Problems solved by technology

[0005] At present, the conventional method of cultivating river crabs comprises the following steps: 1) select crab seedlings; 2) pond water quality treatment; 3) release seedlings; 4) feeding management: directly put in animality, such as baits such as snail meat and fish meat; Animal bait is used at each stage. Although animal bait can accelerate the growth of crabs, it will produce a lot of parasites and bacteria, resulting in low survival rate and poor quality of crabs.

Abstract

The invention provides an ecological aquaculture method for river crabs. The method comprises the following steps: (1) building of a pond; (2) selection of juvenile crabs; (3) treatment of water quality; (4) putting of the juvenile crabs in the pond; (5) water adding and replacement treatment; (6) bait feeding management. During bait feeding management, a traditional Chinese medicine additive is intermittently added in a first stage according to growing characteristics of the crabs, so that on the one hand, the phenomenon that the crabs cannot adapt to the traditional Chinese medicine additive at the very start can be prevented, and the traditional Chinese medicine additive can kill pests and resist bacteria; furthermore, the traditional Chinese medicine additive in the first stage and a second stage can resist germs and viruses, and can enhance the immune function, so that various diseases caused in the period of baby crabs are prevented, and the survival rate is increased; in the second stage and a third stage, a traditional Chinese medicine additive different from the traditional Chinese medicine additive in the first and second stages is adopted, so that on the one hand, pathogenic bacteria and funguses can be prevented according to the growing stage of the crabs, and on the other hand, the added traditional Chinese medicine additive improves the water quality for the crabs and increases the freshness.

Description

[0001] 【Technical field】 [0002] The invention relates to a breeding method, in particular to an ecological breeding 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 treatm...
