Example Embodiment

[0075] Example 1

[0076] The method for non-resistant ecological cultivation of crayfish in this embodiment includes the following steps:

[0077] (a) Disinfection treatment of breeding ponds: use quicklime to disinfect the breeding ponds: when the water level is within 10 cm, the amount of quicklime is 30-50kg / mu, and when the water level exceeds 10 cm, the amount of quicklime is 100-150kg / mu;

[0078] (b) Choose crayfish seedlings for the next pond: choose seedlings that are bright and shiny, have a smooth body surface without attachments, complete appendages without damage, and have strong physical fitness and vigor;

[0079] Before the seedlings are put into the breeding pond, the water is tested first, and then soaked in salt water with a mass fraction of 3% for 5 minutes to kill the parasites and harmful bacteria; and then put into the breeding pond.

[0080] (c) Improving the breeding environment: after the pond, during the breeding process, add granular biological fertilizer at...

Example Embodiment

[0096] Example 2

[0097] This embodiment refers to the cultivation method of embodiment 1, the only difference is: step (b) does not use salt water soaking, but uses a gold multi-dimensional solution with a mass fraction of 3% to soak the seedlings for 5 minutes before putting them.

Example Embodiment

[0098] Example 3

[0099] This embodiment refers to the breeding method of Example 1. The only difference is: the feeding of the feed in step (d) only uses the conventional feeding, and the feed mixed with bacillus is not fed.

Abstract

The invention relates to the technical field of aquaculture, in particular to an antibiotics-free breeding method for crayfishes. The antibiotics-free breeding method for the crayfishes comprises thefollowing steps that young crayfishes are put into a breeding pond, and feed, biological fertilizer, microbial bottom improvement substance, water quality regulator and algae cultivation substance areput into the breeding pond in the breeding process. According to the method, with breeding environment improvement and micro-ecological health care as principles, antibiotics, hormones or exogenous chemical drugs are not needed in the breeding process, the maintenance of aquatic plants in the breeding pond is improved, organic sewage at the bottom of the breeding pond is dissolved and oxidized, and the bottom dissolved oxygen is increased; organic matter, residual bait, excrement and the like are decomposed, the disease resistance and stress resistance of the crayfishes are improved, breedingof water-extraction beneficial algae is promoted, and the pH value is stabilized; waterborne plankton is cultivated, the algae are stabilized, the water is rich in plankton, capable of keeping flowing, tender and fresh, the breeding environment in the growth process of the crayfishes is improved, the survival rate of the crayfishes is increased, and the health condition of the crayfishes is improved.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to an antibiotic-free ecological cultivation method of crayfish. Background technique [0002] Crayfish are also called Procambarus clarkii, red crayfish and freshwater crayfish. They are shaped like shrimps and have a hard shell. The adult body is about 5.6-11.9 cm long, dark red, the carapace is almost black, and there is a wedge-shaped stripe on the back of the abdomen. Crayfish is a freshwater economical shrimp with high nutritional value and contains 8 essential amino acids needed by the human body. It is widely welcomed by people because of its delicious meat, so the breeding technology of crayfish is developing rapidly. [0003] Due to the obvious economic benefits of using antibiotics in the breeding process of crayfish, and the poor health of crayfish under high-density and large-scale farming conditions, crayfish farming generally relies on antibiotics,...
