Description In connection with the prawn studies of the Sub-station, routine observations on the
surface salinity, temperature, oxygen etc., were conducted regularly in the Cochin
backwater for the past few years. A paper on the plankton and its relationship
with salinity of the Bunder canal at Narakkal connected with the backwater has been
published (George, 1958). For this study, observations along the canal were made
throughout during the high water. A doubt then arose whether it would give a true
picture of the conditions of the canal by following only the high waters of each day
since varying amounts of sea water might enter into the backwater and from there
into the canal during the high water, bringing with it planktonic organisms
and salinity conditions which are more marine than what had existed during the low
water. Balakrishnan (1957) while studying the surface salinity of Ernakulam channel
noticed a number of rapid fluctuations which were attributed, to a certain extent, to
the influence of tide. The present work is an attempt to understand the amount of
tidal influence, if any, on the salinity of the backwater, at the various heights of the
tide and to see whether two different conditions, one during high and the other
during low water, exist in the area.
