Abstract

The present invention discloses a special crayfish feed for improving survival rate. The feed comprises the following raw materials in parts by weight: 30-40 parts of puffed blood powder, 10-20 partsof earthworm powder, 20-30 parts of coconut meal, 40-50 parts of whey protein powder, 20-30 parts of corn germ protein powder, 20-30 parts of soybean milk powder, 25-35 parts of an immunopotentiator,0.02-0.04 part of selenium-enriched yeast, 0.02-0.04 part of pectinase, 0.04-0.08 part of monascus, 0.06-0.12 part of composite amino acid and 8-16 parts of an adhesive. The adhesive comprises olive oil, shell powder, montmorillonite and a tackifier. The tackifier is prepared by the following process: stirring sweet potato powder and hydrochloric acid, conducting filtration, drying and grinding, adding beta-cyclodextrin with stirring, adding sodium hydroxide with stirring, conducting stirring under the protection of nitrogen, conducting cooling, regulating the system with hydrochloric acid until the system is neutral, conducting filtration, washing filtrate with absolute ethyl alcohol, and conducting drying so as to obtain the tackifier.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a crayfish special feed and a cultivation method for improving the survival rate. Background technique [0002] Crayfish belongs to the genus Lobster of the family Arthropoda Molluscidae Decapod Lobster.
