The degree of consistency in the among-individual behavioral differences is usually quantified with the repeatability ( R) score, which describes the proportion of phenotypic variance due to among-individual differences 8. Animal BTs are widespread and have been documented in multiple taxa, including fishes 7. When these individual differences are consistent across time and ecological contexts, individuals reflect distinct “personalities” or behavioral types (BTs) within populations 4, 5, 6. Our work establishes the first baseline of repeatability scores in wild and reared gilthead seabreams, providing novel insight into the behavior of this important commercial species with implications for fisheries and aquaculture.Īnimals differ consistently in several aspects of their behavior between members of the same species, cohort, and sex 1, 2, 3. Phenotypic correlation decomposition between behavioral types revealed two different behavioral syndromes: exploration-sociability and exploration-activity. Reared individuals also presented less variance in their aggressiveness, lacking very aggressive and very tame individuals. We found reared fish to be more aggressive, social and active compared to their wild conspecifics. Results revealed significant repeatability in all five behavior traits, suggesting high consistency of individual behavioral variation across the different axes in this species. We quantified behavioral variation along the five major axes of fish behavioral traits (exploration-avoidance, aggressiveness, sociability, shyness-boldness, and activity) using standardized behavioral tests and a deep learning tracking algorithm for behavioral annotation. In this work, we evaluated the behavioral variation of wild and reared juvenile gilthead seabreams, Sparus aurata, a highly relevant species for aquaculture and fisheries. ![]() Comparing the behavior of wild and reared individuals provides an excellent opportunity to delve into the ecological and evolutionary consequences of BTs. Fish differ consistently in behavior within the same species and population, reflecting distinct behavioral types (BTs).
