AGE AND GROWTH OF ANGLERFISH LOPHIUS-LITULON IN THE EAST CHINA SEA AND THE YELLOW-SEA

Age and growth of anglerfish Lophius litulon were examined using verte bral centra from specimens collected in the East China and Yellow Seas during January 1991 to April 1996. Monthly changes in the percentage frequency of a translucent band on the outer margin of centrum and the marginal increments indicated that ring formation occurred once a yea r mostly in April. Back-calculated total lengths for each sex were cal culated by the regression method using a standardized ring radius. The initial growth trend based on monthly collected young fish (less than or equal to 250 mm in total length) were compatible with the mean bac k-calculated total lengths from vertebral centra for males and females at the first and second ring marks. Growth of anglerfish was expresse d as TLt=1130 (1-e(-0.080(t+0.401))) (t less than or equal to 8) for m ales and TLt=1547(1-e(-0.064(t+0.345))) (t less than or equal to 13) f or females using the back-calculated total lengths. Our results sugges ted females grow faster and live longer than males.
