Ecological bait for mixed culture of Exopalamon carincauda Holthuis and Portunus trituberculatus and preparation method thereof

Abstract

The invention relates to ecological feedstuff for the mixed culture of palaemon carincauda and portunus trituberculatus. The ecological feedstuff is characterized in that the ecological feedstuff is prepared by the following raw materials according to the weight percentage: 95 to 99 percent of basic nutrient content, and 1 to 5 percent of medicine content. The basic nutrient content comprises full cream fish meal, common Japanese mackerel powder, mussel cream, cuttle fish cream, shrimp head powder, canola meal, puffed corn, puffed soybean, peanut pulp, linter pulp, wheat middlings, and the like. The medicine content comprises vine of tuber fleece flower, linley eupatoium, forsythia fruit, rhubarb, asafetida, astragalus, albizia bark, liquorice, Indian bread with hostwood, choline chloride, active attapulgite clay, and the like. The invention also discloses a preparation method for the ecological feedstuff for the mixed culture of palaemon carincauda and portunus trituberculatus. The preparation method has balanced nutrient content, and is capable of meeting all the nutrient physiological requirements under the condition of the artificial mixed culture of palaemon carincauda and portunus trituberculatus, effectively reducing the mutual killing rate of palaemon carincauda and portunus trituberculatus, and improving the growth rate of palaemon carincauda and portunus trituberculatus.

Description

technical field

[0001] The invention relates to a breeding bait, in particular to an ecological bait suitable for the polyculture of white shrimp and portunus trituberculatus; the invention also relates to a preparation method of the ecological bait. Background technique

[0002] The mixed culture technology of white shrimp and portunus trituberculatus is to use the ecological complementarity of white shrimp and portunus trituberculatus to carry out polyculture, which increases the spatial stratification of the ecological structure of the cultured water body, reduces the cost of breeding, and improves the unit water body. production, thereby increasing the economic benefits of farming.

[0003] However, Portunus trituberculatus is ferocious by nature. During the mixed culture of Portunus trituberculatus and Portunus trituberculatus, it often occurs that Portunus trituberculatus preys on White shrimp. However, a large number of deaths occurred; white prawns and portunus trit...
