Method and facility for cultivating parents of Sillago sihama indoors on large scale via prawn cultivation wastewater

Abstract

The invention discloses a method and a facility for cultivating parents of Sillago sihama indoors on a large scale via prawn cultivation wastewater and belongs to the technical field of artificial breeding of fishes. The facility is composed of two to three prawn cultivation ponds 0.07 to 0.2 hm<2>, two to four outdoor cultivation wastewater degrading pools 50M<3> in volume, a parent cultivation cement pond located in an indoor controllable light parent cultivation shop, and a water pumping system. The cultivation wastewater obtained in mid-late phase of prawn cultivation is biologically treated, organics in the cultivation wastewater are degraded, and the cultivation wastewater is then used in the indoor cement pond for cultivating the parents of Sillago sihama on the large scale, animal planktons in the degraded water are used as feed additive for the parents, the lost nutrition in compound feed can be supplemented, and female and male parents are enabled to be more mature; microalgae are good for stabilizing the parent cultivation water. The method has the advantages that the prawn cultivation wastewater is made effective use, environment pollution is decreased, survival rate of Sillago sihama cultivated on the large scale in the indoor shop is increased, and quality of zygotes is increased.

Description

technical field

[0001] The invention relates to a method for large-scale cultivation of broodstock of the multi-scaled carp, in particular to a method and facility for indoor large-scale cultivation of the broodstock of the multi-scaled carp by using prawn breeding wastewater, and belongs to the technical field of fish artificial breeding. Background technique

[0002] Multi-scaled Chick Sillago sihama Forskál , commonly known as sand drill, boat dingle, wheat ear, body length can reach 300mm, belonging to Perciformes Perciformes Perch Percoidei Superfamily Percoidea , Chiidae Silaginidae , genus Sillago . Widely distributed in my country's coastal areas and Australia, India, Indonesia, Philippines and Japan. The fishing season is spring and summer. It is an important economic fish in my country's coastal areas. It used to occupy a very important position in offshore fishing operations. However, due to overfishing in recent years, individuals have become younger a...
