Personality has been reported to influence fish response stress. This study aimed assess whether shy and bold display different sensitivities two environmental contaminants: caffeine (CAF) cadmium (Cd). Thus, the sensitivity Cd was compared based on lethal concentrations (LCs). The potential CAF, known alter social behavior locomotor activity of zebrafish, studied using behavioral parameters. Overall, LC values were found for each group: 48 h LC50 4.79 (shy fish) 8.20 mg·L−1 (bold fish); 96...
Caffeine (CAF) has been considered an emerging environmental contaminant and its presence indicator of anthropogenic contamination. This study evaluated the effects concentrations CAF (0, 0.5, 1.5, 300 μg. L-1) on behaviour adult zebrafish (Danio rerio) after 7 days exposure. The components feeding, locomotion, boldness (new tank test), sociability (schooling aggression (mirror test) were analysed. Growth rate weight investigated as complementary measures. (0.5, reduced exploratory in...
This study assessed the effects of two emerging environmental pollutants caffeine (CAF) and metformin (METF) on juvenile zebrafish, raised at 22 °C or 27 ºC, after 96 h exposure. The temperature influenced basal behaviour unexposed juveniles, with higher swimming activity a greater percentage movements well edges observed in fish °C. A significant interaction between CAF was found for behavioural endpoints, but not AChE activity, associated neurotoxicity effects. reduced distance, increased...
Caffeine (CAF) is widely detected in aquatic environments, serving as an indicator of anthropogenic contamination. Its high consumption, and persistence raise environmental concerns. This study was to evaluate the chronic effects terms growth rate, weight, behavior, biochemical parameters concentrations CAF on adult zebrafish. Adult zebrafish were exposed, for 30 d, 0, 0.5, 1.5, 300 µg L
Abstract The chorion acts as a protective barrier, restricting some chemical absorption into the embryo and surrounding fluids. In this sense, larvae may only have direct contact with chemicals after dechorionation. This study aimed to evaluate effects of caffeine (CAF) (0, 13, 20, 44, 67, 100 mg.L −1 ) under different exposure scenarios (embryos or embryos/larvae already hatched) rank stage sensitivity. Thus, three were investigated: from 2 120 hours post fertilization (hpf) (5 days...
