KELIMPAHAN ROTIFERA Brachionus spp. DI SULAWESI UTARA
ABSTRACT: This research is
aimed to find out the existence of rotifers in coastal territorial water and
estuaries in North Sulawesi, the most dominant type of rotifers, and their
relationship with some environmental parameters such as temperature, salinity,
turbidity, dissolved oxygen, and nutrients. The research was conducted in
several locations, during different seasons and tide. The identification of
rotifers revealed three types from all locations, they are B. rotundiformis, B.
caudatus, B. quadridentatus, with abundance value of 1985 ind/m3; 27 ind/m3;
and 214 ind/m3 respectively. B. rotundiformis was more abundance compared to
other two types. The result indicates that abundance of those three rotifers are
significantly different both between locations and sampling sites. To compare
the abundance of those three types of rotifers in all locations shows that the
abundance of B. rotundiformis in Manembonembo is not significantly different
from the same species taken from Minanga, and the abundance of rotifers in
Manembo-nembo and Minanga is higher compared to those in Wori and Tumpaan.
