Black-spotted Frog Breeding Technical Manual: Help You Master Scientific Breeding Methods

AbstractSite selection for breeding black-spotted frogs: choose a place with abundant water and good water quality, with a reliable power supply. Build the black-spotted frog breeding pond: dig trenches and build ponds according to the terrain, lay a layer of black anti-seepage plastic film on the pond bottom, and set up a net above the pond. Create a natural ecological environment: hang several energy-saving lamps on both sides of the pond and plant some soybeans. Daily feeding and management of black-spotted frogs: feed bait such as yellow mealworms and fly maggots, and do not mix-culture black-spotted frogs caught from the wild without disinfection.

1. Site selection for breeding black-spotted frogs

1. Water quality requirements

When choosing a site, choose a place with abundant water and good water quality. Generally, the water quality can be tested. Black-spotted frogs are more suitable for living in weakly alkaline water (pH 7-8).

2. Power requirements

During the breeding process, there must be a reliable power supply to facilitate the daily management of black-spotted frogs.

3. Water conservancy requirements

Corresponding irrigation and drainage measures should be taken. Water intake should be convenient, and drainage should be smooth, which is helpful for drought resistance and waterlogging drainage.

4. Geographical location requirements

During this period, stay away from industrial areas and domestic pollution sources. It is not advisable to choose places where natural disasters occur frequently. If land needs to be leased for breeding, ensure the legality of the land to prevent land disputes.

2. Building the breeding pond for black-spotted frogs

1. Generally, use mu as the unit, then dig trenches and build ponds according to the specifications of 20 m long and 4.5 m wide (the size can depend on the terrain). The inner pond is 20 m long, 1.5 m wide, and 0.4 m deep.

2. A layer of black anti-seepage plastic film can be laid on the pond bottom, and soil should be used to compact both edges and the bottom. On both sides of the inner pond, a land area 1.5 m wide can be left for black-spotted frogs to perch and move around.

3. Then, above all the ponds, set up a net 2 m above the ground (allowing people to pass through freely) to prevent invasions by natural enemies such as egrets, ospreys, and sparrows. Water intake and drainage pipes need to be designed at the front and back of the pond to ensure smooth water intake and drainage during the breeding period.

3. Creating a natural ecological environment

To promote better growth of black-spotted frogs, a relatively closed simulated natural ecological environment needs to be created during the breeding period. Generally, several energy-saving lamps can be hung on both sides of the pond, and a small amount of soybeans can be planted. After black-spotted frogs change from tadpoles into young frogs, a few crucian carp fry can be raised in the pond.

4. Daily feeding and management of black-spotted frogs

1. Bait

(1) Because the eyes of black-spotted frogs are highly nearsighted, they can only see living things in front of them. Generally, bait such as yellow mealworms, earthworms, and fly maggots (the larvae of flies) can be fed.

(2) Considering breeding costs, fly maggots are a relatively good choice. Fly maggots contain protein and amino acids in their bodies, have comprehensive nutrition, and the maggots are also very active. Their palatability is relatively good, making it easy for black-spotted frogs to discover and eat them. Raising fly maggots is easy to manage, and has low cost, a short cycle, and high yield.

2. Preventing escape

The enclosure net outside the breeding pond is mainly to prevent black-spotted frogs from escaping. Black-spotted frogs are difficult to tame and good at jumping, so frequently check whether the enclosure net has holes or small openings. If there are any, sew and block them promptly.

3. Disease prevention and control

(1) Black-spotted frogs are a kind of wild animal and also have relatively strong vitality, so major infectious diseases generally do not occur. However, when the water source is unclean or wild black-spotted frogs are mixed in without disinfection treatment, skin rot disease is likely to occur.

(2) If local infection generally occurs, promptly remove the sick frogs and isolate them. During this period, penicillin sodium solution can be used and injected into the white skin area of the thigh.
