CRAB CULTURING APPARATUS AND USE THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide a crab culturing apparatus effectively preventing the decrease of survived number of crabs caused by cannibalization or death of crabs during the period from a young crab to a grown crab of a marketable size and provide a method for effectively culturing crabs by using the apparatus. PSOLUTION: The crab culturing apparatus is produced by assembling 3 tubular structures each having openings at both ends or thereabout and an inner diameter to allow the passage of a crab. The apparatus is placed in a water tank containing flowing water directing the opening of the structure toward the water flow. Preferably, two or more apparatuses are placed with spaces to allow the movement of the crabs around each apparatus. Tubular structures having various sizes are prepared beforehand and the structure is exchanged to a larger one according to the growth of the crabs. PCOPYRIGHT: (C)2003,JPO
