TL: SEALS (GP) SO: Greenpeace International DT: Unknown Keywords: oceans marine mammals greenpeace gp groups seals factsheets / The oceans used to abound with seals, sea lions and fur seals, a group collectively known as pinnipeds. They were abundant throughout the polar and sub-polar regions of the world, and were integral components of the dynamic equilibrium of species which constitutes a marine food web. Pinnipeds are mammals, evolved for an aquatic existence from land- dwelling ancestors of dogs, bears and otters; therein lie their greatest downfalls. As warm-blooded animals inhabiting a cold environment, they require dense, luxurious fur or blubber as insulation. Unfortunately, humans have long prized both the skins and oil which come from seals. While seals are highly specialized for life in water, they must return to either land or ice to give birth. The dense assemblages that they form at this time, combined with their clumsiness out of water, means that they fall easy prey to the clubs and guns of sealers. Today, the threats confronting pinnipeds are relentless and diverse. They are slaughtered commercially, drowned by the thousands in fishermen's nets, killed in the name of fisheries management, poisoned by chemicals, used as fish bait, and, in some cases, driven from their habitat. The most insidious menace of all results from human over-fishing, which may deprive them of the food they require to survive. Threats from the Fishing Industry The most widespread and dangerous threats to seals come from the fishing industry. Accusations against seals are usually one of three types. The first is that they eat too many fish, thereby contributing to the poor condition of fish stocks in many areas of the world and depriving fishermen of their livelihood. Seals should thus be killed to protect fishermen. This is a naive and simplistic argument, and ignores the extraordinary complexity of the marine environment. Not all fish fall prey to seals or die in fishing nets; the vast majority die from disease or are eaten by larger fish or other predators. Of the fish which seals do eat, many are from species which are of no commercial importance, or in areas in which no fisheries exist. It is also possible that certain fisheries benefit from the presence of seals, through the seals' consumption of certain fish species which are themselves major predators of other commercially valuable species. The assumption that fish and seals cannot coexist does not stand up to logic or historical fact. One need only recall that, until so many of the world's fish stocks were devastated by modern fishing methods a few scant decades ago, there were both many more seals and many more fish. No one was suggesting that seals should be killed to allow more fish to be caught by fishermen. Secondly, since seals are necessary for the completion of the life cycle of certain fish parasites, it is often suggested that fewer seals would mean fewer worms in the flesh of fish. However, the life histories of these parasites are very complex, involving many alternate hosts, and depending on many other factors. Killing seals will not solve this problem either. More efficient fish processing is the way to ensure a high quality fish product. Thirdly, seals have been known to damage the gear and catch of fishermen. The effects of this problem are usually quite localized, and the average losses to individual fishermen are rarely large. Better fishing methods and more appropriate gear will reduce this type of interaction much more efficiently than killing large numbers of seals. One or more of these arguments have been used by the fishing industry as justification for demands to kill seals. Culls or hunts have been demanded in South Africa, Greece, the United Kingdom, the United States, Canada, Scandinavia, Australia virtually everywhere seals exist. In none of these areas has it been shown that killing seals will result in any improvement in the size or quality of fishermen's catches. The Canadian government admitted as much in December 1987 when it announced that it could not justify a cull of grey seals. It is true that many of the world's fish stocks are in disastrous shape, and that the fishing industry has many problems, such as declining catches, variable quality product, and excess catching capacity. However, years of relentless over- fishing, the use of destructive and non-selective gear, the physical and chemical destruction of fish habitat and other wasteful practices are the real causes, not seals which are gamely attempting to recover from the earlier destruction of their populations. Rather than being the culprits in this situation, seals should more correctly be viewed as the unfortunate victims of our abuse of the marine environment. Every year, large numbers of seals are caught and drowned in fishing nets and discarded gear worldwide. In Norway, tens of thousands of harp seals have drowned in coastal gill nets in recent winters. Entanglement in discarded fishing gear may be contributing to the current decline in the population of northern fur seals in the Pacific. Even worse, the ability of modern fishing fleets to plunder fish stocks in a few years has caused problems for some seal species. In the