Abstract

The invention discloses a sillago sihama high-density pond culture method and belongs to the field of aquaculture. According to the method, a pond which is located above an intertidal zone or a cement or mulch slope and provided with middle pollution discharging, seawater processing and oxygenation facilities is used for conducting sillago sihama high-density pond culture, wherein the bottom layer of the pond is paved with sand, and the area of the pond ranges from 0.07 hm<2> to 0.2 hm<2>. According to the method, a large amount of benthos and zooplankter in the pond are fully utilized as bait, sillago sihama is fed with full artificial mixed feed, and the sillago sihama can reach the commercial specification after being cultured for 80 days to 120 days. The method is suitable for ponds paved with films, intensive culture cement ponds and winter shed ponds, space is expanded for scale culture of sillago sihama, the new brand is added for marine fish culture, and the method has far-reaching significance in marine fish culture structure adjustment.

Description

technical field [0001] The invention relates to a high-density cultivation method of fish in ponds, in particular to a high-density cultivation method of multi-scale carp in ponds, and belongs to the technical field of aquaculture. 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 population is getting smaller, and the out...
