How long is the life span of carp?

Carp, commonly known as carp, carp, etc., are Jiqing fish that people in the north like to eat, which are distributed all over the country. They are better than the four major central and southern fish in salt and alkali tolerance. They are the representative species of cyprinid fishes. They usually inhabit the bottom of the water body covered with water plants in rivers, lakes, reservoirs and marshes, mainly feeding on benthos. Let's take a look at how long the life span of carp is.

How long is the life span of carp?

Carp live very long, can live for more than 100 years, there is a simple way to calculate the age of carp, each scale is like the cross section of a tree trunk, there are many circles from the center to the outside, sparse circles grow in summer, dense circles grow in winter, so just count, you will know that it has passed several years, and there are two pairs of tentacles that ordinary fish do not have. Some carp will turn golden when they grow up, maybe because of this, some people regard carp as a sacred thing.

What kind of food does carp eat

It is one of the four famous freshwater fish in China, but now it is difficult to identify the original species or wild species of the Yellow River carp.

2. Jian carp: Jian carp takes the offspring of the hybrid combination of purse red carp and Yuanjiang carp as the basic breeding group. it has been selected and bred through directional breeding for six generations. it has stable genetic characters, wide food appetite, strong stress resistance and fast growth, and is the main breeding object promoted by the Ministry of Agriculture. It can be cultured all over the country, with a slender body, orange-red tail and fins, golden and bright body color, and can be domesticated into good feeding habits of timing, fixed point and quantity, so it is easy to catch. The main culture of the pond has high yield and good benefit.

3. Xingguo Red Carp: Xingguo Red Carp originated in Jiangxi Province and was bred by artificial directional breeding for more than ten years. It has stable genetic characters, wide adaptability, strong stress resistance and high survival rate. It not only has the economic value of edible fish culture (the red rate can reach 86.6%), but also has the utilization value of heterosis, which can be cultured all over the country.

4. Feng carp: Feng carp is a hybrid of loose scale mirror carp (male parent) and Xingguo red carp (female parent). Its body shape is shorter, its back is taller, its whole scale is higher, its body color is bluish gray, its growth rate and disease resistance are better than its parents, and its seedlings and species rely on artificial breeding.
