Abstract/Description: | The lethal oxygen levels, time to death, total oxygen consumed and the metabolic rates of Panulirus polyphagus (Herbst) are estimated at different salinities, temperatures and oxygen partial pressures after acclimating the lobsters to 17, 32, 39 and 50 ppt at ambient temperatures 22.5, 22.1, 28.1 and 20.1°C, respectively. The incipient lethal salinities are obtained graphically from lethal oxygen levels and time to death at different salinities. The metabolic rate is uniformly high within oxygen independent zone of higher pOj and, in oxygen dependent zone, it is curtailed drastically. Subsequently, the low oxygen partial pressure becomes lethal. As a means of compensation, the metabolic rate in this species decreases at extreme salinities and tends to increase at intermediary salinities. The influence of salinity acclimation and temperature on the metabolic rate is evident. It is suggested that factors other than salinity gradient may also be sought in order to explain the metabolic pattern of this species. |
