Benthic food biological medium for river crab culture

Abstract

The invention discloses a benthic food biological medium for river crab culture. The biological medium comprises raw materials as follows: chicken manure, wheat bran, rapeseed cakes, rice bran, rapeseed meal, soybean meal, straw, kelp powder, pumpkin powder, snail meat powder, tenebrio molitor powder, garlic powder, bone meal, trash fish meal, egg yolk lecithin, soyabean lecithin, sawdust, calcium superphosphate, potassium chloride, zinc sulfate, magnesium sulfate, ammonium humate, ammonium dihydrogen phosphate, urea, manganese sulfate, monopotassium phosphate, egg shells, coal, borax, sepiolite powder, attapulgite, peat soil and a biological fermentation agent. The invention further discloses a preparation method of the benthic food biological medium for river crab culture. The medium can effectively increase the yield of benthic food organisms and improve the quality of the benthic food organisms and contains rich nutrients for growth of aquatic plants.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a benthic bait biological culture medium for river crab cultivation. Background technique [0002] River crab culture usually adopts methods such as pond culture, paddy field culture, river ditch culture, lake culture and reservoir culture. These culture methods all need to be fed with a large amount of artificial feed to obtain better returns. Since the price of feed has risen sharply in recent years, the cost of breeding has increased significantly, and the loss of breeding has continued to expand. Therefore, it is very urgent to find a new method that can replace artificial feed for river crab farming. With the increase in the price of raw materials for artificial feed, the increase in production costs, and the decline in the sales price of river crabs, the benefits of relying on artificial feed for crab farming are declining year by year, and it is increasingly difficult for farmer...

AI Technical Summary

Problems solved by technology

At the same time, due to the poor foraging ability of river crabs and the low utilization rate of artificial feed, the nutritional diseases caused by this are increasing day by day, which can eventually be manifested as low breeding output, high breeding costs, and the size of commercial crabs grown. Small and poor quality, difficult to improve breeding efficiency
