Behind every successful seabird-breeding season are thousands of tiny fish. Anchovies, herring, smelt, saury鈥攖hese are just a few examples of the 鈥溾 seabirds depend on to survive and rear healthy chicks. These nutritious schools are a crucial link in the food chain, supporting not just birds but also a wide range of larger fish and marine mammals.
Now issued by the National Oceanic and Atmospheric Administration (NOAA) has recognized the massive ecological impact of these small ocean dwellers, and is protecting them from large-scale fishing off the West Coast. The statute makes dozens of forage fish species鈥攖he vast majority of the region鈥檚 populations鈥攐ff limits to commercial fishermen, who are increasingly targeting them to produce mass quantities of fishmeal for agriculture and aquaculture. Under the ruling, fishermen wanting to target any of the protected forage fish species will now be denied approval until they can prove that their impact on the species鈥攁nd the broader ecosystem鈥攊s negligible.
The ban, which affects federal waters beyond three miles off the coast, is a result of nearly four years of advocacy work by several conservation groups, including the 约炮视频, Pew Trusts, and Oceana鈥攑lus the support of multiple commercial and recreational fishing groups, which recognize the importance that forage fish play in boosting other seafood stocks. It went into effect at the beginning of April, and is being implemented by NOAA鈥檚 National Marine Fisheries Council (NMFC). The restrictions protect off of California, Oregon, and Washington. This 280,000-square-mile area is particularly biodiverse and rich in nutrients, thanks in part to the California Current, which runs south from Canada to Baja and causes major upwellings in the Pacific.
More Fish in the Sea (for Birds, Anyway)
The NOAA decision follows on the heels of a 2006 in federal waters off the West Coast. The guidelines set a precedent that essentially 鈥渇orged the path鈥 for the forage-fish ban, says Anna Weinstein, 约炮视频 California鈥檚 seabird and marine program director.
The ensuing benefits are huge for forage fish, which are struggling under the of climate change, ocean acidification, pollution, and overfishing. One major concern is that the exact factors driving sudden population declines鈥攍ike the infamous Pacific sardine collapse 鈥攁re often poorly understood. Overfishing, for one, can suddenly tip a population over the edge, with severe ramifications for the species that feed on it.
鈥淭oo often we鈥檙e responding to species where there鈥檚 a risk of them going extinct,鈥 says , Oceana鈥檚 Pacific campaign manager and senior scientist. That鈥檚 what makes this ruling unusual: It proactively covers many forage species at once, and uses an ecosystem-wide conservation approach.
For 约炮视频, the ban also represents a monumental victory for seabirds. Over the course of the long decision-making process, 约炮视频 California, the 约炮视频 Society of Portland, and 约炮视频 Washington contributed research on the importance of forage fish for birds, and mobilized public support for the regulation. 鈥淭o me, it showed the power of our network,鈥 says Gail Gatton, executive director of 约炮视频 Washington. 鈥淚nstead of being a bunch of individuals working on it, we were a connected group.鈥 NOAA reports that it received in support of the ban.
The ruling protects some of the most important prey options for seabirds: round herring, thread herring, Pacific saury, silversides, smelts, Pacific sand lances, and pelagic squid species. Before, these species weren鈥檛 even part of any conservation plan. 鈥淭hese seven groups had fallen under the radar,鈥 says Joe Liebezeit, avian conservation manager with the 约炮视频 Society of Portland. But changing that amounts to a massive ecological win. 鈥淐ombined with the previous measures to protect krill, this new ruling safeguards roughly 70 percent of all forage fish鈥攂y weight鈥攊n the California Current,鈥 says Oceana鈥檚 Enticknap.
Certain climate-threatened species will benefit directly from the new regulations. The Black-footed Albatross, for example, preys on the now-protected neon flying squid, and the Rhinoceros Auklet eats sand lances, which are also covered by the fishing ban. Weinstein reckons that in addition to an estimated 30 local bird species, another 60 to 80 migratory species that flock to the West Coast on a seasonal basis will benefit.
A Boon for Seabirds in the Long Run
Protecting forage fish is like buying life insurance for at-risk seabirds. Species such as Sooty Shearwaters are already threatened by climate change and habitat pressures, which are forcing them to abandon their nests; rampant fishing only . If there鈥檚 a low anchovy stock one year, for instance, birds need to be able to fall back on another species, like saury. 鈥淵ou want to preserve diversity and abundance of prey鈥攃alled the 鈥榩reyscape,鈥 鈥 Weinstein explains.
To determine which fish species are most important for seabirds, 约炮视频 California and the 约炮视频 Society of Portland worked with the Farallon Institute, a nonprofit organization that does scientific research on marine ecosystems, to use its to rank individual forage fish species in terms of their dietary importance to seabirds. That science was then used to convince the NMFC to include those fish in its final list of protected species.
The evidence was a strong selling point for the ban. 鈥淭he potential benefits to birds were a significant consideration in the background analyses for the action,鈥 says Yvonne deReynier, a senior resource management specialist at NOAA Fisheries.
Liebezeit thinks the next step is to extend the lockdown on forage fishing to the three-mile-wide zone along the California, Oregon, and Washington coastlines. 鈥淭his would benefit near-shore feeding species, such as the Marbled Murrelet,鈥 he says.
In the meantime, the landmark ruling is being celebrated as a rare case of success in the world of marine conservation. 鈥淚鈥檓 really excited about this,鈥 Weinstein says, 鈥渘ot just the actual impact on the water, but that a real, practical example has been set for how to get it done. Signed, sealed, delivered鈥攖hat鈥檚 like gold.鈥
