Speaking of which: I live where the Merrimack River meets the ocean - which is where I used to fish when I first moved (here) for the first 5 years - catching stripers, channel cats, the occasional eel, and crabs (lol.) A Korean couple started fishing next to me, most nights, and they would not put ANYTHING back - literally. They kept ANYTHING and EVERYTHING that came up on their line - including undersize stripers, crabs, tiny 10 inch eels, tiny 8 inch catfish, and the occasional squid.
For the past 5 years, I have not had one tiny nibble at all.
