Reactions of Gambusia affinis (Girard) to salt water and metallic chlorides
Abstract
Scope of Study: The study attempted to determine the toxic thresholds for the Gambusia in sea water and in solutions of metallic chlorides . Observations were made to determine if the lethal thresholds were the same for males and females. Concentrations of metallic chlorides from 0.0001 M. to 0.7 M. were employed. Findings and Conclusions: All specimens were aloe to survive in 40 percent solutions of sea water. While all specimens were killed in solutions of 70 percent sea water. The females were much more resistant to the toxic effects of sea water than the males . All metallic chlorides produced lethal effects it the concentration was greater than 0.7 M. The heavier metallic chlorides were more toxic to the Gambusia than the lighter metallic chlorides. The least toxic chloride was lithium and the most lethal chloride was mercury.
