The testicular part of ovotestis does not get atrophied in higher lengths and the species functions as a regular hermaphrodite throughout. The absolute crop for an individual is estimated to be generally above 5,000 in number. An individual spawns once continuously in a number of batches. Spawning activity appears to reach its height in the size 66-80 mm.

While adults dominated the catches during premonsoon, juveniles were abundant during postmonsoon season. Among the polychaetes, <i>Dendronereis arborifera</i> and <i>Sabellaria cementarium</i> were dominant; December to January being favourable. Bivalves dominated at stations having sediment with medium, fine and very fine fractions. <i>S. cementarium</i> was more in sandy stretches, while <i>D. arborifera</i> favoured regions of fine sand admixed with silt and clay.

At st 1, least disturbed by sewage outfall, salinity was found to be the major limiting factor for the distribution of <i>V. parahaemolyticus</i>. Seawater helped the survival of <i>V. parahaemolyticus</i> during the monsoon season at st 2. At st 3, highly disturbed by wastes from fishery industries, fluctuation of <i>V. parahaemolyticus</i> population was maximum. Monsoon rains played indirectly a major role on the distribution of <i>V. parahaemolyticus</i> in association with plankton through plankton blooms. The study shows that <i>V. parahaemolyticus</i> occurs throughout the year in Cochin Backwaters system.

There is no significant relationship between chl <i>a</i> and either glycollic acid or dissolved carbohydrates in these samples. Page(s): 116-118 1984-09-01T00:00:00Z
