CATDOLL : CATDOLL: Can black carp, grass carp, crucian carp and flat carp be raised together?

Can black carp, grass carp, crucian carp and flat carp be raised together?

Black carp, grass carp and crucian carp can be raised together. Black carp eats snails and grass carp eats aquatic plants. The two fish have no conflicting feeding habits. If the water contains enough oxygen, silver carp that eats phytoplankton and bighead carp that eats zooplankton can also be raised together to regulate the water quality. Since ancient times, China has raised black carp, grass carp, silver carp and bighead carp in the same pond, collectively known as the four major carps.

Crucian carp is omnivorous, and its diet is similar to that of grass carp and black carp. However, crucian carp is small in size and cannot compete with the large black carp and grass carp for food. However, crucian carp can pick up the crumbs and residues left after black carp and grass carp eat, so they can be raised together.

Flat fish, such as Song Shuguo, refers to the marine silver pomfret, so they cannot be raised together. The first three are freshwater fish and are not suitable for saltwater, and silver pomfret cannot live in fresh water.

If the flat fish refers to bream, then its diet is similar to that of grass carp, but bream is a medium-sized freshwater fish, which cannot compete with grass carp and will suppress crucian carp. If you raise bream, do not raise grass carp and crucian carp in the same pond.

How many grass carps can be raised in one acre of fish pond?

How many grass carps can be raised per acre depends on the amount of feed and seedlings put in. Under normal circumstances, it is normal for commercial fish to produce about 1,500-2,000 catties per acre, and it is common for seedlings to produce about 700-800 catties per acre.
