“…To address this, we developed GoFish, a user-friendly platform for dynamic, fully-automated behavioural experiments on fish or other aquatic organisms. Our platform is inspired by present day behavioural, cognitive and neuroscience experiments that rely on open-source, community based, DIY-type solutions for running and developing new experimental paradigms, as well as for processing and analysing the resulting data streams (Akam et al, 2022;Aoki et al, 2015;Bishop et al, 2022;Buscher et al, 2020;Devarakonda et al, 2016;Geissmann et al, 2017;Guilbeault et al, 2021;Gurley, 2019;Kane et al, 2020;Kapanaiah et al, 2021;Mathis et al, 2018;Oh et al, 2017;O'Leary et al, 2018;Pineño, 2014;Siegle et al, 2017;Swanson et al, 2021;Walter & Couzin, 2021). Briefly, our system allows for the display of stimuli on a computer screen placed outside but adjacent to a tank, the detection of the subject's location in real-time through an overhanging camera, the programming of contingencies between fish movements and the delivery of food rewards, and the automatic recording of data in analysable format.…”
