METHOD OF AQUAFARMING FISHES OR SHELLFISHES

摘要

It is intended to provide a method of aquafarming fishes or shellfishes whereby the growth of the fishes or shellfishes can be promoted and an aquafarm can be effectively utilized while neither requiring a complicated apparatus, exerting undesirably effects on the natural environment nor worsening the bottom qualities or the water qualities. An aquafarming farm (80) has a preserve (50), which consists of a raft (51) putting on a certain sea area and a net (52) provided under the sea below it, and a controlling system (70) formed on a raft (71) located adjacent to the preserve (50). A large number of red sea breams (53) are fed within the net (52) in the preserve (50). A microbubble generator (1) is provided in the seawater in the preserve (50) and a large amount of capitellidae (55) are distributed at the bottom (54a) of the sea area in which the preserve (50) is formed. By supplying electricity and air from a power generating machine (72) and an air pump (73) on the raft (71) into the microbubble generator (1), seawater containing microbubbles (NB) is supplied into the seawater (W) in the preserve (50).
