Detailed Explanation of Crayfish Farming Feed Formulas and Raw Material Combinations

The flesh of crayfish is delicious and has been loved by the general public, so many farmers have started raising crayfish. Raising crayfish requires regular feeding of feed, so what are the crayfish feed formulas?

1. Crayfish feed formulas

1. Juvenile crayfish formula feed

(1) The crude protein content in Formula 1 is about 45%, including: wheat bran 37%, fish meal 35%, peanut cake 25%, clam shell powder 3%;

(2) The crude protein content in Formula 2 is about 50%, including: fish meal 60%, wheat bran 22%, peanut cake 15%, minerals 3% and trace elements;

(3) The crude protein content in Formula 3 is about 45%, including: fish meal 50%, wheat bran 20%, soybean cake 20% and trace elements.

2. Adult crayfish formula feed

(1) Formula 1: wheat bran 50%, silkworm pupae 30%, soybean cake 10%, rice bran 5%, peanut cake 5%;

(2) Formula 2: wheat bran 30%, rice bran 22.5%, fish meal 20%, peanut cake 20%, silkworm pupae 7.5%;

(3) Formula 3: wheat bran 57%, fish meal 35%, peanut cake 5%, clam shell powder 3%.

During the crayfish farming process, soybean cake is used at a relatively high rate, with plant-based feed as the main type.

2. How to feed crayfish

1. Prepare feed combinations well for different growth stages. At the seedling stage, crayfish are mainly fed rotifers, cladocerans, and the larvae of copepod aquatic insects. In March and April, crayfish grow quickly, and they are mainly fed wheat bran, soybean cake, feed, pumpkin, sweet potato, and so on. As crayfish gradually grow, they can be fed some fish meat, snail, clam and mussel meat, earthworms, and animal offal from slaughterhouses, and so on, to fully meet the nutritional requirements for crayfish growth and development.

2. Feed according to feeding characteristics. Crayfish generally hide by day and come out at night, coming out at night to seek food. Feed twice a day, once in the morning and once in the evening, and increase the feeding amount in the evening, accounting for 70% of the whole day. Crayfish have the habit of occupying territory, so feeding should adopt the methods of fixed quality, fixed quantity, and fixed time to avoid scrambling.

Raising crayfish is very simple. They grow quickly, have a very wide feeding range, and also have strong adaptability to the environment. The feed formula can be adjusted according to different growth conditions.
