Problems solved by technology

Studies have shown that the nutritional requirements of different species of broodstock are not consistent, and are greatly affected by factors such as living habits and individual size. The above-mentioned compound feed and nutritional enhancer for broodstock have no significant effect on promoting the gonad development of Penaeus monodon and increasing the gonad maturation rate
[0005] Penaeus monodon is the largest individual of all cultured prawn species. The sexually mature individual of its natural broodstock is much larger than its prawn species. It has certain special requirements for bait particle size, palatability, nutrition, etc., and does not like to eat artificial pellet feed It is the reason why it is difficult to apply artificial compound feed in t

Embodiment 1

[0026] Made from the following components: (by weight)

[0027] Highly Unsaturated Fatty Acids 10; Astaxanthin 1.5% Purity 7

[0028] Cholesterol 5; Vitamin C5;

[0029] Vitamin E1; Kelp powder 72;

[0030] The highly unsaturated fatty acid is liquid, wherein docosahexaenoic acid (DHA) plus eicosapentaenoic acid (EPA) accounts for 50.0-80.0% of the weight, and DHA / EPA is between 2.0-4.0; All components passed through a 100-mesh standard sieve.

[0031] Weigh various nutrients according to the above-mentioned parts, stir all the powders in a mixer for 15 minutes, then add highly unsaturated fatty acids and continue stirring for 15 minutes, and after mixing evenly, the feed additive for promoting maturation of Penaeus monodon broodstock is obtained. The obtained additives are vacuum-packed and sealed in 500g bags, then packed into specific packaging jars, and stored in a -20°C refrigerator.

Abstract

The sex gland mature promoting feed additive is used to promote the sex gland mature of adult tiger prawn. The sex gland mature promoting feed additive consists of liquid highly unsaturated fatty acid 5-25 weight portions, 1.5 % over astaxanthin 5-10 weight portions, cholesterol 5-10 weight portions, vitamin C 4-10 weight portions, vitamin E 1-3 weight portions and kelp powder 50-80 weight portions. The present invention may be well adhered to squid, clam warm and other live bait for adult tiger prawn to ingest and can promote the sex gland mature of adult tiger prawn obviously.

Description

technical field [0001] The invention relates to a feed additive for promoting the maturation of the gonads of Penaeus monodon, which is especially suitable for accelerating the ripening of Penaeus monodon reaching the mature age and specifications (body weight and body length) in artificial cultivation. Background technique [0002] Shrimp farming is the pillar industry of my country's aquaculture industry. Penaeus monodon (Penaeus monodon) is one of the three main cultured prawn species in my country. At present, the mature broodstock required for the seed production of Penaeus monodon is mainly obtained by fishing natural populations at sea. Due to the changes in wild Penaeus monodon resources, it is impossible to rely on fishing to ensure a stable supply of broodstock of Penaeus monodon; at the same time, due to the spread of White Spot Syndrome Virus (WSSV), wild Penaeus monodon and the environment The proportion of white spot syndrome virus in the natural host of WSSV...
