      Fifty bottom sediment samples of Kakinada Bay have been analysed for their phosphate content with the object of studying the distribution of the different types of phosphates in relation to the mechanical composition, the colour of the sediment and the depth of the bay. It has been found that, the phosphate content of bottom sediments is very low; there is in general an increase in the concentration of total phosphate in northern and western parts of the bay and a decrease of the same in the southern and the eastern parts; the intertidal mud flats are also poorer in phosphates; there is no apparent relationship existing between the mechanical composition and phosphate concentration, or the colour of the sediment and the phosphate concentration and the shallow nature of the bay seems to have no effective controlling influence on the phosphate accumulation. The replenishment of phosphates in the waters from the sediments below does not seem to be appreciable in the case of the Kakinada Bay.
