Fisheries

I currently am a fisheries technician for Montana Fish, Wildlife, & Parks with focuses on native species conservation, multi-species management, and applied ecology. I work on a variety of research projects as highlighted here:

Active Projects

Role of Amphibians in Freshwater Fisheries

nohly-toad-1I am currently conducting a literature review on how amphibians interact with and alter freshwater fisheries. Specifically, I am examining how frogs, toads, and salamanders directly and indirectly change the freshwater habitats in which they live and how this might impact fish. The mechanisms by which they do this include grazing and bioturbation, nutrient release, and indirect trophic impacts.

Pallid Sturgeon Food Webs

backwater-wolf-point-3I also work on a project headed by Eric Scholl on the Missouri River. I have been using GIS maps to quantify areas of backwater habitat at different distances from Fort Peck Dam. Additionally, I am examining invertebrate samples from three study sites below the dam to determine how invertebrate communities change due to impoundment.  This is part of a larger study on the food resources of the endangered pallid sturgeon (Scaphirhynchus albus).

Techniques for Determining Food Limitation in Fish Populations

img_0673This is a brand new project I have started with a number of collaborators at Montana State, the U.S. Fish & Wildlife Service, and Idaho State. We will be attempting to determine how field biologists can determine if a fish population is food limited. This is important because food limitation causes population growth of species-of-interest to slow. However, the prevalence of such limitation is unknown and may be more serious than many of us realize. We hope that this project will provide some tool(s) that can shed light on how serious of an issue this is.

Collaborators: Christine Verhille, Kevin Kappenman, Jade Ortiz, and James Paris.

Past Projects

Salmonfly Population Assessment and Emergence Variability

ptdc0031I worked with Heidi Anderson at MSU in the Summer of 2016to assess the population viability of salmonflies (Pteronarcys californica) in the Gallatin and Madison Rivers of southwestern Montana. The large hatches of salmonflies are an important food source for trout and as such bring many anglers to the state. However, some anglers believe hatches are smaller than in the past and it is our mission with this study to find out if that is true or not. We are conducting field work to assess the size of current hatches and stonefly health and comparing these to records from state agencies, private corporations, and individual anglers, guides, and fly shops.
