A Snapshot Of The Age, Growth, And Reproductive Status Of Gray Triggerfish (Balistes Capriscus, Gmelin 1789) On Three Artificial Reefs In The Northwest Gulf Of Mexico, Adam M. Lee
Theses and Dissertations
Age, growth, and reproductive status of gray triggerfish (Balistes capriscus) were identified from 2015-2016 on artificial reefs in the northwest Gulf of Mexico. Individuals ranged from 232-432 mm fork length with and a mean fork length of 319 mm. Individuals from age 0.2 to 5.2 yrs were observed with a weight to length relationship of Wg = 1.1 x -104 x FL2.7 (r2 = 0.94, n = 112), where FL = fork length (mm) and Wg = weight (g). A von Bertalanffy growth equation of Lt = 326(1 - e - 0.9 (t + 1.71)) was calculated irrespective …
Female Reproductive Impacts Of Dietary Methylmercury In Yellow Perch (Perca Flavescens) And Zebrafish (Danio Rerio), Abigail Rachael Debofsky
Female Reproductive Impacts Of Dietary Methylmercury In Yellow Perch (Perca Flavescens) And Zebrafish (Danio Rerio), Abigail Rachael Debofsky
Theses and Dissertations
This study sought to evaluate the effects of dietary MeHg exposure on female teleost reproduction and phenotypically-anchor gene dysregulation in adult yellow perch (Perca flavescens) and zebrafish (Danio rerio) in order to establish relevant biomarkers relating exposure and subsequent reproductive effects. Yellow perch were used in the study for their socioeconomic importance within the Great Lakes basin, and their significance to the food web. Utilization of zebrafish allowed for a detailed analysis of the molecular effects of MeHg and established its relevance as a model for other fish species. MeHg exposures at environmentally relevant levels were done in zebrafish for …
