Motility and viability of rainbow trout and trout spermatozoa exposed to insecticides ENOLOFOS 50 and liquid OWADOFOSSO were studied. Constant contents of the toxicants were used in solutions of various salinity (from 0 to 18%o). The used concentrations of both insecticides, when applied in pure water “solution”, caused no significant changes in motility of the spermatozoa. On the other hand, the insecticides applied at all the salinities used had toxic effects on the spermatozoa, the effects increasing visibly with salinity. The results obtained allow to conclude that the insecticides used may be more harmful in the sea than in fresh waters.
