Key Points for Selecting Frog Fry and Scientific Breeding and Stocking Techniques

Frogs are not only guardians of the rice fields but also a nutritious delicacy on the human dining table. They are rich in protein, carbohydrates, water and a small amount of fat, and their meat is delicious. To meet market demand, there are now frog species bred specifically for food, including not only frogs but also bullfrogs and other varieties. But for breeding beginners, seedlings introduction is often very, and this also directly relates to the success of the breeding business. So how should frog fry be selected? And how should they be scientifically bred and stocked? Let's find out together.

How should frog fry be selected?

When beginners select frog fry, they must first check whether there are breeding frogs on the site, and when buying fry it is best to buy egg masses, which are not only convenient to transport but also ensure a reliable survival rate. When selecting egg masses, try to choose ones with about 2000 eggs or more per mass, and especially be careful not to buy egg masses produced by breeding frogs from farms with disease outbreaks. In addition, if buying tadpoles, be sure to choose the smallest ones once they have rounded heads, and the tadpoles are best from egg masses laid around April 15. According to most people's experience, the later the fry, the slower they grow and the smaller they are. Later tadpoles may even become zombie fry, so it is best to use tadpoles hatched from the first batch of egg masses.

How to scientifically breed and stock?

1. Frog pond construction

Generally, earthen ponds are used for breeding, with low investment and simple technology, making them very suitable for wide promotion and application by farmers. The frog farm requires an adequate water source, independent and convenient drainage and irrigation, and either shallow ponds or pits or a single idle field will do, with no limit on area size, and a surrounding barrier to prevent escape. At the same time, on the banks around the frog pond, shade sheds must be set up with bamboo, wood and asbestos tiles, with a shed height of 30-50 cm, leaving a distance of 1 m between two shade sheds to facilitate ventilation.

2. Stocking

Stocking is generally completed from early April to early June. Before stocking, apply 15 kg of quicklime per 100 sq m and spread it for disinfection, and after 5 days water can be added and frogs stocked. Stocking density depends on pond conditions; generally, if the pond facilities are good, the water source is adequate and food is guaranteed, 40-50 frog fry can be stocked per sq m.

3. Feed feeding

For frog farming in earthen ponds, feed sources can be developed through multiple channels, such as planting flowers and grasses around the pond to attract insects, hanging black light lamps to lure and gather mosquitoes, and manually catching locusts and miscellaneous fish, and culturing earthwormsfly maggots and other live small animals for feeding, so as to supplement the food supply and reduce the breeding technology requirements.

4. Daily management

Change the water frequently to keep the water quality fresh; strengthen escape prevention and harm prevention work; feed scientifically, and actively do a good job in pond cleaning, regularly disinfecting with quicklime, bleaching powder, potassium permanganate and other drugs; strengthen cold prevention and heat prevention work; in daily management, patrol the pond frequently and observe more. If abnormalities are found in the frogs' body color, behavior or feeding, handle them promptly.

The above is an introduction to the selection of frog fry and breeding and stocking, and we hope it is helpful to everyone. Finally, a reminder that you must choose suitable frog fry varieties for stocking according to the actual local market demand.
