USING DISCERNMENT WHEN INTERPRETING DATA FOR FISH TREATED WITH STREPTOMYCIN SULFATE

In order to study the effectiveness of the lateral line system and better understand its function, researchers have used the chemical streptomycin sulfate to presumably ablate lateral line function in fish and amphibians. A 10mM solution of streptomycin in seawater has been an accepted concentration for no specified duration of time. This study utilized similar methodology to ablate the lateral line system in juvenile Walleye Pollock. To ensure the streptomycin did not affect overall motivation of the fish to feed, streptomycin treated pollock were also observed feeding in light conditions. There was a decrease in feeding for treated pollock in the dark; however, a similar decrease was noted in light conditions, when pollock would presumably use their sight rather than their lateral line system. This suggested that streptomycin sulfate might have toxicological effects that affect the overall motivation of fish to feed and possibly perform other behavioral tasks. Research that does not consider these possible effects may be misleading and this study indicated the importance of performing thorough control experiments for full consideration of all possible effects of streptomycin.
