Microbial investigation in the water of the Lagoon Amir Kolayeh.
1. Microbiological investigations were carried out to fix the bacterial population of the water of the Lagoon Amir Kolayeh in a wild life reserve district. 2. The total numbers of aerobic heterotrophic microorganisms in the water samples of 23 stations were nearly identical in spring and in winter. In summer they increased and reached a very high maximum in fall. 3. Coliform bacteria showed a similar behaviour, but the ascent in fall was much lower. 4. The increase in summer was found to be due to the seasonal rise of temperature. There was a great nitrification activity. 5. The maxima in fall are the effect of immense flights of birds of passage. There were more coliforms of the fecal type in fall than in spring. 6. Between the stations of the fishing ground and those situated in the outside area, reliable differences could not be secured.
