This, however, wasn’t the only problem. The Hill, as fishermen call it, was a “tragedy of the commons,” says Peter Trott, fisheries program manager with the World Wildlife Foundation in Australia. “At least in the early years,” he goes on to explain.
The tragedy of the commons
Coined by biologist Garrett Hardin, the expression describes a situation in which individuals, acting independently and rationally, deplete a shared resource such as a village common or fishing area. each individual gains by herding an extra animal or taking an extra load of fish, though this individual action invites ruin of the resource for the whole community. Elinor Ostrom (-), winner of the Nobel Memorial Prize in economic sciences, claimed that such ruin is not inevitable, that people don’t always act for short-term profit and that locals often come up with solutions themselves. However, she noted, “If the community doesn’t have a good way of communicating with each other or the costs of self-organization are too high, then they won’t organize and there will be failures.”
The Hill falls within Australia’s Southern and Eastern Scalefish and Shark Fishery. When the roughy breeding ground was discovered, little was known about the fish and less about the biomass (number) available to be fished. Estimates varied from 100,000 to a million tons. In, the management quota of 12,000 tons was caught in three weeks and estimated at $23 million.
“Initial reports on the biomass amounted to [little more than]: ‘There is so much fish, you’ll never catch it.’ Unfortunately, that is an old adage that quickly proved to be false. It was an open fishery with good money to be made and very little control,” says Trott.
Inadequate surveillance systems tempted crews to file false reports about the size and location of their catch. By one assessment, the number landed in Hobart in was twice the official recorded catch.
The attitude then by the government was one of, ‘go for it, guys.’ Peter Trott “The attitude then by the government was one of, ‘Go for it, guys.’ Fishing was an industry to be developed and it wasn’t much about sustainability,” explains Trott.
Governments at the time provided policies to help exploit fisheries. These ranged from boat-building subsidies to exploratory fishing programs. While scientists urged caution, commenting that “very little catch is forgone by slow development of the fishery,” catch limits were often set without reference to scientific opinion. With research then only beginning, Trott says, “There was no real idea what damage was being done.”
It has since been revealed that the orange roughy has an extraordinary life span of up to 150 years. This, coupled with the fact that it is a slow-breeding species that begins reproducing at about 30 years of age, means the orange roughy is susceptible to overfishing.
Throughout the, changes were initiated, including limiting the total allowed catch and introducing licenses, but by then, says Trott, the damage had been done. In, the Hill was closed to fishing and the orange roughy was listed as a conservation-dependent species, the first rung on the Australian conservation listings.
COUNTING THE COST
Fritz Drenkhahn, also former head of the industry body the South East Trawl Fishing Industry Association, says at the peak there were 52 boats fishing the Hill. “Nothing can sustain that sort of pressure,” he acknowledges. But what fishermen didn’t like was the manner of the lockdown on their fishing.
“We knew when the catch rates went down that there was a problem, but you just can’t stop us dead. We told the government and scientists, ‘Work with us, because you need to keep the industry going, even at a reduced rate.’ Otherwise the infrastructure falls apart.”
In, a buyout of permits took half of the 118 boats of the south-east fleet off the water. It devastated small towns, whose economies depended on the sea. Drenkhahn’s hometown of Eden, a small fishing village of 3,000 people, located equidistant from Sydney and Melbourne, went from 15 boats down to five, and the infrastructure declined with it.
“They tried to curtail it with one huge swipe, but then everything falls apart. If they opened the Hill today, there would be few boats around to fish it and no process to handle it. Most of the boats left are going broke,” he argues. “And the Hill was never even close to being fished out according to assessments we pushed for.”
“Have you ever tried to count fish?” asks Rudy Kloser. “It is quite a task.” One of the scientists charged with monitoring stocks of orange roughy, Kloser says recent surveys have shown large schools of fish at the Hill. “I am talking up to one kilometer long and a 100 meters high, so there are a lot of fish there. But that doesn’t tell you how many fish used to be there,” he explains.
Debate today circles the existing spawning biomass. The latest accepted assessment shows stocks at the Hill are still considered low, at around 16% relative to unfished levels, and the Hill remains closed. Australian fisheries have a limit reference of 20%. If the estimated stock size drops below that, the fishery closes for rebuilding. If it rises substantially, it could re-open for fishing.
Have you ever tried to count fish? It is quite a task Rudy Kloser “There are indicators that show it is recovering, but we cannot be certain of the rate and the level,” says Kloser. “If it is opened up, what are the management risks in the longer term? The full effects of the overfishing are not likely to be felt until after, when most of the juvenile fish from those overfishing years reach maturity and return to breed.”
The tale of the orange roughy is a cautiously optimistic one. The species was heavily fished at a time when powerful trawlers were seeking an alternative to depleted inshore stocks, such as gemfish. Although regulation was initially unprepared and, at least in the fishing industry’s view, there was an overreaction, it seems the species is recovering and could provide a basis for a sustainable industry.
Elsewhere, the picture is not promising. Today, 414 species of fish are considered critically endangered, according to the “Red List” maintained by the International Union for Conservation of Nature. Another 486 fish species are endangered, 1,141 are vulnerable and 60 are extinct due to overfishing by the world’s 4.36 million fishing boats.
In its report on The State of the World Fisheries and Aquaculture, the UN Food and Agriculture Organization said a third of fish stocks are overexploited and 57% are fully exploited. The report notes that its analysis suggests “a global system that is overstressed, reducing in biodiversity and in imminent danger of collapse.”
