Abstract

The invention discloses a special feed for maintaining water quality for crayfish. The special feed comprises the following raw materials in parts by weight of 8-16 parts of corn flour, 4-8 parts of meat and bone meal, 6-14 parts of sweet potato vines, 10-20 parts of mulberry leaves, 125-130 parts of a protein additive, 0.2-0.4 part of calcium hydrogen phosphate, 0.02-0.04 part of an enzyme preparation, 3-5 parts of an immune enhancer, 2-4 parts of a phagostimulant, and 4-8 parts of a shaping agent. The shaping agent is prepared through the following technologies of stirring chloro-PEG400 andbeta-cyclodextrin, performing warming, sequentially adding sodium hydroxide, sodium dodecylsulfate and nitrogen protection under the stirring state, under nitrogen protection, regulating the temperature, performing stirring, performing cooling, regulating the system with hydrochloric acid to be neutral, performing filtering, washing filtrate with anhydrous ethanol, and performing drying to obtainthe shaping agent. The water quality of a pond can be maintained, a favorable ecological environment can be established, the constitutions of the crayfish can be improved, and the mortality is reduced.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a special crayfish feed and a cultivation method for maintaining water quality. Background technique [0002] The history of eating freshwater crayfish in our country began in the 1960s. With consumers' awareness of freshwater crayfish and the extensive promotion of the media, freshwater crayfish food has generally entered restaurants, hotels, supermarkets and family tables, and the sales market The increase in demand has caused a sharp decrease in natural resources and rising prices. Freshwater crayfish have become a hot-selling aquatic product in the market. [0003] The existing lobsters cause water pollution due to the easy deterioration of the feed during the breeding process, and the crayfish has a high mortality rate, which is unhealthy and safe to use, and the shrimp body is not large enough. Contents of the invention [0004] Based on the technical proble...
