Formula for preparing bait for young portunus trituberculatus by adding enteromorpha powder

Abstract

The invention discloses a formula for preparing bait for young portunus trituberculatus by adding enteromorpha powder. The bait for young portunus trituberculatus comprises the following components in percentage by weight: 25% of fish meal, 13% of bean cakes, 20% of casein, 5% of brine shrimp powder, 4% of sleeve-fish paste, 2.5% of enteromorpha powder, 16.5% of alpha starch, 8.5% of dextrin, 2% of monocalcium phosphate, 3% of fish oil and 0.5% of vitamin for a feed. Enteromorpha powder is added into the bait for the young portunus trituberculatus, has the fineness of 200 meshes above, is rich in active substances, can enhance the absorption of proteins by the young portunus trituberculatus body, eliminates the intestinal tract of the young body, and improves the survival rate of the young portunus trituberculatus body.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a formula for adding enteromorpha powder to make bait for young portunus crabs. Background technique [0002] Portunus trituberculatus is one of the four major aquaculture leading industries in Ningbo, and the situation of Portunus trituberculata breeding in Ningbo has become a barometer of my country's Portunus aquaculture industry. However, low-value shellfish, which are high-quality bait organisms for Portunus trituberculatus, cannot meet the needs of breeding due to limited resources, and the nutrition of small miscellaneous fish is monotonous and unbalanced, and the residual bait is easy to pollute the water quality, resulting in eutrophication and induction of water quality. disease. The existing Portunus bait is not conducive to the absorption of bait protein by Portunus juveniles, which easily causes intestinal blockage of Portunus juveniles, and the survival rate of...

Problems solved by technology

However, low-value shellfish, which are high-quality bait organisms for Portunus trituberculatus, cannot meet the needs of breeding due to limited resources, and the nutrition of small miscellaneous fish is monotonous and unbalanced, and the residual bait is easy to pollute the water quality, resulting in eutrophication and induction of water quality. disease

The existing Portunus bait is not conducive to the absorption of bait protein by Portunus juvenile crabs, which may easily cause intestinal obstruction of Portunus juvenile crabs, and the survival rate of Portunus juvenile crabs is low
