METHOD FOR CULTUERING CATADROMOUS FISH(ANGUILLA MARMORATA) BY USING RECIRCULATING AQUACULTUER SYSTEM AND SEAWATER ACCLIMATION

摘要

The present invention relates to the methods of cultivation and relates more specifically to a kind of method and be used to cultivate drop freshwater fish (Anguilla marmorata) by a circulatory system and determine the seawater acclimation of phase, it can give fabulous structure, taste by using specific drug ecology and drop freshwater fish biological properties, color, etc.. According to an aspect of the present invention, if it is the method for cultivating drop freshwater fish includes: a pocket-handkerchief transfer step (100), one pocket-handkerchief, it cultivates step (200), and one adapt to step (300) and method characteristic and be to include adapting to, cultivation step, wherein water scalds to be generated by it allows drop freshwater fish to be moved to the boiling hot opposite of water using venture-attachment water motor in an adaptation water tank, drops freshwater fish by acclimation 30-40 days without supply. According to the present invention, in the seawater acclimation for determining phase, freshwater fish drops, including Anguilla marmorata, be suitble to customer preference due to taste with color to be to natural one as, can be prepared by holding the adaptation of drop freshwater fish without supply. As in the present invention using the circulatory system for agricultural, the material dissolved, such as excrement, residual feed, ammonia, nitrite, etc., the invention problem in fishing ground is removed efficiently, to improve farming efficiency, the antibiotic abuse of excessive supply and fishing ground is reduced to cut operating cost and maximize customer preference.
