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

Effect test

Embodiment 1

[0026] In order to verify the beneficial effects of the present invention, in February 2016, the researchers did relevant verification tests of the present invention in Dongxin Farm, Jiangsu Province, and measured their relevant indicators after the bullfrogs came out of the pond. The obtained results are shown in Tables 3 and 4; specific methods as follows:

[0027]1. Construction of young frog ponds and planting of aquatic plants: from late February to early March, the selected area is 50m 2 Build a young frog pond in the pond, the slope of the pond is 1:2.5, the water and land area is 1.5:1, the pond depth is 1.0m, and a 1.35m high anti-escape net is set around the earthen pond; the plump and yellow-brown water hyacinth seeds are sown In the water of young frog ponds, the amount of sowing is based on ensuring that the area of ​​water hyacinth after growing up accounts for 40-60% of the entire water surface area, and then the water hyacinth is routinely managed;

[0028] 2....

Embodiment 2

[0032] In order to verify the beneficial effect of ultrasonic treatment of bullfrog ovum in the route of the present invention, researchers do relevant comparative verification tests in the laboratory, and the specific methods are as follows:

[0033] The present invention: adopt the method step in the embodiment 1, process 150 frog eggs with ultrasonic wave, count hatch success rate and tadpole health degree after it hatches, the result is as table 1;

[0034] Contrast: 150 fertilized eggs from the same source were directly put into the hatching pond for hatching, and the hatching rate and tadpole status were counted. The results are shown in Table 1.

[0035]

[0036] From Table 1, we can see that after ultrasonic treatment of frog eggs, the hatching rate of frog eggs has been greatly improved compared with direct hatching, and the body color of hatched tadpole seedlings is darker, shiny, lively and active. The ability to eat and swim is strong, so that the young bullfrog...

Embodiment 3

[0038] In order to verify the beneficial effect of the bullfrog tadpole strong liquid in the route of the present invention, the researchers did relevant comparative verification tests in the laboratory, and the specific methods are as follows:

[0039] The present invention handles: adopt identical bullfrog tadpole strong liquid among the embodiment 1, raise 150 tadpoles just hatched to its complete metamorphosis in the hatching tank, count the young frog survival rate, average weight and health degree, the result is as table 2;

[0040] Conventional comparison: Using conventional breeding methods, 150 tadpoles hatched in the same batch were raised in the hatching tank until they were fully metamorphosed, and the survival rate, average weight and health of young frogs were counted. The results are shown in Table 2.

[0041]

[0042] It can be seen from Table 2 that the survival rate and average weight of the juvenile frogs treated with the bullfrog tadpole strong liquid are...

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 ...
