Indoor cement pond culture technique of Yangtze River Coilia ectenes

Abstract

The invention relates to an indoor cement pond culture technique of Yangtze River Coilia ectenes, belonging to the field of Coilia ectenes culture. The indoor cement pond culture technique of the Yangtze River Coilia ectenes comprises the steps of fingerling acquisition and transportation, temporary culture and domestication, indoor culture and overwintering culture. The indoor cement pond culture technique of the Yangtze River Coilia ectenes is characterized in that juvenile fish with body length being 8-12cm is acquired in September to October and is put in an indoor cement pond for temporary culture; after the juvenile fish is domesticated for 2-4 weeks, the juvenile fish is transferred into an indoor small cement pond for culture; when the juvenile fish is cultured to November to December of each year and the water temperature is below 15DEG C, the Coilia ectenes is transferred for the overwintering culture, the overwintering culture of the Coilia ectenes is conducted at room temperature and the water temperature is kept above 8DEG C to keep the juvenile fish to intake food; during overwintering, live seawater copepods are used as fish feed, and if the live fish feed is not enough, the live fish feed can be replaced by frozen opossum shrimps or slow-sinking compound feed; and after the spring of the next year begins, the juvenile fish is cultured according to the indoor culture method.

Description

technical field [0001] The invention relates to the cultivation of the common anchovy, in particular to the indoor cement pond cultivation technology of the anchovy from the Yangtze River. Background technique [0002] Coilia ectenes, belonging to the order Herringoformes, Anchovyidae, and Anchovy, are commonly known as saury, hairy saury, hairy flower fish, bearded fish, and anchovy. It is mainly distributed in the Yellow Bohai Sea and the East China Sea in my country. It can be seen in all the rivers that lead to the sea, such as the Liaohe River, the Haihe River, the Yellow River, the Yangtze River, and the Qiantang River. It is famous for its tender meat and delicious taste. rare migratory fish. In recent years, due to the influence of many factors such as overfishing and the deterioration of the ecological environment, the resources of anchovy have declined sharply, while the market demand has continued unabated, and even reached the dilemma of having a price but no mar...

Problems solved by technology

[0005] The outstanding feature of the present invention relative to the extensive culture technology of existing cuttlefish pond is: 1) indoor cuttlefish culture density (5-10 tail / m 2 ) than extensive pond culture (1-2 tails / m 2 ) is much higher, which saves the breeding space, improves the breeding output and economic benefits; 2) the cultivation of the cuttlefish is carried out under the artificial controllable environment, which increases the controllability of the cultivation of the cuttlefish and improves the management level of the cultivation; 3) Alleviate the problems of wildness, violent temperament, unsuitable for human operation, and the survival rate of batch transportation of ecologically cultured anchovy, and the survival rate of transportation is 70-85%; 4) Solve the problem of difficult operation of anchovy brood during artificial breeding of anchovy , the survival rate of temporary breeding and domestication is 50-80%, and the survival rate of indoor breeding is 70-90%
