抄録

Growth of eight captive ocean sunfish was determined using the individual follow-up method. In rearing periods varying between 140 and 1556 days, all specimens displayed simple linear growth. Using these data with one outlier excluded, initial age was calculated and a von Bertalanffy growth curve was estimated with the following equation;<BR>TLt=318.4× {1-exp [-0.149× (t-0.031) ] }<BR>Our results indicate that all specimens used in this study were in the midst of their growth period and that it takes approximately 20 years for an ocean sunfish to reach 3 meters in total length.
