Table I. Reproductive phases of individual male tripletail (n = 122) captured in 2009 and 2010 near Jekyll Island, GA, USA. All males in this study in the regressing phase were spawning capable but were not undergoing active spermatogenesis. GE = germinal epithelium.
Table II. Reproductive phases of individual female tripletail (n = 102) captured in 2009 and 2010 near Jekyll Island, GA, USA.
Figure 1. Tripletail sampling location near Jekyll Island, GA, USA. Inset shows a map of the southeast United States with the Jekyll Island area indicated by the arrow. Each point on the map indicates that one or more tripletail were captured at that location from March to August 2009 and 2010. 
Figure 2. Non-linear regression of sexually mature female tripletail in 50-mm length bins captured near Jekyll Island, GA, USA from March to August 2009 and 2010. Closed data points represent actual cumulative percent maturity of females, whereas males are represented by the open data points. The dashed line denotes the length (459 mm) at which 50% of female tripletail are mature. The dotted line represents the minimum size limit (457 mm) currently enforced by the Georgia Department of Natural Resources. Non-linear regression models for males were unable to converge and therefore were unable to be modeled; however, only one male captured in this study was classified as immature. 
Figure 3. Non-linear regression of sexually mature female and male tripletail by age class captured near Jekyll Island, GA, USA from March to August 2009 and 2010. Closed data points represent actual cumulative percent maturity of females; males are represented by the open data points. The dotted line denotes the age at which 50% of males (0.55 years) and females (1.17 years) are mature. 
Figure 4. Mean gonadosomatic index values for (A) female (n = 101) and (B) male (n = 116) tripletail captured near Jekyll Island, GA, USA from March to August 2009 and 2010. Error bars represent 95% confidence intervals. Directory: jennings jennings -> The North Atlantic Oscillation: implications for freshwater systems in Ireland Download 279.04 Kb.
