Abrasion I hope you don't mind me starting with your comments from the other post. doing so to make a point. Your post said,
"Based off the reports I've been reading and from my own experience this season, it seems like the feds were right to lower the quota and increase size limits.
I think anyone that has been fluking this season would find it difficult to disagree...."
Would ask anyone who cares to give a reasonable explanation of the following facts based on NMFS's own data and relate it to Abrasion's comments.
I've posted many times before Spawning Stock Biomass (SSB) hit an all time low over the last 33 year history in 1989 when it was reported at ~7,000 metric tons. By 2002 it surged to ~50,000 metric tons, the high over that same period of time. That's over a 600% increase! An increase I want everyone to understand was accompanied with annual catch amounts that averaged 58% of SSB. Let me repeat that, over a 13-year period where the summer flounder SSB increased 600%, annual catch averaged 58% of SSB. Currently, based on NMFS reported statistics, we're running closer to 15%. If catch as NMFS would want us to believe is the problem and catch as a percentage of SSB has been cut by ~75% and in the absolute, then why does SSB remain in a free fall decline?
During the same 1989 through 2002 period when SSB exploded to ~50,000 metric tons, possession limits and size limits were 8 fish and 14" respectively from 1989 to 1996. 1997 marked the beginning of a series of continuous size limit increases coupled with possession limits reductions resulting in an initially gradual and currently much more pronounced decline in the fishery.
Correlate all this to Rutger "Length and Sex" study as well as recruitment statistics which have been absolutely crushed since size limit increases have been implemented and give me one reasonable explanation of how quota cuts and continued size limit increases are favorable to the fishery. In 1989 when SSB hit it's low of ~7,000 metric tons, the next five-years catch averaged ~11,000 metric tons and SSB more than doubled to ~15,000 metric tons over that five-year period. Today's catch quota is ~5,000 metric tons, SSB was reported to be 34,240 metric tons at the end of 2015 (last year reported) and still SSB continues at a rapid decline.
I just don't see how anyone can support continued regulatory changes mandating continued and unabated harvest of larger fluke when the statistics CLEARLY show the negative effects those policy decisions had and continue to have on the fishery. I welcome any other plausible explanations which would rationalize these trends and or justify the path NMFS has us on other than the fact their continued focus on increasing size limits to manage catch quotas is crippling the fishery.
And just so everyone has all the facts before sharing your theories, recruitment strength in 1989 was ~2,900 recruits (new fish age zero) to metric ton of SSB. In '15 that number dropped to 644 as part of a parallel and continuous decline every year size limit increase were adopted....every year. That's an ~78% decline in recruitment strength yet we continue the almost exclusive harvest of female fluke!
