NOAA will shortly propose a renewed set of listings of salmon populations under ESA. Since 1991, the federal government has listed 26 species of salmon and steelhead in the Northwest and California for protection under the ESA. In a lawsuit that followed these listings, a federal judge set aside the listing of Oregon Coast Coho salmon because NOAA failed to include closely-related hatchery fish in the listing decision. Since the same flaw was present in almost all of the other listing decisions, NOAA voluntarily agreed to reconsider all of our earlier listing decisions and to adjust our policy for considering hatchery fish in making those decisions - and NOAA will be asking the public to comment on both. NOAA’s decisions are driven by the science, which suggests benefits, risks, and uncertainties regarding salmon hatcheries. Simply put, some well-managed conservation hatcheries are fostering recovery of species, some hatcheries are having little or no effect, and some hatcheries potentially hinder recovery.
After re-evaluating the listing of 26 species of salmon and steelhead, and considering the science on hatcheries, we have preliminarily determined to propose relisting at least 25 of the 26 species, with evaluation of the remaining species still underway. A final proposal will be completed in the next two weeks and the new hatchery policy will be only one factor for the evaluation still under way.
That is certainly a much more reassuring stance from NOAA-F. It's great to hear that the new policy will likely not change the status of 25 of the 26 listed stocks this time around. However, it does not completely guarantee adequate protections for these threatened wild stocks in the future.
I now see that what Todd posted a few days ago was right on (What's new!?).... the key language being thrown around with some element of ambiguity is the concept of "divergence" of hatchery stock from wild stock. If the two are deemed "closely related" then they will be counted as one.
The key definition we must all keep our antennas up for is what level of genetic similarity NOAA is looking for. That might mean the progeny of only system-specific native wild broodstock. That could be tightened further to mean only one generation removed from wild broodstock.
As Todd said, the narrower the definition, then the better the situation. The broader the definition, the thinner the ice upon which NOAA-F is treading.
If this is the scheme they plan to use for counting these hatchery-produced fish, then
wild broodstock programs that operate with the intent of "rebuilding" depressed populations of native fish should NOT be fin-clipping the smolts they release. The returning adults should be able to escape the fishery and contribute to seeding the river gravel alongside the naturally produced fish. Eggs mined from wild stock should not be used to fuel production of fish that will be harvestable upon their return (until of course wild populations have recovered to the point that harvesting them is appropriate).
I must emphasize that any hatchery program operating under such guidelines is at best an experiment. There are as yet
ZERO published studies that support the concept that taking a pair of wild adults from the river and artificially raising their young in a hatchery can outperform simply just leaving that same pair of fish to do it on their own in the wild.
Perhaps hatchery reforms that include raising the juveniles in natural ponds where the fish must actively forage for sustenance and seek cover from natural predators (instead of being passively fed in protected concrete raceways) might actually improve the productivity of the hatchery
as measured by the number of returning adults rather than just the number of smolts released.
We shall see.
