High-yield ecological culturing method of high-quality macrobrachium rosenbergii

Abstract

The invention discloses a high-yield ecological culturing method of high-quality macrobrachium rosenbergii. The method comprises the steps of pond processing, performing desalination on shrimp sprouts, performing feeding management, 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 the shrimp 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 high survival rate, high yield, high quality, relatively short culturing period, etc. The method further has advantages of realizing substantial economic benefit, promoting development of an aquatic product breeding industry, increasing economic benefit of farmers and realizing high popularization value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a high-yield ecological culture method for high-quality Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii), also known as Malaysian prawns, freshwater long-arm prawns, money prawns, and large river prawns, is the largest freshwater prawn in the world. It lives in freshwater or brackish waters in these areas throughout the year, and in Breeds in tidal estuary areas. Macrobrachium rosenbergii is the largest individual in Macrobrachium genus. It has important economic value because of its large body, wide feeding habits, few diseases, easy survival, fast growth and good nutrition. Large-scale artificial breeding has been carried out in more than ten provinces and cities such as Guangdong, Guangxi, Hunan, Hubei, Jiangsu, Shanghai, and Zhejiang. [0003] However, in recent years, due to the aging of the bree...

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 quality of Macrobrachium rosenbergii 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 Macrobrachium rosenbergii, which not only increases the cost of breeding, but also increases the risk of breeding , greatly reducing the efficiency of Macrobrachium rosenbergii farming
