The results showed that the cannibalism rate was significantly affected by individual size, post-larvae density and food abundance. When post-larval density increased from 50 ind / L to 110 ind / L,the average daily cannibalism rate increased by 358.07%. When larval density was more than 110 ind/L,cannibalism rate slightly increased. The average daily cannibalism rate decreased by 69.81% in 20 ind/mL food group than that of no-food group. The mix of individuals in different sizes could increase cannibalism rate significantly. Sufficient aeration could decrease cannibalism rate. The results indicated that insufficient food was a main reason to cause cannibalism in Penaeus monodon post-larvae. High stocking density and differences of individual size could induce and stimulate the cannibalism. %> http://jifro.ir/article-1-3863-en.pdf %P 547-557 %& 547 %! %9 Orginal research papers %L A-10-3317-1 %+ South China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences %G eng %@ 1562-2916 %[ 2021
