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 the cultivation of broodstock of Penaeus monodon
Therefore, the application of granular compound feed in the artificial cultivation of broodstock of Penaeus monodon has not been seen so far.
Although Marsden et al. (1997) completely replaced natural baits such as squid and mussels with a soft pellet feed, which could increase the spawning times and nauplii survival rate of broodstock of Penaeus monodon, but the feed used was mainly fresh and live. Formulated with biological ingredients, it cannot be called a real compound feed
Due to the inability to obtain an ideal compound feed for artificial broodstock, at present, the cultivation of broodstock of Penaeus monodon can only rely on feeding fresh and live bait to ensure the nutrient supply during the breeding period

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...
