Abstract

The invention aims at providing a method and use feed for artificial reproduction of lateolabrax maculatus. The use feed for the artificial reproduction of the lateolabrax maculatus is prepared from main materials and additives, wherein the main materials comprise lateolabras maculatus matched feed, trash fishes of mullets, coilias, mackerels and the like, fresh shrimps, squids and oysters; the additives comprise vitamin B12, vitamin C, vitamin E and gonad maturation promoting treasure. The preproduction method comprises the following steps: firstly, screening parent fishes and improving nutrient; secondly, ripening and carrying out artificial propagation; thirdly, collecting and incubating fertilized eggs. The method has the advantages that physique of the parent fishes can be significantly enhanced, the development of gonad is promoted, the quality of sperms and eggs is optimized and the quality of gametes is improved; meanwhile, the repeated utilization rate of the parent fishes isimproved; by using proper drug dose of ripening and artificial propagation, the parent fishes can concentrate on spawning, so that the labor intensity and reproduction cost of artificial reproductionare reduced; the method for the artificial reproduction of the lateolabrax maculatus has high success rate, so that the yield of lateolabrax maculatus fries can be effectively improved and the demandsof large-scale culturing are met.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificial propagation of sea bass and the feed used therefor. Background technique [0002] Lateolabrax maculatus, also known as sea bass and seven-star perch, belongs to the order Perciformes, the family Serranidae, and the genus Lateolabrax. Its meat is delicious and nutritious, and is deeply loved by consumers. At the same time, the perch grows fast and has a wide range of adaptability to salinity and temperature. It has become one of the important breeding species in coastal areas of China. In 2017, the national perch breeding The output reached 156,600 tons. [0003] Based on the huge breeding prospects, the large-scale and stable seed supply of sea bass has become an urgent need. At present, the artificial breeding technology of sea bass is very mature, but the traditional breeding methods still have poor quality of broodstock, easy to die in operation, a...
