Embodiment 1

[0017] A culture method for improving giant macrobrachium rosenbergii survival rate, it comprises the following steps:

[0018] 1) Pond construction: choose a pond with an area of ​​5 mu and a depth of 1.8 meters as the breeding pond, and arrange a layer of bamboo bamboo at the bottom of the breeding pond. Ground dill: Arrange 6 feeding platforms evenly inside the breeding pond, each feeding platform can be lifted from the breeding pond and viewed, and an aeration system and a centralized heating area are arranged in the breeding pond; The heating area is separated from the water in other areas of the culture pond by a thermal insulation film, and a heating system is arranged in the heating area; the area of ​​the heating area accounts for 50% of the entire culture pond.

[0019] 2) Water quality adjustment: Use tea meal and quicklime to sterilize the breeding pond; at the same time, control the pH value of the pond water at 7.8.

[0020] 3) Shrimp seedlings: choose to put sh...

Abstract

The invention discloses a culture method for improving a survival rate of macrobrachium rosenbergii. The method comprises the following steps: 1) building a pond: selecting a pond with an area of 5-10mu and a depth of 1.8-2.2 meters as the culture pond; arranging a layer of phyllostachys edulis at the bottom of the culture pond, and planting vallisneria natans, hydrilla verticillata, potamogetonwrightii, and Diluocai around the culture pond; 2) adjusting water quality: performing sterilization treatment on the culture pond by utilizing camellia oleifera seed cakes and quicklime; 3) throwingyoung macrobrachium rosenbergii: throwing the young macrobrachium rosenbergii from the February to the March every year, wherein the number of the young macrobrachium rosenbergii thrown into per mu ofthe culture pond is 1-1.5 million; and 4) performing culture management: starting an aeration system and a heating system, and performing concentrated feeding in heating areas; and after feeding is performed for 2-3 months, heating water of the whole culture pond, and when the water in the culture pond is heated to the temperature of 28-32 DEG C, performing distributed feeding. According to the invention, the method is simple and easy to implement and promote, can improve the survival rate of the macrobrachium rosenbergii to be 70% or more, and has broad development prospects and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of macrobrachium rosenbergii culture, in particular to a culture method for improving the survival rate of macrobrach rosenbergii. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawn and freshwater long-armed prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide appetite, good meat nutrition, and short breeding cycle. Since the artificial cultivation of Macrobrachium rosenbergii began in the 1960s, it has developed rapidly, and it is more common to breed this shrimp in Southeast Asian countries and some other regions. At present, there is a problem of low yield in artificial feeding of Macrobrachium rosenbergii. The reason is that the survival rate of Macrobrachium rosenbergii is not high; it is found through research that the survival rate of Macrobrachium rosenbergii in artificial feeding in my country is generally about ...
