Assessment and methods development of dyed feeds for the evaluation of toxic fish bait consumption
Recently there has been an increased removal effort of adult Grass Carp Ctenopharyngodon idella from the Lake Erie Basin through traditional capture methods (Herbst et al. 2021). Use of chemical control tools such as a general or ingestible pesticide to support this removal effort has been identified as a potential management option (Robinson et al. 2021).
One method to increase species selectivity of a control chemical is to incorporate it into a bait designed for the target species. Although there are many methods to determine ingestion and absorption of aquafeeds, none exist that are simple, cost-effective, quantitative, and can mark fish with a long-lasting, visible indicator. The goal of this project is to develop a method that will allow researches to quickly and quantitatively evaluate the consumption of bait formulations being designed for select species.
