Carassius auratus fry can generally be stocked in spring and autumn, especially in late May to mid-June, one or two months after the year or July-August. Wild crucian carp seedlings can grow about tens of grams a year, about 1 2; Culturing crucian carp fry artificially can be about150-200g a year, and it can be more than 250g a year if the natural bait is rich and the water quality is beautiful. Of course, different varieties of crucian carp fry have different growth rates. Take Xiangyun crucian carp as an example, the fry can grow to 750 grams a year.

1. When will the crucian carp fry be released?

1. The suitable stocking season for crucian carp fry is spring and autumn, especially from late May to mid-June, one or two months after the year or July-August. Before stocking, the fish pond should be cleaned up and excess silt should be cleaned up, and the thickness of silt should not exceed 20 cm. 2.5% trichlorfon powder was sprayed in the whole pond 1-2 days before the crucian carp fry went into the pond, so that the water in the pond was 1ppm. A week later, drain the pond, inject fresh water, and then cultivate.

2. Pond culture of crucian carp fry mainly includes polyculture in fish ponds, interplanting in fish ponds, interplanting in parent fish ponds and main culture in ponds. Mixed fish can generally be mixed with green grass, silver carp, carp and other fish species; In parent fish ponds, fish can generally be cultured in fry ponds such as grass and silver carp, but not in carp and tilapia.

2. How big can crucian carp fry grow in a year?

1, wild crucian carp seedlings can grow about tens of grams a year, which is about 1; Culturing Carassius auratus seedlings artificially can grow about150-200g a year, and it can grow more than 250g a year if the natural bait is rich and the water quality is beautiful. Of course, there are many varieties of crucian carp, and the growth rate of different varieties is different. For example, Xiangyun crucian carp can grow to 750 grams a year.

2. Carassius auratus has a wide diet, strong adaptability, strong fecundity and disease resistance, and does not require high water temperature. In order to grow rapidly, water quality and feed must meet its growth needs. In addition, farming experience is also very important. Once an emergency occurs, it should be dealt with in time, otherwise it is easy to have a large number of casualties.
