2021 Résumé:
This licence has been issued for the scientific research application No.5339.
The objectives of this project are to collect additional samples for fish health and fish contaminant levels, and to track their status over time to assess ecosystem health and provide an indication of change or stress in the environment.
The research team will be sampling the same species of fish that were investi...

Résumé:
This licence has been issued for the scientific research application No.4830.
Residents of Alberta and NWT communities along Transboundary rivers have voiced concerns such as “are the fish safe to eat?” and “are the fish healthy?” due to the potential cumulative effects of multiple substances, habitat alteration and climate change. There is not any significant historical fish sampling relating ...

2019 Résumé:
This licence has been issued for the scientific research application No.4758.
The 3 year project objective is to conduct underwater eco-physiological monitoring in remote Inuvialuit coastal areas in both summer and winter seasons. This will result in critical benchmark data with emphasis on coastal forage fish species during rapid climate change. Another project off-shoot will be a self-suffici...

Résumé:
The objectives of the research are to conduct an assessment of whitefish diet and contaminants.
Two technicians will collect approximately 60 samples over 7 days at Billy’s Creek in July 2016 and an additional 60 samples at the Hornaday River in August and October 2016. Data will be collected on: species, location, date/time, catch-effort/gear type, length, weight, sex, maturity, otolith, stom...

2011 Résumé:
The objective of the project is to study the health of the fish in the Slave River and at the Slave River Delta. A number of different fish species will be collected to study metals, organic contaminants, gene expression and histology.
The study focuses on the potential stresses that fish in the region are exposed to, by analyzing gene expression (Ribonucleic acid – RNA), metals, and organic co...

Résumé:
The objective of the study is to examine fish health of two small-bodied species in the exposure and reference areas – likely slimy sculpin and ninespine stickleback. A small-bodied fish survey will occur within the exposure area (mouth of Baker Creek) and a reference area (Yellowknife River/Yellowknife Bay).
Small-bodied fish will be captured and measured for weight and fork length, using beac...

2007 Résumé:
The EEM will investigate the cause of differences in fish health that were observed in fish from an area exposed to mine effluent (Jackfish Bay) when compared to fish not exposed to mine effluent (Horseshoe Island Bay). Data will be examined to see what environmental factors are causing the observed effects.
Fish Program:
A small-bodied fish survey will be conducted within one exposure ar...

Résumé:
This research entails a thorough literature search of all the available literature on loche livers and pathology, and an investigation into the occurrence of abnormal loche livers by field sampling and pathology analysis.
A local fisher will be hired from each community (Inuvik, Aklavik, Tsiigehtchic and Fort McPherson) to collect loche. A Gwich’in Renewable Resources Board (GRRB) biologist an...

Résumé:
Research team members will be transported to site via Diavik air charters. Field collections will be conducted from boats provided by Diavik. The different collection gear types will be gillnets, trapnets, and angling. The target sample sizes at each of three sites will be a maximum of 100 lake trout, and 100 whitefish or cisco (to be determined based on catch success rates). Twenty fish of eac...

Résumé:
Winter seismic programs done in the Mackenzie Delta still use dynamite as an energy source under waterbodies not frozen to bottom. Exploding dynamite in or near fisheries waters can potentially impact fish. The main reasons for the study are as follows...
