What bait do grass carp like to eat? Introduction to common bait types
Grass carp is one of the four major Chinese carps in freshwater aquaculture in China, also known as huan, oil huan, grass huan, white huan, wuqing, etc. It is a fish of the genus Ctenopharyngodon in the subfamily Leuciscinae of the family Cyprinidae, order Cypriniformes. It inhabits rivers and lakes in plain areas, generally preferring the middle and lower layers of the water and nearshore areas with abundant aquatic plants. Now let's take a look at what bait grass carp eats!
What bait do grass carp eat?
Grass carp has a lively temperament, swims quickly, often forages in groups, and is gluttonous by nature. It is a typical herbivorous fish. At the fry stage, it feeds on zooplankton. At the juvenile stage, it also eats insects, earthworms, algae, duckweed, etc. When its body length reaches about 10 cm or more, it feeds entirely on higher aquatic plants, especially plants of the grass family. The plant species it consumes vary with the condition of the food base in its living environment.
Ecological habits of grass carp
Grass carp generally prefers to inhabit the middle and lower layers of rivers, lakes, and other waters, as well as nearshore areas with abundant aquatic plants. It has the habit of river-lake migration. Sexually mature individuals spawn in flowing water such as rivers and reservoirs. After spawning, the parent fish and juvenile fish enter tributaries and lakes connected to rivers, usually feeding and fattening in flooded shallow beach grasslands and floodplain areas as well as affiliated water bodies of main and tributary streams (lakes, small rivers, channels, and other areas overgrown with aquatic plants). In winter, they overwinter in deep water of the main stream or lakes.
Feed formulas for grass carp
1. Rice straw 50%, rice bran 25%, soybean cake 25%. For every 100 kg of the above mixture, add another 10 kg of flour by-product as a binder. The crude protein content of the feed is 23.35%, the feed coefficient is 2.8, and the feeding size is about 0.05 kg per fish.
2. Rice straw 50%, rice bran 22.5%, wheat bran 5%, soybean cake 15%, fish meal 5%, bone meal 1%, salt 0.5%, vitamin additive 1%. The crude protein content of the feed is 18.78%, and the feed coefficient is 2.4.
3. Flour 30%, rice bran 8%, wheat bran 38%, soybean cake 10%, fish meal 10%, yeast powder 2%, premix 2%. The feed coefficient is 1.9. If green feed is additionally fed, the feed coefficient is 2.2.
4. Rice straw powder 50%, soybean cake 20%, flour 30%. The feed coefficient is 4.9. If soybean cake is reduced from 20 to 10 and green feed is additionally fed, the feed coefficient is 13.
5. Flour 30%, fish meal 10%, soybean cake powder 15%, wheat bran 25%, rice bran 20%. On the premise that the total amount of the basic diet remains unchanged, according to actual conditions, another 12% sweet potato powder, 0.5% salt, 2% auxin, and 2% calcium hydrogen phosphate may be added. The feed coefficient is 4.8.
