Australian fisheries management says there are regional differences and new data only applies to population in New Zealand
New Zealand’s fisheries management assessed populations in one of its orange roughy fisheries and found that the age of breeding was “unexpectedly high” with only 50% of stocks spawning by 55 years old.The concerns have been raised as the new environment minister, Tanya Plibersek, travelled to Lisbon for the UN oceans conference. Plibersek has said she wants Australia to take a global leadership role in ocean protection.
Meder said sustainable fisheries practices typically tried to ensure that fish populations had a chance to start replacing themselves before they were caught. Karli Thomas, a New Zealand-based ocean advocate with the Deep Sea Conservation Coalition, said deep-sea trawling put fish and other species, including deep-sea corals, at risk.“If you look at the state of the stocks and the concerning science that’s coming out of New Zealand, no country would let New Zealand trawlers into their country to be trawling for this species,” she said.
They said there had been comprehensive data collection for orange roughy stocks in Australian since the 1990s and over many years it had shown that most of the fish that were gathering to breed were between 20 and 40 years old.
