Bottom-dwelling bait biological medium for freshwater shrimp culture and use method thereof

Abstract

The invention relates to a bottom-dwelling bait biological medium for freshwater shrimp culture and a use method of the bottom-dwelling bait biological medium. Bean meal, corn, cellulose, bagasse, vinasse, bran, bean dregs, rice bran, sodium humate, attapulgite, fluorspar powder, microbial organic fertilizer and organic matter are uniformly mixed to be made into a culture medium, and cultured bait organisms can replace more than 50 percent of artificial feed, so the culture cost is greatly reduced. Meanwhile, the high-quality bottom-dwelling bait organisms can provide the nutrition resources for the fast growth of freshwater shrimps, so the culture scale, the yield and the benefits are greatly improved. Through the produced high-quality freshwater shrimps, the market competitiveness can be improved, and the culture risk can be reduced.

Description

technical field [0001] The invention relates to a method for cultivating and multiplying benthic bait organisms and aquatic plants in the bottom mud of a pond to cultivate freshwater shrimp, especially a method for cultivating benthic baits such as water worms, snails and shellfish by using a culture medium placed in the bottom mud A method for cultivating freshwater shrimp with organisms and aquatic plants. Background technique [0002] Green shrimp is an indigenous species in my country, and it is distributed in waters such as rivers, rivers, lakes, ditches, canals, ponds and rice fields. Although the shrimp is small, it has the advantages of delicious taste, strong reproductive ability, and short breeding cycle. It has become one of the main species in the central and eastern regions of my country. The shrimp can propagate itself, so the catch of freshwater shrimp in natural waters occupies a relatively large proportion among freshwater shrimp species. At the beginning...

AI Technical Summary

Problems solved by technology

At the beginning of this century, artificial pond culture of freshwater shrimp entered the peak period of development, but the yield per unit area of ​​culture was still low. The reason was that the shrimp was too small and the killing rate was high, and the self-propagation ability was too strong. one

In the process of artificial breeding, the overbreeding of freshwater shrimp can easily lead to high breeding density, and the excessively high breeding density will lead to problems such as small size of commercial shrimp and decrease in added value. Therefore, how to improve the production of freshwater shrimp and commercial shrimp Specifications, especially how to obtain high yield and high efficiency under high-density farming conditions has become an important subject of urgent research in my country's freshwater shrimp farming industry

Under high-density breeding conditions, insufficient bait quantity is the main restrictive factor affecting the size of commercial shrimp. However, the price of pellet feed currently fed is relatively high, and the amount of feed waste and production costs will also increase significantly when feeding a large number of feeds. Feeding or feeding cheap feed will cause slow growth and small size of freshwater shrimp due to insufficient intake of nutrients. Therefore, solving the contradiction between feed feeding and feed waste in the process of freshwater shrimp farming is a necessary prerequisite for high-yield and efficient farming. , and how to provide sufficient nutrition for high-density cultured freshwater shrimp is one of the unresolved technical problems

With the rise in the price of raw materials for artificial feed, the high production cost has made it difficult for farmers who rely on artificial feeding of pelleted feed for shrimp farming to fall into an unprofitable predicament, and the difficulty of increasing income is increasing year by year

Since the return rate of artificial feed fed by freshwater shrimp farming is low, which seriously restricts the improvement of its farming output and farming benefits, it is urgent to find new alternative feeds
