A fishery that catches and kills sea lions is being threatened with extinction in New South Wales and Tasmania.
Key points:A study by a marine biologist has found that a number of the largest marine species are facing extinction in Western Australia, with large fish populations at riskThe study says there are signs that the world is catching up to the success of the Atlantic Salmon fisheryA report by the University of Tasmania has warned that large-scale fisheries like the Atlantic salmon fishery in Western Australian are in danger of being completely destroyed.
Researchers from the University’s Fisheries and Aquaculture Research Centre have released a report that found the world has been catching up with the success in Atlantic Salmon fishing.
Key findings:The report said that more than 100 species of marine animals, including sea lions, sea turtles, whales, dolphins, turtles and sharks, are facing a decline in the number of individuals around them in the western Australian and Tasmanian waters.
The researchers said there was evidence that the commercial Atlantic Salmon fisheries are in the process of being destroyed.
“This is the first time we’ve been able to document the impact of the loss of Atlantic Salmon in the Western Australian and Tasmania waters,” Professor Michael McLeod said.
“We have a very good understanding of how the Atlantic Fisheries Management Authority and the Tasmanian Government are managing Atlantic Salmon.”
There are signs the industry is catching on, particularly with the closure of a major catch site in Hobart.
“The research found there was a dramatic decline in Atlantic salmon numbers in the waters of Western Australia and Tasmania over the past year.”
The number of Atlantic salmon in Tasmanian and Western Australian waters has dropped by over 40 per cent in the past 12 months, and we are seeing a dramatic decrease in the numbers of the other large species, such as sea turtles and dolphins,” Professor McLeod explained.”
These results are also a direct result of the closure and removal of a large catch site, with the Atlantic fisheries management authority removing the Atlantic Fish and Fish Products (AFP) operation from the Hobart Bay, and the closure, in July 2016, of the Hobarts Biodiversity Marine Reserve.
“The study also found there were signs that large marine animals were becoming more vulnerable to extinction.
Professor McLeod says the research highlighted the need for urgent action to protect the large and important species in these waters.”
It’s important to recognise that Atlantic Salmon are a critically important species that contributes about 20 per cent of all the fish caught in Australia,” Professor Mcklemont said.”[But] we’ve seen an alarming decline in their numbers in Western and Central Australia, and our findings are also consistent with evidence of a decline of many other species in the region.
