Notes on the gas content and neutral buoyancy in physostome fish
Abstract
SUNDNES, G. and BRATLAND, P. 1972. Notes on the gas content and neutral buoyancy
in physostome fish. FiskDir. Skr. Ser. HavUnders., 16 : 89-97.
Field and experimental observations from herring (Clupea harengus) and char (Salmo
alpinus) indicate that the swimbladder gas is not only "swallowed" from the atmosphere,
but may also be deposited from the vascular system or tissue around the swimbladder
lumen.
