Because of the high market demand, many areas have chub fish farming, the following to understand the chub fish farming technology.
One, what does the chub eat
The chub belongs to a typical filter-feeding fish, relying on the special structure of the gills to filter the plankton in the water, life-long zooplankton for food, in the stage of the fry mainly eat zooplankton, up to 1.5 cm or more gradually turned to eat phytoplankton, and like to eat grass carp feces and put in the chicken, cow dung, but also ate soya bean milk, soybean dregs powder, bran and rice bran and so on. It also eats soybean milk, soybean meal, bran and rice bran, etc., and prefers to eat artificial micro-granular feed.
The chub is very interested in acidic food and has an appetite for bad food.
The chub likes to eat rotten food, often with grass carp breeding chub eat grass carp feces, so there is a grass to raise three chub said.
Two, chub fish farming techniques
1, the establishment of fish ponds
Want to a large number of breeding chub fish, it is necessary to establish a suitable fish ponds, this fish requires a large area of fish ponds, preferably between 4 and 8 acres, the depth of water should be more than two meters, and in the stocking of fish before the use of organic fertilizers to cultivate organic fertilizers, organic fertilizers can be chosen to dress the matured animal feces or cake fertilizers, but the fertilizers To the right amount, not too much concentration.
2, stocking fry
Farming chub should be stocked in the summer of each year, stocking can be divided into two kinds of mono-culture or mixed-culture, mixed-culture that is, then put into the chub fry, then put into the other kinds of fry, so as to maintain the balance of ecological environment in the pond, conducive to the growth of a variety of fish, but also to create a higher economic benefits, chub is most suitable for carp chub, etc. fish farming together. The chub is best suited for breeding with carp, chub, and other fish.
3, daily management
The chub is an animal that usually takes the plankton in the pond as its main food, so it is important to keep the water quality of the pond fertile and the number of plankton high during the breeding period, so that it can provide enough food for the chub.
Additionally, during the cultivation of chub, artificial input feed, must maintain the principle of timing and positioning, quality and quantity, only in this way can improve the utilization rate of feed.
4, overwintering management
The temperature drops significantly in late fall and early winter, when the activity of the chub will be reduced, when the temperature drops below ten degrees, the chub will almost not be in the feeding, this is a must to take out the chub in the pond, focus on stocking in the deeper ponds, if there are no conditions, it is necessary to sell all chub all empty after the sale in the next year after the warm weather Re-stock with fry.
Chub farming is very promising, and if you do a good job, you can get a lot of economic benefits, but no matter what kind of aquaculture industry, there are risks, and you must fully consider these factors before committing to aquaculture.
