High-yield polyculture method of penaeus vannamei and macrobrachium rosenbergii

Abstract

The invention discloses a high-yield polyculture method of penaeus vannamei and macrobrachium rosenbergii. The method comprises the steps of pond processing, performing desalination on penaeus vannamei sprouts, then performing desalination on macrobrachium rosenbergii sprouts, inputting sprouts, performing feeding management and culturing management, etc. The baits which are fed in culturing according to the method of the invention comprise: a ferment material which is used for breakfasts and lunches of the sprouts and is composed of EM bacteria, milk powder and shrimp material in the inputting early period of the sprouts, a mixture which is composed of steamed and triturated eggs and spirulinas and the uniformly mixed shrimp material as suppers; and forage and ampullaria gigas which are fed every day in the middle and late period in culturing. According to the method of the invention, a biological characteristic is utilized; a polyculture mode of the penaeus vannamei and the macrobrachium rosenbergii is utilized, thereby suppressing incidence rate of diseases, improving disease resistance and survival rate of the shrimps, improving unit-area benefit and promoting benefit of farmers.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a high-yield polyculture method of Penaeus vannamei and Macrobrachium rosenbergii. 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. [0003] 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 ...

Problems solved by technology

[0004] However, in the process of freshwater culture of Penaeus vannamei in recent years, due to the aging of the culture ponds, the deterioration of the ecological environment, the lag in the renewal of the culture model, 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 completely destroyed. The annihilation of the army severely restricted the rapid development of the freshwater vannamei industry
