Spatial Assessment Of Slender Madtom (Noturus Exilis) Diets Within The Illinois Bayou, Brendon K. Mitchell

ATU Research Symposium

The Slender Madtom (Noturus exilis) is a common species with a widespread distribution across the Mississippi River basin. In Arkansas, they can be found in upland rivers/streams in the Arkansas River and White River watershed. Very little data has been collected on the diet of this species and how it varies. We wanted to spatially assess the diet of Slender Madtoms. Slender Madtoms were sampled from 8 sites in the Illinois Bayou watershed using seines and kick nets. Small-scale gastric lavage was used to extract diet data from all individuals. All prey items were preserved and identified to the genus …

Microhabitat Use Of The Highland Darter (Etheostoma Teddyroosevelt) In The Illinois Bayou Watershed Of Arkansas, Colton W. Morris

ATU Research Symposium

Highland Darters (Etheostoma teddyroosevelt) are an Ozark regional endemic species, occurring in the Arkansas River and upper White River systems of Arkansas, Kansas, Oklahoma, and Missouri. There have been very few studies on this species, specifically those that have quantified the habitat use of this species across its range. A new study was needed to fill in the knowledge gap of microhabitat use by the Highland Darter in Arkansas. We wanted to address this knowledge gap by assessing the microhabitat use of this species in the Illinois Bayou watershed in Arkansas. Highland Darters were observed during snorkel surveys at known …

Mussel Communities Of Two Impacted Tributaries In The Arkansas South Central Plains Ecoregion, Jimmy Hall, Seth Drake, Parker Brannon, Savannah Wise

ATU Research Symposium

Anthropogenic influences such as mining and water quality degradation from wastewater effluents and agricultural runoff heavily impact freshwater mussel communities. The South-Central Plains (SCP) Ecoregion in Arkansas contains the Smackover Formation, an area that has been exploited for its oil with high frequency of drilling. In 1922 the Smackover pool in Union County was found and quickly became one of the world's most productive oil sites. Hurricane Creek and Smackover Creek, two tributaries within the Ouachita River basin, have experienced negative impacts from oil exploration and mining. However, to our knowledge, mussel communities in these creeks have not been assessed …

Culled Lionfish Sexual Maturity Over A Four-Year Timespan​, Christina Bland, Jurgen Hauer, Bilal Saleem, Noelle James

Symposium of Student Scholars

Lionfish are invasive in the Atlantic and the Caribbean. Like many other invasive species, they do not have any natural predators in these areas, so their population can grow unchecked. This can decrease the population of native fish species due to lionfish eating to excess. Because of their impact on native species, resource managers have incentivized lionfish hunting. Hunters were paid $6 USD for every pound of lionfish they brought in, so they possibly favored larger lionfish to increase their reward which would lead to an adaptive advantage for fish of smaller sizes. We hypothesized that the lionfish bounty program …

Spatial Assessment Of Aquatic Macroinvertebrate Communities In Tributaries Of Lake Dardanelle, Brendon K. Mitchell

ATU Research Symposium

Aquatic macroinvertebrates are key bioindicators of water/habitat quality and can be used to catch changes in the health of the aquatic systems that they live within. They can also be used to determine a fish community as many fish species require macroinvertebrates as a key part of their diet. These macroinvertebrate communities can change significantly due to varying land-use practices on surrounding riparian area. This is especially in places like Arkansas with lots of agriculture and an increasing population. We assessed 6 tributaries of Lake Dardanelle (Bakers Creek, Shoal Creek, Spadra Creek, Middle Fork Illinois Bayou, Hurricane Creek, and Mill …

Comparison Of Redfin Darter (Etheostoma Whipplei) Diets From Two Spatially Distinct Streams In The Arkansas River Valley, Ben S. Johnson, Ethan H. Dodson

ATU Research Symposium

SPATIOTEMPORAL COMPARISON OF REDFIN DARTER (ETHEOSTOMA WHIPPLEI) DIETS FROM TWO SPATIALLY-DISTINCT STREAMS IN THE ARKANSAS RIVER VALLEY.

Ben S. Johnson1^*, Ethan H. Dodson1,2, and Kyler B. Hecke1, 1Arkansas Tech University, Department of Biological Sciences, Russellville, AR bjohnson69@atu.edu, 2Arkansas Game and Fish Commission, 213 AR-89, Mayflower, AR

Diet-data collection is increasingly difficult for darters, as most methods require the dissection of each specimen and the removal of the digestive tract, which is fatal. As a result, the diets of many darter species have been relatively understudied. The Redfin Darter (Etheostoma whipplei) is one species where …

Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger

Scholars Week

Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

Effects Of Environmental Warming On Clarias Gariepinus Growth And Physiology, Dean Cahill

Capstone Showcase

Fresh water makes up about 0.8% of the Earth’s surface and is home to six percent of its species. Environmental warming is projected to have a significant effect on freshwater systems as the century progresses. They are susceptible to irreversible damage because fresh water availability and temperature is dependent of climate. The Clarias gariepinus, or the African Catfish, is popular among aquaculture in Africa and Asia because of its rapid growth, quick reproduction, and hardiness. The goal of my thesis was to examine the effect of environmental warming and elevated temperatures on the growth and physiology of Clarias gariepinus populations …

