A couple of quick comments. I am not trying to take a side in any personal arguments. My comments on CNR were based on reports in the scientific literature. In addition Russian scientists are looking at the effects on reproductive success of salmon with seal bites, another kind of CNR. UW scientists are studying sockeye in bristol Bay drainages that have net marks, dropouts from the gill net fishery, and comparing them to unmarked fish in the same spawning areas. All fishes share a basic endocrine system so studies on one species can be inferred to apply to other species. Stress on broodstock is a big concern in aquaculture operations but with sufficient broodstock it is compensated. With healthy fish populations CNR is not an immediate concern.
You drive home the nail with that hammer blow! My wife was involved with several different ESA species studies, and she said the recovery efforts around the spotted owl and murrellet are childs play compared to the work required for fish. In the work she did it required a team of around 5 biologists to do a comprehensive study of timber sales and their impacts over the course of a year. For steelhead she said her head would just spin. Rather than just having to do old growth studies for habitat, you have all of the following
- Watershed
- Logging/timber sales
- Road construction
- Sport fishing impacts if any related to ocean bycatch
- Commercial fishing by catch
- Predation by other endangered or protected species
- Urban growth issues
- Dams
Considering the number of players it's no wonder things don't get done....
