Animal feed: such as the leftovers of dead fish, pigs, cows, chickens, ducks and fish intestines. Lobsters with strong fishy smell are very popular. In addition, there are snails, mussels, earthworms and water worms. The ditch is full of crayfish's favorite food, as well as dried small miscellaneous fish, fish meal, shrimp powder, snail powder, egg pupa powder, pig blood, pig liver and pig lung.
Plant bait: mainly refers to phytoplankton and aquatic plants, as well as duckweed, grain, bean cake, rice bran, soybean meal, wheat bran, rapeseed cake, vegetable oil, brewer's grains and so on. Plant feed beans mainly supplement protein, which can help the nutritional needs of crayfish. Soybean meal combined with unicellular algae, yeast and plankton is a very good protein bait for cultured shrimp larvae.
Artificial compound feed: The nutritional requirements of crayfish are met by artificially preparing the proportion of animal and plant feed, and then processed into feed according to the formula, and some minerals, vitamins and disease prevention drugs are added appropriately. Crayfish need different pellet feeds at different growth stages. In feed processing technology, attention should be paid to the viscosity of compound feed to make it into strips or sheets for freshwater crayfish to eat. Ensure sufficient protein content.
