Industrialized ecological cultivation method of ribbonfish

Abstract

The invention provides an industrialized ecological cultivation method of ribbonfish. The industrialized ecological cultivation method of the ribbonfish comprises the steps of (1) preparing cultivation facilities, (2) carrying out ecological cultivation, and (3) harvesting adult ribbonfish, wherein the average weight of the ribbonfish can reach 110-130g / piece, the ribbonfish is cultured for 16 months, and then the adult ribbonfish is harvested. The industrialized ecological cultivation method of the ribbonfish has the advantages that a greenhouse pond with an area of 2800 square meters is adopted for industrialized ecological cultivation of the ribbonfish, all indexes of the ribbonfish are controlled manually during cultivation, the water environment for the industrialized ecological cultivation is controlled manually, influence of the environment on the cultivation is reduced by means of circulation of materials based on the ecological balance rule and the energy flowing principle, and then a dynamic ribbonfish cultivation environment is created; the color of the body of the ribbonfish is bluish yellow which is close to the color of the body of wild ribbonfish, the ribbonfish cultivation cycle is shortened by more than one year, the protein content of the cultivated ribbonfish can reach more than 60%, the fat content of the cultivated ribbonfish can reach more than 29%, and the cultivated ribbonfish is rich in unsaturated fattyacid; the probability of occurrence of parasites during ribbonfish ecological cultivation is greatly reduced, and the survival rate of the cultivation is improved by 20%.

Description

technical field [0001] The invention relates to an industrialized ecological culturing method of saury, belonging to the technical field of aquaculture. Background technique [0002] As human activities have caused great damage to the living environment of saury, the total resources of saury have been severely reduced, the size has become smaller, and the germplasm has been degraded. The completion of large-scale dams has changed the original reproductive migration route of saury, and the pollution and destruction of the ecological environment have threatened the survival of saury. Therefore, the overall number of saury has been greatly reduced compared with before. With a breakthrough in stages, saury is gradually becoming a special breeding object with high economic value, but the breeding technology and breeding conditions are still immature and need to be gradually improved. At present, many are cultivated in outdoor earthen ponds, which results in low breeding density,...

AI Technical Summary

Problems solved by technology

The construction of large-scale dams has changed the original reproductive migration route of saury, and the pollution and destruction of the ecological environment have threatened the survival of saury. Therefore, the overall number of saury has been greatly reduced compared with before. Phased breakthrough, saury is gradually becoming a special breeding object with high economic value, but the breeding technology and breeding conditions are not yet mature, and need to be gradually improved

At present, many of them are cultivated in outdoor earthen ponds, which results in low breeding density, extremely low yield, increased risk, and excessive dependence on the environment, which restricts the large-scale production of saury. It is necessary to provide a kind of factory ecological farming of saury Technology to improve large-scale farming of swordfish
