I live in a mountainous area (over 2000 feet and 20 miles inland) of a Caribbean island. The local kids are sometimes hunting crabs in the muddy areas where springs give rise to small creeks. I built a house and one of my foundation drains is not quite level and it has standing water for a day or two after it rains. Thus it soon became inhabited by at least one large red crab. If I put in a shallow pond or maybe a whole raft of horizontal PVC pipes, would I have a crab farm here? The articles/websites I have found describe aquaculture in mangrove lagoons, but I am talking about a very different habitat I think. Certainly it is not brackish. Has anyone encountered a crab farm and what sort of detritus would one feed to crabs - I am thinking they might like the wastewater from upstream tilapia farming perhaps?
