Developmental And Functional Analysis Of Scutes In The Armored Catfish Corydoras Aeneus, Emily Volk Jan 2019

Developmental And Functional Analysis Of Scutes In The Armored Catfish Corydoras Aeneus, Emily Volk

Undergraduate Honors Theses

Fish scales are specialized biological structures of current interest in innovative materials design because of the combination of protective function, flexibility, and light weight they offer. This study presents a developmental and functional investigation of a particular fish scale structure, the scutes (bony external plates) of the armored Bronze Corydoras Catfish (Corydoras aeneus). Scutes in this model fish species were analyzed via three complementary approaches. First, scutes were documented throughout fish development via high-quality microscope images. These images were subsequently used to inform fabrication of synthetic models to characterize the relationship between scute overlap and overall bending stiffness of scute ...


Your Catch Of The Day Could Be Your Catch Next Week: Angler's Interactions With The Trout Populations Of Northeast Colorado, Melissa Merritt Jan 2018

Your Catch Of The Day Could Be Your Catch Next Week: Angler's Interactions With The Trout Populations Of Northeast Colorado, Melissa Merritt

Undergraduate Honors Theses

This research project is an analysis of catch-and-release fishing near Boulder, Colorado. Catch-and-release is a conservation practice, common among anglers, which requires anglers to return fish to the water after capture with no harm done or as little harm as possible. This study focuses on voluntary catch-and-release during fly fishing. The first research question is: What are the conservation effects of catch-and-release angling on healthy trout populations? The methods employed to answer this question involved reviewing past literature and studies on catch-and-release for various trout populations. This review showed that there are remarkable inconsistencies in research methods and results. Further ...


Juvenile Blue Crab (Callinectes Sapidus) Survival In Simulated Seagrass Habitats (Zostera Marina And Ruppia Maritima), Kylie Smith Jan 2017

Juvenile Blue Crab (Callinectes Sapidus) Survival In Simulated Seagrass Habitats (Zostera Marina And Ruppia Maritima), Kylie Smith

Undergraduate Honors Theses

Anthropogenic increases in global temperatures and nutrient loads are expected to reduce juvenile blue crab (Callinectes sapidus) survival in the Chesapeake Bay. These factors change habitat composition which can affect juvenile invertebrates and fishes that are dependent on these habitats. Eelgrass (Zostera marina) is declining due to rising water temperatures and increased nutrient loading, while widgeon grass (Ruppia maritima) can tolerate higher temperatures. An indoor mesocosm experiment was designed to test the suitability of Zostera and Ruppia as protective nursery habitats compared to sand. Artificial seagrass plots were placed in flow-through tanks. Juvenile blue crabs were tethered, and adult blue ...


The Consumption Of Lionfish As A Control Of An Invasive Species In Bermuda, Alaire Davis Jan 2016

The Consumption Of Lionfish As A Control Of An Invasive Species In Bermuda, Alaire Davis

Undergraduate Honors Theses

This research focuses on how lionfish are affecting the waters of the Caribbean Sea and western Atlantic Ocean, and the practices in place to control the lionfish invasion. The presence of lionfish in these areas is a significant problem because of the detrimental effect they have on coral reef ecosystems. Countries in the Atlantic that are directly dependent on underwater ecosystems for their economy, and the global underwater environment in general, are at risk. My research aimed to determine if consuming lionfish can be a viable way of reducing lionfish in Bermuda. I approached this question by surveying three categories ...


Smooth Hammerhead Target Fishing And By-Catch In Puerto López, Ecuador: Trends In Catch And Recommendations For Mitigation, Lauren E. Degeorge Jan 2014

Smooth Hammerhead Target Fishing And By-Catch In Puerto López, Ecuador: Trends In Catch And Recommendations For Mitigation, Lauren E. Degeorge

Undergraduate Honors Theses

Sharks have not historically been considered a valuable resource but, with the increase in demand for their fins, shark catch numbers have risen dramatically and many shark populations are suffering. It is difficult to know the extent of the problem because there is a lack of information about sharks and shark catch is vastly under-reported. The smooth hammerhead shark (Sphyrna zygaena) is valuable in the shark fin market for its eight, large fins and is frequently landed at the Puerto López fish market in Ecuador. EquililbrioAzul is a marine conservation organization that has been keeping track of shark catch in ...
