520 3 a| Lane snapper, Lutjanus synagris, otoliths were collected from headboat and commercial fisheries landings and from fishery independent sampling along the east coast of Florida from 1997 to 2003 (n = 1414). Specimens ranging in size from 25 mm to 547 millimeters total length (mm TL) were measured and assigned ages. Ninety - eight percent of sectioned otoliths could be aged. Fishery-independent samples were used to clarify formation of the first annulus and to complement the fishery dependent data set for other analyses. Marginal increment analysis established that rings formed annually, primarily in June. The oldest fish encountered was 12 years and 406 mm TL. The east coast of Florida was separated into north and south regions with the dividing line at Ft. Pierce. The range in age and size for back-calculated total lengths were by regions, ages 2-10 years for north Florida were 153-437 mm TL, while south Florida fish for ages 1-12 years were back-calculated to 131-397 mm TL. The von Bertalanffy growth equation for north Florida was Lt = 443.9 (1-e -0.30(t + 0.82) and Lt = 311.4 (1-e -0.63(t + 0.61) for south Florida. The length and weight relationship was determined using additional headboat data from 1998-2003 (n = 5837). The relationship was significantly different between regions: W = 9.50 x 10-5 TL (R2 = 0.93, n = 2939) for north Florida, and W = 6.94 x 10-5 TL (R2 = 0.81, n = 2898) for south Florida, where W = total weight (grams). Also, lane snapper from north Florida were typically larger at age and reached asymptotic length slower than fish from south Florida.;
