Preparation method of feed for healthy and high-yield cultivation of freshwater shrimps

Abstract

The invention discloses a preparation method of a feed for healthy and high-yield cultivation of freshwater shrimps. The method comprises the steps of (1) raw material selection, (2) drying and crushing, (3) mixing, (4) fermentation, and (5) addition of preparations to obtain the finished feed. The preparation method of the feed for the healthy and high-yield cultivation of the freshwater shrimps is simple and convenient to operate, and easy to implement; the prepared feed provides organic matters, inorganic mineral substances and microelements essential to the growth of the freshwater shrimps according to the growth characteristics of the freshwater shrimps, and provides balanced nutrient substances such as proteins, amino acid and reproduction accelerants for the growth of the freshwater shrimps; in addition, the feed does not contain toxic or side components such as drugs and does not pollute a water body; toxic substances such as nitrite and sulfide in water can be decomposed by using fungi contained in the feed, and a good water quality regulation effect is achieved.

Description

[0001] technical field [0002] The invention relates to the technical field of aquaculture, in particular to a method for preparing feed for healthy and high-yield cultured freshwater shrimp. Background technique [0003] Freshwater freshwater freshwater prawn, scientific name Macrobrachium nipponense, belongs to crustaceans, decapods, swimming suborders, true shrimp pie, long arm family, macrobrachium genus, a kind of freshwater prawns with a large number, and my country's freshwater aquaculture industry One of the traditional economic shrimp species in China. Freshwater prawns are rich in nutritional value and delicious in meat quality, and are deeply loved by consumers. [0004] Feed is one of the key factors that determine the quality and growth rate of freshwater shrimp. Most of the current freshwater shrimp breeding feeds use ordinary aquaculture feeds, which are poor in pertinence and high in drug content. During the freshwater shrimp breeding process, a series of w...

Problems solved by technology

Most of the current freshwater shrimp breeding feeds use ordinary aquaculture feeds, which are poor in pertinence and high in drug content. During the freshwater shrimp breeding process, a series of water pollution problems have been generated due to the large input of feed after high-density stocking. The output and quality of freshwater shrimp have declined, and the development of green shrimp farming industry has been slow, which cannot meet the consumption demand of the market
