Backyard Aquaponics
A place to discuss aquaponics

It is entirely possible I did not have the proper salinity, however most of the crabs died in combat in their own blue crab civil war rather than simply expire on their own.

If I try blue crab again, however I will make certain the salinity is correct first. My main issue then becomes "what sort of plant that's worth cultivating can put up with and/or thrive in that salinity?"

Shelgeyr, 0.3 ppt is low enough that (nearly) everything would be fine. I see strawberries recommended at no more than 1ppt, and they are about the most salt sensitive. I believe many members run 2-3ppt as normal, and just dont grow strawberries. I'd guess that the gradual change is important though.
