Experience in raising copper frogs

1. About frog breeds:

At present, farmers in many localities in the whole country are mainly copper frogs (domestic frogs), some of them

This frog, highly adapted to the climate conditions of our country, has a healthy life, is less prone to diseases, easy to raise, accepted by the domestic and foreign markets. Mature frogs after 5-6 months of breeding have an average weight of 100-120g / fish.

2. Technical care and nurturing:

Conditions for breeding frogs are gardens or ponds with an area> 50m ² ; having clean water sources, proactively supplying and escaping; building a brick wall 1.5-1.7m high, enclosed around, preventing frogs from jumping out; making artificial caves for frogs to shelter; Plant trees around frogs to create shade for frogs to stay in the sun. If frogs are raised by ponds, then drop water hyacinth or grow spinach 2/3 of the water surface. In the garden, there is a lot of light in the evening and a lot of flowers are planted (attracting insects of the day, the light-headed insects fly to the evening as a supplement for frogs).

Frog sex discrimination is as follows, male frogs have two black dots in the lower jaw, the two sides almost. The front foot is more rough, the forefoot has horny flesh. Gray skin, not smooth like females, male frogs are usually smaller than female frogs if they are the same age, with a feeding regime.

Female frogs do not have the characteristics of male frogs, until the season of breeding frogs with big, softer bellies than male frogs.

Stocking density : Young frogs, weighing 5-10g / head: 40-60 individuals / m ² . After each month of age, frogs gain weight quickly, raising area needs to expand, gradually increase. When harvested, the area is 3-4 times larger than the initial stocking area.

Food for frogs : Supplementing many animal proteins such as fresh fish, dried fish, shrimp, crab, snails, high protein concentrate bran, . Guaranteed: 20% meat, fish + 80% cereal flour in the diet eat + B.complex (0.2%). These foods are cooked into a solid powder, extruded through a manual processing machine or an electric motor into pellets, or fibers.

Frogs in the wild often eat animated food (animal food that lives and runs). Want frog to eat static food (processed food) need to persistently forging frog gradually gradually in 5-7 days. The amount of feed for frogs is 8-10% of frog weight. Day for frogs to eat 2 times in the morning and afternoon. Feed frogs on the floor, wooden panels or corrugated iron to float on water or on land. Clean feeding utensils before feeding.

In the evening, light the lamp for 18-21 hours, to attract the directional insects to feed the frog.

Every day to monitor the growth of frogs, healthy frogs quickly and vivacious. When frogs are often slow, eat less or do not eat, need timely treatment.

Before harvesting, frogs should be fattened for 30 days. This time for frogs to eat protein-rich diets of 30% fish meat + 70% cereal feed + 0.2% B.Complex.

3. Preventing and treating some frog diseases:

Prevention : When the nurturing environment is polluted by dirty water, leftover rotten food, . First, frogs get skin diseases, then get infected, frogs get bloated or skin sores, Do not eat, after a few days will die.

Change water regularly (5-7 days / time) clean for frogs. Sanitize the whole frog breeding area after harvest and before stocking frogs with new disinfectants such as Virkon; Oxidan-tca; Han-Iodine; Benkocid . These drugs need to be rotated when used to avoid the germs of bacteria.

Eliminate dead animals from the farming area. Avoid noises, loud noises, suddenly make frogs eat poorly and gradually become ill.

Prevent frogs and snakes from harming frogs.

Treatment of some common diseases :

Bloating disease : the symptoms of frog abdomen swell, pale skin, eat less, then do not eat and die when infected 5-7 days. Treatment, new water changes. Mix Penicillin with 1-2 million units / 5 liters of clean water, bathe for 2-3kg frogs / time / day (for frogs to soak for 30 minutes).

Bowel disease : When suffering from anal disease, the frog is red, gently squeezing the red blood flow. Stool live, white. Treat a small crushed Ganidan tablet mixed with food for 3-5kg of frogs per day.

Bacterial red spot disease : The disease often has signs in the thigh, initially the lesion is small like a pin, after a few days of sores.

Treatment: Change the water in the culture area, use copper sulfate (green alum) mixed with 5% concentration sprayed throughout the garden and bathe the frog 10-15 minutes in the sulphate water with concentration of 0.5-0.7%.

Wheel infection : The initial symptoms of frog skin secrete a lot of mucus, creating silvery white spots, then the lesions spread, frogs eat poorly and die after 7-10 days of infection. Diseases of the wheel often suffer from hot weather.

Cure: Replace new water, use CuSO ₄ (copper sulfate) concentration of 0.5-0.7% or 2-3% saline, bathe frog for 10-15 minutes.

4. Harvest:

After raising for 5-6 months, when the frog reaches 100-120g / head, harvest, bring wholesale, wholesale to customers.
