sing the otoliths, the age and growth characteristics of Lophius.litulon in north of the East China Sea and south of the Yellow Sea were primarily studied from march, 2007 to may, 2009. The results showed that the age group of L.litulon was from 1 to 5 a, and they were mainly composed by young fishes which ranged f rom 1 to 2 years old. The relationship between body length( L ) and weight( W) was W=1.55897×10-5L3.10865; the relationship between the radius of otolith and body length was L=244.1R-210.6; the growth pattern can be described by von Bertalanffy equation as Lt = 749.9 [ 1 – e -0.349 ( t + 0.256 ) ], Wt = 13496.4 [ 1 - e – 0.349 ( t + 0.256) ] 3.10865. The max age was 8.377 a, and the age of growth turning point was 2.99 a, and the corresponding body length and body weight were 508.8mm and 4038.7 g respectively. For the purpose of resource conservation, fishing of L.litulon should be limited to the individuals with body length of 500 mm below.
