| description | There is little information on the effect of environmental parameters on the
zooplankton biomass and density in the marine ecosystem. This research added on to
the knowledge as results proposes statistical modeling including aspects of biomass
and density to environmental parameters. The objectives are (i) to determine the
impacts of environmental changes on zooplankton density and biomass in the coastal
water of Pulau Tinggi, Johor, (ii) To determine the community structure and
biodiversity of copepods in the coastal water of Pulau Tinggi Johor, (iii) To apply
multiple linear regression model on the relationship between the copepods and
environmental parameters in the coastal water of Pulau Tinggi. The collected
zooplankton samples were taken to the laboratory of UTHM and further analyzed for
density and biomass of 3 size fractions. Environmental parameters were measured in
situ. Biomass and density of zooplankton were dependent variables while
environmental parameters were independent variables. Zooplankton was classified
into seven taxonomic groups; copepods, larvaceans, chaetognaths, cnidarians,
ctenophores, decapods and polychaetes. The copepods were categorized in to four
orders; Calanoida, Poecilostomatoida, Cyclopoida and Harpacticoida. This included a
total of 54 species, 26 genera and 19 families of copepods. Calanoida was the abundant
group represented by 36 species in our study. The values of diversity index showed
that Pulau Tinggi sea grass bed was considered the moderate diverse ecosystem during
the research period. Results showed that statistical model of small size zooplankton (<
500 μm) is the best model for the zooplankton biomass. Water depth, turbidity, water
current, temperature and salinity were significant variables for small size zooplankton
model. This model could be used for the prediction and estimation of zooplankton
biomass. The Principal component analysis (PCA) showed that environmental
parameters like water current, rainfall, tide, nitrates and rainy days strongly influencing
the biomass and density of copepod. |
