Shelling interphase crawfish feed and preparation method thereof

Abstract

The invention provides a shelling interphase crawfish feed. The shelling interphase crawfish feed is prepared from the following components: corn flour, sorghum flour, wheat middling, peanut powder, shell powder, algae powder, fish meal, calcium hydrogen phosphate, compound vitamin, mineral composites and a core additive, wherein the core additive is prepared from the following components: houttuynia cordata, astragalus root, eucalyptus robusta, radix achyranthis bidentatae, selfheal, garlic, green tea and licorice. The feed can provide basic nutrients for crayfishes in shelling interphase, the algae powder and the core additive are added in the feed to greatly reduce the mortality rate of the crawfishes, and the shelling interphase crawfish feed is high in security, wide in raw material source and low in price.

Description

technical field

[0001] The invention relates to a crayfish feed, in particular to a crayfish feed between shelling periods and a preparation method and application thereof. Background technique

[0002] Crayfish is a lobster-like crustacean that lives in fresh water. Its scientific name is Procambarus clarkii, also known as red crayfish or freshwater crayfish. Procambarus clarkii is the most widely distributed invasive alien species among crustaceans. Procambarus clarkii forms an absolute competitive advantage in the local ecological environment because of its omnivorous, fast growth and strong adaptability. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarce. Procambarus clarkii has become an important economically farmed species in China in recent years.

[0003] The growth cycle of crayfish is relatively short. It only takes about half a year for a crayfish to go from giving birth, hatching...
