The productive development of crayfish is closely interrelated with the food supply of the reservoir. Providing sufficient food makes it possible to grow a healthy population of marketable crayfish.
Instructions
Step 1
Cancers are omnivores. They feed on plant and animal foods. The first type of food includes aquatic and semi-aquatic plants. These are elodea, hornwort, charovye algae. The leaves and stems of these plants contain large amounts of lime. Crayfish are attracted to rhizomes of reeds, sedges and reeds. The crustacean animal food includes the larvae of various insects, tadpoles, water worms and snails. Small fish may be present in the diet of crayfish. The daily food volume of cancer reaches 2% of the total weight of an individual.
Step 2
Adult crayfish need to be fed only during spring, summer and fall. In winter, crayfish require very little food, as they do not grow during this period. If you continue to feed your crayfish, unused food debris can cause the water to fade. The water temperature during feeding should be above 7 ° C. It is best to feed the crayfish in the evening. This is due to the nocturnal lifestyle of the animal. Food waste can be used as feed. Give crayfish spoiled meat, bread, fish, vegetables, and cereal grains. The food is spread on special square trays. This keeps the pond clean. The trays are equipped with small sides. The filled trays are lowered under water and fixed to the bottom.
Step 3
The diet of crayfish larvae and adults differs in composition. The larvae are fed with zooplankton. Slightly grown larvae are transferred to trout feed. Chopped meat and fish are gradually added to the feed. Be sure to monitor the amount of feed. It should be enough for all individuals. Hungry larvae can eat each other. The diet of larvae that grow up to 2 cm is replenished with filamentous algae.
Step 4
Adult cancers periodically attack each other. To avoid this, you need to add alder, potato and nettle leaves to your food. It is undesirable to give fresh fish. Cancers can vie for this type of food. In such battles, they lose their presentation.
