Abstract

The invention discloses a culture medium for benthic bait organisms for river crab culture. The culture medium comprises the following raw materials in parts by weight: 20-30 parts of manure, 10-15 parts of bran, 5-10 parts of soybean meal, 10-15 parts of zeolite powder, 10-15 parts of modified shaddock peel residues, 5-10 parts of seaweed residues and 0.5-1 part of an EM microbial agent. The invention further discloses a use method of the culture medium for the benthic bait organisms for river crab culture. The culture medium can provide sufficient nutrition for the benthic bait organisms, so that sufficient natural bait is provided for river crabs, the use of artificial feed is reduced, the cost is reduced, the substrate and water quality can be improved, and the yield of the river crabs is increased.

Description

technical field [0001] The invention relates to the technical field of crab cultivation, in particular to a culture medium for bottom dwelling bait organisms for river crab cultivation and a use method thereof. Background technique [0002] The bait is the material basis of river crab culture, and its type, quality and application rate have a very important and direct impact on the culture effect of river crab. The feeding habits of river crabs are mixed, and its bait includes two kinds of natural bait and artificial bait. Due to the high price of artificial feed, large-scale application will lead to a substantial increase in the cost of crab farming, which is not conducive to improving the economic benefits of crab farming. Therefore, using relatively low-cost natural baits to partially replace artificial feeds has become a way to reduce costs. Natural bait includes various organisms that river crabs like to eat naturally in water and on land, mainly plankton, aquatic pla...
