Fast-growing high-quality breeding method for young bullfrogs

Abstract

The invention discloses a fast-growing high-quality breeding method for young bullfrogs. The method comprises the following steps of 1, construction of a young frog pool and planting of aquatic plants; 2, hatching and management of frog spawns; 3, stocking of young frogs and feeding and management of feed; 4, separated breeding of the young frogs and fishing of adult frogs out of the pool. By means of the method, low-frequency ultrasonic waves are adopted for treating the frog spawns, the activity of the frog spawns is activated, the hatching time of the frog spawns is shortened, and the success rate of hatching the frog spawns is increased; through the addition of bullfrog tadpole strengthening liquid, bullfrog tadpoles obtain healthy and sufficient nutrients in the early stage, and a good foundation is laid for the growth and development of the young bullfrogs; by feeding the young bullfrogs with feed suitable for different growth stages of the young bullfrogs, the nutrition functionof all components in the feed is full achieved, the young frogs are acclimated to eat the static feed, and the feeding cost is reduced; by planting eichhornia crassipes with water purification and shading functions, the water environment is purified, the diseased rate of the young bullfrogs is reduced, and the yield of the bullfrogs is increased from various aspects.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a fast-growing and high-quality breeding method for young bullfrogs. Background technique [0002] Bullfrog ( Rana catesbiana ) belongs to Amphibians, Anura, and Ranaidae, a kind of amphibious animal. It is named for its male voice like a cow. It is the most famous large edible frog in the world. Because bullfrogs are native to North America and Mexico, they are also known as American water frogs. They are large, fast-growing, and high-yielding. At present, they have spread to all continents of the world; China's bullfrog breeding areas are mainly distributed in Guangdong, Fujian, Zhejiang, Jiangxi, Hainan, Anhui, Jiangsu, Hunan, Hubei, Sichuan and other provinces are the main cultured species of edible frogs in various places. Because of its high economic value, bullfrogs have been loved by consumers since they were first introduced into my country in the late 1950s. Bullfrog meat ...

Problems solved by technology

Ultrasonic radiation of different frequencies will have a certain impact on the digestibility of fish and shrimp seedlings. This may be due to the fact that low-frequency ultrasonic radiation will change the conformation of some digestive enzymes in fish and shrimp to change their catalytic activity, thereby changing the relationship between enzyme molecules and substrates. combined degree to affect the digestion of fish and shrimp seedlings; but there are few public reports on the impact of ultrasound on bullfrog breeding
