In general, the maximum weight of native crucian carp can reach about 1.5 kg, that of cultured crucian carp can reach about 2 kg, and that of engineering crucian carp can reach about 3-8 kg. The growth cycle of Carassius auratus is about 2 years. If it hatches in May-June, its weight will not reach about 2-3 grams until the winter of that year, 1-15 grams in the summer of the following year and 2 grams in the winter of the following year.

1. What is the maximum weight of native crucian carp

1. Weight

(1) Native crucian carp: refers to wild crucian carp, whose maximum weight can generally reach about 1.5 kg, and its weight growth rate is slow.

(2) Culturing crucian carp: The maximum weight can generally reach about 2 kg, and engineering crucian carp can reach about 3-8 kg, and the specific weight will be affected by the living environment.

2. Growth speed

(1) The growth cycle of wild crucian carp

is about 2 years. If it is hatched in May-June, it will only grow to about 2-3 grams in the winter of that year, 1-15 grams in the summer of the following year and 2 grams in the winter of the following year.

(2) The growth cycle of cultured crucian carp

is about 6 months. If it is stocked in May, it will weigh more than 2 grams in December of that year, and then it can be fished and marketed.

Second, the difference between native crucian carp and cultured crucian carp

1. Different body colors

(1) Native crucian carp: its body color is white, mostly silvery white, and some are golden yellow.

(2) cultured crucian carp: black body color and rough appearance.

2. Different appearance

(1) Native crucian carp: high back and thin body.

(2) cultured crucian carp: smooth back, fat body, big and soft belly.

3. Different body types

(1) Carassius auratus: The growth rate is slow and the body size is relatively small, because the food intake is not fixed.

(2) Culturing crucian carp: There is plenty of food, so it grows faster and is relatively large.
