Effect of Allium sativum on the aggressive behavior of male Betta splendens


Amala Shaju, Anne Rebecca A

Allium sativum (Garlic) extract was administered to aquarium fish Betta splendens (Siamese fighting fish) and the effect of the extract on the aggressive behavior of male Betta splendens was assessed based on the following characteristics like duration of avoidance, duration of lateral display, duration of extreme fight and number of opercular flaring. The fish had shown significant reduction in the aggressive behavior after exposing them in Allium sativum extract of different concentrations (1mL, 2mL, 3mL and 4mL) for 3 hours prior to the experimental observations. The characters were observed for 20 minutes and the duration of avoidance was increased from 0mL concentration of Allium sativum extract (10.28±0.04mins) to 4mL concentration (20.00±0.00). Whereas, duration of lateral display showed significant reduction from 0mL concentration of Allum sativum (8.32±0.01mins) to 4mL concentration (0.00±0.00). Similarly duration of extreme fight was also reduced from 0mL concentration (1.41±0.01mins) to 4mL concentration (0.00±0.00). Number of opercular flaring, which is the most distinctive character to measure the aggression of Betta splendens was also significantly reduced from 0mL concentration (21.75±0.96) to 4mL concentration (4.25±0.96). Allium sativum has a stimulatory effect on the brain serotonin level of male Betta splendens which reduced the aggression of the fish.
