and the Sandridge jetty, and also by an overland route from Western Port to Melbourne, via Frankston, Mordialloc, and Ricket’s Point.
I beg to state that there is a great diminution in several species of fish within the last six years, viz whiting, mullet, guard fish, and bream, which is attributable to the use of the small nets. I find the Select Committee on Fisheries, in their supposed Amendment Bill, have recommended (and I believe it has since passed the House) the use of one-inch mesh, through the complaints of ruthless destroyers who pretended they were unable to obtain a living with the one-inch and quarter mesh. I do most firmly believe and am able to produce the opinions of some of the oldest fishermen in the colony, that if the one-inch mesh be allowed to be used, it will be the means of entirely exterminating several species of fish that have not yet fallen victims to the small-meshed nets.
The following is a statement I have obtained from one of the oldest fishermen in this neighbourhood, showing the quantity and the prices obtained for the different kinds of fish, and also the necessity of a fish market: –
He remarks that these fish were all in the best possible condition and first class quality, and I can say with certainty, that this person is one of the most industrious fishermen I know.
By the above you will notice the great disparity in the prices obtained by the producer, when compared with the price the consumer has to pay. This is caused by the monopoly at present enjoyed by the men who buy from the fishermen, who in turn sell to the retailers, and receive an undue portion of the profits. They will continue to do so as long as there is no established fish market, where fishermen can send their fish to properly qualified salesmen; by this means the fishermen would get a better price for their fish, and the public would pay less than they do at present. Were a market to be established, I believe it would give encouragement to many who would turn their attention to fishing, but the low prices that they must submit to (or lose the fish) hinders many from embarking in what would be a very good living.
I have the honor to be, Sir,
Your most obedient servant

The peak industry body for commercial fishers in Victoria is Seafood Industry Victoria (SIV). SIV is funded by a small compulsory fee on all Victorian fishing licences.
The Victorian Government recently wrote to Victorian fishers asking if they wanted to continue paying this fee. Victoria has shut down net fishing in Port Phillip Bay, has reduced the days that remaining operators can work (so that they are not visible to recreational anglers) and has scheduled the closure of the Gippsland Lakes Fishery (to promote recreational angling). Therefore, many in the industry believed that the Victorian Government’s goal was to remove any remaining barrier to shutting down more fisheries.
However, the Victorian industry has sent a clear message to Government and come out in support of SIV with 77% of Victorian licence holders that responded being strongly in favour of retaining SIV as their representative peak body.
In an emailed statement to SETFIA, SIV’s EO Johnathon Davey says that SIV with the support of industry has the mandate as the representative of the Victorian industry, will develop labelling standards for Victorian Seafood and will try to grow the desire of the Victorian consumers to understand the story behind their seafood.’
Four years ago, AFMA installed cameras on gillnet vessels targeting sharks in the south-east fishery to monitor dolphin and sea-lion interactions.
However, a consequence of doing this was that human observers were removed from these vessels. These observers collected data on interactions with dolphins and seals but also collected lengths and vertebrae, which are used to age sharks. These “biological” samples are used to understand the growth and the recruitment of young sharks both of which are critical in the assessment of the gummy and school shark stock.
SSIA* has now been engaged by AFMA to collect these biological samples. Gillnet and hook vessels take a sample of sharks when directed by randomly tagging some of the sharks caught on a trip. Each tag has a unique number and when entered into the database by SIDaC samplers each shark can be traced back to the depth, fishing method, vessel and area in which it was caught.
Vessels then deliver these tagged sharks to port samplers who measure the length of the sharks and take a vertebra from about half the sharks. The vertebrae are cleaned, frozen and then encased in resin before being sawed in half. A fish ageing specialist can then read growth rings in the vertebrae much like growth rings in a tree.
A very similar program to sample pink ling and blue eye trevalla has being simultaneously rolled out for the auto line sector of the fishery.
SSIA have engaged Ross Bromley, an ex-AFMA manager, to co-ordinate this work. The project would like to thank port samplers Jeff North, Atlantis Fisheries Consulting Group , Ross Bennett, AFMA staff at Lakes Entrance, Nick and Chris Pitliangas, Kyri Toumazos, Toni Clarke, the Lakes Entrance Fisherman’s Co Operative, Heath Rogers and Bob Shaw from Mure’s Fishing. Thanks too to the crews supplying samples: the skippers and crew of the sample vessels Cape Everard, Morrie D, Christine Claire, Candice K, Jean Bryant, Diana, Lutarna, Peter Crombie.
If you are a gillnet or hook vessel operating in the fishery and would like to be involved in the project or would like to become involved in the sampling of gummy or school sharks, or ling and blue eye trevalla please email Ross here.

Not content with their exclusive fishing access to every Victorian estuary, recreational fishers are now pushing for the closure of commercial fishing in the Gippsland Lakes.
