A re-examination of the age and growth of sand tiger sharks, ,, in the western North Atlantic: the rom 94 to 277 cm total length (TL), and compared to previously published age and growth data. The oldest female and male sand tiger sharks aged in this study were 17 and 15 years of age, respectively. von Bertalanffy growth parameters derived from vertebral length-at-age data are . . = 295.8 cm TL,

Intend

Comparing external and internal dorsal-spine bands to interpret the age and growth of the giant lanal spine were used to obtain age estimates. The number of bands on the external surface of the spine and within the inner dentine layer increased with animal length. Most spines had more bands on the external surface, and the rate of band formation was significantly different between the external su

Do differences in life history exist for blacktip sharks, ,, from the United States South Atlantic areas (eastern Gulf of Mexico and South Atlantic Bight) to address the potential for separate stocks in southeastern US waters. Samples were obtained from fishery-dependent and independent sources. Growth and logistic models were fitted to observed length-at-age and reproductive data, respectively.

Evidence of two-phase growth in elasmobranchs,w of the literature suggests that a two-phase growth model could better describe growth in elasmobranchs. We compare the two-phase growth model (TPGM) with the VBGM for 18 data sets of elasmobranch species, by fitting the models to 36 age-length-at-age data pairs available. The Akaike Information Cr

Two Bayesian methods for estimating parameters of the von Bertalanffy growth equation,a nonlinear regression is used with length-at-age data to recover key life history parameters: .. (asymptotic size), . (the growth coefficient), and .. (a time used to calculate size at age 0). However, age data are often unavailable for many species of interest, which makes the regression impossibl
