Biochemical parameters and regurgitation of implanted lead sinkers in largemouth bass, Micropterus salmoides

The original objective of this study was to investigate lead toxicity in largemouth bass (Micropterus salmoides) focusing on the possible implications of ingested lead sinkers (split shots).  We hypothesized that lead in the gastrointestinal tract of a largemouth bass would result in detectable blood lead levels. This study was designed to determine the level and speed at which lead would be absorbed. Commercial lead sinkers were gastrically implanted with the aid of an endoscope and blunt forceps. Within ۱ hour, one of the fish regurgitated the lead sinker and the sinker was immediately re-implanted.  Within ۳ days of the initial procedure, all fish had regurgitated the lead sinkers.  The lead toxicity component of this study could not be completed given that all fish regurgitated the lead shots.  Pre-implantation blood biochemical parameters for largemouth bass are presented.
