Chub is a filter-feeding freshwater fish, mainly feeding on zooplankton, from the fry to the adult stage is to zooplankton (rotifers, branchiostomes, copepods, etc.) as the main food, up to 1.5 cm or more when the part-time phytoplankton, it is a typical planktonic food fish. Artificial culture, chub also eat soybean cake, bran, rice bran, lees and other artificial feed, as well as livestock feces (chicken manure, cow dung, etc.), which artificial micro-particle with the feed can also meet the chub's food needs.

First, what does the chub eat

1, the chub mainly feed on zooplankton, from the fry to the adult stage is to zooplankton (rotifers, branchiostomes, copepods, etc.) as the main food, up to more than 1.5 centimeters long and eat phytoplankton, it is a typical plankton feeding fish. Artificial culture, chub also eat soybean cake, bran, rice bran, wine lees and other artificial feed, as well as livestock feces (chicken manure, cow dung, etc.), more like to eat artificial micro-granular feed.

2, chub is a mild filter-feeding fish, do not compete for food, do not grab food, in the case of other fish grabbing food, usually only in the periphery of the watch, do not enter the food table to grab food, so the feed feeding can only be mono-culture, can not be mixed with other predatory fish. Feed adhere to the quality, timing, positioning, quantitative? Four? The principle of feeding according to the feeding rhythm of the fish species to be fed, the feed can not be too single. The feeding intensity varies with the season, and is generally greater in April-October each year.

Second, how to breed chub

1, the establishment of fish ponds

If a large number of breeding chub, first of all, to build a suitable fish pond. Fish ponds should be a certain distance from the city, the size can be determined according to the scale of the breeding, fish pond area is better, preferably between 4-8 acres, the depth of water should be more than 2 meters, and in the stocking of fish before the application of organic fertilizer to cultivate, so that the chub can be supplied with nutrients, to ensure that the normal growth of the chub. Organic fertilizer can choose rotted animal manure or cake fertilizer, but the fertilizer should be appropriate, the concentration can not be too large.

2, stocking fry

Chub farming should be stocked with fry, stocking can be divided into two kinds of mono-farming and mixed-farming. Mixed farming is to put the chub with other fish together, so as to maintain the environmental balance of the pond, all kinds of fish can grow normally, but also to create a higher economic benefits, the chub is most suitable for mixed farming with carp, chub and other fish.

3, daily management

The chub has the habit of feeding on plankton, so during the breeding period, we must keep the pond water quality is fertile, the number of plankton is high, so as to provide enough food for the chub. At the same time, it is also necessary to change the pond water frequently to ensure that the water quality is clean. In addition, during the cultivation of chub, artificial input feed should be fed regularly, and the feed can not be too single, only in this way can improve the utilization rate of feed.

4, overwintering management

The temperature drops significantly in late fall and early winter, and if you want the chub to survive the winter peacefully, the chub will almost not feed again when the temperature drops below 10 degrees Celsius, and then it is necessary to concentrate all the chubs in the pond together and stock them in the deeper ponds so that the temperature will not be so cold. If you don't have the conditions, you need to empty all the chub and sell them, and then start with the fry in the next year.
