The commercial troll fleet has been high grading for ever! They are only allowed so many fish per week. So, all the small ones usually go back dead, and all the big ones get caught! Doesn't take a genius to figure out that if you eliminate all the big ones from the gene pool, you end up with little fish. When they cut into the Kings and see that they are White, or Marbled (yes, there are a lot of Marbled Kings) they get thrown overboard as well, dead, as they don't get nearly as much money for them as they do the Jumbo Reds! Also, the Gill Nets and Purse Seine nets strain out the big fish, contributing to the demise of the larger fish! Sad damn deal!
