do you herd fish?
The Physical Fish Herding Project
If fish could be herded, it would help in their farming, capture, and enhancement. This research addresses fish herding for the purpose of getting fish up past dams, so that fish populations might survive. The only natural models of fish herding available are of humpback whales and porpoises. The whales surround fish with an air bubble curtains that concentrate the fish into one small area, then the whales surface through the school middle with their mouths open and eat well.
Our research follows this whale design school of thought. We have observed in our research with trout, salmon, hitch and other fish that that fish not only shy away from bubble curtains as in the anchovy from the whale, but in many other cases fish both individuals and schools are attracted to the bubbles for cover, play, and curiosity. We are using all these modes of interaction along with multiple moving air curtains to herd the fish.
