Industrial cultivation method for seriola aureovittata fries

Abstract

The invention relates to an industrialized breeding method for seriola aureovittata, and belongs to the technical field of marine fish culture, and the method comprises cultivation facility, fertilized egg incubation management, bait series and feeding strategy, environment regulation and control management and intermediate cultivation. According to the method, night illumination is set on the water surface of the culture pond, flow generation and sedimentation prevention are conducted in the culture pond, bait series are diversified, bait conversion is induced through hanging rods, low-stress grading screening is conducted, the survival rate of fry culture is increased, fry growth and development are promoted, high-quality seriola aureovittata fry are cultured in batches, and the survival rate of fry culture is increased. And a seedling guarantee is provided for development of the deep and far sea culture industry.

Description

technical field [0001] The invention belongs to the technical field of marine fish culture, and in particular relates to an industrialized seedling raising method for yellowtail yellowtail. Background technique [0002] Yellowtail (Seriolalalandi) belongs to the order Perciformes, Carangidae, and Seriola. It is an oceanic economic fish widely distributed in the middle and upper waters of the world's oceans and is distributed along the coast of my country. . Yellowtail has the characteristics of large size, fast growth, delicious meat and rich nutrition. Its nutritional quality and taste are comparable to salmon and tuna. It is a high-end ingredient for making sashimi and sushi. Favored, the market demand is large, and the development prospect is good. Yellowtail is not only suitable for industrial recirculating aquaculture, but also an ideal fish for deep-water large-scale aquaculture facilities such as deep-water storm-resistant cages, large fences, and aquaculture vessels...

AI Technical Summary

Problems solved by technology

Although since the 1990s, Japan and other countries have started research on the artificial breeding technology of yellowtail amberjack in the world, but the large-scale seed breeding technology has not yet been broken in the world. The number of seed breeding in Japan, Australia and other countries is only It is 100,000 to 200,000 fish, and the seedling cultivation technology is unstable, and the annual number of seedlings can fluctuate greatly, which is far from meeting the needs of the aquaculture industry. It has become a bottleneck restricting the development of the yellowtail aquaculture industry. It is urgent to establish a stable seedling The breeding technology system realizes the large-scale cultivation, production and supply of high-quality yellowtail seedlings, and supports the sustainable and healthy development of the breeding industry
