The distribution of surface temperature and salinity in the waters of the Arabian Sea along the Bombay and Saurashtra coasts is presented and discussed.
The two factors show seasonal trends associated with the prevalence of the two monsoons, South-West and North-East.
In general, waters North of 20° N. latitude have a higher salinity and lower temperature than waters South of it.
The variations in salinity and temperature indicate the possibility of seasonal upwelling in the coastal waters between 20° and 21° N. latitude and to a less extent upto 22° N. latitude during the period December to February.
It is suggested that these mixing phenomena may be of great importance in determining the fertility of these waters.

The large-scale fish mortality that occurred in the Madurai Mariamman Teppakulam in November, 1955, is discussed in detail. The tank had been accumulating all kinds of organic debris, including periodic pollution by sewage. Consequently the waters have been rendered inimical to life contained in it. The meteorological conditions that prevailed during the period has culminated in the upwelling of all poisonous gases from the tank bottom proving fatal to fish life.