From the 1960s through the 1980s, Victoria’s annual 800 tonne Gippsland Lakes commercial fishery produced 80% of Australia’s black bream landings, averaging about 250 tonnes.
Today, the Gippsland Lakes commercial fishery is under extreme pressure from recreational fishers and related business interests. Flushed with the success of the 2014 campaign to end commercial net fishing in Port Phillip Bay, these interest groups are pressing the major political parties to bring an end to commercial fishing in the Lakes.
Success for this campaign would mean the end of another 10 perfectly sustainable family fishing businesses and the end of Victorian consumers’ access to black bream.
So, in the lead-up to Victoria’s November election, what positions will the major parties adopt regarding the future of fishing in the Gippsland Lakes?
Victoria’s 23-year record of fisheries and stock assessments have consistently shown the sustainability of the black bream and overall Gippsland Lakes fisheries. Together with environmental assessments of the lakes system, these studies have tracked changes to fish habitats and fish stocks which have been matched with fisheries management changes.
Commercial fishermen have been proactive in initiating some important changes: in 1996 they observed the apparent total loss of juvenile bream throughout the lakes. When surveys drew similar observations, the Government introduced emergency controls including tight monthly commercial catch limits and reduced recreational catch limits. Many years earlier, the closure of commercial fishing on weekends and public holidays had a marked effect in easing competition with anglers.
The 1996 event brought about lasting changes: an increase in the legal minimum length for bream and the continuation of reductions in the numbers of commercial fishing licences. Since 1995 alone, the number has been reduced from 21 to 10, mainly as a result of voluntary licence buy-outs.
As the numbers of licences have decreased, the level of commercial fish production has fallen accordingly. In 1995/96 the total catch was 721 tonnes, including 130 tonnes of bream: in 2016/17 the total catch was 316 tonnes including 42 tonnes of bream.
The most recent estimate of the recreational catch from the lakes was 203 tonnes of bream in 2000/01.
Two comparative studies of the economic values of commercial and recreational fishing in Victoria’s bays and inlets showed no grounds for re-allocating fish resources between the sectors.
In 2017, the Victorian Fisheries Authority conducted detailed assessments of the State’s key marine stocks. To lend additional rigour to the process, interstate fisheries managers and scientists participated in the assessments. Drawing on detailed long-term commercial and recreational fisheries data sets, they found that the combined pressures from fisheries for black bream in the Gippsland Lakes are sustainable, as were the recreational-only fisheries in other eastern and western Victorian inlets.
Their conclusion was that “Appropriate management is in place.”
In contrast, none of the current anti-netting campaigns offer any evidence that commercial fishing is unsustainable or incompatible with angling. Referring to the state of fish stocks and to angling success, statements such as “the decline is attributed to commercial fishing” offer no supporting evidence of declines from fishing or other causes.
Current political pressure
Since 1994, VRFish and local anglers have participated in at least seven Gippsland Lakes black bream and fishery assessments, all of which found fishing to be sustainable. When presented with the evidence they agreed with the conclusions and the management implications.
Today, against this solid background of evidence-based policy and fisheries management come spirited appeals to end commercial fishing in the lakes. Recreational fishing peak body, VRFish’s, key push to ‘save our Gippsland Lakes’ is a compulsory buy-out of all 10 licences as part of their ‘fish recovery plan.’ A change.org petition asserts that ‘it’s time to end commercial netting of fish in the Gippsland Lakes’ to ensure ‘the sustainability of the Gippsland Region.’ The Futurefish Foundation web page simply urges “Ban netting in the Gippsland Lakes.”
VFA creel surveys show that angling success in the lakes is comparable to success in other East Gippsland inlets where anglers face no ‘competition’ from commercial fishing. The evidence simply confirms what we know about recreational fishing everywhere: the majority of anglers catch very few fish. Removing commercial fishing pressure – spread across 20 fish species – would not alter that reality.
The economic importance of recreational fishing to the Gippsland Region, including tourism, is widely acknowledged. While the anti-netting campaigns claim that these benefits are threatened by commercial fishing, the VFA’s 2017 assessment shows that this is plainly untrue. In fact, the full social and economic value from fisheries in the Gippsland Lakes can only continue if the viable commercial fishery is retained. This has to be good news for government, seafood consumers and the wider Victorian community.
Victorian seafood consumers’ keenness for bream can be seen in the prices they’re prepared to pay: about $30/kg which is more than they’ll pay for snapper.
Anyone who has read reports of fishing offences in Victoria might recall the prevalence of illegal gill-netting in rivers and streams around the bays, inlets and coastline. Whether in the Werribee, Paterson or Tambo rivers, the main target for these activities is black bream. This is a reflection of high prices and an unmet market demand for the species.
