Abstract

The invention discloses a breeding method of selenium-rich crabs. Focusing on different growth periods of crabs, different artificial feeds are provided to feed the crabs, selenium-rich breeding is carried out in the aspects of the living environment and feeding of the crabs, the water quality is kept safe and free of pollution, the disease incidence is reduced, selenium-rich environment is created, and selenium-rich feed is provided, so that the selenium-rich crabs are produced. The artificial feeds are prepared from basic feed, microbial preparation, nano-selenium, minerals and vitamins.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to a selenium-enriched crab breeding method. Background technique [0002] Crabs are crustaceans of the suborder Brachycephala of the order Decapod, especially the species of the Brachycephalic family. It also includes some other types, such as about 4,700 species of crooked tails. Its distribution is found in all oceans, rivers and land. The crab's tail is different from other decapods, curling under the chest, and the carapace is usually broad. Usually moves by walking or crawling.
