Descrição
Resumo:The authors determined the age and growth of black seabream Spondyliosoma cantharus (Linnaeus, 1758) caught off the Canary Islands, using the otolith interpretation method. Annual rings are clear in the otolith cross-sections. Two rings, one associated with fast-growing periods (summer) and the other with slow-growing periods (winter) are deposited each year on the otoliths. The specimens ranged from 9.4 cm - 38.6 cm in total length, with ages of 0-9 years. Individuals grew quickly until the third year of life, at which they had reached more than 50 % of their maximum length. The Von Bertalanffy growth curve parameters were: L∞ = 44.09 cm, K = 0.23 year⁻¹, and t0 = -0.34 years. The growth found for this sample of black seabream is very similar to that reported for the species in other regions.
