"Crab Fishing"
Most of the crabs I've caught have been opportunistic grabs. I have a few small rocks at the top of the tank that have few hiding places and are easy to pull. If I see a crab on one, I can pull it from the water and dislodge the crab with little trouble. The hard ones to catch are in the 10 to 20lb. base rocks. For those, time, patience and the test tube in the picture have provided some (minor) success. The test tube is glass; about a half inch wide by 5 inches deep (shorter would be better but I don't have one). There is a piece of nonwaxed dental floss tied to the front end of it. A piece of shrimp is placed in the bottom and it is gently maneuvered into place with the opening very close to where the crab hangs out. The crab eventually moves into the test tube and I pull the tube vertical and out of the tank. I've caught two crabs this way and each crab took several days of getting brave enough to climb in. I found that , contrary to other reports, the crabs are quite capable of moving along the glass, so leaving the tube in the tank unattended has been fruitless. I had to be present to pull the tube out while the crab was deep enough in it. I hope that helps, but it can be tedious waiting for the crabs to take the plunge, so to speak.
