Embodiment 1

[0023] Follow these steps:

[0024] 1. Species selection: Collect and breed tiger frogs that have been disease-free and strong for 2 years, weighing 250 grams for female frogs and 200 grams for male frogs, and place them in a moisturizing pool with a constant temperature of 20 degrees Celsius for breeding;

[0025] 2. Oviposition: Put 10 female frogs and 10 male frogs into the pond to mate and lay eggs;

[0026] 3. Tadpole cultivation: add 100 tablets of oxytetracycline and dry yeast to water for disinfection 5 days in advance. The hatched tadpoles are put into net cages at 600 / square meter and fed with tadpole powder for 10 days; at 300 / square meter cages, continue to be fed with tadpole powder for 1 month;

[0027] 4. Raising adult frogs: Adult frogs are raised in net cages at a density of 15 / square meter. After the tadpoles metamorphosis, they start to feed the frogs, and they can be sold when they are raised to 0.25 kg each. Described net cage is 6 meters long, 3 meters...

Embodiment 2

[0033] Follow these steps:

[0034] 1. Species selection: Collect and breed American bullfrogs that have been disease-free and strong for 3 years. The female frogs weigh 470 grams and the male frogs 400 grams as seed frogs. They are raised in a moisturizing pool with a constant temperature of 25 degrees Celsius;

[0035] 2. Oviposition: Put 10 female frogs and 5 male frogs into the pond to mate and lay eggs;

[0036] 3. Tadpole cultivation: add 100 tablets of oxytetracycline and dry yeast to water for disinfection 7 days in advance. The hatched tadpoles were raised in cages at 300 per square meter, and fed with tadpole powder for 7 days; at 150 per square meter, the cages were changed and continued to be fed with tadpole powder for 1 month;

[0037] 4. Raising adult frogs: Adult frogs are raised in net cages at a density of 5 / square meter. After the tadpoles metamorphosis, they start to feed the frogs, and they can be slaughtered when they are raised to 0.5 kg each. Polyure...

Embodiment 3

[0043] Follow these steps:

[0044] 1. Species selection: Collect and breed tiger frogs that have been disease-free and strong for 5 years. The female frogs weigh 230 grams and the male frogs 220 grams as seed frogs. They are raised in a moisturizing pool with a constant temperature of 30 degrees Celsius;

[0045] 2. Oviposition: Put 5 female frogs and 5 male frogs into the pond to mate and lay eggs;

[0046] 3. Tadpole cultivation: add 100 tablets of oxytetracycline and dry yeast to water 10 days in advance for disinfection. The hatched tadpoles are raised in cages at a rate of 500 per square meter, and fed with tadpole powder for 7 days; at 250 per square meter, the cage is changed and the tadpole powder is fed for 1 month;

[0047]4. Raising adult frogs: Adult frogs are raised in net cages at a density of 10 / square meter. After the tadpoles metamorphosis, they start to feed the frogs, and they can be sold when they are raised to 0.25 kg each.

Abstract

The invention discloses a method for cage culture of frogs, particularly a method for artificially breeding frogs in a sealed pond, which is disinfected at fixed period, by utilizing cages. The method comprises the steps of selecting parent frogs, spawning, cultivating tadpoles, and breeding young and adult frogs, and is characterized by comprising the steps of: (1) selecting parent frogs: selecting healthy and strong parent frogs which are cultivated for 2-5 years, and breeding in a 20-30 DEG C constant-temperature humidity-retention water tank; (2) spawning: placing male and female frogs in the tank at a ratio of 1:(0.5-1), mating, spawning, and transferring out the parent frogs after spawning; (3) cultivating tadpoles: breeding incubated tadpoles in small-pore cages in the pond, and feeding with tadpole powder until the tadpole tails break; and (4) breeding adult frogs: transferring the tadpoles of which the tails break to the cages in which foam boards and wood board are placed, feeding with frog feed, and harvesting until each frog is 0.25-0.5kg. The method has the advantages that the operation is simple and convenient, the water pollution is reduced, the survival rate of the frogs is improved, the insect pests are effectively removed and microorganisms are not destroyed, and the water, manpower and expense are saved.

Description

technical field [0001] The invention relates to a method for raising frogs, in particular to a method for artificially raising frogs in net cages. Background technique [0002] Frog, also known as frog, has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxifying, reducing swelling and relieving pain. At the same time, frogs prey on pests and are known as "farmland guards". With the development of ecological agriculture and green food industry, people have more and more demand for frog products, and artificial reproduction methods have begun to produce frogs in large quantities, as disclosed in Chinese patent 200510021230.7 A captive breeding method for artificial breeding of frogs is introduced. It introduces frog species selection, oviposition, hatching, tadpole cultivation, young and adult frog rearing, egg masses are placed in hatching cages placed in water, and natural hatching is carried out in micro-flow wate...
