Carcharhinus falciformis is listed as near threatened on the IUCN red list. They are one of most heavily fished tropical shark species and are incidentally caught in significant numbers by long-line and purse seine fishing operations. Serious sustainability concerns from overfishing have emerged in recent years throughout their distribution, particularly within the Central West Pacific. Despite dominating local catch, life history information is not available for silky sharks in this region, impeding sound fisheries management. Age and growth estimates from length-at-age data (n= 527) were produced for the silky shark Carcharhinus falciformis from Papua New Guinea. Age estimates were produced from vertebral analysis conducted on samples collected by an on-board observer program operating in the Papua New Guinea long line fishery. A multi-model approach incorporating AIC was used to estimate growth rates which included the von Bertalanffy, logistic and Gompertz growth functions as candidate growth models. Estimates of length and age-at- maturity were also produced.
