The tiger shark (Galeocerdo cuvier) is believed to be a fast-growing shark that has shown regional variation in growth. Vertebrae samples were taken from 124 tiger sharks (60 females, 38 males, 26 of unknown sex) caught in Western Australia (WA) from 1994 to 1998. Samples were aged using standard vertebral ageing techniques, and the data were used to create length-at-age curves. Dahl-Lee back-calculation was used because of the low number of small juveniles (<140-cm fork length, FL) captured. Males (n = 38) were found to have an age range of 3–21 years and a length range of 145–306 cm FL; females (n = 60) had an age range of 2–31 years and a length range of 118–361 cm FL. A Bayesian multi-model approach to growth-curve fitting was used, and the von Bertalanffy model provided the best fit to back-calculated data on the basis of deviance information criterion (DIC). Parameter estimates for the combined-sex back-calculated data were as follows: asymptotic length (L_∞) = 372 cm FL; growth-completion coefficient (k) = 0.067 year^–1; and length-at-birth (L₀) = 65.8 cm FL. Growth of WA tiger sharks was slower than that of tiger sharks from most other regions, but similar to that observed on the eastern coast of Australia.

虎鲨（Galeocerdo cuvier）被认为是一种快速增长的鲨鱼，在生长过程中表现出区域差异。从1994年至1998年从西澳大利亚州（WA）捕获的124头虎鲨（60例雌性，38例雄性，26例不明性别）中提取椎骨样本。年龄曲线。之所以使用Dahl-Lee反向计算，是因为捕获的小少年数量少（叉长<140 cm，FL）。男性（n  = 38）被发现的年龄范围是3-21岁，长度范围是145-306 cm FL。女性（ñ = 60）的年龄范围为2–31岁，长度范围为118–361 cm FL。使用贝叶斯多模型方法进行增长曲线拟合，并且基于偏差信息标准（DIC），von Bertalanffy模型为反算数据提供了最佳拟合。用于组合性别逆计算数据的参数估计如下：渐近长度（大号_∞）=372厘米FL; 增长完成系数（k）= 0.067年^–1；出生时的长度（L ₀）= 65.8 cm FL。西澳大利亚州虎鲨的生长速度比其他大多数地区的虎鲨慢，但与澳大利亚东海岸的虎鲨相似。
