Big Muddy Speaker Series presents:
Minnows to Monsters: Fishes of the Missouri River


Monsters, minnows, sturgeon - oh my! Ever wondered what fish actually live in the river? Dr. Brittany Harried from the Missouri Dept. of Conservation will take you on a journey to peek under the surface at all the fish that call the Missouri River home.
Missouri is home to nearly 250 fish species which range in size from 1.5 inches (pygmy sunfish and least darter) up to 10 feet and 350 pounds (alligator gar). Some of these fishes are also endemic species meaning they can only be found in Missouri. The Missouri River and its tributaries host many of Missouri's fish species which play an important role economically, culturally, and functionally in their ecosystem. Learn about fish diversity in Missouri, which fishes call the Big Muddy their 'home', what roles these species play in the Missouri River, and why we need to conserve and protect our fishes and streams.

This presentation originally took place on November 11th, 2025 at the Riechmann Indoor Pavilion in Stephens Lake Park, Columbia, MO.

Meet Your Presenter

Dr. Brittany Harried
, • RAM Stream Community Ecologist
Brittany Harried is the Coordinator for the Resource Assessment and Monitoring (RAM) Program at the Missouri Department of Conservation (MDC). The RAM Program is a long-term, statewide monitoring program that was founded in the early 2000's and is used to assess the health of Missouri's wadeable streams. This program collects data related to water quality, physical habitat, fish communities, and macroinvertebrate communities which can then be used to calculate health metrics for the streams. Prior to starting at MDC, Brittany was a post doctoral researcher at the University of Missouri where she assessed the thermal ecology of rare stream fish in Missouri and conducted stream surveys to assess populations of bluestripe darters, a species of conservation concern that is endemic to Missouri. Brittany completed her PhD in 2021 from the University of North Texas where she studied functional traits in stream fish and how we can use these traits to predict species responses to changes in their environment. She also has a Masters of Science degree in Biology and a Bachelors of Science degree in Aquatic Biology from the University of Wisconsin - La Crosse. During her graduate degrees, Brittany also taught lab courses in biology, fish diversity and ecology, community ecology, and environmental science.
