Ecological breeding method capable of improving yield of acrobrachium nipponense

Abstract

The invention discloses an ecological breeding method capable of improving yield of acrobrachium nipponense. The ecological breeding method capable of improving the yield of the acrobrachium nipponense comprises the following steps: (1) selecting a pond; (2) performing pretreatment on the selected pond; (3) cultivating aquatic plants; (4) carrying out preparation before stocking; (5) carrying outstocking of acrobrachium nipponense fries and fishes used for mixed breeding; (6) carrying out bait feeding; (7) regulating and controlling water quality; (8) carrying out aquatic plant conservation;and (9) carrying out fishing. The ecological breeding method capable of improving the yield of the acrobrachium nipponense provided by the invention adopts a breeding mode of two batches a year; and moreover, the techniques of pond clearing, shrimp nest setting, bait feeding, water quality control and density control in the breeding process are separately improved, so that the problems of damagesto the aquatic plants and the fishes used for the mixed breeding caused by pond clearing before stocking of the acrobrachium nipponense fries in autumn, poor concealment and low space utilization rateof artificial shrimp nests, unable meeting of needs of the acrobrachium nipponense in different growth stages by feeding and water quality control measures, culture resource competition between cultured acrobrachium nipponense and second-generation offspring of the acrobrachium nipponense and the like in the prior art are solved; and thus, the method is beneficial for improving the yield of the acrobrachium nipponense, increasing comprehensive economic benefits, as well as promoting healthy and sustainable development of the acrobrachium nipponense breeding industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological breeding method for increasing the yield of freshwater shrimp. Background technique [0002] Freshwater shrimp (Macrobrachium nipponense) scientifically known as Macrobrachium japonica is an important aquaculture species in my country's freshwater aquaculture industry because of its delicious meat, rich nutrition, fast growth, strong adaptability, and short growth cycle. In recent years, my country's freshwater shrimp aquaculture industry has developed vigorously, and the aquaculture output has continued to increase, and the annual output has exceeded 272,000 tons. [0003] At present, freshwater shrimp farming mostly adopts a breeding mode of two crops a year, and its farming technology is constantly improving, but there are the following problems in the breeding process that need to be improved urgently: (1) Dry the pond or splash a large amount of quicklime (...

Problems solved by technology

[0003] At present, freshwater shrimp farming mostly adopts a breeding mode of two crops a year, and its farming technology is constantly improving, but there are the following problems in the breeding process that need to be improved urgently: (1) Dry the pond or splash a large amount of quicklime (bleach powder) before the shrimp seedlings are stocked in autumn Disinfection not only seriously damages aquatic plants, but also is not conducive to the growth of polyculture fish; (2) The construction of artificial shrimp nests is mainly based on meshes and branches, and the concealment and space utilization are low; (3) Freshwater shrimp grows differently Different stages have different requirements for nutrition and breeding environment, and there are few phased feeding measures and water quality control measures for different growth periods in the breeding process; (4) Farmed shrimp competes with the second generation for food resources and breeding space, and the commodity rate is relatively low.
