Problems solved by technology

At present, tilapia farming is mainly based on the traditional intensive farming model, relying on high-density stocking, large-scale feeding and continuous replacement of water bodies to achieve high-efficiency farming purposes. With the increase of breeding costs such as pond rent and pond rent, the profit of breeding is getting lower and lower, causing many farmers to be on the verge of meager profit or loss

Abstract

The invention discloses a pond ecological poly-culture method of oreochromis niloticus and macrobrachium rosenbergii. The pond ecological poly-culture method comprises the following steps: step 1, culture pond construction: a plurality of net cages are arranged in a culture pond, have a certain distance from the edge of the culture pond and are not in contact with the bottom of the culture pond; step 2, fry and young shrimp putting: firstly, macrobrachium rosenbergii young shrimps are put in a space outside the net cages in the culture pond, and then, oreochromis niloticus fries are put in the net cages; step 3, feeding management: firstly, macrobrachium rosenbergii feed is fed on the periphery of the culture pond, and then, oreochromis niloticus feed is fed into the net cages. The pond ecological poly-culture method discloses by the invention has the benefits that the farmer breeding cost is reduced, the pond water quality is regulated, and the yield of the oreochromis niloticus and the macrobrachium rosenbergii can also be improved.

Description

technical field [0001] The invention relates to the field of fish and shrimp farming. More specifically, the present invention relates to a pond ecological polyculture method of Gifu tilapia and Macrobrachium rosenbergii. Background technique [0002] Tilapia is one of the fishes promoted by the Food and Agriculture Organization of the United Nations to the whole world. Tilapia has been promoted in 115 countries and regions. At the same time, it has the advantages of fast growth, high yield, easy fishing and breeding, and the meat is delicate and delicious, with seamless thorns, etc., and is favored by domestic and foreign consumers. At present, tilapia farming is mainly based on the traditional intensive farming model, relying on high-density stocking, large-scale feeding and continuous replacement of water bodies to achieve high-efficiency farming purposes. With the increase of breeding costs such as pond rent and pond rent, the profit of breeding is getting lower and lo...
