Embodiment 1

[0033] A high-yield polyculture method of Penaeus vannamei and Macrobrachium rosenbergii, comprising the steps of:

[0034](1) Whole pond: Choose a pond that is leeward to the sun and can store 1.5-2m of water. On March 20, 2017, grow taller rice, Hydrilla verticillium and bitter grass at the bottom of the pond. The height-increasing rice, Hydrilla verticillium and Erythrina fragrans are planted in subregions, and the corresponding planting areas account for 25%, 25% and 25% of the total pond area respectively. The height-increasing rice is planted with a row spacing of 80 cm and a plant spacing of 80 cm. The row spacing of Hydra verticillium and Erytheria galerica is 3 m respectively, and the plant spacing is 1 m.

[0035] (2) Desalination of Penaeus vannamei seedlings: Prepare a small pond of 2-3 mu on March 15, 2017, with a water intake of 80cm, and filter the water inlet with a double-layer 80-mesh mesh. Acres of quicklime is sprayed and disinfected in the whole pond; a c...

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 ...
