Thermal Tolerance Of Age-0 Gulf Of Mexico Striped Bass (Morone Saxatilis): Ontogenetic And Genetic Effects, Corey Robert Anderson
Thermal Tolerance Of Age-0 Gulf Of Mexico Striped Bass (Morone Saxatilis): Ontogenetic And Genetic Effects, Corey Robert Anderson
Master's Theses
Striped bass, Morone saxatilis, were historically abundant in the Gulf of Mexico region but were largely extirpated from most Gulf rivers by the early 1960s. Since 1967 hatchery stocking has supported populations in Mississippi rivers and to date there is no evidence of natural reproduction. Intolerance of striped bass to high water temperature is a potential factor negatively impacting Gulf striped bass survival and reproductive fitness, and may be a limiting factor to reintroduction of the species in Mississippi. This work contributed to restoration efforts by establishing molecular tools necessary for genetic monitoring of striped bass restoration, and evaluating …
Feeding Selectivity And Habitat Usage Of Esox Americanus, Scott Richard Clark
Feeding Selectivity And Habitat Usage Of Esox Americanus, Scott Richard Clark
Master's Theses
Patterns of piscine prey selection and habitat usage of Esox americanus were assessed through a series of field and experimental studies. Although few detailed studies exist on the foraging behavior and habitat usage of E. americanus, throughout its range it may be an important trophic component in maintaining fish assemblage structure in many lower order streams. Across 17 sampled streams, the presence of E. americanus among reaches within streams was found to be strongly correlated with increasing levels of habitat complexity. Reaches occupied by E. americanus featured increased amounts of in-stream physical structure, increased variability in stream width and …
