How many years does it take for a 72-jin catfish to grow?

A 72-pound fish takes 4-5 years to grow.

Fish can grow 5-6 catties per year, and about 10 kg per year in artificial breeding. The growth rate is very fast in the early stage, and it usually takes 4-5 years in the wild. But the growth rate in the wild is much slower, and it may take more than ten years.

The water temperature in an environment of 16℃~30℃ is very suitable for fish growth and reproduction. Fish fry can reach 2~3 jin after one year, and can reach 30~40 jin after 4 years. It can be seen how fast the fish grow. However, behind their rapid growth is a "disaster" for other freshwater fish, because it also means that a large number of freshwater fish will be eaten by them.

How many years does it take for a fish to grow to 72 jin? A fish that weighs 72 jin needs at least eight years to grow, because it can only grow about ten jin a year at most, so it takes at least eight years to grow to 72 jin.

Generally speaking, the maturity period of fish is about 3-4 years, but this depends on factors such as the breeding environment, feed and breeding technology. If the fish is cared for by a good breeding environment and nutritious feed, it can reach a weight of 72 catties in about 2-3 years.

Is it better to eat big or small catfish?

Small.

The body of a large fish is too big and the meat is too old. It is more delicious to pickle the spine or make it into smoked fish. The fish head is relatively delicious. The meat of a small fish is tender, so overall, smaller fish tastes better.

The fish belongs to the Cyprinidae family, class Pisces, with a head like a grass carp but a big mouth, cheeks like a catfish but yellow in color, a flat belly, and scales like trout but slightly thinner. It has a ferocious temperament and can prey on other fish.
