Thorley, J.L. and Dalgarno, S. (2018) Quesnel Lake Exploitation Analysis 2017. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/942646731.

Background

Quesnel Lake supports a recreational fishery for large Bull Trout, Lake Trout and Rainbow Trout. To provide information on the natural and fishing mortality, trout were caught by angling and tagged with acoustic transmitters and/or reward tags.

Background

Horse Lake supports a recreational fishery for stocked Rainbow Trout and Kokanee and wild Lake Trout. To provide information on the natural and fishing mortality, Lake Trout were caught by angling and tagged with acoustic transmitters and/or reward tags.

Lower Columbia River Fish Population Indexing Analysis 2016

The suggested citation for this analytic report is:

Thorley, J.L. and Muir, C.D. (2017) Lower Columbia River Fish Population Indexing Analysis 2016. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/589633601.

Background

In the mid 1990s BC Hydro began operating Hugh L. Keenleyside (HLK) Dam to reduce dewatering of Mountain Whitefish and Rainbow Trout eggs.

The primary goal of the Lower Columbia River Fish Population Indexing program is to answer two key management questions:

What are the abundance, growth rate, survival rate, body condition, age distribution, and spatial distribution of subadult and adult Whitefish, Rainbow Trout, and Walleye in the Lower Columbia River?

What is the effect of inter-annual variability in the Whitefish and Rainbow Trout flow regimes on the abundance, growth rate, survival rate, body condition, and spatial distribution of subadult and adult Whitefish, Rainbow Trout, and Walleye in the Lower Columbia River?

The inter-annual variability in the Whitefish and Rainbow Trout flow regimes was quantified in terms of the percent egg dewatering as greater flow variability is associated with more egg stranding.

Thorley, J.L. (2016) Quesnel Lake Large Trout Natural and Fishing Mortality Analysis 2015. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/1323057218.

Background

Quesnel Lake supports recreational fisheries for large Bull Trout, Lake Trout and Rainbow Trout. To provide information on the natural and fishing of large trout, acoustic receivers were deployed at key locations in Quesnel Lake. Large trout were caught by angling and tagged with acoustic transmitters and reward tags.
