Resumo(s)

Studies assessing fish spatial behaviour are essential to better understand the performance of marine protected areas. However, few studies have focused on the fine-scale movements related to reproduction, a key feature in a population’s perpetuation. Knowledge of movements modulated by reproduction is particularly important since migrations towards spawning grounds may increase the vulnerability to threats if these occur outside protected areas. Further, reproductive behavioural polymorphism is widely understudied but may affect reproductive success. In this work, we used acoustic telemetry to study a harvested fish, Diplodus sargus, within a small no-take zone in Portugal.