Genetic Effect Of Long-Term Angling Pressure On Bluegill Populations In Small Impoundments In Kansas, Morganne Borsh

Three Minute Thesis (3MT®) at UNI

Bluegill (Lepomis macrochirus) is a versatile sport fish popularly fished across Kansas. Over the last decade, Bluegill catch rates have decreased, likely from high angler harvest rates of larger individuals. Large males that exhibit parental care have high growth rates and aggressively defend nests, making them vulnerable to angling. Males that display cuckoldry behavior reach maturity sooner, exhibit slower growth rates, and are generally smaller. The goal of this study is to determine if fisheries-induced evolution resulting from long-term harvest has led to a decline in the growth rate of Bluegill. A total of 100 individuals were sampled from ten …

24andmore: Using Genomics To Improve Walleye (Sander Vitreus) Stocking In Iowa, Rachel Mcdonnell

Three Minute Thesis (3MT®) at UNI

Walleye, Sander vitreus, is one of the top gamefish in Iowa. Due to poor natural reproduction in many Iowa waterbodies, populations are managed with stocking. There are two strains of walleye used to stock Iowa’s inland waters: a river strain derived from the Mississippi River near Genoa, WI and a lake strain derived from Spirit Lake, IA. Each strain may have unique characteristics relative to their environment that could affect the fitness and success of fish stocked. The goal of this study is to understand the genetic diversity within and between each strain to offer stocking guidance to the Iowa …

Investigating The Primary Production Of Bear Lake's Filamentous Algal Blooms, Maycee Page

Student Research Symposium

Filamentous algae blooms(FABs) have been appearing on the Western Shore of Bear Lake within the last couple of years with minimal research done on them. Through YSI meter sampling of light and dark trials of Bear Lake’s Eastern and Western shores and Fluorometer analysis of samples of filamentous algae taken from each site, gross primary production(GPP), net ecosystem production(NEP), and community respiration were calculated. Through graphical analysis between many of the factors that were accounted for, one statistical significance found was between the mass in milligrams of periphyton produced and the gross primary production. The two have a negative correlation …

Characterization Of Stream Quality Of Five Ouachita River Tributaries Utilizing Macrobenthic Species And Fish Populations, Hunter Jones, Brockton Brown

Scholars Day Conference

The Ouachita River originates in west-central Arkansas and exits the state in south-central Arkansas near El Dorado. There are many tributaries that make up the Ouachita River through its Arkansas journey. Five of these tributaries are located in Clark County and were selected for this research. Basic in situ water quality parameters were measured and the riparian zone was characterized at each sample site. The five streams selected were Decieper/Little Deceiper Creek, Mill Creek, DeRoche Creek, Saline Bayou, and Tupelo Creek. Macrobenthic and fish surveys were conducted at two sites (upper and lower) on each creek except Saline Bayou and …

Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright

OHSU-PSU School of Public Health Annual Conference

Infectious hematopoietic necrosis virus (IHNV) is a member of the Rhabdoviridae family and causes infectious hematopoietic necrosis (IHN) disease in many salmonid species during the juvenile or “fry” stage of life. IHNV is endemic to Western North America and occurs in the Columbia River Basin, where Steelhead and Chinook salmon are the most abundant IHNV-vulnerable species. IHNV can cause an epidemic in wild or farmed stocks, killing 90-95 percent of the fish it infects. Transmission is currently understood to occur by direct exposure through the gills, and the virus is shed typically from asymptomatic or clinically ill carrier adults at …

The Effect Of Water Levels On Crayfish Aggression, Emory B. Johnson, Sarah E. Blase

Seaver College Research And Scholarly Achievement Symposium

Crayfish are a very prevalent invasive species that affect many different environments all over the world. Crayfish, specifically Procambarus clarkii, are an invasive species that have currently taken a foothold in the Santa Monica mountains and are threatening native stream species. There is currently a severe drought occurring in the Santa Monica mountains. The drought has been reshaping many aquatic environments by limiting space and resources such as food and shelter. Crayfish are a very aggressive species and adversely affect the habitat they inhabit by rapidly colonizing, burrowing, and their voracious diets. Due to the adverse effects crayfish can have …

Early Nutritional Programming To Enhance The Utilization Of Plant Based Diets In Fish (Largemouth Bass, Micropterus Salmoides), Maya Rene Jackson, Cora Teets, Amit Kumar Yadav, Waldemar Rossi

Posters-at-the-Capitol

Aquaculture has been the fastest growing animal food-producing sector for over half a century. Sustainable aquaculture should include replacement of fish-based feed sources by plant-based ingredients. However, this approach is often impeded by poor growth in carnivorous fish such as largemouth bass (LMB, Micropterus salmoides) fed high levels of plant-based protein. Therefore, our overall goal of the present work was to develop alternative methods of utilizing the plant-based diets (PBD) for sustainable LMB production. When fish is exposed to PBD early in their life, they may accept them more efficiently at later stages (so called Nutritional Programing, NP). Therefore, …
