Reproduction and spawning habitat of white trevally, Pseudocaranx dentex, in the Azores, central north Atlantic
Reproductive biology and habitat preferences of the white trevally, Pseudocaranx dentex (Carangidae), were studied in the Azores islands, central north Atlantic, to determine the spatial and seasonal dynamics of habitat use of immature and mature fish. The sex ratio was close to 1:1 and fish matured...

description |
Reproductive biology and habitat preferences of the white trevally, Pseudocaranx dentex (Carangidae), were studied in the Azores islands, central north Atlantic, to determine the spatial and seasonal dynamics of habitat use of immature and mature fish. The sex ratio was close to 1:1 and fish matured at about 30 cm fork length. There were no differences in the maturation or length-weight relationships between sexes. The spawning season lasts from June to September. Underwater visual censuses showed that schools of mature individuals preferentially aggregate around the summits of offshore reefs during the spawning season. In contrast, schools of smaller, immature fish use inshore habitats all year round. Our data support the hypothesis that offshore reefs are a preferential spawning habitat of larger white trevally, and most possibly for a number of visitor pelagic predators as well. Inverse relationships between exploitation levels, abundance and size composition at the two different islands suggest that the summer fishery targeting trevally schools around offshore reefs has negatively impacted the population. These findings bring additional ecological and management relevance to offshore reefs. Se realizó un estudio de la biología reproductiva y las preferencias de hábitat del jurel dentón, Pseudocaranx dentex (Carangidae),en las islas Azores, Atlántico norte central, con el objetivo de comprender la dinámica espacial y estacional de individuos inmaduros y maduros en el uso del hábitat. Se observó un sex ratio próximo a 1:1 y una talla de primera madurez de 30 cm longitud de furca, sin diferencias entre sexos respecto a la talla de madurez, ni tampoco en la relación talla-peso. La época de reproducción se prolongó de junio a septiembre. Los muestreos visuales revelaron que durante la época de reproducción los individuos maduros se agregan preferentemente en torno de las coronas de arrecifes en mar abierto, mientras que los cardúmes de individuos inmaduros utilizan los hábitats costeros durante todo el año. Nuestros datos apoyan la hipótesis de que los arrecifes en mar abierto constituyen el hábitat preferente para el desove del jurel dentón y, muy probablemente, de otros predadores pelágicos. Una relación inversa entre los niveles de explotación y la abundancia y talla del jurel dentón en dos islas distintas sugiere que la pesquería de verano del jurel dentón ha afectado negativamente la población. Estos resultados ponen de manifiesto la relevancia, tanto ecológica como para la gestión, de los arrecifes en mar abierto. |
