Abstract

The invention provides a culture method for river crabs. The method comprises the following steps of 1, pond building; 2, juvenile crab selection; 3, water quality treatment, wherein 60 kg to 70 kg of mixture of 5%-15%quick lime and 85%-95% of traditional Chinese medicine mixed powder I is sprayed per mu of a nursery pond for disinfection 12-15 days before juvenile crab stocking, and 70 kg to 90 kg of mixture of 10%-25% of quick lime and 75%-90% of traditional Chinese medicine powder II formed by smashing 1-2 parts of garlic, 1-2 parts of folium artemisiae argyi, 0.1-0.3 part of semen cassia, 0.2-0.4 part of the root of kudzu vine and 0.1-0.3 part of folium apocyni veneti is taken for disinfection of per mu of a culture pond every other 10-15 days; 4, juvenile crab stocking; 5, bait feeding management. A large quantity of traditional Chinese medicine ingredients are added during water quality treatment, the disinfection and insect killing functions are achieved, nutrition is achieved, the advantages of being free of residues, small in toxic and side effect and free of pollution are achieved, the survival rate of the crabs is increased, and the quality of the crabs is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to a cultivation method, in particular to a cultivation method of river crabs. [0003] 【Background technique】 [0004] Crab meat contains a variety of vitamins, among which vitamin A is higher than other terrestrial and aquatic animals, vitamin B2 is 5-6 times higher than meat, 6-10 times higher than fish, and 2-3 times higher than eggs . The content of vitamin B1 and phosphorus is 6-10 times higher than that of ordinary fish. The edible part of hairy crab per 100 grams contains 17.5 grams of protein, 2.8 grams of fat, 182 milligrams of phosphorus, 126 milligrams of calcium, and 2.8 milligrams of iron. In addition to being rich in calcium, crab shells also contain crab red element, crab xanthin, etc. Therefore, river crabs are cultivated in large quantities. [0005] At present, the conventional method of cultivating river crabs comprises the following steps: 1) select crab seedlings; 2) pond water quality treatment; d...
