The Initiative to Protect and Recover Endangered Whale Populations from anthropogenic threats (aka Federal Whales Initiative) was announced on June 22, 2018, by Fisheries and Oceans Canada (DFO), Transport Canada and Environment and Climate Change Canada (ECCC). This 5-year initiative (2018-2023)...

Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were...

This project is part of the Northern Contaminants Program core monitoring and looks at contaminant levels in landlocked Arctic char from lakes in Nunavut over time. Landlocked char are the only top predators in most Canadian high Arctic lakes and, therefore, can serve as a sentinel species for...

This project examined the use of parasites of slimy sculpin (Cottus cognatus) as indicators of water quality in the Athabasca River. Specimens of C. cognatus were sampled from four tributaries to assess patterns of helminth parasite community structure in this fish and to study the composition...

In this study, the chronic effects of two emerging brominated flame retardants, 1,2-bis(2,4,6-tribromophenoxy)ethane(BTBPE) and 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB) were evaluated in diet exposed juvenile rainbow trout(Oncorhynchus mykiss). FIsh uptake was measured after 28-d of...

The objectives of the present study were to evaluate the chronixc effects of 2 BZT‐UVs alone and in a mixture, 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐bis(1‐methyl‐1‐phenylethyl)phenol (UV‐234) and 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐di‐tert‐pentylphenol (UV‐328), in juvenile rainbow trout (Oncorhynchus mykiss)...

The toxicity and modes of action of prioritized flame retardants were evaluated in aquatic organisms. The effects of the organophosphorous-containing flame retardant tris (2-butoxyethyl) phosphate (TBOEP) were measured in Daphnia magna after chronic (21-d) and multigenerational exposure (3...

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated...

The objectives of the fish component of the integrated oil sands monitoring program are to provide the necessary data/information to address key questions related to both environmental health of fish populations and fish health issues that can be used to inform human use and consumption. The...
