Abstract

The invention discloses a sillago sihama fry mouth opening bait culturing, selecting and feeding method and belongs to the technical field of artificial fish breeding. Sillago sihama fry mouth opening bait is cultured and selected in a high-place pond which is disinfected through a dry method, and water in the high-place pond is disinfected. The sillago sihama fry mouth opening bait is obtained through the steps of water disinfection, fertilizer applying, chlorella culturing, basic bionic bait culturing, high-density zooplankton culturing, macrozooplankton restraining, microzooplankton collecting, selecting and other steps. The mouth opening bait can meet the requirement for nutrition for sillago sihama fry growing, and healthy growing of sillago sihama fry is promoted. The bait culturing, selecting and feeding method is simple and easy to implement. The sillago sihama fry mouth opening bait culturing, selecting and feeding technology can establish a technological basis for improving the sillago sihama fry artificial cultivation technology and adding a new band for marine fish culture in China, and has important significance in sillago sihama cultivation industrialization development.

Description

technical field [0001] The invention relates to a method for cultivating, screening and feeding fish bait, in particular to a method for cultivating, screening and feeding an open bait for larvae larvae, and belongs to the technical field of fish artificial breeding. Background technique [0002] Sillago sihama Forskál belongs to the order Perciformes, the suborder Percoidei, the superfamily Percoidea, the family Sillaginidae, and the genus Sillago. It is distributed in Australia, India, Indonesia, the Philippines and Japan. It is also distributed in the Bohai Sea, Yellow Sea, East China Sea and South my country Sea in China, with a body length of up to 300mm. Commonly known as sand drill, boat smallfish, and wheat ears, the multi-scaled carp is an important economic fish in my country's coastal areas and occupies a very important position in my country's offshore fishing operations. However, due to overfishing in recent years, the individuals are getting younger, the popula...
