Pigment matters: Behavior and lateralization of albino and pigmented fish (Bronze Corydoras) in aquaculture

Original language description

Animal welfare science recognizes fish as sentient beings capable of experiencing pain, stress, and various emotions. As social interactions and mutual relationships are essential for fish welfare, the social environment in aquacultures is important for fish welfare. Pigmentation influences fish social behavior, e.g., communication and/or shoaling behavior. We investigated how pigmentation and shoal phenotypic composition affect locomotor activity in relation to feeding, exploratory behavior, sheltering and lateralization in holding tanks and Ymazes in pigmented and albino Bronze Corydoras (Corydoras aeneus). The fish were divided into three treatment groups: pigm only, alb only, and mix groups. Each group comprised 12 shoals, with a total of 288 fish distributed across 36 shoals, each containing eight individuals. The study revealed behavioral differences between fish with pigmented and albino phenotypes, both within and among shoals. For both phenotypes, an increase in locomotor activity before feeding was followed by a decrease in activity after food consumption, indicating an anticipatory response and a shift from foraging to postfeeding behavior. In the mixed shoals, pigmented fish exhibited greater activity and sheltering behavior than albino fish. Both albino and pigmented fish showed lateralization toward the right arm of the Y-maze; however, in the mixed shoals, the preference for the right arm was not significant. Albino fish reached the shelter at the end of the Y-maze more often; however, in the mixed shoals, albino fish maintained their success rate in exploring the maze, while pigmented fish showed an increased success rate. We emphasize the significance of considering phenotypic variation and shoal composition when evaluating fish behavior and welfare. Such insights can inform the management of practices in aquaculture and ornamental breeding to ensure optimal fish welfare and enhance their overall quality of life.
