A Comparative Study of Habitat Value for the Juvenile Blue Crab (Callinectes sapidus) Provided by Off-bottom Oyster Farming in the Northern Gulf of Mexico

Stewart, Eric (2015-01-07)

In the northern Gulf of Mexico (nGOM), the quality and quantity of nursery habitat available for juvenile utilization is the most critical limiting factor affecting local populations of the blue crab, Callinectes sapidus. ...

Developing a Long-Term Monitoring Protocol for the Pygmy Sculpin (Cottus paulus), a Spring Dwelling Imperiled Species

Matechik, Christopher (2014-05-14)

Long-term monitoring protocols require adequate levels of precision in order to detect temporal changes in abundance or density. However, the ability to detect changes can be reduced by sampling variation, seasonal ...

Differences in oxygen consumption and critical oxygen levels of five stream fishes

Hartline, Nathan (2013-11-08)

Metabolic rate represents an integrated measure of a fish’s physiology, particularly as it relates to stressors. A metric that is commonly used to determine the hypoxia tolerance of fishes is the determination of animal ...

Evaluation of a fluorescent dye assay to assess glochidial health

Mitchell, Kathryn (2016-05-06)

Unionid mussels have the greatest diversity in North America but have suffered high extinction and imperilment rates due to habitat loss, fragmentation, and deterioration. Unionid mussels have a parasitic larval stage ...

Novel experimental technique to confirm fish hosts for “large river mussels”

Hart, Michael (2014-07-02)

Unionid mussels are declining in North America. The larval stage (glochidium) represents a life-history bottleneck because glochidia are parasitic and require an appropriate fish host. However, appropriate fish host species ...

Quantitative methods for integrating instream biological monitoring data into aquatic natural resource management decision making

Kennedy, Kathryn D. Mickett (2015-03-20)

Freshwater aquatic resource management is fraught with challenges, as managers of multiple-use, highly diverse systems must frequently make management decisions with limitations including unclear management objectives and ...

Shifting Relationships Between Crayfish and Symbiotic Worms in Surface Water and Subterranean Environments

Ames, Catlin (2013-08-22)

Branchiobdellidans are small annelids (Clitellata) that have neutral, positive, and negative effects on stream crayfishes. Host effects are context dependent, with positive effects (increased survivorship and growth) ...

Using sonar habitat mapping and GIS analyses to identify freshwater mussel habitat and estimate population size of a federally endangered freshwater mussel species, Amblema neislerii, in the Apalachicola River, FL

Smit, Reuben (2014-05-02)

Identification and quantification of freshwater mussel habitat in large turbid rivers is challenging. Sonar habitat mapping offers a low cost and time efficient means to identify and quantify benthic habitats over large ...
