Feed for procambarus clarkii and preparation method thereof

Abstract

The present invention belongs to the field of aquaculture and discloses a feed for procambarus clarkii and a preparation method thereof. The feed is prepared from the following raw materials: full-skimmed steam fish meal, fermented rapeseed meal, peanut cake, wheat, fly maggots, high-gluten flour, phospholipid oil, fish oil, palm oil, oyster shell flour, mannan oligosaccharide, a shrimp premix, methionine and compound probiotics. The feed contains the fermented rapeseed meal and compound probiotics, does not contain antibiotics, reduces pollution of aquaculture water body of the procambarus clarkii, and is good in food attractant, better in feeding speed than the control group, fast in growth speed, strong in disease resistance, low in mortality, and finally high in yield and an ecologicaltype feed for the procambarus clarkii with good application prospects.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a crayfish feed and a preparation method thereof. Background technique [0002] The artificial breeding of crayfish in my country began in the 1990s. With the deepening of research, the current methods of crayfish farming in my country are diversified and the scale of farming is constantly expanding. The current scale of farming and processing ranks first in the world. The rapid development of crayfish farming has promoted the demand for crayfish artificial compound feed, and the research on crayfish feed has attracted more and more attention from the industry. Therefore, crayfish feed has become a decisive factor that potentially limits the development of crayfish farming. [0003] The formula of the aquatic feed in the prior art is too simple, the nutritional structure is not reasonable enough, the production process is also too simple, and the produced pellets...

Therefore, crayfish feed has become a decisive factor that potentially limits the development of crayfish farming

[0003] The formula of the aquatic feed in the prior art is too simple, the nutritional structure is not reasonable enough, the production process is also too simple, and the produced pellets cannot meet the requirements of stability in water

At present, although the high-temperature granulation and post-aging processes have been adopted to improve the water stability of the feed, it will have certain adverse effects on the sensory and food-attractive properties of the feed.
