Population-Level Responses Of The Mummichog, Fundulus Heteroclitus, To Chronic Nutrient Enrichment In A New England Salt Marsh, Konner Chadwick Lockfield
Population-Level Responses Of The Mummichog, Fundulus Heteroclitus, To Chronic Nutrient Enrichment In A New England Salt Marsh, Konner Chadwick Lockfield
LSU Master's Theses
Mummichog (Fundulus heteroclitus) responses to chronic whole-ecosystem nutrient enrichment were examined near Plum Island Sound, Massachusetts. Dissolved fertilizer was released into replicate salt marsh creeks over 6 growing seasons to simulate agricultural run-off (bottom-up effects). Density, biomass, secondary production, growth rate, and condition factor were estimated in fertilized and reference creeks. Mummichog densities were also used to determine if mummichog growth or health varied with density. Over 7,600 mummichogs were marked and released into the treatment and control areas to measure responses. Over 900 mummichogs were recovered. Mummichog abundance was higher (p = 0.055) in nutrient-enriched creeks than reference creeks …

Development Of A Total Nutrient Treatment System For Alligator And Dairy Parlor Wastewater Using Hydrated Lime And Organic Bacterial Growth Media, Troy Francis Davis
LSU Master's Theses
Over application of phosphorus and the loss of ammonia-nitrogen to runoff and volatilization have resulted in the buildup of phosphorus in agricultural top soils around the world, and especially in the United States. Over the past few decades, raising livestock has trended towards the development of the Confined Animal Feeding Operations (CAFO’s) which produce large volumes of wastes that need to be treated before being land applied. Nutrient treatment systems have typically focused on one nutrient singularly: either nitrogen or phosphorus. In order to develop a total nutrient system a phosphorus and nitrogen system had to be developed and evaluated …
