How much is the price of crucian carp fry? How to cultivate high quality and high yield?

Crucian carp grow slowly, about two years of sexual maturity, but the reproductive ability is very strong, in running water and still water can reproduce offspring, suitable for large-scale breeding. So how much is the price of crucian carp fry? How to cultivate high quality and high yield?

What is the price of crucian carp fry?

The average price of crucian carp fry is about 1112 yuan / kg, but sometimes it will drop to about 7 yuan / kg due to changes in market demand.

Of course, it is also possible to cultivate fish fry on their own. in fish fry cultivation, the density of fry in the pond is often too high, which is not conducive to the growth and management of fry, so it is necessary to cultivate fry in separate ponds in time. Usually after 7 to 10 days of larval rearing, the fry is carefully and slowly pulled up in a spray (fry) cage or bucket box and moved to a pre-prepared fry pond a few hours later. The cultivation method is the same as above.

Second, how to cultivate crucian carp with high quality and high yield?

1. Understand the growth habits of crucian carp.

(1) love grass and be gregarious

Because the aquatic plants are rich in bait, sufficient oxygen and strong concealment, the weeds and between cattails and reeds have become a place for crucian carp to play, find food and hide in groups. Crucian carp mild timid, afraid of disturbance, a little wind blowing grass, immediately dive into the deep water or grass to hide.

(2) miscellaneous eating habits

Crucian carp eat everything from insects to algae, from meat to vegetarian bait. However, due to different seasons, the water is cold and warm, and their eating habits are also emphasized. Generally speaking, the weather cold water temperature is low, they like to eat earthworms, red insects and other meat bait, hot water temperature is high, they like to eat a variety of dough and other vegetarian bait.

2. Set up a special pond

The pond area of the main culture crucian carp should not be too large, generally about 2 mu is appropriate, should not exceed 4 mu; the pond bottom is required to be hard, generally the silt thickness is less than 10 cm, and the silt must be cleared when it exceeds 10 cm, so as to facilitate the fishing of crucian carp; the ridge is solid and does not leak, and the inlet and outlet should install a firm and reliable fish fence, which should be 50 cm higher than the highest water level of the pond.

At the same time, medicine should be used to clear the pond before stocking the fish in the pond to kill the pathogens and harmful substances in the pond. Ponds with adequate water sources can drain the water from the ponds for dry cleaning and sprinkle them with quicklime or bleached pulp or the whole pond. The pond with constant drainage can be cleared with water, and the fish can be released after a week.

3. Stocking density

From the point of view of the economic benefits of culture, the stocking quantity is more than 2000 per mu, although a higher yield can be obtained, but the commercial fish is small, the sales price is low, and the benefit is not ideal. The stocking amount is less than 1000 fish / mu. Although the commercial fish is large, the total yield is not high and the sales income is low. 1400 fingerlings with a weight of 30 grams per mu or 1200 fingerlings of 50 grams per mu, with an appropriate amount of silver carp, bighead carp and summer grass carp, with a total number of no more than 600. the net yield of crucian carp is more than 500kg and that of other fish is about 200kg.

4. Daily management

(1) Water quality

For conditional ponds, new water should be injected frequently to keep the water environment clean. The amount of water each time should be 1 × 4 × 1 × 3 of the total amount of water in the pond. The water level of the pond should be adjusted continuously with the fish growth and seasonal changes, and the water saving should be deeper in the high temperature period and the fish feeding season, so as to increase the fish activity space.

(2) feeding

The juvenile fish were fed 3-5 times a day, and the adult fish were fed 2-3 times a day. Crucian carp have poor predation and need to be fed carefully for at least 15 minutes at a time, and feed on a fixed feed table, or choose a hard soil bottom as a fixed feeding point to prevent feed from sinking into the mud and causing waste.
