Jurien bay fish deaths under investigation
The first study, published in June 2014, linked the increase in 더킹카지노the percentage of the Asian carp death rate from 10% to 18%, with a peak in deaths among younger fishers. But researchers from the University of Stellenbosch in South Africa found that the number of mortality in white sharks in particular had also risen in response to the increased catches and caught in more efficient boats.
“Our data shows that Asian carp are the most aggressive fish in captivity and we are currently examining them in the larger and more selective populations of white sharks,” said Mr Steltenburgh in a news release.
“The most significant change has been in the Asian carp’s tendency to kill white sharks and these sharks are now being caught more efficiently. These results have implications for aquaculture, because the increased consumption of small fishes in fish farms and on small trawls may be driving the increased Asian carp mortality.”
Other Asian carp species have also been found to be expanding in size, with an increasing proportion of their adult body mass showing signs of a dramatic transformation from egg-laying fish. The size of the Asian carp population may be declining but the increase is a huge concern for aquaculture.
Fisheries Minister Ian Hunter has called for Australia to boost its fishery quota under the Species at Risk Act of 1996, as well as for the number of fishing licences to be renewed each year.
“At a time of enormous economic pressures to our fishing industry, the proposed reforms to the SARA would further strengthen and safeguard these industries for the long term,” he said.
But with recent warnings by the Minister for Water Resources, the Australian Marine Conservation Society, the Commonwealth Scientific and Industrial Research Organisation and other organisations 바카라that the fish’s fate may be imminent, the SRS are calling for a moratorium on their annual report in October.
“The government’s response to the global seafood crisis shows that it remains firmly behind industry on this important issue,” said Dr Steltenburgh.
“A moratorium on quota renewals will give us the best chance to find solutions before the end of the financial year.”
