Abstract

The invention relates to a culture method of the red drum. The culture method of the red drum includes selecting a mariculture area, setting cages, selecting and throwing in fry, changing nets, separating the fry, and feeding with feed. By the culture method using a compensatory growth mechanism, feeding time is saved, labor and feed are reduced, utilization rate of the feed is increased, culturing cost is saved, and economic cultural benefit is increased. In addition, hungry fishes of the red drum consume body fat to maintain physiological function, and accordingly the red drum cultured by the culture method have fat content 0.4-0.6% lower than that of the conventionally cultured red drum, and protein content increased by 6-9%. The requirement for low fat and high protein is met, and human health is benefited.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding methods, in particular to a method for cultivating American redfish. Background technique [0002] Since the 1980s, global marine fishery resources have seriously declined due to excessive fishing, environmental pollution, and production damage. Marine fishing can no longer meet people's demand for aquatic products, especially high-quality aquatic products. The focus of fishery production has shifted from the traditional hunting-style marine fishing fishery to the animal husbandry-style marine aquaculture industry. The marine fish aquaculture industry has developed rapidly in recent years. American Redfish Sciaenops ocellatus (Linnaeus), the scientific name is the eye-spotted totoaba, also known as the red fish and the spotted perch, which belongs to the order Perciformes and the genus Pseudo-totoaba. . American redfish has the advantages of strong disease resistance, rapid growth, la...
