This work is based on biotests being experimented at sea organisms - fish Serranus scriba. We were studying the activity of the mentioned fish in sublethal concentrations of organochloric pesticide - lindane. Besides the classic biotests, we used some new methods for neurotoxic testing that include the influence of this pesticide on circadian activity of fish as well as the variations in obtaining the positive conditioned reflexive responses. The results of these experiments show that this kind of fish reacts at the subtile changes of toxic concentration with the change of quality and rhythm in its conditioned reflexive reactions, that appeared earlier than other global signs of intoxication.
