System and method for cultivating anguilla marmorata

Abstract

The invention relates to the field of aquiculture, in particular to a system and method for cultivating anguilla marmorata. The system for cultivating anguilla marmorata comprises a water purifying system and an anguilla marmorata pipeline perching system, wherein the water purifying system is used for decomposing and absorbing the excretion of the anguilla marmorata and organics in the anguilla marmorata cultivating system so as to ensure the water quality of the anguilla marmorata cultivating system, avoid using too much fresh water, reduce the pressure of the environment from the anguilla marmorata cultivating system, save electric consumption, and reduce the cultivating cost of the anguilla marmorata; simultaneously, the anguilla marmorata pipeline perching system improves the cultivating density of the anguilla marmorata and reduces the cannibalism rate of the anguilla marmorata. Compared with a running water open type cement pond cultivating method, the cultivating method of theanguilla marmorata cultivating system disclosed by the invention improvise the production rate of the anguilla marmorata by more than 25%, saves power consumption and fresh water resource by more than 40%, increases the amount of the anguilla marmorata cultivated in per square meter of water by more than 50%, and enhances the the comprehensive cultivating benefit by about 45%.

Description

Technical field [0001] The invention relates to the field of aquaculture, in particular to a flower eel breeding system and a breeding method. Background technique [0002] The flower eel (Anguilla marmorata; marbled eel) is a kind of Chordate, Vertebrate subphylum, Bonefish, Radial fin subclass, Anguillae, Anguillae, Anguidae, and Eel genus. Eel is the most widely distributed species in the world, from Jeju Island in South Korea in the north, Ogasawara Islands in the east, Marquesas Islands in the South Pacific in the south, and Natal on the east coast of Africa in the west. In China, it is distributed in various river systems from Qiantang River to Hainan Province. It inhabits in crevices and caves in estuaries, mountain streams, valleys and reservoirs. Flower eels are fierce, often active at night, feed on small fish, shrimps, crabs, etc., and are migratory fish that spawn in the lower river. In Jiulong River, Fujian, China, he lives in caves in Zhongying Rivers and Creeks ...

AI Technical Summary

Problems solved by technology

At present, the breeding of flower eels mainly adopts the extensive farming mode in earthen ponds. Although this farming method has a faster growth rate, it occupies a large area, has low yield per unit area, and wastes a lot of water resources; and because flower eels are very easy to escape, the catch rate is very low Low; in addition, because the flower eel has a strong ability to drill holes, it has a greater destructive force on the dam foundation of the earthen pond, so the economic benefits of flower eel cultivation in earthen ponds are not high

In recent years, the cultivation of flower eels in cement ponds has gradually expanded. Although cement pond cultivation has basically solved the problem of flower eels escaping, the growth speed of flower eels is slow, the breeding density is low, and the water and electricity consumption is large, and the cost is high. , the pressure on the environment is also greater

Therefore, at present, flower eels, a product with high market value, have not reached the level of large-scale commercial farming.
