Abstract

The invention discloses a method for efficient alternate aquaculture of macrobrachium rosenbergii and lobsters, and belongs to the technical field of aquaculture. The method comprises the following steps: (1) desilting and insolating a pond, and disinfecting the pond with calcined lime; (2) planting June dry grasses and waterweeds; (3) stocking lobster seedlings, spotted silver carps, silver carps, green loaches and macrobrachium rosenbergii seedlings; (4) feeding a compound feed or feeding a mixture of the compound feed and other vegetative and animal feeds; (5) keeping the pH value of pond water at 7.5 to 8.5 to enable the dissolved oxygen content in the pond to be not less than 4 mg / L, and controlling the transparency at 30 to 40 cm; (6) catching the macrobrachium rosenbergii and the lobsters. The method fully considers the temperature condition and the growth characteristics and the aquaculture characteristics of the macrobrachium rosenbergii and the lobsters, and the adopted aquaculture mode and the technology design are reasonable; aquaculture resources are effectively used, the utilization rate of the pond is increased, and the economic benefits of farmers are obviously increased; by multi-species aquaculture and reasonable arrangement of crop rotation, the capacity of the farmers for resisting the aquaculture risk is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating Macrobrachium rosenbergii and crayfish. Background technique [0002] Macrobrachium rosenbergii, also known as white-footed shrimp, Malaysian prawn, money shrimp, Penaeus vannamei, etc., is an omnivorous aquatic animal and is the largest species of freshwater shrimp. It is known as the king of freshwater shrimp. The origin is concentrated on the coast of Ecuador. It is one of the three largest shrimp species in the world with the highest breeding volume. It has the characteristics of large, ferocious, fast production, good adaptability, rich nutrition, and delicious meat. It is the most popular among consumers. One of the aquatic products. In freshwater aquaculture in my country, Macrobrachium rosenbergii becomes the second most efficient agricultural production species after river crab. Especially in the middle and lower reaches of the ...
