Abstract

This research was conducted in Tondano Lake North Sulawesi for 3 month from June to August 2007.  The research was aimed to identify species abundance of phytoplankton.  Phytoplankton were collected by using a 40 μm  large plankton net.  Results showed that phytoplankton consisted of 32 genera.   It also indicated that the highest individual abundance was shown by Fragillaria (2903 individuals),  followed by Microspora (2349 individuals), Closterium ( 984 individuals), Zynema (803 individuals), Melosira (770 individuals), and Anabaena (693 individuals) respectively with monthly sampling the highest abundance was on August (4227 individuals), followed by June (3516 individuals), and July (3493 individuals).

Abstract

Mollusks are one of benthic organisms that live on the sea bottom, often on the roots, stems, and leaves of plants. Hydroids (Aglaophenia cupressina), one constituent of coral reef organisms in the waters of Siladen Island, Manado, North Sulawesi, which is also an organism that has stingy nematocysts for divers in the region where they live, is a habitat of mollusks. Hydroids sampling was done by Scuba diving at 5 different depths, reef-flat, 5 m, 10 m, 15 m, and 20 m, respectively. All mollusks specimens were taken to the laboratory for species identification. Results found three species of epibiont mollusks on the hydroids, in which the bigger the hydroid size the larger the volume, and higher number was found. This results from that the mollusks use the hydroids as a shelter from predator attacks, strong currents and waves, and food search.
