After one year of breeding practice, it shows that the frogs are cultivated in cold and low yield fields in mountainous areas of northern Fujian. The water body is warm in winter and cool in summer. The frog is suitable for long growth period and short dormancy period. Its benefit is more than 100 times that of rice. 2300 kilograms, profit 25,300 yuan a mu. The farming techniques are as follows: First, the cultivation of tadpoles technology (A) Clear ponds and basal fertilizer: 1 clear pond: pond should be 30-40 cm deep, with an area of 10-50 square meters. 7-10 days before tadpole stocking clear ponds, commonly used drugs are quick lime and bleach. Tadpoles stocking before, with a mesh net pull network, remove the drug
