Create a Fisheries Advisory Board with a super majority of eight commercial fishermen (selected from within their own ranks) and just three recreational fishermen (two marine, one freshwater, selected by government authorities). The board could reach a quorum without any recreational-fishery representation whatsoever.
Limit recreational anglers harvest no more than 30 pounds of fish per month. (This will eliminate valuable fishing tournaments, and could mean keeping a single tuna or dolphinfish would be breaking the law.)
Allow commercial fishermen to keep most of a catch when found in violation, the government confiscating only that portion of a catch deemed not in compliance.
Allow commercial fishermen to keep their vessels; no matter how serious an infraction, confiscated would be proscribed. The same sort of protection would not be extended to recreational anglers, whose vessels could be confiscated.
Allow fisheries-management measures not based in science, but requires scientific studies to classify any species as "vulnerable." (This could take years, during which time fishing could continue
Grant commercial fishermen a free pass by overlooking the first violation of any fishing regulation, however egregious;
Grant commercial fishermen another free pass for initial infringement of by-catch regulations;
Eliminate seasonal fisheries closures.
