Notes
We examined the general behavior of male Japanese medaka, Oryzias latipes, after exposed to tributyltin (TBT), polychlorinated biphenyls (PCBs), or a mixture of these chamicals at a concentration of 1μg/g body weight daily for 3 weeks. We analyzed swimming velocity as an indicator of acute toxicity and counted the frequencies of straight swimming and swimming in circles. We also calclated the entropy of the positions of the fish within the experimental chamber. Neither TBT nor PCBs nor their mixture affected the swimming velocity, suggesting that there were no acute toxic effects. However, PCBs exposure increased the frequencies of both straight and circular swimming, suggesting hyperactivity. TBT increased the positional entropy value. Both TBT and PCBs affect the general behavior of mature male medaka, although exposure to the 2 chamicals together has no significant additive behavioral effect.
