Bullfrog is a very delicious dish that many people like to eat. It has been selling well in the market, so more and more people are breeding it. What is the reasonable density of bullfrog breeding? ? How to carry out feeding and management? The editor will answer your questions below.

1. Reasonable Density for Bullfrog Breeding

Newly hatched tadpoles can be raised appropriately and closely for easy management. 2,000 to 3,000 tadpoles can be stocked per square meter.

After 10 days, as the individual grows up and its feeding ability increases, the density should be gradually reduced. Generally, 500-1,000 birds per square meter are stocked, and after 30 days until before metamorphosis, the stocking rate is 100-300 birds per square meter.

When stocking, soak with 3% salt for 5 minutes to disinfect and sterilize.

2. Bullfrog feeding and management

1. Tadpole management

(1) Tadpoles are the initial form of bullfrogs. When managing tadpoles, regular inspections must be done , observe the tadpoles’ activities and eating conditions, and then make records.

Control the temperature and depth of the breeding pond water, manage the water quality, and ensure the water quality is clean and clear.

(2) Do a good job in disease prevention of tadpoles.

Strengthen the management of feed, and take timely measures for abnormal tadpoles.

The most serious one is the floating head. The floating head represents insufficient or excessive dissolved oxygen. The dissolved oxygen content in the breeding pond should be adjusted in time.

2. Management of young frogs

(1) A small amount of meat can be fed during the young frog period, such as dried silkworm chrysalises and animal offal, but attention should be paid to the amount and not allowed to be added. Too much will cause the young frogs to be too full, which is not conducive to nutrient absorption and later digestion.

(2) For the growth of young frogs, temperature and humidity must be controlled, classification measures must be taken, and the prevention and control of natural enemies and diseases is the most important.

If you want to overwinter, its overwintering management is also the top priority.

3. Management of adult frogs

After reaching the adult stage, the bullfrog's growth ability is strengthened, it becomes more and more energetic, and its jumping ability is gradually improved.

So we must take anti-escape measures around the breeding pond and increase the height of the fence to prevent adult frogs from jumping out of the breeding pond.

The suitable temperature for the growth of adult frogs is about 25 degrees. Control the water temperature and do a good job of shading in summer to prevent direct sunlight from burning the skin of the bullfrog.

The time when adult frogs reach the spawning period has a lot to do with weather changes. They usually start laying eggs in the morning on sunny days with 22 degrees Celsius or above.

4. Parent frog management

(1) Parent frogs are frogs with strong growth ability selected as breeding seeds among adult frogs. Parent frogs are generally large in size and high in weight.

And the breeding and growth of parent frogs requires a huge amount of space, so the number of parent frogs per square meter should not exceed two during management.

(2) Breeding frogs requires a lot of nutrients. The daily food intake will exceed the body weight by at least 1/10, and the nutrition of the bait must be comprehensive.

Since parent frogs are used for spawning and reproduction, the growth environment of parent frogs must not only be suitable for the growth of parent frogs, but also ensure the smooth hatching of eggs. The water temperature is about 25 degrees, and the water level cannot exceed 35 cm. Increase Hatchability of frog eggs.

Okay, after reading the editor’s answer above, you all know what the reasonable density of bullfrog breeding is. The density of bullfrog breeding at each stage is different. In addition, the editor also gives you It talked about the feeding and management of its four growth stages. If you think it is good, hurry up and collect it!