Speaking of markets, there’s more at stake here than 300 tonnes of fresh fish annually. The Lakes Entrance Fishermens Co-op is a major source of Victorian and inter-state fish supplies. The Co-op operates on very thin financial margins and closure of the lakes fishery would seriously threaten its continued viability. As a popular direct outlet for fresh fish, the Co-op shop depends on the lakes fishery. Without that fishery the shop would be likely to close as trawl-caught fish can be unavailable for weeks at a time during unfavourable seasonal conditions offshore.
In 2014, the major political parties bowed to pressure from recreational fishing interests and committed to banning the commercial net fishery in Port Phillip Bay. They did so without any consideration of the proven sustainability of that fishery.
Faced with similar pressures in 2018, what will the major parties do? Will they seek balanced evidence-based policy advice from the VFA? If so, what advice will they receive and how will they balance this against pressure from recreational fishing interests?
The outcomes will be revealed in the next couple of months.

The harvest strategy in the South-East aims to maintain tiger flathead stocks at a pre-determined % of the pre-fishing, or virgin, biomass. This is called the target reference point. The flathead stock has been above this target for many years so fishermen have enjoyed quotas (total allowable catches or TACs) designed to slightly reduce flathead stocks down to that reference point. However, the last flathead assessment showed that flathead is almost at that reference point so the quota has declined.
Less quota means less revenue so fishermen within the Association began to think about how to increase the per kg value of flathead. One way is to catch larger flathead because larger flathead have a higher per kg price. The market pays more for larger flathead because they are easier to fillet and they returns a higher yield of fillets as a % of whole weight.
Using larger mesh in the last section of the net called the codend increases the average size of flathead caught.
However, using larger mesh and not catching medium sized fish means less catch which means that fishermen must shoot their net more often, spend more time at sea and potentially increase their operating costs. There are also costs to change to new fishing gear.
The debate was not an easy one but SETFIA members have resolved through a formal vote to increase Danish seine mesh size. Two non-SETFIA member seiners were contacted and both supported the idea.
SETFIA has written to AFMA stating that they would like AFMA to increase the minimum mesh size in Danish Seine codends to 75mm by 1 May 2019 (the start of the new fishing season).
SETFIA has contacted fishing gear suppliers and advised them of the likely change so that they can adjust their supply.
Sustainable fishing practices protect our future.
From July 1 2018, new Australian Marine Park management plans will come into effect, creating new rules for where fishing can occur in 44 marine parks around the country. Australian Marine Parks are located in Commonwealth waters, 3 to 200 nautical miles from the coastline, beyond state water boundaries.
Commercial fishing can occur in yellow and blue zones within these new Networks, in accordance with a class approval issued under each management plan. Class approvals set out the areas where commercial fishing can occur, the fishing methods that can be used, and the conditions that need to be followed while operating or transiting.
Parks Australia aims to contact all operators that fish in or near these new Australian Marine Parks, to inform them of the new requirements in advance of 1 July. This will include the final class approvals and factsheets for the Coral Sea Marine Park, Temperate East Network, South-west Network, North-west Network and North Network of Marine Parks. The factsheets will outline what you need to be aware of in order to comply and will include information on how to access electronic maps/files of all marine park boundaries. All documents will soon be available on the Parks Australia website: https://parksaustralia.gov.au/marine/

The NSW and Australian Governments have been working on merging the NSW managed Southern Fish Trawl and the Commonwealth managed South East Trawl fisheries. The NSW trawl fishery operates inside 3 nautical miles and the Commonwealth trawl fishery between 3 and 200 nautical miles.
The push for the merger has come because the two fisheries often target the same species with the same trawl method and operate side by side but do so under different rules and restrictions. The 2016 Productivity Commission report investigated management inefficiencies between Commonwealth and State fisheries and recommended that these fisheries merge.
An agreement between NSW and the Commonwealth sets down how the two fisheries operate and share the resource.
NSW operators have limits on “Commonwealth quota” stocks like tiger flathead. This frustrates NSW operators because they are often forced to discard commercially valuable fish that have little chance of survival.
Commonwealth operators are frustrated because NSW catches are debited to Commonwealth quotas. This ensures that the sustainable limit, set by the Commonwealth, is not exceeded but means that Commonwealth operators are the last in the line and only receive what NSW don’t catch (noting NSW vessels can only catch limited volumes). Commonwealth fisheries are also frustrated that the NSW fishery does not contribute to the cost of assessing stocks.
Often fishers hold both NSW and Commonwealth endorsements but cannot operate inside and outside the 3-mile line on a single trip. This too is inefficient.
All this because a line was placed at 3 nautical miles in NSW based how far a cannon ball could be fired in the 17th century.
The truth is that both sectors have an equally strong right to operate and there must be a better way to organise a fishery.
