Bomb dating and age validation using the spines of spiny dogfish (,),roduce interpretable vertebral growth bands. Here we report the first application of bomb radiocarbon as an age validation method based on date-specific incorporation into spine enamel. Our results indicate that the dorsal spines of spiny dogfish, ., recorded and preserved a bomb radiocarbon pulse i

Validated age and growth of the sandbar shark, , (Nardo 1827) in the waters off Western Australia,recapture data. Growth curves were derived from consensus counts of growth bands from the vertebrae of 238 individuals ranging in size between 47 and 154 cm fork length (FL). The annual periodicity of growth band formation was validated using vertebrae from tagged sharks, which were injected with ox

AVID

Analysis of variability in vertebral morphology and growth ring counts in two Carcharhinid sharks,s, . (. = 10) and . (. = 11). Five sequential vertebrae were removed from the cervical region, above the branchial chamber and posterior to the chondrocrainium, and thoracic region, below the first dorsal fin. Dorsal-ventral height, medial-lateral breadth, and caudal-cranial length were measured for

Age and growth studies of chondrichthyan fishes: the need for consistency in terminology, verificat estimates from chondrichthyan calcified structures, especially edge and marginal increment analyses; and (3) the functions used to produce and describe growth parameters, stressing the incorporation of size at birth (. .) and multiple functions to characterize growth characteristics, age at maturity and longevity.
