Method for industrial breeding of elentheronema tetradactylum

Abstract

The invention relates to a method for industrial breeding of elentheronema tetradactylum, and belongs to the technical field of fish breeding. The method comprises the following steps of 1, preparation of breeding conditions, wherein breeding circulation equipment is established for disinfection and comprises a breeding barrel which is circularly communicated with a sedimentation tank and a biochemical tank, and breeding water is recycled through the breeding circulation equipment and prepared by mixing natural seawater with tap water; 2, transportation and putting of fry, wherein fry with the length of 0.8-2.0 cm are selected for transportation, plastic bags which contain the breeding water and sufficient oxygen are adopted for transportation, carriers for adsorbing vegetable oil are added, environmental adaptation and disinfection treatment are carried out on the fry, and then the fry are put into the breeding barrel for breeding; 3, feeding management of fishes; 4, stress control and management of the fishes; 5, disease prevention and control of the fishes. The method can realize large-scale fry cultivation in sealed circulating water prepared from artificial seawater and in-situ breeding of adult fishes for elentheronema tetradactylum.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a method for industrially cultivating four-fingered horsefin. Background technique [0002] Four-fingered horsefin (Elentheronema tetradactylum), commonly known as Wuyu and Mayou, is a warm and eurysaltic fish, mainly distributed in tropical and subtropical seas, and also in the Bohai Sea, Yellow Sea, and East my country Sea. It likes to inhabit offshore waters. , river estuaries and other waters, make good use of the free soft strips of pectoral fins to detect shrimps, cephalopods, amphipods and small fish. In 2015, the large-scale artificial breeding process of four-fingered horsefin was realized in China. Because of its wide range of salinity adaptation, fast growth, delicious meat, no intercostal thorns, and high economic value, it has formed a certain breeding scale in my country. It is also one of the marine cultured fish species promoted by the Food and Agr...

Problems solved by technology

Due to the strong stress of four-fingered Spanish finfish fry, it is easy to cause a large number of deaths, and its industrial farming has not been successful.

[0004] At present, the four-fingered horsefin is mainly cultivated in ponds, and it is generally mixed with other fish. Pond cultivation needs to occupy more land and water resources. The controllability of environmental factors is poor, and the fish body is highly stressed. Pond cultivation requires Supplemented by insulation measures such as winter sheds, it is possible to survive the winter. Pond farming can easily cause differences in fish specifications.