The NSW and Australian Governments formed the Southern Fish Trawl Working Group made up of fishers, associations and managers from both fisheries, they have agreed how the NSW Southern Fish Trawl could become part of the Commonwealth South East Trawl. NSW released a consultation document that captured these proposals. The proposal is that rather than debit NSW catches to Commonwealth quotas, that NSW operators should become Commonwealth operators working on a special permit allowing them inside “the line” (3 miles) and be issued around 246 tonnes of Commonwealth quota. A separate NSW allocation panel would divide up this quota across the 23 NSW operators.
Under this system there is no change to the sustainable catch and no quota is taken from existing owners to give to new NSW entrants to the Commonwealth system – the catch is already coming off Commonwealth quotas.
The Committee also made recommendations that NSW vessels entering the Commonwealth fishery should operate seabird bafflers, VMS (satellite monitoring) and be subject to normal conditions such as ongoing efforts to reduce discards and by-catch.
SETFIA supports the transition under these terms and believes it offers the many benefits:
* fish trawling in south-east Australia will be managed by a single jurisdiction and many fish species will have a cap on how much can be caught each year;
*better data collection and improved understanding of stock status;
*one jurisdiction removes duplication and administrative burden;
*where the required concessions are held, fishers will be able to complete a single trip inside and outside NSW waters;
*security of access for NSW fishers will be increased
*no more trip limits and less discarded fish from NSW vessels.
The Association is frustrated at some recreational fishing groups who have led with headlines like, “the trawlers are coming”. This is clearly not the case, there has been a trawl fishery inside NSW waters for more than 100 years. What is being proposed is just a better outcome for the fishing industry and the Australian community.
Latest financial and economic survey results from operators in the Commonwealth Trawl Sector (South East Trawl) shows that the profitability of vessels operating in the fishery improved in 2014-15.
Generating a gross value of fishery production of almost $43 million in 2015-16, the South East Trawl is the major supplier of locally caught finfish to Melbourne and Sydney fish markets.
The survey undertaken by the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) for the 2013-14 and 2014-15 financial year show that profit at full equity (a profit indicator that assumes all assets are fully owned by operators) increased for the average boat in the CTS from $131,000 in 2013–14 to nearly $154,000 in 2014–15. The improvement was primarily due to lower average costs on items like fuel.
The rise in average vessel performance is also reflected in an improvement in net economic returns (NERs) from the fishery in 2014-15. ‘NER’ measures how well the fishery has performed as a whole and accounts for all revenue and costs of the fishery including all management costs, owner labour (even where there is no cash transaction) and capital employed in the fishery. ABARES estimates that net economic returns continued to improve for the fishery in 2015-16 and 2016-17 reaching $4.2 million by 2016-17. Three years of consecutive growth in returns is great news for trawl operators, particularly as it comes following a three year period of decline.
ABARES is currently undertaking the next survey of Commonwealth Trawl Operators of the fishery covering the 2015-16 and 2016-17 financial years.
The latest survey results can be found at:
Buried deep in the icy mountains of a remote island in Norway, is a seed storage facility that currently houses almost 1 million plant seeds from almost every country in the world. Located 100 meters inside a mountain on the island of Spitsbergen, in the remote Arctic Svalbard archipelago, 1,300 kilometres from the North Pole its purpose is to be the ultimate insurance policy for the world’s food supply, offering options for future generations to overcome the challenges of climate change and population growth. It will secure, for centuries, millions of seeds representing every important food crop variety available in the world today.
The location for the seed vault was chosen for various reasons; the area is geologically stable, has low humidity and is well above sea level so is unlikely to flood even if sea levels rise significantly. A temperature of -18ºC is required for optimal storage of the seeds and the permafrost that the vault is built into provides a cost effective and fail safe method of keeping the seeds frozen naturally. Although remote, Svalbard is still accessible on a commercial flight.
The vault has the maximum capacity to store 4.5 million varieties of crops which is equivalent to 2.5 billion seeds. It is currently the most diverse collection of food crop seeds in the world ranging from unique varieties of major African and Asian food staples such as maize, rice, wheat, cowpea, and sorghum to European and South American varieties of eggplant, lettuce, barley, and potato.
The global seed vault in Svalbard was established as the final backup to the 1,700 plus gene banks that exist around the world that hold crop seeds for safe keeping.
But in a cruel twist of fate it seems that the seed vault my not be the all-withstanding fortress it was meant to be. The climate is changing and the northern polar region is warming twice as fast as the global average – and the permafrost that is currently preserving the seeds is melting! Last year’s record soaring temperatures in the Arctic caused melting and heavy rain that that flooded the start of the tunnel that leads to the vault. If Arctic winter temperatures continue to rise, the so called ‘Doomsday Vault’ itself may be doomed.
There is a growing acceptance that the world’s food production will need to grow by 50-100% by 2050. Seafood is the largest contributor to the planet’s protein. Good fisheries management is the ‘vault’ that must protect our fish stocks.
