OverviewAI-generated summary
Rebecca Lochmann's research focuses on aquaculture nutrition, with a particular emphasis on developing sustainable fish feed and understanding the nutritional requirements of commercially important fish species. Her work investigates the impact of different dietary components on fish growth, health, and body composition. Recent publications explore the effects of plant-based diets and novel lipid sources on channel catfish (Ictalurus punctatus) and hybrid striped bass (Morone chrysops ♂× Morone saxatilis ♀), examining nutrient retention, growth performance, and physiological responses.
Lochmann's research also delves into specific micronutrient requirements, such as iron, in channel catfish diets. Her studies have identified how different forms of iron affect anemia prevention, as well as potential negative impacts on liver and intestine health. Furthermore, her work extends to understanding growth parameters and fatty acid composition in largemouth bass (Micropterus salmoides salmoides and Micropterus nigricans) under varying temperature and feeding conditions. She also investigates the integration of aquaculture with other agricultural systems, such as in coupled aquaponic systems, examining the production and mineral composition of crops like okra (Abelmoschus esculentus) when raised with Nile tilapia (Oreochromis niloticus).
With an h-index of 24 and nearly 2,000 citations across more than 80 publications, Lochmann is recognized as a highly cited researcher and a Fellow of the ARA Academy. Her laboratory at the University of Arkansas at Pine Bluff actively collaborates with colleagues, including Grace Ramena, Michele Jones, M. Thompson, and Hannah Knuckles, all from the same institution.

ARA Academy 2017 ARA Fellow
Dr. Lochmann's team investigates alternative dietary protein and lipid sources, prebiotics and probiotics, and other feed additives affecting growth, health, product quality, and reproductive performance in aquaculture species including baitfish, catfish, largemouth bass, hybrid striped bass, and tilapia. Research includes cost-effectiveness assessments related to production profitability.
Policy Impact
Drives cost-effective aquaculture innovations that support Arkansas's position as a leading U.S. aquaculture producer, directly benefiting the state's farm economy.
