The corresponding organic No levels were , , , 63 and 103 NIT;; respectively. The Kjeldahl method is subject to error in sea water (probably at least 10 percent) so that the absolute values have little meaning. However, relative changes are evident and organic No increases with time. The inorganic values reported in gi'ou])s four and five possibly increased during distillation by some dissociation of the âNHo group present in the buffer molecule. The organic values have been corrected for the amounts of tris-buffer present and therefore reflect increases in organic wastes. Figure 2 shows that tris-buffer decreased the rate of pH decline and at the same time markedly increased the time to 50 percent mortality. The group of fishes held at an initial pH of (group five, black squares, Figures 2 and 3) showed a fold increase in the time to 50 percent mortality compared to the control group (group two, black circles, Figures 2 and 3). The groups which lived the longest died at the highest pll. This seems to be a result of prolonged exposure to low pll or high COo concentrations. All death pll values are quite low. It is very x^robable that the majority of marine species exposed to similar conditions would have died at higher pll levels. F. parvipinnis is a euryhaline form fre- quenting habitats in which pH and COo must vary widely. 350-| 325- 300 275 250 225 ^ 200 Q.
