In Blackwater there is a spot by the butcher which has fish swimming most, not all, of the time, and if you are lucky you can get a few lake sturgeon. its nice bc as soon as you get one you walk 20 feet behind you and sell it to the butcher. I also like north of St Denis there is a small peninsula where you can catch river fish, sometime sturgeon, and exotic birds like heron and spoonbill while also getting gators some boar, maybe a deer and turkeys. North of St Denis has a lot of birds, fish and gators. You can make $100 in about 20 or so minutes with some skill and luck
