The invention relates to the technical field of fish and
shrimp culture, in particular to a channel
catfish and
macrobrachium rosenbergii
intercropping method and a catching and sorting
system.The method comprises the following steps that 1, pond preparation is conducted, specifically, pond basic conditions, a dam, a
spillway and a
buffer zone are included, and disinfection is conducted; 2, fry
stocking, wherein
macrobrachium rosenbergii
stocking, channel
catfish stocking and filter-feeding animal stocking are included; step 3, feed preparation; step 4, feeding with feed; 5, daily management, wherein
water quality regulation and control, temperature regulation and control and
disease prevention are included; step 6, capturing; 7, sorting the fishes and the shrimps; according to the method, through
intercropping of channel
catfish and
macrobrachium rosenbergii, full utilization of space is achieved by utilizing
living space characteristics of different water bodies; the two kinds of fishes are omnivorous animals, so that certain overlapping exists in the food range, and the utilization efficiency of the feed is improved to a certain extent; in addition, material exchange of water can be promoted to improve
water quality. And the method has obvious ecological and
economic benefits.
