How Do Grass Carp Reproduce? Detailed Explanation of Breeding Methods and Techniques

Grass carp is one of our common edible fish and a common major species in aquaculture, with high nutritional value, feeding mainly on small plants and plankton. So how do grass carp reproduce?

1. How do grass carp reproduce

Oviparous. Grass carp mainly reproduce by means of egg-laying. Grass carp farming has a history of more than 1700 years, and it is one of the higher-yielding species among freshwater farmed fish.

2. How to feed grass carp

1. Grass feed: Feed different grasses according to size. During the juvenile stage, feed some nutgrass and small duckweed, or chop fresh tender long-leaf grass and feed it. As the fish grow, transition to feeding regular grass. When feeding grass to grass carp, feed on time, in sufficient quantity, and evenly every day. The grass needs to be scattered so the fish can eat their fill, and the feeding amount should be adjusted according to the weather, water quality, and fish activity, to suit the fish's requirements for grass. Do not feed grass that has been stored too long or that is moldy and spoiled, to avoid disease infection.

2. Pellet feed: Large-scale farming requires feeding some feed. The feed mainly uses rice bran, wheat bran, soybean cake, and fishmeal as the main raw materials, with pellet feed as the main type. The protein content of the feed is 28-32%, supplemented by feeding some green fodder. Feed twice a day. After continuously feeding pellet feed for a period, stop for one week. Normally, vitamins and other medicines should be added to the feed, which can prevent grass carp from suffering from hepatobiliary syndrome.
