Per cent nitrogen in the swimbladder gas of bottom dwelling species in relation to measured bottom depth. The full drawn line represents the nitrogen percentage to be expected if the swimbladder nitrogen were in tension equilibrium with the sea water nitrogen ( atm.). The presented points are uncorrected for post mortem increase known to occur (especially in the deep sea specimens) before the samples can be secured. This amounts to as much as 2V& per cent, and the broken line represents this correction. COMPOSITION OF THE SWIMBLADDER GAS AS A FUNCTION OF DEPTH We know from the above determinations that the nitrogen tension throughout the sea water may be taken as atmospheres. If we presume that the nitrogen cannot be chemically secreted into the swimbladder, then we would expect it to enter by simple diffusion mostly through the blood stream. Provided the fish.
