Problems solved by technology

Due to the influence of various factors such as the biological characteristics of freshwater shrimp, the growth and distribution of aquatic plants, the stocking density of freshwater shrimp is generally 100,000-120,000 / mu, but the sum of large and small shrimps is generally 3,200 to 5,000 when harvested. Between tails, the survival rate is only between 30% and 40%

Embodiment 3

[0047] In Dapu Base of Freshwater Fishery Research Center of Chinese Academy of Fishery Sciences in Yixing City, two ponds with an area of ​​2 mu were selected for breeding and breeding of freshwater shrimp. One was the control group, fed compound feed without compound drugs, and the other The experimental group was fed with compound feed containing 1% compound drug. The green shrimp seedling density that puts into each breeding pond is 110,000 tails / acre.

[0048] Basic ration configuration: configure the basal ration by weight percentage, the protein level is 42%, the crude fat level is 5.8%, the fishmeal level content is 25%, the lysine content is 2.2%, and the methionine content is 1.0%.

Abstract

The present invention provides a medicine, a feed and a method for preventing fighting and self-disability of cultured macrobrachium nipponense. 0.5%-1% by mass of the medicine is added into a basic daily ration, and feeding is conducted twice everyday in the morning and evening; residual baits are fished out 1 hour after the feeding; in cloudy and rainy days, feeding is conducted once or not; avoiding pipes are arranged at positions, where no grass is planted, in breeding areas and the three-dimensional avoiding positions are provided for the macrobrachium nipponense; and the medicine comprises 30-40 g of spina date seeds, 30-40 g of platycladi seeds, 8-20 g of L-tryptophan, 2-5 g of dimethyl-beta-propiothetin (DMPT), 2-5 g of plant essential oil and 0.5-1.0 g of ferulic acid. The methodrelieves fighting and self-disability states of the macrobrachium nipponense, improves a survival rate of the macrobrachium nipponense in a breeding process, and is easy and convenient to operate andlow in cost.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and relates to aquaculture management, in particular to medicine, feed and a method for preventing aquaculture freshwater shrimp from fighting and self-mutilation. Background technique [0002] Freshwater prawn, commonly known as river prawn, scientific name Japanese river prawn (Macrobrachium nipponense), is a native species of my country. Because of its tender meat and delicious taste, it is deeply loved by consumers and has formed large-scale farming. It is an important freshwater cultured shrimp in my country. Freshwater shrimp is a benthic animal with poor swimming ability. It likes to attach to aquatic plants and climb for short distances. It consumes high oxygen and is not suitable for survival in low-oxygen environments. [0003] When freshwater shrimp is raised, aquatic plants such as Elodea and Hydrilla verticillium are usually planted in the shrimp pond. The aquatic plants can not ...
