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, Halmahera
Barat. 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.
Key
words
: phytoplankton, Jailolo, relatioship, and zooplankton.
