- Behavioral and biochemical effects of benzophenone-3 ingestion in dusky damselfish Stegastes fuscus. de Souza, Jéssica Ferreira Silveira, Mayara Moura Moreira, Ana Luisa Pires Souza, Juliana Alves Costa Ribeiro Martins, Rafael Xavier Farias, Davi da Silva Junior, Francisco Carlos Luchiari, Ana Carolina Animals Benzophenones Water Pollutants, Chemical Behavior, Animal Perciformes Sunscreening Agents Liver Biomarkers Oxybenzone (also known as benzophenone-3 or BP-3) is an organic ultraviolet (UV) filter commonly used in personal care products. BP-3 has been detected in various aquatic environments and is a major concern in reef areas due to their biological richness and vital role in marine ecosystems. This research focused on investigating the effects of BP-3 exposure in dusky damselfish Stegastes fuscus, an endemic species of the Brazilian coast, analyzing behavioral responses, enzymatic biomarkers on encephalon and liver (catalase (CAT), glutathione S-transferase (GST), acetylcholinesterase (AChE), and lactate dehydrogenase (LDH)), and general health indicators (growth rate and hepatosomatic index). Adults of S. fuscus were fed a diet containing BP-3 at concentrations of 10 μg/g food and 20 μg/g food for 44 days, with behavioral tests starting after 30 days of exposure. Light-dark preference, novel tank and aggressiveness tests were conducted. Our results showed that BP-3 exposure decreased health indicators and altered fish behavior, decreasing risk-perception and locomotion, although agonistic behavior remained unaffected. Enzymatic assays revealed changes that varied depending on the tissue analyzed. These findings highlight the potential of BP-3 to impair behavioral and physiological processes in reef fish, emphasizing the need for regulations on UV filters to protect marine ecosystems and reef life.
