Description of life cycle and mating behavior King threadfin between 70 cm and 100 cm FL may be transitional hermaphrodites (they possess mature male and immature female reproductive tissue, and function as males (Ref. 28736)). However, most king threadfin less than 80 cm FL are males and most more than 95 cm FL are females (Ref. 28737). Transitional king threadfin are most often found in the months of June, July, August and September (Ref. 6390). There is little information on the larvae, although nursery areas are known to be inshore, shallow and of low salinity (Ref. 6390).
