Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Towards a downstream passage solution for out-migrating American eel (Anguilla rostrata) on the St. Lawrence River

Aquaculture and Fisheries, 2021
There is a need to develop safe and effective downstream passage for diadromous anguillid eels on large rivers, where the combination of physical screening and bypass structures that is used to protect eel on smaller rivers is infeasible. The Eel Passage
