Total length and ontogenetic stage of bull sharks in the Gold Coast System.

Mean (±SE) total length (TL) and range of C. leucas of different ontogenetic stages (N = neonate, J = juvenile, SA = subadult, A = adult) caught on rod and line (n = 8), longlines (n = 49) and in gillnets (n = 9) in the upper and lower areas of the Nerang River (natural habitat) and the upper and lower canals (man-made habitat) from January 2006 to December 2008. (RU = river upper, CU = canal upper, RL = river lower, CL = canal lower). Note: rod and line fishing done sporadically across the entire system and gillnets were only deployed in the upper reaches of the Nerang River. Note: A# = a putatively pregnant female 300 cm TL.
