Fresh water ecological culturing method of penaeus vannamei

Abstract

The invention discloses a fresh water ecological culturing method of penaeus vannamei. The method comprises the steps of pond processing, performing desalination on shrimp sprouts, performing feedingmanagement, performing culturing management, etc. The baits which are fed for culturing according to the invention comprise the following components: a ferment material which is composed of EM bacterium, milk powder and shrimp material for breakfasts and lunches in the early period in shrimp sprout inputting, a mixture which is obtained through mixing triturated steamed eggs and spirulina and theshrimp material for suppers, and a forge and ampullaria gigas which are fed every day in the middle and later days in culturing. The method according to the invention has advantages of improving survival rate of the shrimp sprouts after inputting, promoting growing speed of the shrimp sprouts through a reasonable feeding method and the baits, improving disease resistance and quality of the shrimps, realizing high culturing profit, promoting development of an aquatic product culturing industry, increasing economic benefit of farmers and realizing high popularization value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a freshwater ecological cultivation method of Penaeus vannamei. Background technique [0002] Litopenaeus vannamei, also known as Litopenaeus vannamei, Penaeus vannamei, and Penaeus vannamei, is one of the three high-quality shrimp species with the highest aquaculture output in the world so far. It has the advantages of strong vitality, wide adaptability to salinity and temperature, strong disease resistance, high survival rate, rapid growth, high meat yield, long survival time out of water, suitable for high-density breeding, etc. It is an intensive high-yielding Excellent cultivars. It has been cultivated on a large scale in Jiangsu, Guangdong, Guangxi, Fujian, Hainan and other provinces in my country, and has achieved outstanding economic and social benefits. [0003] However, in recent years, due to the aging of the breeding ponds, the deterioration of the ecological en...

AI Technical Summary

Problems solved by technology

[0003] However, in recent years, due to the aging of the breeding ponds, the deterioration of the ecological environment, the lag in the update of the breeding model, and the uneven quality of the seedlings, especially the frequent occurrence of diseases such as white spot disease and stealing disease, the entire shrimp pond has been wiped out, severely restricting the production of Penaeus vannamei. The rapid development of the industry

In addition, in order to meet the different nutritional needs of prawns or improve disease resistance, excessive so-called nutrients or drugs are mixed in the feed, but they are rarely used by prawns, which not only increases the cost of breeding, but also increases the risk of breeding. The land reduces the benefits of vannamei farming
