Planktonic Copepods in the Bang Pakong Estuary: Seasonal Changes in the Abundance of Adults, Copepodites and Female with Egg Sacs
Abstract
The community structure of planktonic copepods was studied in the Bang Pakong estuary from Bang Pakong District, Chachoengsao Province to Bangtan District, Prachinburi Province during May and September 2013. Three orders of copepods were found, namely, Order Calanoida, Order Cyclopoida and Order Harpacticoida, with 3 different stages (copepodid larvae, female with egg sacs and adult). In May 2013, the average density was 3,268 ind.m-3 with biovolume range from 85 - 253 µm3 and the average carbon content of the biomass was 44.18 pg C.L-1. Whereas, September 2013, the average density was 528 ind.m-3 with biovolume range from 79 - 98 µm3 and the average carbon content of the biomass was 3.71 pg C.L-1. Key words : copepod, plankton, BangpakongReferences
