Pelletized feed for adult fish of Leiocassis Longirostris

Abstract

The present invention discloses a complete nutrient pelletized feed for longnosed wei fish. Said feed is formed from fish powder, soybean cake, rape cake, corn flour, edible oil, mixed vitamins, mixed mineral salt and additive.

Description

technical field [0001] The invention relates to fish breeding feed, in particular to a full-nutritional granular feed for adult long-snout catfish. Background technique [0002] Long snout is a relatively large economic fish in the Yangtze River. Because of its delicious meat and no spines, it is a high-quality fish; and because of its thick swim bladder, it can be dried into valuable fish maw. Deeply loved by consumers. [0003] Due to the increasingly serious pollution of rivers and long-term indiscriminate fishing, the resources of long-snout catfish in the Yangtze River have been severely damaged, and its annual output has dropped sharply, which has been unable to meet the needs of the market and people's lives. In order to meet the needs of the market and the structural adjustment of my country's agriculture and aquaculture, the artificial breeding of long-snout catfish has developed rapidly in the past two decades, and the technologies in artifi...

AI Technical Summary

Problems solved by technology

The artificial breeding of compound feed that does not follow the nutritional standards and feed technology of the cultured species will inevitably lead to a decline in the quality of the cultured products and the effect of the feed, and will lead to waste of feed and increase in breeding costs and water pollution.

At present, due to the lack of water resources, the scale of aquaculture is limited, and the quality of aquaculture products is affected
