The aquatic plants in the crayfish culture pond are actually very good plant bait for crayfish, including some plankton in the pond. There are also bean dregs, bean cakes, rapeseed cakes, wheat bran and so on, which can be used to feed crayfish.
However, it must be noted that crayfish should not be fed with powdery feed, such as wheat bran, and should not be directly sprinkled into the pond, so as not to muddy the pond water and block the gills of crayfish. It needs to be stirred with water, exposed to the sun for a day, and then fed.
There are many things that can be used as crayfish animal feed, such as chicken, duck and fish scraps from slaughterhouses, internal organs of poultry and livestock, and wild miscellaneous fish and shrimp that are not easy to sell in the market. These are all made of animal feed, and the price and income are relatively low. Of course, you can also choose the right ingredients according to your local conditions.
Extended data:
Lobsters mainly eat at night, so they feed 70 ~ 80% of the bait all day at night. Bait should be thrown into the shallow water near the pond, and the wells should be timed, fixed, quantitative and qualitative. Each pond can be equipped with 2 ~ 4 bait observation stations.
Observe whether the bait is finished every morning to decide the amount of bait to be fed that day. Too little bait will inhibit the growth of lobsters or kill each other because of hunger, and too much will increase the cost and worsen the pond environment. It is not good for the growth and molting of lobsters.
The bait can be prawn bait or lobster bait. The amount of bait cast throughout the day should be based on eating, eating and leaving no residual bait. Generally, shrimps are fed at 20-25% of their body weight, middle shrimps are fed at 1 5-20% of their body weight, and prawns are fed at10-0/5% of their body weight, twice a day,1time in the morning and evening.
