SINK-AND-FLOAT TYPE WIRE NET CAGE FOR FISH-AND-SHELLFISH CULTURE AND CULTURE OF FISH-AND-SHELLFISH

摘要

PROBLEM TO BE SOLVED: To provide a wire net cage holding a shelter, afforded with a corrosionproofing means and mounted with a reinforcing frame, and improved in operability as well as culturing performance through sinking and floating by the aid of artificial seabed. SOLUTION: This culture system is made up of a cubic wire net cage 1 with a bait feed port 5 composed of wire nets 1a, 1b, 1c respectively corresponding to the plural sides, bottom and face and designed to sink in and float from the sea, a reinforcing frame 3 mounted around the cage 1, a corrosionproofing means 6 applied to the cage 1, and a shelter 7 having plural attachment plates 7a erected at intervals and held in the cage 1; wherein, the corrosionproofing means 6 is constituted of a corrosionproofing cathode such as of metallic aluminum attached to the wire net cage 1 which, in turn, has such a construction to be disassembled that the plural side wire nets 1a each fitted with reinforcing members 3a, 3b, bottom wire net 1b and face wire net 1c are mutually connected and assembled into a cubic form and the reinforcing members are mutually connected to form the reinforceing frame 3 around the cage.
