Abstract

The invention discloses a selenium-rich prawn feed. The selenium-rich prawn feed is prepared by mixing selenium-rich raw materials and feed raw materials at the mass ratio of 1:5-15, wherein the preparation process of the selenium-rich prawn feed comprises the following steps of: weighing the selenium-rich raw materials and the feed raw materials in proportion, and sufficiently stirring and uniformly mixing respectively for standby; placing selenium-rich feed mixtures on a ventilating position at 25 DEG C for 48-72 hours for light treatment; and ball-milling selenium-rich feeds and feed raw material mixtures so that the product particle size of a final product is at a nanometer grade. The product prepared by the method disclosed by the invention is suitable for culturing selenium-rich prawns and obvious in effect and has important practical significance on developing selenium-rich prawn aquaculture.

Description

technical field [0001] The invention mainly relates to the technical field of marine product cultivation, in particular to a selenium-enriched prawn feed. Background technique [0002] Shrimp is an important marine economically cultured species. Belongs to the phylum Arthropoda, Crustacea, Decapod, Penaeidae, and the genus Penaeus. Prawns are large in size and are commonly known as prawns. The body of prawns is long and slightly flattened, dioecious, adult frog prawns are larger than males, and their body color is also different; the body color of Chinese prawns is gray and blue, and the body color of males is yellow. The body of prawns is covered by a layer of chitin exoskeleton carapace, which is secreted by the epidermal cells below it. Females are generally 16-22 cm long and weigh about 50-80 grams, and the largest can reach 30 cm and weigh 250 grams; males are smaller, with a body length of 13-18 cm and a weight of 30-50 grams. Prawns are wide-temperature and wide-h...
