How long does it take for black carp to grow to ten pounds?

The time required is different in different waters and different food. The growth rates of male and female fish are also different. The long-term water temperature, long-term water quality, etc. are all directly related to the growth of the fish. Under normal circumstances, 3 to 4-year-old herring can grow to 10 pounds.

1. Different water quality affects the growth of herring differently

In my hometown, there are many large lakes with clear and fertile water, and there are various kinds of fat and tender fish in the lakes. There are many aquatic plants, and there are countless snails, large and small river clams, etc. at the bottom of the water. It is a paradise for all kinds of freshwater fish and shrimps.

Herring grows in such water bodies. When it is young, it feeds on plankton, small fish, shrimps and molluscs. It grows very quickly and can reach or exceed 1 catty in one winter.

2. Different water temperatures have different effects on the growth of herring

Take our place as an example. It is located on the Yangtze River and has four distinct seasons. Most of the time, the water temperature exceeds 15 degrees, and the highest temperature The water depth will not exceed 35 degrees.

Generally, fish are suitable for living in water temperatures of 24 to 28 degrees. Both below 15 degrees and above 35 degrees are not suitable for fish growth. The water temperature in our lake area is suitable for fish in all seasons except late winter and early spring when fish grow slowly or stop growing.

Herring has a different characteristic from other fish, that is, herring likes to eat screws and small river clams.

In the throat of herring, below the occipital bone, a kind of keratinous hyperplasia stone can grow that helps crush hard food such as snails and river mussels. It is called herring stone, fish stone, fish pillow stone, etc.

Once the herring grows into this stone, it will grow very quickly because it can easily crush nutritious food such as snails. The fishermen here say: Green carp can grow 3 kilograms a year, and once the snail is bitten, it can grow 10 kilograms a year. Of course, this 10 kilograms is not an accurate number, but it is enough to show that once the herring can feed on snails, it will grow very quickly.
