Experimental Study on the Disease-preventing Model of Culturing Chinese Sucker(Myxocyprinus asiatius)in River Crab(Eriocheir sinensis)Pond

摘要

From 2015 to 2016,the hepatopancreatic lesion syndrome had a higher mortality rate,which caused great economic losses to farmers.In order to study the high-efficiency disease-preventing crab pond intercropping mode,an experiment was successfully conducted to intercrop Chinese sucker(Myxocyprinus asiaticus)in a crab pond in 2017.We optimized the traditional stocking mode,and mainly cultured river crabs when intercropping Chinese suckers.Meanwhile,the cultivation environment was strengthened,and the test pond was not affected by disease throughout the year.The results showed that the production benefits were river crab 115 620 yuan/hm 2,Chinese sucker 44 280 yuan/hm 2,and silver carp and bighead carp 5 418 yuan/hm 2,with a total output of 165 318 yuan/hm 2,and the output-input ratio was 1∶1.72.The Chinese sucker-intercropping river crab culture mode promoted the improvement of pond culture environment,effectively controlled the occurrence of hepatopancreatic lesion syndrome,and significantly improved the economic benefits of crab pond culture.
