International Journal of Undergraduate Research and Creative Activities
Evaluating abiotic environmental factors that influence growth of sportfish is key to understanding population dynamics and making appropriate management decisions. This is especially true in river systems where primary and secondary productivity can vary across temporal and spatial scales. In this study, we assessed fish responses to ambient nutrient levels (total nitrogen and total phosphorus) using growth rates determined from age-1 Channel Catfish, Ictalurus punctatus, in Platte River, Nebraska. Water quality and growth data were collected from sites across the central and lower Platte River from 2007 to 2013. We analyzed Platte River water quality data to find yearly average …
