Cultivation of Rana chensinensis in South China-- breeding preparation of Young Frog and Adult Frog

Breeding of young and adult frogs

1. The newly metamorphosed young frogs are cultured artificially under the fully closed condition of the purse seine, which is easy to manage, less land, fast growth rate and high survival rate, but the following three basic elements must be met to ensure the normal growth and development of young frogs.

(1) Disinfection and disinfection: before the young frogs enter the breeding ground, the breeding site must be fully disinfected. Before disinfection, double the site, every 666.7 square meters (mu) with trichlorfon or permethrin 100g water solution and spray, to kill underground pests and beetles; then use quicklime (block ash) 250kg, divided into several piles and then watered and powdered, can be evenly scattered to the site, or 13kg bleach dissolved and sprinkled. After entering the breeding ground, young frogs should also be disinfected regularly to kill germs and reduce the incidence of disease.

(2) Feed supply: it is necessary to provide sufficient, smaller, live bait that can be swallowed for young Chinese forest frogs. The 2nd instar Tenebrio Molitor and Nine Dragon insect (introduced from Japan, the maximum length of the larva is 1 cm long, which is better than that of Tenebrio Molitor) and aseptic fly maggots within 3 days.

(3) Ecological environment: provide a multi-layer green three-dimensional ecological environment and relatively humid climate for Rana chensinensis. Spray water into the breeding site regularly, do not let the strong light shine directly on the Chinese forest frog, and set up 2 or even 3 layers of sunshade net facilities above the breeding site if necessary.
