Keterkaitan Antara Kelimpahan Zooplankton dengan Fitoplankton dan Parameter Fisika-Kimia di Perairan Jailolo, Halmahera Barat
Abstract: Zooplankton have an
important role in water especially in the food chain, this organism is a
consumer I which plays a major role in
bridging the energy transfer from primary producers (phytoplankton) to living
things are at a higher
trophic level (fish
and shrimp). This
research aimed to
analyze the relationship
between the abundance of
zooplankton to phytoplankton
and phisic-chemistry parameters
at Jailolo waters,
HalmaheraBarat. The research
was conducted in
February 2011. The
observation of zooplankton
were taken from 7
stations by filtration method. The result showed that there were 7 genera of 4
(four) groups: Ciliate(1 genus), Crustaceae
(4 genera), Rotifera
(1 genus), and
Sarcodina (1 genus).
Abundance of zooplankton
range from 1,429 - 32,571
cell/m3, the highest on Gufasa and Tuada (32,571 cell/m3) and the lowest on
Bobanehena (1,429 cell/m3). The value
range of zooplankton
biological index were
diversity index (H
') = 0.4506 to
1.5091, equitability index (E) = 0.6356 to 0.9710, and the dominance index (D) = 0 , 2379 to .7222.
There is a close relationship between
the abundance of
zooplankton to phytoplankton
abundance and physico-chemical parameters of
waters, with a
coefficient of determination
(R2) of 0.972
and the regression
equation Y = -
7194397 - 0.0836 phytoplankton + 269630 temperature+ 6195 salinity + 140943 DO
- 128086 pH.