Barents Sea, to the north of Norway, several fish stocks have been reduced to very low levels. As a result, harp seals from the area have been unable to find food and many are reported to be in poor condition; this could have drastic consequences for the population. Elephant seals have been declining in the southern Indian Ocean for several years, and scientists have suggested that overfishing may be responsible. Currently available scientific evidence makes it clear that seals are not the cause of the poor state of many of the world's fish stocks. They are threatened just as surely as the fish stocks themselves by the rapidly expanding capacity of the modern fishing industry. Such problems can only worsen, as fishing operations become more intense and competitive. Commercial Exploitation Virtually every species of pinniped has, at one time or another, been the object of an uncontrolled hunting frenzy. A tragic pattern has repeated itself around the globe. As lands inhabited by seals were discovered, sealers arrived to kill them for their skins and oil, and in a few short years the population would exist no more. The magnitude of this slaughter is staggering: it has been estimated that over 12 million fur seals alone have been slaughtered during the past 200 years. Many species were brought to the brink of extinction. One, the Caribbean monk seal, was pushed over the edge, and many others are still battling for survival. Some are losing. Today, harp and hooded seals in the North Atlantic are the victims of the world's largest seal hunts. Wherever they have been found, these species were hunted mercilessly, and over the centuries several tens of millions have been clubbed for their hides and oil. The result was that the populations of harps and hoods have all been severely reduced. Due to widespread concern for the health of these seal herds, in 1983 the European Community imposed a ban on the importation of skins of certain harp and hooded seals, which has since been made permanent. The loss of this market caused a temporary decline in the numbers of seals killed. However, hunts for harps and hoods have increased in the past few years, as sealers are searching out new markets. Chemical Pollution Despite the fact that seals frequently live in remote areas, far from industrialized areas, chemical pollutants have been found in species as diverse as walrus from northern Greenland and Weddell seals in the Antarctic. Since pinnipeds are long lived and at the top of the marine food web, chemicals accumulate in their tissues to levels that are far higher than in their environment. In several areas of the world, pollutants have been associated with health problems in seals. Female California sea lions which aborted their pups were found to have higher levels of PCB's and DDT than mothers producing normal pups. In areas of the Baltic and Wadden Seas in northern Europe, several species of seals have failed to recover after protection from hunting was granted in the 1960's. These seals have very high levels of PCB's and DDT, which have been shown to inhibit reproduction in harbour seals. What is Greenpeace doing? Greenpeace has been active for many years fighting these threats to the survival of seals, both locally and on an international level. Green peace is opposed to the culling of seals done in the name of protecting fish stocks. With the increasing severity of the threats posed by the fishing industry, efforts have been intensified against the demands for killing seals. Green peace has already helped to prevent culls in Canada, the United States, Britain and Australia. Greenpeace is opposed to the commercial hunting of seals. Since 1976, Greenpeace has been campaigning to protect seals from commercial hunting. Tactics as diverse as direct action, advertising and lobbying for protective legislation have been used in the battle to protect harps, hoods, fur seals and other species, from the North Pacific to northern Europe. Many successes have been achieved, such as a permanent ban on the importation of certain seal skins into the European Community, the termination of the large vessel seal hunt in Canada, and the ending of the commercial fur seal hunt in the United States. Greenpeace has major, effective campaigns against toxic pollution around the world. It is only by combatting the production, use and disposal of poisonous chemicals that the oceans will be made clean and safe for seals, as well as other marine animals such as whales, turtles and fish. What can you do? Write to the governments of Canada, Norway, Britain, Australia, the United States, South Africa, Greece, and any other country that allows the killing of seals in the name of protecting fish stocks. Tell them that seals are not destroying commercial fish stocks, that they are innocent victims of over-fishing and poor management. Write to the governments of countries such as Canada, Norway, the Soviet Union and South Africa which are still conducting commercial seal hunts. Tell them you want them to stop, that the world today will no longer support such old fashioned, irresponsible industries. Write to your government, and tell them to stop polluting the environment, for it all ends up in the oceans eventually.
