Freshwater shrimp culture medium

Abstract

The invention provides a freshwater shrimp culture medium which comprises the following formula in parts by weight: 15-25 parts of bean pulp, 10-20 parts of bean dregs, 15-25 parts of rice bran, 5-8 parts of sodium humate, 5-10 parts of attapulgite, 5-10 parts of fluorspar powder, 10-20 parts of cellulose, 40-60 parts of bio-organic fertilizer and 20-60 parts of organic matter. After the freshwater shrimp culture medium is used, mass propagation of tubificidae can be promoted, and aquatic plant biomass is promoted to be rapidly increased, so that freshwater shrimps can be fed, more than 50% of freshwater shrimp feed is replaced, and the cultivation cost is greatly lowered; furthermore, high-quality benthic bait organism can provide a nutrition source for the rapid growth of the freshwater shrimps, so that cultivation specification, yield and benefit are greatly improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a culture medium for freshwater shrimp. 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 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....

AI Technical Summary

Problems solved by technology

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
