During the stocking season of organic grass carp, how to bait grass carp with forage

At present, it is the stocking season of organic grass carp, at this time, the water temperature is low, the vitality of organic grass carp is small, the scales are compact, it is easy to pull the net and catch, the fish is not easy to be injured, and the survival rate can be improved. Organic grass carp (Ctenopharyngodon idellus) is a typical herbivore, and young fish with 5cm body length begin to eat grass. Grass carp weighing more than 250 grams can feed 125 to 180 grams per day. When feeding grass carp with grass, you should grasp the following points:

Grass carp culture

First, feed the grass to be fresh and tender. Fresh and tender forage is rich in nutrition, less cellulose, grass carp like to eat, easy to digest, can make grass carp grow fast. Therefore, grass carp should be fed with fresh and tender forage as far as possible. Should be fed with parallel vein long leaf green grass, should not be fed with grass carp do not eat reticulate vein mass leaf forage, ryegrass, Sudan grass and wild long leaf grass is better. At the same time, we should also observe the grass carp eating grass, like herbivores should be more, in order to meet the growth needs of grass carp.

Second, it is not suitable to feed aquatic plants. According to experiments, grass carp can gain 1 kilogram of meat if they eat 15 kilograms of terrestrial aquatic plants, while eating raw aquatic plants requires 60 to 80 kilograms to gain 1 kilogram of meat. Therefore, in the case of insufficient sources of aquatic plants, they can be fed less or not.

Third, feed different fodder according to the specifications of the fish. Grass carp juvenile period, the mouth is small, can not feed thick, hard forage, it is appropriate to feed sedge, duckweed, etc., or fresh and tender long-leaf grass crushed before feeding. With the increase of the size of the fish body, the fish mouth also increases, so it can be transferred to feeding conventional fresh and tender forage.

Fourth, the feeding method should be appropriate. Grass carp should be fed regularly, sufficiently and evenly every day, and strive to spread the forage so that grass carps can eat well and eat well, so as to improve the effect of grass carp culture. The amount of feed should also be adjusted according to the weather, water quality and grass carp activities to meet the needs of grass carp for forage. It is strictly forbidden to feed grass carp that have been stored for too long and moldy to prevent grass carp from becoming infected with disease.
