Problems solved by technology

Most of the medicines currently on the market for supplementing the calcium and trace elements needed by shrimps and crabs have single ingredients. Using a certain product alone cannot supplement nutrition systematically and comprehensively, and the effect is not obvious. However, repeated use of different medicines has improved The cost of farming increases th

Abstract

The invention discloses a nutrient composition for enhancing shell hardening speed of shrimp and crab. The composition comprises the following components in percentage by weight: 1-50% of calcium gluconate, 1-40% of shell factor, 1-40% of immunity enhancement factor and 1-40% of traditional Chinese medicine anti-stress factor. The nutrient composition contains a plurality of active ingredients indispensable for aquatic animal growth, effectively enhances calcium, increases shell hardening speed, effectively improves the immunity of the shrimp and crab organisms, supplements indispensable mineral matters and microelements in a shrimp and crab culturing water body, accelerates the shell hardening of the shrimp and crab, prevents the failure of the shrimp and crab shelling and has the advantages of no toxic or side effect or medicament residue, convenient use and low cost.

Description

technical field [0001] The invention belongs to the field of nutritional agents for aquaculture animals, in particular to a nutritional composition for enhancing the hard shell speed of shrimps and crabs and its preparation method and application. Background technique [0002] China is the country with the largest amount of aquaculture in the world. In recent years, the aquaculture area of ​​lakes, rivers, sea areas, reservoirs, and paddy fields in China has gradually expanded, and the departments of agriculture, fishery, and water conservancy are all involved in aquaculture. With the rapid development of my country's freshwater shrimp and crab aquaculture industry, the continuous expansion of the aquaculture area and production scale, the sharp increase in aquaculture production and the continuous improvement of the degree of intensification, many potential technical problems have gradually been exposed. Prevention and treatment are also getting more and more attention. Mos...
