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

Abstract

The invention relates to a bentonic bait organism culture medium for river crab cultivation and a use method thereof. The use method comprises the following steps of: crushing soybean meal, maize, cellulose and vinasse, and uniformly mixing the raw materials with bran, rice bran, humic acid, attapulgite, fluorspar powder, biological organic fertilizers and organic matter to prepare a culture medium for river crab cultivation to culture bentonic bait organisms and water weeds. The prepared bait organisms can replace more than 50% of artificial feeds, so that the cultivation cost is greatly lowered. Meanwhile, high-quality bentonic bait organisms can provide a nutrition source for quick growth of river crabs, so that the cultivation scale, yield and benefits can be greatly improved. The produced high-quality aquatic product can increase the market competitiveness and reduce the cultivation risk.

Description

technical field [0001] The invention relates to a benthic bait biological culture medium for river crab cultivation and its use method, in particular to a method for cultivating benthic bait organisms and aquatic plants such as water worms, snails and shellfish by using the medium put in the bottom mud to cultivate river crabs. The method of breeding. 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. The main sources of feed for river crab farming in China are: ① Artificially feeding anim...
