What kind of feed is fed for mandarin fish culture? Mainly bait fish.

Mandarin fish culture is generally based on food fish, early food fish: wheat dace, Thai dace, crucian carp, silver carp, bighead carp, soil dace and carp and so on. Mid-term bait fish: wheat dace, soil dace and Thai dace fry. Late bait fish: because of the low temperature in winter, you can raise some overwintering bait fish such as silver carp, bighead carp and crucian carp.

What kind of feed is fed to mandarin fish culture?

1. Early bait fish: about 2 million fry such as silver carp, bighead carp, Thai dace, crucian carp, soil dace, wheat dace and so on are raised in mandarin ponds. This is the early feed for mandarin fish, and rough feeding such as wheat husk and peanut bran can also be put. About 20 days, bait fish grow to 2.5cm or so, you can use 0.7ppm copper sulfate and 0.5ppm strong chloroform disinfection, put in about 3 cm of mandarin fish fry.

2. Medium-term bait fish: bighead carp, crucian carp, silver carp and other fish fry can be specially prepared in several fish ponds, and 300000 wheat dace, soil dace and Thai dace fry can be mixed in fish ponds as mid-term bait fish for mandarin fish.

3. Late-stage bait fish: in addition to self-breeding, you can also purchase bait fish. In the later stage of culture, the winter temperature is relatively low, and the dace bait is easy to freeze to death. We should prepare some bait fish that can survive the winter in advance, such as silver carp, bighead carp, crucian carp and so on.

Culture conditions of mandarin fish

To build a culture pond for mandarin fish culture, it requires a sandy bottom, silt about 15cm, an area of about 5 mu, a water depth of more than 1.5m, good drainage and irrigation conditions, no pollution, the best flow of living water, and a pond with a small amount of submerged aquatic plants.

Mandarin fish special culture pond should not be too high density, easy to affect the water quality. Therefore, the drainage and irrigation conditions of the pond must be good, change the water regularly, keep the dissolved oxygen in the pond water at least more than 4 milligrams per liter, set up an aerator according to the specific situation, disinfect regularly, and so on.

How to cultivate bait fish

The selection of silver carp and crucian carp can improve the palatability and economic value of mandarin fish. The culture area of bait fish is about 4 times that of mandarin fish pond, and the stocking density is 30-500000 fish per mu.

Do not feed the fry immediately after it is released. You can feed the fry when they are foraging around the pond or when the number of zooplankton decreases. Feed is supplied in time in the early stage of cultivation, but in the later stage, it needs to be controlled according to its specifications, and the length of bait fish can be controlled around 4cm.

Can also be in mandarin fish mixed with some fast breeding bait fish, as live feed, with a thin net to divide the fish pond into two parts, while raising mandarin fish, while raising bait fish, breeding express fish can pass through the thin net to become mandarin fish food.
