CATDOLL : CATDOLL: How big can wild crucian carp grow and in which water layer do they live?

answer

Wild crucian carp can usually grow to a maximum of about 1.5 catties, artificially cultivated crucian carp can grow to about 2 catties, and engineered crucian carp can grow to about 3-8 catties. When artificially cultivated crucian carp, the growth cycle is generally 6 months, that is, it is released in May and can be caught in December, at which time its weight can exceed 200 grams. The growth cycle of wild crucian carp is about 24 months. Wild crucian carp hatched in May and June can generally only grow to 20-30 grams in winter, and can only reach about 200 grams in the winter of the following year.

1. How big can wild crucian carp grow?

1. The weight of wild crucian carp

Generally speaking, wild crucian carp can grow to a maximum of about 1.5 kilograms, artificially farmed crucian carp can grow to a maximum of about 2 kilograms, and engineered crucian carp can grow to about 3-8 kilograms. The living environment of crucian carp will affect its weight.

2. Crucian carp growth rate

(1) The growth cycle of artificially farmed crucian carp is mostly about half a year. If it is released in May, its weight can reach more than 200 grams by December and can be caught and put on the market at this time.

(2) The growth cycle of wild crucian carp is mostly about 2 years, and the weight growth is relatively slow. If wild crucian carp is hatched in May or June, it can only grow to 20-30 grams in the winter of the same year, and can only grow to 100-150 grams in the summer of the following year, and can only grow to about 200 grams in the winter of the following year.

(3) If artificial breeding is to be carried out, fish fry can be released in mid-to-late April, with 10,000-25,000 fry per mu of pond. When the fry reach a certain size, an appropriate amount of silver carp can be released into the pond to regulate the water.

(4) During the breeding process, an appropriate amount of aquatic plants can be cultivated to provide natural bait for crucian carp. When feeding artificial feed, the protein content should be ensured to reach about 30%, otherwise it may be difficult to meet the nutritional needs of crucian carp.

2. In which water layer do wild crucian carp live?

1. Crucian carp usually lives at the bottom of the water, mainly distributed in reservoirs, ponds, rivers, lakes and other waters across my country. The most suitable water temperature for crucian carp is 15-25°C. It can eat when the water temperature is 0-30°C and is more active when the water temperature is 20°C.

2. Crucian carp has strong adaptability. In spring and autumn, they will move and forage in shallow waters with dense aquatic plants. In summer, they will live in deep waters and shady places. In winter, they will go to deep waters to avoid the cold.

3. The peak feeding season for crucian carp is spring, when they generally forage for food day and night. In summer, crucian carp forage in the morning, evening and night, in autumn they generally forage all day, and in winter they forage around noon.

4. Juvenile crucian carps like to eat fishy food, while adult crucian carps like to eat plant-based food, and will tend to be vegetarian when the weather turns warmer. If it is cold, crucian carps will also like to eat fishy food.
