A kind of method of industrialized breeding four-fingered horsefin

Abstract

A method for industrialized cultivation of four-fingered horsefin of the present invention belongs to the technical field of fish cultivation, and comprises the following steps: 1) preparing cultivation conditions: establishing and disinfecting cultivation circulation equipment, said cultivation circulation equipment including cultivation tanks and precipitation The pond and the biochemical pond are circulated and connected; the aquaculture water is recycled through the aquaculture circulation equipment, and the aquaculture water is prepared by mixing natural seawater and tap water; 2) Fish fry transportation and delivery: choose fish fry with a length of 0.8~2.0 cm for transportation, Use plastic bags filled with aquaculture water and sufficiently oxygenated for transportation, and add a carrier for absorbing vegetable oil, then adapt and disinfect the fry, and then put the fry into the culture tank for cultivation; 3) Manage the feeding of fish; 4) Stress control and management of fish; 5) Disease control of fish. The invention can realize large-scale seed cultivation and in-situ cultivation of adult fish in artificially prepared seawater closed circulating water for the four-fingered horsefin.

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.
