How the Role of Diet Fed to Bass (Micropterus salmoides) and Cichlids (Oreochromis Mossambicus) Affects Crayfish (Orconectes virilis) Behavior
The goal of this study is to demonstrate the role of predator diet on detection of predatory threats by prey in the aquatic environment. Previous studies have shown that multiple prey species can detect stimuli, specifically chemical cues, and distinguish between predator conspecifics and heterospecifics. Chemical cues will be used instead of visual, auditory, or mechanical cues because chemical signals are a primary modality within aquatic systems (Chivers and Mirza 2001). Evidence suggests that alarm cues from conspecifics are perceived as more threatening than heterospecifics independent of diet (Weissburg et al. 2016; Chivers and Mirza 2001). In this study, we will show how crayfish (Orconectes virilis) respond to either bass (natural predator) odor or cichlid’s (non-natural predator) odor as a result of the diet regime of the predator.
