Rough justice for threatened deep sea perchORANGE roughy has become the first commercially-caught fish to be added to Australia's list of threatened species. Known as deep sea perch, giant spawning aggregations of the slow-growing, long-lived fish have been taken by trawl nets in southern Australian waters. Protection under the law was needed if the species was to have any chance of long-term survival, the federal Environment Minister, Ian Campbell, said yesterday. Senator Campbell said roughy would be listed as "conservation dependent", and managed under a program implemented by the Australian Fisheries Management Authority. <!--break--> The Humane Society International, which nominated the fish for protection, said it was disappointed that commercial catches of the fish would continue. "A total allowable catch of 400 tonnes and a by-catch quota of 150 tonnes has been set," said the society's campaigner, Gemma Hunneyball.
"The species is now at 7 per cent of its unfished biomass. AFMA's own guidelines for sustainability say that targeted fishing should stop below 20 per cent."

Under normal circumstances the boat will rock to and fro, and there is a finite risk that the boat could be overturned by a rogue wave. But now one of the passengers has decided to stand up and is deliberately rocking the boat ever more violently. Someone suggests that this is likely to increase the chances of the boat capsizing. Another passenger then proposes that with his knowledge of chaotic dynamics he can counterbalance the first passenger and indeed, counter the natural rocking caused by the waves. But to do so he needs a huge array of sensors and enormous computational reasources to be ready to react efficiently but still wouldn't be able to guarantee absolute stability, and indeed, since the system is untested it might make things worse. So is the answer to a known and increasing human influence on climate an ever more elaborate system to control the climate? Or should the person rocking the boat just sit down?" |
