“…Social segregation refers to the formation of different groups, for instance, by age, sex, and/or size 66 – 68 . Although this can be the case for the S. umbra , which seems to aggregate according to age 69 , the two main distribution centers at RNMCB, do not seem to reflect social segregation since all individuals were mature adults and their size did not significantly affect our results. Thus, we believe that the observed distribution of S. umbra was driven by habitat segregation.…”

“…1.5 km, this relatively isolated distribution of the population might be explained by habitat availability and discontinuity at small space scales 18 , 31 , 44 . The S. umbra typically prefers rocky areas 15 , 70 , where they can hide in burrows and caves in the center of their home range and perform excursions in the surrounding area 37 , 69 . The presence of an intermediate zone of sand and seagrass meadows between the two distribution areas might therefore act as barriers limiting the movements of S. umbra , as observed for other species 49 , 71 .…”

The brown meagre (Sciaena umbra) is an endangered species, which requires specific protection measures to ensure its conservation. These measures need to be informed by high-quality scientific knowledge on their space use patterns. Here, we used acoustic telemetry to assess its seasonal movement patterns and habitat use within a marine protected area (MPA). Our results suggested that S. umbra is a highly sedentary species (home range < 1.0 km2) and, therefore, the MPA is extensive enough to protect the local population. Their population was discretely distributed in two main areas within the MPA, which was likely a result of habitat segregation and density-dependent movements. The temporal variability of their movements further uncovered when and where spawning occurs (mainly, but probably not only, in the fully protected area in June) and indicated that spillover of this species is limited but still possible. Overall, we highlight the importance of MPAs in the recovery of S. umbra, we advocate the need to perpetuate the current national fishing bans and extend it to other countries in the Mediterranean region, and we emphasize that considering the fine-scale movements of S. umbra in future management actions is key to achieving a successful recovery of their populations.
