Towable cage for studies of smoltification in Atlantic salmon

The floating towable cage described in this report was used successfully to hold and transport Atlantic salmon (Salmo salar) in estuarine waters. These rugged and versatile cages, constructed from readily available, inexpensive materials, were tied singly and in clusters to floating docks in fresh and brackish water, where they withstood strong currents, winds, floods, and tides for 2.5 months without visible damage.
