Estimating Daily Growth Of Age-0 Channel Catfish In A Free-Flowing, Commercially Exploited Midwestern River, Kaleb B. Wood
Estimating Daily Growth Of Age-0 Channel Catfish In A Free-Flowing, Commercially Exploited Midwestern River, Kaleb B. Wood
Masters Theses
The larval stage in fishes is an important stage in the life history, as their survival dictates the ability of the population to sustain itself as an adult population. While there is a plethora of information available for juvenile and adult life stages of Channel Catfish (Ictalurus punctatus), very little is understood about their larval life stage. This study sought to determine overall density, growth rates, and size structure of cohorts of age-0 Channel Catfish during a study year on the Wabash River. In 2018, I sampled age-0 Channel Catfish using a benthic trawl from May to September. …
Population Demographics Of Channel Catfish In The Lower Wabash River, Valerie J. Thompson
Population Demographics Of Channel Catfish In The Lower Wabash River, Valerie J. Thompson
Masters Theses
Inland fisheries are experiencing increasing demands due to anthropogenic stressors, especially within large river systems that support both recreational and commercial fisheries. Riverine species are sensitive to habitat degradation, species introductions, and exploitation, so continued monitoring and management of these communities are vital to maintain abundance and diversity within these systems. The North American catfish family, Ictaluridae, supports both recreational and commercial fisheries throughout the United States. Channel Catfish Ictalurus punctatus are heavily studied and managed compared to other sport catfishes in this family because of their economic and ecological significance. One important Channel Catfish fishery exists in the lower …
Evaluation And Demographic Response Of The Shovelnose Sturgeon Commercial Caviar Fishery In The Wabash River, Jessica L. Thornton
Evaluation And Demographic Response Of The Shovelnose Sturgeon Commercial Caviar Fishery In The Wabash River, Jessica L. Thornton
Masters Theses
Shovelnose sturgeon (Scaphirhynchus platorynchus Rafinesque) are considered one of the last commercially viable options for sturgeon roe harvest. Due to the collapse of several marine sturgeon fisheries and the Similarity of Appearances provision which protect shovelnose sturgeon in only a part of their range, the caviar fishery in the Wabash River remains an important point of supply for this lucrative natural resource. In this thesis, I presented an evaluation of the shovelnose sturgeon commercial caviar fishery in the Wabash River. More specifically, I described the demographic response of this population to continued exploitation over a 10-year period. Additionally, I …
Diel And Seasonal Patterns Of Channel Catfish Movement And Habitat Use In The Lower Wabash River, Hanna Gibbs Kruckman
Diel And Seasonal Patterns Of Channel Catfish Movement And Habitat Use In The Lower Wabash River, Hanna Gibbs Kruckman
Masters Theses
Channel catfish Ictalurus punctatus are commonly found throughout the Mississippi River basin and support commercial and recreational fisheries in many large river systems. Understanding population demographics as well as movement patterns and habitat usage can provide a more holistic approach to species management and conservation. Within a 16-km stretch of the lower Wabash River, 27 channel catfish were implanted with acoustic transmitters to monitor fine scale movement and habitat use from September 2014 through April 2016. Channel catfish were located using active tracking during two types of tracking events. Site tracking occurred only during daylight hours and diel tracking monitored …
Demographics And Parasites Of Spotted Bass In The Wabash River, Evan C. Boone
Demographics And Parasites Of Spotted Bass In The Wabash River, Evan C. Boone
Masters Theses
Spotted Bass Micropterus punctulatus Rafinesque are a popular sport fish primarily found in the streams and reservoirs of the south. The Wabash River, a large tributary of the Ohio River, contains a naturally reproducing population on the northern boundary of their range. Currently, the lower Wabash River is monitored using two different sampling designs, the Long Term Electrofishing Program monitors community assemblages using stratified random sampling whereas the Illinois Department of Natural Resources uses a fixed sampling design. Due to the wide distribution but low abundance of Spotted Bass throughout this drainage, captures from each design were compared to assess …

Ecological Games In Space And Time: The Distribution And Abundance Of Antarctic Krill And Penguins, Suzanne H. Alonzo, Paul V. Switzer, Marc Mangel
Ecological Games In Space And Time: The Distribution And Abundance Of Antarctic Krill And Penguins, Suzanne H. Alonzo, Paul V. Switzer, Marc Mangel
Paul V. Switzer
The distribution and abundance of organisms are affected by behaviors, such as habitat selection, foraging, and reproduction. These behaviors are driven by interactions within and between species, environmental conditions, and the biology of the species in-volved. Although extensive theoretical work has explored predator–prey dynamics, these models have not considered the impact of behavioral plasticity and life-history trade-offs on predicted patterns. We apply a modeling method that allows the consideration of a spatial, dynamic ecological game between predators and prey using a life-history perspec-tive. As an illustrative example, we model the habitat selection of Antarctic krill and penguins during the time …

Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham
Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham
Masters Theses
Lake Charleston, Illinois was electrofished to determine the status of the largemouth bass (Micropterus salmoides, Lacepede) population after its reconstruction into a pump storage reservoir. The changes observed were an increased rate of growth of the initial year class, increased average growth increment of older bass, and a more abundant bass population. Factors which may have influenced increased growth were decreased turbidity, alkalinity, and increased water level. There is a possibility the increase in water level led to an increase in terrestrial invertebrates as a food source, and increased spawning substrate and cover due to submerged terrestrial vegetation. …
