Frog farming techniques

Please introduce some basic techniques to raise frogs:

1. Breeding freely

a. Farming area

- Choose a quiet, meaty land, not too sour, too salty, light enough, have clean and active water sources.

- The pond bottom or the frog tank is sloping to the end of about 30, with the road leading to the water in and out, with sign or screen.

- Place for large frogs from 20-100m ² , shallow water, shore gently or have trenches or large trenches. Cover water hyacinth on half of the water surface.

- Place to keep tadpoles from 5-30m ² wide, 2-50 cm deep, sloping gently.

- The place where frogs are raised includes the water surface and pond edge. The water surface area is between 1/2 and 3/5 of the farming area, 2-20 cm deep, hard meat ground. Make about 20-30 caves for frogs, by lining bricks or using bamboo, wood, water hyacinth about 1/2 2/3 of the water. High fence 0.5m minimum.

- Where frogs are raised, there must be a pond or cement tank submerged with an area of ​​20-100m ² , from 0.8-1m deep. The fence is 1.2 meters taller. Plant trees around to create shade for frogs.

b. Techniques for laying frogs

- Choose good parent frogs.

- Pairing rate is 1 male 1.

- Stocking density: 1 pair / m ²

Male frogs often chirp before frogs lay 3-4 days. frogs lay eggs on the shore, in the middle of the weeds. Spherical frog eggs, 1.5-1.8 mm in diameter, including 2 parts in which the animal pole is the black part facing up. Frog eggs are joined together and floated on the water surface.

c. Egg hatching technique

- Avoid breaking the mucous membrane when picking eggs

- Use plastic or silk size of 90x50x25 (cm) to nurse 1-3 thousand eggs.

- 3-4 hours to replace clean water once, the temperature is lower than 33 ^o C.

- After 18-21 hours, at a temperature of 23-27 ^o C, frog eggs hatch into tadpoles. The first 2-3 days, tadpoles live on yolk on the abdomen, then can feed themselves.

d. Technique of tadpole farming

- Prepare pond: use lime with a dose of 2-3 kg / 100m ² to purify the pond, replace the new water and leave for 2-3 days to use. Best pond should have submerged and floating parts.

- Creating natural food is zooplankton, crustaceans in the first 10 days, by applying organic fertilizer at the dose of 0.2-0.3 kg / m2 into the pond 3-5 days before stocking.

- From 10-12 days of farming, flock and classify large and small to raise separately. When tadpoles have grown front legs, hind legs, stop feeding 2-3 days and release more water hyacinth.

e. Techniques for raising frogs

- Stocking density: 100-150 individuals / m ² , size from 2-5 g / head.

- Food: small earthworms, fish, shrimps, shrimps, crabs, food that are smaller than the width of frog mouths or synthetic pellets. Feed amount: 50-100g / 100 fish / day on 2 early morning and cool afternoon.

- After 1 month, the herd is kept separately.

f. Techniques for raising frogs meat

- With the frog size of 20-25 g / head, the stocking density is 40-60 heads / m ²

- Daily feed volume is about 3-5% of frog weight.

2. Techniques for raising cages or rearing in tanks

a. Cages are made of nylon net, fry net size, 1-1.2m high, 2m wide, 3-5m long. Tie the cage into the poles that plug in the pond, about 1.5 m away, so there is a pair of poles. Stretched all the way. The underside of the cage is close to the water surface, placing the foam between the bottom of the cage to allow frogs to rest and scatter food.

b. Water sources must be clean and free from pollution, and drop water hyacinths into separate plots. Regularly change clean water, replace water hyacinth twice a year.

c. Stocking

- Vietnamese frog breeds or imported frog breeds from Thailand and Malaysia
- Stocking density: 100 individuals / m ² , often separate herds of frogs, big and small.
- When the frog is big, gradually expand the farming density, from 70-80 individuals / m ² .

d. Feeding

- Using floating industrial pellets, sizes suitable for each frog size.
- Give frogs 2 meals a day, supplement protein by adding duck eggs, earthworms.

e. Take care of

- Keep the water source clean, regularly clean the cage, clean the pond. Citronella should be planted around the pond.
- Keep the environment quiet, pay attention to the sunshade for frogs.
- Every 3 days choose big frogs to separate and avoid eating each other.

3. Harvesting and transportation

- For seed frogs: Before seeding frogs, size 150-200 heads / kg for bathing with purple solution (5mg / 10 liters of water) about 5 minutes. Put the frog in a wet cloth bag with fresh water hyacinth. Place the bag in a vented foam box, and sometimes wet the bag.

- For meat frogs: Let meat frog stop eating before harvest 10-12 hours. Use a foam box with air vents and water hyacinth to transport or use a wet plastic bag.
