Buoyancy Compensation by Atlantic Salmon ( Salmo salar ) Smolts Tagged Internally with Dummy Telemetry Transmitters
Negative buoyancy was induced in Atlantic salmon (Salmo salar) smolts by insertion of dummy telemetry tags (4.0 g in water) into the stomach. Buoyancy adjustment by means of swimbladder volume change was determined in tagged and untagged (control) smolts either allowed or denied access to the water...
