Autumn was the end of a busy field season and multiple laboratory projects for the Contaminants of Emerging Concern (CEC) Team. October marked the end of a study examining the effects of CECs on lake sturgeon at streamside rearing facilities, as well as experiments exposing fish and native freshwater mussels to mixtures of CECs to assess adverse effects on health. There is currently little information available regarding how CECs can impact fish and freshwater mussel health, and consequently population size. Findings from this research will fill existing knowledge gaps and potentially help inform best management practices for populations affected by CECs in the Great Lakes Basin. But the work hasn’t stopped just because the field season is complete. Over the next several months data resulting from this research will be analyzed and prepared for publication in reports and peer-reviewed journals. The CEC Team will also be ramping up outreach efforts in the near future in order to disseminate research findings to broad audiences and to help inform management decisions as they relate to CECs.
