摘要: In this study we conditioned fathead minnows (Pimephales promelas) to recognize the odor of a perch (Perca flavescens) by exposing them coupled with minnow alarm cue. We then staged encounters between predator and prey in order assess whether training had any effect on survival prey. tested for presence absence shelter. Our results indicate that fish trained signals predators gained benefit during habitat characteristics influenced fish.
