This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured physical details of this fast-moving fish. "Multi-rotor unmanned aerial systems won't replace shipboard surveys or the reliance on manned aircraft to cover a large area," said Mike Jech, an acoustics researcher at the Northeast Fisheries Science Center in Woods Hole, Massachusetts and lead author of the study. Saltwater fish are categorized based on the marine environment they live in. Both fish availability and perception biases introduced by observers can affect results. Results from the APH-22 study were published in March 2020 in the Journal of Unmanned Vehicle Systems. Most carnivore saltwater fish will not eat algae even if they are starving.
