Background

The Mica Tailrace Fish Indexing Study is a four year program to estimate the effects of the addition of two new turbines (Mica 5 and 6) on the ichyofauna and thermal regime in the 2.5 km of the Columbia River downstream of Mica Dam. A single year of fish indexing data (2008) was also available from a previous program. As per the Terms of Reference (TOR) the relative abundance, condition and spatial distribution of the fish populations was assessed. In addition, changes in the species evenness were also estimated.

Lower Columbia River Fish Population Indexing Analysis 2013

The suggested citation for this analytic report is:

Thorley, J.L. (2014) Lower Columbia River Fish Population Indexing Analysis 2013. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/252359126.

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 LCR?

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 LCR?

Kootenay Lake Exploitation Study 2013

Thorley, J.L. (2014) Kootenay Lake Exploitation Study 2013. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/1088509848.

Background

The Kootenay Lake Exploitation Study is a multi-year fish tagging program to estimate the proportion of large rainbow and bull trout that are caught by anglers versus die of natural causes on Kootenay Lake.
