Industrialized ecological breeding method for shrimp seeds with high stress resistance and disease resistance

Abstract

The invention relates to the technical field of marine seed breeding, in particular to an industrialized ecological breeding method for shrimp seeds with high stress resistance and disease resistance. The industrialized ecological breeding method comprises the following steps of (1) establishment of a seed breeding pond, (2) treatment of the seed breeding pond, (3) treatment of seed breeding pond water, (4) regulation of the seed breeding pond water, (5) selection of healthy and high-quality shrimp seeds, (6) PCR virus detection, (7) seed putting preliminary treatment, (8)seed putting pretreatment, (9) seed putting management and (10) later period cultivation. According to the method, firstly, judgment is conducted on the health of the shrimp seeds, then the shrimp seeds which are healthy, high in quality and high in disease resistance are selected, and then the seed putting pretreatment, the seed putting management and the later period cultivation are sequentially conducted in the seed breeding process, so that a stress reaction of the shrimp seeds can be relieved during the seed putting pretreatment to recover the physical strength of the shrimp seeds, the physique of the shrimp seeds can be effectively strengthened through the seed putting management, calcium required by the shrimp seeds during exuviation growth can be provided during the later-period cultivation, and then the stress resistance and the disease resistance of the shrimp seeds are improved.

Description

technical field [0001] The invention relates to the technical field of marine seedling breeding, in particular to an industrialized ecological seedling raising method for shrimp seedlings with high stress resistance and disease resistance. Background technique [0002] As a high-quality seafood, prawns are popular in domestic and foreign markets, and the demand for high-quality prawn products is increasing. Shrimp farming has become a dominant industry in my country's fishery industry and an important way for Chinese fishermen to get rich. However, in recent years, due to the continuous degradation of the quality of shrimp cultured species, the lack of good alternative species and the lagging of breeding technology for improved species, it is difficult to breed high-quality shrimp seedlings, and with the deteriorating water quality of the breeding environment, extreme weather often occurs , leading to frequent occurrence of various diseases, low success rate of shrimp farmin...
