Abstract

The invention relates to a feed, specifically to a feed for river crab breeding. The feed comprises, by weight, 10 to 30 parts of fishbone dust, 20 to 30 parts of dried silkworm chrysalis, 5 to 10 parts of dried fish meal, 10 to 20 parts of shrimp shell powder, 6 to 10 parts of fish intestine powder, 3 to 8 parts of fermented duck blood powder, 3 to 6 parts of soybean lecithin, 1 to 5 parts of spirulina, 12 to 16 parts of chicken skin powder, 5 to 10 parts of duck skin powder, 6 to 10 parts of egg white powder, 0.7 to 1.1 parts of olive oil, 0.3 to 0.5 part of calcium lactate and 3 to 5 partsof yeast powder. The feed prepared in the invention is rich in nutrients, can obviously improve the immunity of young river crabs, improves the survival rate of river crabs and has good palatability.

Description

Technical field [0001] The invention relates to a feed, in particular to a feed for breeding river crabs. Background technique [0002] River crabs are seriously deficient due to natural adult crabs. At present, large-scale and large-scale artificial breeding is carried out in aquaculture farms. Due to the large-scale artificial breeding of crabs when the breeding density is high, the ecological environment for raising crabs is poor, and the aquatic plants and aquatic animals eaten by river crabs are seriously insufficient, and crabs need to be supplemented with a larger amount of bait. The quality of the bait directly affects the growth rate, quality, grade, economic benefits of crab farmers and the overall ecological, economic and social benefits of crab farming. Summary of the invention [0003] The purpose of the present invention is to provide a feed for breeding river crabs, which is rich in nutrients, can significantly enhance the immunity of lobster juveniles, and has go...
