And the zebrafish said: I like biomimetic robots

In this paper, we study the feasibility of modulating fish behavior using bioinspired underwater robotics. We experimentally study the response of zebrafish (Danio rerio) to a robotic fish of varying size, color pattern, and motility in a dichotomous preference test. In this canonical experimental protocol, focal fish residing in the central compartment of a three-chambered test tank are confronted with various robots juxtaposed with the empty compartment and their position is observed over time to measure preference. A total of six experimental conditions is studied to isolate the effect of different robot design elements and provide general techniques for fostering the attraction of zebrafish.
