Staged feeding and female mutagenesis multifunctional feed of rana tadpole for reducing water body pollution

Abstract

The invention relates to a staged feeding and female mutagenesis multifunctional feed of rana tadpole for reducing water body pollution. The feed is characterized in that: according to an adopted technical formula, the feed consists of a main material and auxiliary materials; and formulas of per kilogram of feed at different stages are different. The feed has the advantages that: a produced tadpole bait is in a frozen state at normal temperature, and is difficult to dissolve in water when fed; bait waste is reduced; the pollution of bait residues to a water body of a culture pond is avoided; the feed is similar to rana egg jelly and has prominent palatability; nutrients are proportioned according to different growth stages, and the feed has comprehensive and rich nutrition; the feed has obvious effects of preventing, controlling and treating the common diseases of the tadpole when a Chinese herbal medicine compound preparation for preventing the diseases of the tadpole is added, does not have toxic or side effect or form residues in the body of the tadpole after being used, and prevents germs from medicament resistance and medicament tolerance; when a rana tadpole gender inducer is added into the feed according to a scientific proportion, malformed frogs are avoided while the proportion of female frogs is greatly improved; the bait waste caused by dissolution and sedimentation of the feed is reduced; accurate control over the feeding amount of the feed is realized; and the culturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a multifunctional feed for segmental feeding of Rana tadpoles and female mutagenesis for reducing water body pollution. Background technique [0002] In the past, most Rana tadpoles were fed with cornmeal, grass, vegetables, and animal scraps. The nutritional ratio was not comprehensive, or the bait was unhygienic, which led to serious diseases of the tadpoles and a low survival rate; It has been improved, but it will decompose and settle in the water soon after being put in. The feed tadpoles sinking into the bottom of the breeding pond are not easy to eat. While causing feed waste, it will seriously pollute the breeding water body. If the water is not changed in time, it is easy to cause tadpoles in batches die. Contents of the invention [0003] In order to solve the above problems, the present invention provides a Rana tadpole subsection feeding and female mutagenesis multifunctional feed that reduces water pollution.
