The collections were made by vertical haul using NORPAC net of mesh size 140 m. Planktonic chaetognaths constituted 2.93%, 5.60%. 2.23% and 3.66% of total zooplankton population during cruises I, II, III and IV, respectively. Highest mean abundance of chaetognaths was recorded during cruise II (pre-SW monsoon) (mean of 724430 ind. m-3) and lowest during cruise III (post SW monsoon) (mean of 18932 ind. m-3). Two-way ANOVA showed no significant difference (p>0.05) in abundance of planktonic chaetognaths between the cruises but significant difference (p CP - IRAN IN - LG - eng PB - JOC PG - 43 PT - Research/ Original/ Regular Article YR - 2010
