Photo Album: Rich's Fish Research

Photo Albums

The Aquatic Campus Research Facility is staffed by undergrads in the Department of Natural Resource Ecology and Management and other departments. The research projects dictate the amount of staff needed at any time. The students have an opportunity for hands-on practice of aquaculture techniques and gain fisheries experience. Maintenance of a culture system, fish handling, feeding, collecting data, data management, and water quality are a few of the day to day learning opportunities. For more information about ACRF and the research conducted there, go to http://www.public.iastate.edu/~rclayton/.

These pictures contain images of Rich Clayton’s master’s project. The master’s project consisted of two objectives:

1. HABITUATION PERFORMANCE OF TWO PERCIDS TO FORMULATED FEED UNDER TURBID CULTURE CONDITIONS

To be successful at producing an advanced fingerling walleye (Sander vitreus) or yellow perch (Perca flavescens), pond-run fish have to be habituated to commercial feed. The success of the habituation process depends on many variables, e.g., light source, light duration, temperature, feed, stocking density, and size at harvest. Among these variables, diet contrast/visibility may be the most important for habituation success. The objective of this study was to compare the affect of turbid water (≥ 100 NTU) and clear water culture conditions during the habituation process for these two species.

2. COMPARISON OF SOY AND FISH OIL IN PRACTICAL GROWOUT DIETS FOR WALLEYE

A feeding trial was conducted to compare growth and other performance variables of feed-trained juvenile walleye fed an open-formula diet with 10% soy oil (SOY) replacement for 11.75% menhaden oil in the commercially manufactured walleye grower diet.
