Problems solved by technology

[0003] Long thin loach has great market prospects, and the requirements for the breeding environment are not high. In view of the sharply reduced resources of long thin loach and good prospects for development and utilization, but the resources of wild long thin loach are small, and the problems in artificial domestication, breeding and breeding have not been completely solved. Artificial breeding is less

Abstract

The present invention discloses a leptobotia elongata fry cultivation method. The method includes the following steps: building a leptobotia elongata cultivating pool, culturing water, releasing fries, feeding the fries with starter feed, further feeding the fries, breeding the fries, and collecting the fries. According to the present invention, the leptobotia elongata cultivating pool is a long rectangular cement pool; fine sand with a thickness of 5cm covers the bottom of the cultivating pool; the leptobotia elongata cultivating pool adopts a bottom drainage method to drain the water; and chlorine dioxide with a concentration of 2 to 4g per cubic meter is used to disinfect cultivating pool water body. The leptobotia elongata fry cultivation method has the following beneficial effects that the leptobotia elongata fries are carefully cultured from a spray stage to a stage that the leptobotia elongata fries have a length of 3 to 4cm; the cultured leptobotia elongata fries are strong in body and uniform in specification; the fry survival rate of the leptobotia elongata fries is improved; and thus, the adult leptobotia elongata breeding efficiency can be ensured.

Description

technical field [0001] The invention relates to a method for cultivating long thin loach seedlings, belonging to the technical field of long thin loach cultivation. Background technique [0002] Long thin loach belongs to the Loach family and belongs to the genus Boloach. It is distributed in the middle and upper reaches of the Yangtze River and its tributaries. Long thin loach is a nocturnal fish. It mainly feeds on aquatic insects and other benthic invertebrates. It also eats plant debris, algae, and plankton. It is a highly economical fish species with nutritional and medicinal values. higher. [0003] Long thin loach has great market prospects, and the requirements for the breeding environment are not high. In view of the sharply declining resources of long thin loach and good prospects for development and utilization, but the wild long thin loach has few resources, and the problems in artificial domestication, breeding and breeding have not been completely solved. Art...
