Long‐term stock assessment and growth changes of the Japanese sardine ( Sardinops melanostictus) in the Sea of Japan and East China Sea from 1953 to 2006
Abstract We estimated the stock size of Japanese sardine ( Sardinops melanostictus ) in the Sea of Japan and East China Sea since 1953 using cohort analysis based on the changes of growth patterns. Growth of Japanese sardine, estimated by using annual rings on archived scales since 1961, showed that...
