Abstract:
Plankton research is critical in the aquaculture as the plankton serve as live food for
the fish cultured. This study is focused on the plankton composition and abundance in
different type of aquaculture pond. Different types of pond hold different fish stage;
larvae and juvenile stage. This study was done at Kampung Pengkalan Gelap, Setiu
from May to July 2010. Sample of water from four different type of pond is collected
using hand net with 20 µm mesh size were brought back to lab for plankton analysis.
The sample is preserved using 4% buffered formalin for zooplankton and Lugol's
iodine for phytoplankton. The pond is juvenile pond, fish larvae pond, plankton
cultured pond and control pond. The phytoplankton and zooplankton were identified
and counted using Lackeys method for phytoplankton and zooplankton is using the
formula to calculate the density. To know what species of plankton is abundance in
pond is important. For phytoplankton, genus Chaetoceros
is the most abundance
where it presents in all ponds. The higher density of phytoplankton recorded in fish
larvae pond with the value 3.34x10
cells/L.
