Problems solved by technology

[0003] At present, the conventional method of cultivating river prawns comprises the following steps: 1) pond selection; 2) shrimp seedlings are put in a suitable place to breed; 3) bait throwing management; bait mainly relies on the plankton in the pond for food, supplemented with fresh fish, shellfish etc. again, this This method is based on meat, although it can speed up the growth of river prawns, but the meat feed will produce a lot of bacteria and parasites, resulting in low survival rate and low quality of river prawns

Abstract

The invention provides an environment-friendly river prawn culture method. The environment-friendly river prawn culture method includes the steps of 1) building a pond; 2) selecting young prawns; 3) carrying out water treatment before young prawn releasing; 4) fertilizing and culturing baits; 5) releasing the young prawns; 6) conducting bait casting management; 7) conducting water transfer management. The environment-friendly river prawn culture method has the advantages that different traditional Chinese medicine additives are added from a first stage to a third stage according to the growth characteristics of the prawns during bait casting management, immunity can be enhanced at the first stage to prevent various diseases and increase the survival rate in the young prawn period, the traditional Chinese medicine additives added at the second stage play a direct role in antibacterial and antiviral effects and killing pests so as to increase the survival rate, and the traditional Chinese medicine additives added at the third stage are capable of improving the water quality and freshening the prawns.

Description

【Technical field】 [0001] The invention relates to a cultivation method, in particular to an environment-friendly cultivation method for river prawns. 【Background technique】 [0002] The meat of river prawns is tender, delicious and nutritious.
