The Division of Fish and Wildlife is planning to conduct a study of mercury in river otters. Previous studies have found elevated mercury concentrations in fish from various locations throughout the state. Laboratory studies have shown that high levels of mercury in the diet of fish-eating wildlife can cause decreased reproduction. However, we have virtually no information on mercury concentrations New Jersey’s river otters. In order to gather this information we are seeking the cooperation of trappers during the coming river otter season.

Successful permit applicants will receive instructions for submitting skinned otter carcasses, for which a $5 reward will be offered. In the past, the assistance of New Jersey’s hunters and trappers has been invaluable in collecting information that the Division uses to protect and manage the state’s wildlife resources. We look forward to working with you on this study.
