What do crabs eat in crab farming?

Crabs are omnivorous aquatic animals with a wide range of food sources, which can be roughly divided into three categories: natural bait, artificial animal bait and artificial plant bait.

Natural bait

All kinds of creatures that crabs like to eat and grow naturally in water or on land are called natural baits. Natural bait mainly includes phytoplankton, aquatic plants, benthos, terrestrial animals and plants and so on.

1. Phytoplankton: including diatoms, Chrysophyta, dinoflagellate, Euglenophyta, Chlorophyta, etc., which are the feed for early young crabs and zooplankton.

2. Zooplankton: rotifer, Cladocera, flexopod, etc., is a good feed for it.

3. Aquatic plants: including bitter grass, verticillium verticillata, Potamogeton crispus, Rabdosia malayensis, turnip, duckweed, water lily, water peanut, golden grass, etc., are its main natural bait.

4. Zoobenthos: snails, clams, clams and water earthworms in the water are its best feed.

5. Terrestrial animals and plants: including yellow powder insects, earthworms and ryegrass, Equisetum equisetum, aggregate grass and so on.

Artificial animal bait

Artificial animal bait mainly includes snail, clam, clam, silkworm pupa, yellow powder worm, earthworm, small miscellaneous fish, fly maggot, livestock and poultry viscera and so on.

Artificial plant bait

Artificial plant food mainly includes soybeans, bean cakes, vegetable cakes, cottonseed cakes, wheat, rice bran, bean dregs, lees, sauce dregs, peanut cakes and so on.

In the process of breeding, we can not only feed a certain kind of bait, but should be fed comprehensively according to the actual situation, only in this way can we effectively improve the efficiency of crab culture.
