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 a
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.
