Whooshh Success Story: Moving Atlantic Salmon in a Recirculating Aquaculture System (RAS)
THE CONSERVATION FUND-FRESHWATER INSTITUTE
The Challenge: Growing fish in land-based tanks presents a major challenge to fish farmers, because the fish need to be moved often as they grow. In many cases, using traditional methods such as brailing and using aqua pumps is not only inefficient and wasteful in terms of water, but such methods can be stressful to the valuable fish.
One such entity, The Conservation Fund-Freshwater Institute (TFI), based in Shepherdstown, West Virginia, wanted to find a better way to move fish gently, using less water. With its reputation as a leader in RAS research, TFI wanted to explore new ideas for moving valuable food fish and broodstock.
The Solution: TFI contacted Whooshh to set up a test of the Whooshh system to move 4 kg fish from a grow-out to a 150 m3 finishing tank. A test system was set up whereby the fish were crowded and encouraged into the Whooshh system. After being “Whooshhed” from the growout tank to the finishing tank in another part of the operation, the fish were observed for six days. All fish survived and the test, which showed that fish could be moved with very little water, was judged a success.
