Experimental red crucian carp fry feed and application thereof

Abstract

The invention relates to the field of fish culture, in particular to feed for juvenile fishes in an experimental red crucian carp fry stage and application thereof. A formula of the experimental red crucian carp fry feed comprises, by weight percentage, 30-35% fishmeal, 6-12% of soybeans, 5-15% of peanut kernel cakes, 9-12% of wheat middling, 8-11% of wheat bran, 8-11% of corn, 5-10% of rice bran, 5-10% of potato flour, 0-5% of brewer's yeast, 1% of fish oil and 1% of a multidimensional premix. Main nutritional indexes of the feed satisfy the conditions that the crude protein content is equal to or higher than 33%, the crude fat content is equal to or higher than 6%, the crude fiber content is equal to or lower than 6%, the coarse ash content is equal to or lower than 12%, and the total phosphorus content is equal to or higher than 1.2%. The feed of the formula has balanced nutrition, good palatability to experimental red crucian carps and high feed conversion rate; the nutritional demands of experimental red crucian carp fry for normal growth and development can be met, and it is also favorable for effective control over the quality of the experimental red crucian carps and an environment thereof.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a fry feed for experimental red crucian carp and its application. Background technique [0002] Experimental red crucian carp is a new native experimental fish in my country, which has important application value. The experimental red crucian carp is an aquatic temperature-changing animal, which is suitable for the water environment experiment. The red crucian carp is domesticated from the red crucian carp. .lmg / L), the water temperature of the aquarium in the barrier environment can be controlled at 18 ℃ ~ 24 ℃, suitable for animal experiments involving the water environment, and has the advantages of aquatic ecotoxicology research and environmental safety evaluation. The experimental red crucian carp has morphological characteristics adapted to living in the aquatic ecological environment. The experimental red crucian carp is a spindle-shaped body with a suitable body shape, flat ...

AI Technical Summary

Problems solved by technology

In the experimental red crucian carp breeding industry of indoor breeding, in the scientific experiments carried out with the experimental red crucian carp, there is a lack of a standardized experimental red crucian carp full-price compound feed, which seriously affects the normal production of the experimental red crucian carp and the accuracy of the scientific test results.
