Nonetheless, as I indicated above, the competition hypothesis has two components, one of which is competition among juveniles in the marine environment, particularly estuaries (mortality remains high at this life stage, once juveniles reach a certain size mortality falls dramatically). So, if competition among hatchery and wild juveniles is a significant contributor to the decline in wild adults returning to their natal waters, then reducing hatchery releases does not require other nations to cooperate, just requires Alaska hatcheries to reduce production.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9188370370448778552.post-51417909308060786942012-09-28T07:55:43.017-08:002012-09-28T07:55:43.017-08:00Hatchery production can be limited how?

After careful calculations, they needed to catch 80k more. When it opened, they struggled mightily to find some fish. It stayed open forever, finally closing, but only after the department opened high abundance areas. The lack of fish, the king salmon abundance index, the departments moronic management style, which flies in the face of the abundance based management approach, all collided for a perfect storm of lunacy. Trollers get cut back all the time. Puhleese. Summer trolling will close, except in a few small areas, where it already did close for wild coho consevation, on September 30th. It will open for winter kings on October 11. It will remain open until April 15th. The day winter kings closes, special hatchery access areas will open throughout southeast. These will remain open until the July 1 opener, the beginning of the summer season, which will have a short opener to allow Patty Skannes to count fish. Then it all starts up again.

A very good argument for the decline can be as simple as over harvest by the users. They run and mingle with other targeted salmon and other targeted species and are caught at the same time and in many cases are not reported and probably always under reported. For a Cook inlet set net fisher or a trawler, or an Area M or BB or western chum fisher to report a Chinook caught is like driving another small nail into their own coffin. And take a look at some of the walls in the lodges and Kenai guide's homes and see the thousands of chinooks held up for pictures. Someone told me that Bob Penny's mansion sports over a thousand pictures of one or more big wigs holding large dead salmon. No, i really believe that the Chinooks are about to go away as far as any big numbers are concerned and will be a fish that we will about from the 'good old days' Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9188370370448778552.post-81410496932422198872012-09-25T13:18:21.901-08:002012-09-25T13:18:21.901-08:00Anonymous 9/21 @ 5:59PM "carrying capacity is...Anonymous 9/21 @ 5:59PM "carrying capacity is limited by primary productivity."<br /><br />Agreed and the rest is just detail I suppose. But the devil is in the details.<br /><br />"Of course, it is also possible that the prey base is not THE limiting factor affecting wild Chinook production (or at least returns),"<br /><br />Bingo.<br /><br />There is currently no good way to know where we are with respect to marine carrying capacity for king salmon. It is a very complex question that will probably never be fully understood. It is extremely unlikely that multiple stocks would be subject to the same limiting factors and we don't even know the home ranges of any of the stocks. Top predators like king salmon are so heavily fished that it is hard to believe that any of them could be able to escape capture in numbers high enough to bump up against food limitations but anything is possible I guess. Empirical data is a lot better than speculation but unfortunately, we don't have much of that.<br /><br />"for you to suggest that carrying-capacity is an unlikely cause is just silly and disingenuous."<br /><br />It would be but then I'm not the one suggesting that. What I have said is that no one has the data to do much more than speculate about carrying capacity for king salmon. Maybe it is and maybe it isn't. Hey if you have references to scientific reports that do more than rehash the correlations between hatchery fry releases and wild king salmon stocks please cite them.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9188370370448778552.post-87367661834635841952012-09-24T06:53:09.407-08:002012-09-24T06:53:09.407-08:00Post the credentials of ADF&G's "scie...Post the credentials of ADF&G's "science team" and how they worked their way up the ladder as state employees.

Winter kings, hatchery access openings in the spring, have by-catch and a unknown mortality of undersized king salmon.
