| Abstract: | Age, gonad state, gut content, and length-weight relationships were analyzed for oyster toadfish, Opsanus tau (Linnaeus), caught in 1978–1980 at Hilton Head, South Carolina, Toadfish Tournaments. Examination of the otoliths revealed ages that ranged from < 1 to 8 yr, with a median age of 3 yr. Fish were sexually mature between years 2 to 7. Combined length-weight data provided a linear regression line value of WL = 4.9e0.017L; the age-weight relationship was Wt = 26.5e0.52t. An unexploited fishery is suggested by the data. |
