CATDOLL : CATDOLL: Which fish, silver carp or grass carp, has fewer bones?

1. Which fish, silver carp or grass carp, has fewer bones?

Grass carp has fewer bones and they are slightly thicker, while silver carp has more bones and they are thinner.

Silver carp! Actually, I think they are similar! It’s just that the spines of grass carp are relatively more concentrated, all small, densely packed, and some are hidden very deep, so you may get pricked if you are not careful.

2. What is the ratio of grass carp and silver carp in fish ponds?

The ratio of grass carp and silver carp in mixed culture should be 3:1 [Abstract]: "One grass carp with three silver carps" is a popular fishing proverb. However, from the perspective of scientific fish farming theory, the ratio of grass carp and silver carp in mixed culture should be determined according to the production conditions and the fish that are suitable for the main culture. If herbivorous fish are the main fish, then the ratio of "one grass carp with three silver carps" should not be adopted in the variety matching, but "three grass carps with one silver carp" is more scientific [Keywords]: Silver carp Grass carp Herbivorous fish Plankton supply and demand relationship Variety matching Organic matter Production conditions Scientific fish farming Silver carp [Classification number]: S964

3. Why do silver carp and grass carp raised in the same fish pond grow very fast while bighead carp grows very slowly?

There are too many silver carp and too many bighead carp, which leads to a lack of food for bighead carp. The general ratio of bighead carp to silver carp is 2:8.

Bighead carp, whether it is the main or supplementary fish,

The relationship with silver carp must be handled especially well. Because silver carp and bighead carp have similar feeding habits, silver carp is lively and agile, while bighead carp is slow and eats a lot. When competing for food with silver carp, they are at a disadvantage, often do not eat enough, and their growth is severely inhibited.

When stocking silver carp, the size is smaller than that of bighead carp in the same pond.

For intensive ponds with normal mixed culture of bighead carp as a supplement, one rule must be noted: the maximum number of bighead carp in the pond per mu is only about 40kg. The reason is that the bait biomass in a 1-mu mixed fish pond with silver carp is only enough to sustain the survival of 40kg bighead carp, and it is difficult to meet its growth requirements. Generally speaking, the bighead carp stock in a 1-mu mixed fish pond grows very fast within 25kg, and then it will grow slower and slower, and the group will almost stop growing when it reaches 40kg per mu.
