Editorial: Exploitation Of Fish Stocks - No Such Thing

No fish species in New Zealand or around the world is in danger of extinction caused by commercial fishing, a fisheries scientist said earlier this week,

Ray Hilborn, professor of aquatic and fishery science at the University of Washington, began a three-year study in 2006 which showed that for those countries where there was available data on fish stocks, "the abundance of commercially harvested stocks are either stable or increasing, not declining".

"In the areas that are traditionally the most overfished in the world – Europe, Eastern US, Eastern Canada, the site of the cod collapses and all that, we see stability, not decline."

He also said that the perception that the world's overall tuna stocks were disappearing was wrong.

Contradicting this, researchers from the University of British Columbia have said that predatory fish, such as cod, tuna, and groupers have declined by two-thirds over the past 100 years, while small forage fish such as sardine, anchovy and capelin have more than doubled over the same period.

The teams findings, led by Professor Villy Christensen, of the simultaneous decline of predatory fish and increase of forage fish provides the strongest evidence to date that humans are “fishing down the food web” and impacting ecosystems globally.
