CATDOLL : CATDOLL: What book should I buy for the breeding techniques of grass carp, silver carp, crucian carp and bighead carp?

1. What book should I buy for the breeding techniques of grass carp, silver carp, crucian carp and bighead carp?

It depends on your water source conditions and what you mainly breed. Below is an example of grass carp breeding. The amount per mu is 1,200 grass carps, 300 black carps, 200 silver carps, 50 bighead carps, 1,000 crucian carps, and mandarin fish. Mandarin fish has a high oxygen requirement, so it is recommended to breed it alone and not mix it with these fish. Sichuan Zhuyuan Aquatic Products hopes to help you.

2. Why do black carp, grass carp and bighead carp die in mixed fish ponds?

If there is no obvious ulcer on the dead fish, it means that it is hot today and the water is lacking oxygen. Use an aerator to increase oxygen in the morning and evening!

3. Why do only grass carp and black carp die from time to time in a mixed fish pond? Can someone please give me some advice?

The water surface is not clean. Lack of oxygen.

4. I want to do a large-scale mixed breeding. Can I raise black fish, soft-shelled turtle, carp, black carp, crucian carp and grass carp together?

Brother:

To be precise, it is not allowed. If you get sick, it will be difficult to treat. Grass carp medicine cannot be used on turtles. Black fish medicine cannot be used on carp. Do you think it is okay?]\

The above answers seem to be true and scientific. Please accept them. It is not easy to do so, so cherish it.
