Fish Stocks Are Declining Worldwide, And Climate Change Is On The Hook

December 14, 2015 — For anyone paying attention, it’s no secret there’s a lot of weird stuff going on in the oceans right now. We’ve got a monster El Nino looming in the Pacific. Ocean acidification is prompting hand wringing among oyster lovers. Migrating fish populations have caused tensions between countries over fishing rights. And fishermen say they’re seeing unusual patterns in fish stocks they haven’t seen before.

Researchers now have more grim news to add to the mix. An analysis published Monday in the Proceedings of the National Academy of Sciences finds that the ability of fish populations to reproduce and replenish themselves is declining across the globe.

“This, as far as we know, is the first global-scale study that documents the actual productivity of fish stocks is in decline,” says lead author Gregory L. Britten, a doctoral student at the University of California, Irvine.

Britten and some fellow researchers looked at data from a global database of 262 commercial fish stocks in dozens of large marine ecosystems across the globe. They say they’ve identified a pattern of decline in juvenile fish (young fish that have not yet reached reproductive age) that is closely tied to a decline in the amount of phytoplankton, or microalgae, in the water.

Gulf of Alaska Groundfish to Reopen After NMFS Allocates 1600 Additional Chinook Salmon as Bycatch

SEAFOODNEWS.COM [SeafoodNews] — August 10, 2015 — NMFS has given Gulf of Alaska groundfish trawlers in the non-rockfish program Sector an additional 1,600 Chinook salmon to their prohibited species catch (PSC) allowance in an emergency ruling.

The implementation of the emergency decision was done after the North Pacific Management Council (NPFMC) recommended an emergency rule in a 10-1 vote during its June meeting. On May 3, the Gulf of Alaska groundfish sector was forced to close after fishermen unexpectedly reached its annual 2,700 Chinook salmon allowance in the Western and Central Gulf of fishery.

According to NMFS the additional limit of 1,600 Chinook salmon PSC is likely to restore a substantial portion of the forgone groundfish harvest and associated revenue made unavailable by the closure. It will allow the sector to harvest its recent average amount of groundfish for the remainder of 2015, while keeping the total Chinook salmon PSC well below the annual threshold for all Gulf of Alaska trawl fisheries.

“NOAA Fisheries has determined that an emergency exists because the early closure of the Non-Rockfish Program CV Sector’s groundfish fisheries is causing significant economic detriment to harvesters, processors and the community of Kodiak,” NMFS said in a press release on Friday.

A previous PSC management action, Amendment 93 to the FM was approved in June 2011 to limit Chinook salmon PSC to 25,000 Chinook salmon in the Western and Central GOA pollock trawl fisheries.

Because the Western and Central GOA non-pollock trawl fisheries were without a Chinook salmon PSC limit prior to 2014, the Council recommended that Chinook salmon PSC limits be extended to these fisheries under Amendment 97 to the FMP.

Amendment 97 to the FMP limits Chinook salmon PSC to a total of 7,500 Chinook salmon for the Western and Central GOA non-pollock trawl fisheries – 2,700 for the Non-Rockfish Program CV Sector, 3,600 for the Catcher/processor Sector, and 1,200 for the Rockfish Program CV Sector.

New data has shown that previous estimates of PSC for this sector were not representative of recent PSC use.

The additional allocation of 1,600 Chinook salmon would be consistent with the overall goals of Chinook salmon PSC management in the GOA trawl fisheries and would not substantially increase Chinook salmon PSC use relative to established limits NMFS said.

Based on current and anticipated incidental catch of Chinook salmon in the GOA trawl fisheries, NMFS anticipates that total Chinook salmon PSC by GOA trawl vessels is unlikely to exceed 32,500 Chinook salmon, well below the annual threshold of 40,000.

This temporary rule will mitigate the costs of the closure to participants in the fishery while the Council develops an FMP amendment to permanently address this situation.

This emergency rule is effective upon publication in the Federal Register today and will last until December 31, 2015, or until the new PSC limit of 1,600 Chinook salmon is reached by the Non-Rockfish Program CV Sector.
