ABSTRACT
The whiteleg shrimp Litopenaeus vannamei is one of the most cultured penaeid species
in Indonesia. However, a good standard of environment such as water quality characteristics for
aquaculture must be met to avoid commercial loss. The aims of the study were to analyze the water
quality in the aquaculture pond and their relationship with plankton dynamics and specific growth rate
(SGR) of L. vannamei. A descriptive method with the analysis on the primary and the secondary data
was performed to determine the effect of water quality on the abundance of plankton and the SGR of
the whiteleg shrimp in the intensive pond. The results showed that the plankton abundance indicates
that the pond is eutrophic and the water quality affects the plankton abundance. The regression analysis
demonstrated that the abundance of phytoplankton was influenced (from the highest to the lowest
regression coefficient) by the salinity (94.7%), orthophosphate (94.1%), temperature (91.8 %), CO2
(80.3%), turbidity (66.1%), total organic matter (TOM, 35.2%) and ammonia (16.4%). On the other hand,
the zooplankton abundance was significantly affected by the temperature (44.7%), turbidity (41.9%),
dissolved oxygen (DO, 26.2%), salinity (14.9%) and TOM (7.2%). The parameters of water quality
that affect SGR L. vannamei were ammonia (87.3%), zooplankton abundance (81.2%), TOM (74.9%),
DO (63.1%), pH (48.9%), temperature (41%), turbidity (25.8%), salinity (19.4%), orthophosphate (13.2%), and phytoplankton abundance (1.1%). The PCA analyses performed the relation between plankton
abundance and water quality parameters.
