Talked to some of my son's friends who mate on charter boats.. every fish, bass or blue, the customer wants, gets filletted on the boat on the ride back, they throw the racks in a fish box for the lobster guys for trap bait.. fillets goes home in ziplock bags..
walk any cape beach first light/false dawn.. lotsa racks in the wash... fillet and released..
.. no harm, no foul, the crabs, and birds have it all gone by 7AM
