The maximum growth of wild crucian carp is about 1.5 kg, the maximum growth of cultured crucian carp is about 2 kg, and some engineering crucian carp can grow to about 3-8 kg. The breeding cycle of crucian carp is generally about 6 months, and it will grow rapidly when cultured artificially, and its weight can reach more than 200 grams in half a year. It will be released in May and listed in 65438+February. Wild crucian carp grows slowly. After hatching in May and June, the body weight was only about 20-30 grams that winter, and it could not reach 100- 150 grams until the next summer.

1. What is the maximum size of crucian carp?

1, the maximum growth of wild crucian carp is about 1.5 kg, the maximum growth of cultured crucian carp is about 2 kg, and some species (engineering crucian carp) can grow to about 3-8 kg, depending on the living environment of crucian carp and other factors.

2. The culture cycle of crucian carp is generally about 6 months. Carassius auratus can grow rapidly under artificial breeding conditions. It can be released in May and put on the market in 65438+February. At this time, its weight generally exceeds 200 grams.

3. The growth rate of wild crucian carp is slow, and the growth cycle is about 2 years. The wild crucian carp hatched from May to June can only grow to 20-30g in that winter,100-150g in the summer and 200g in the winter.

4. Carassius auratus can be released in the middle and late April, and the dosage is 10000-25000 pieces/mu. When the fry grow to a certain extent, a proper amount of silver carp can be released, which can play the role of water regulation.

5. In order to provide natural bait for crucian carp, some aquatic plants can be cultured in the pond during the breeding period, and the content of protein in the feed should reach about 30% to meet the nutritional needs of crucian carp during its development.

2. Which water layer does crucian carp like to live in?

1, Carassius auratus likes to live underwater. When the water temperature is 0-30℃ (the suitable water temperature is 15-25℃), it can eat with its mouth open, and it is more active when the water temperature is 20℃.

2. Carassius auratus is adaptable and distributed in rivers, lakes, reservoirs, ponds and other waters all over China. In spring and autumn, crucian carp will swim in the shallow water area with dense aquatic plants on the shore for food. After entering summer, crucian carp will live in deep water or in the shade. After winter, crucian carp will go to deep water to avoid the cold.

3. Young crucian carp likes to eat fishy food, while adult crucian carp likes to eat plant food, especially when the weather gets warmer. When the weather is cold, crucian carp likes to eat fishy food.

4. Spring is the foraging season for crucian carp. At this time, their foraging activities are usually all-weather. In summer, crucian carp usually eat in the morning, evening and evening. Carassius auratus generally forages all day in autumn and around noon in winter.

May, March-July are the breeding periods of crucian carp, and it will enter the peak period in April-May.
