In order to characterize the distribution pattern of rotifers Brachionus spp. in North Sulawesi, sample collections have been conducted at four locations, two at east coast and other two at west coast of North Sulawesi peninsula, which are connected to Maluku and Sulawesi Seas, respectively. At each location, a 40 p.m mesh size plankton net with a 0.3 m opening diameter was horizontally towed at three sites to represent coastal water, estuary and brachkiswater pond. Sampling periods were in January and August 2005 to represent west monsoon and east monsoon, respectively. Each sampling was performed twice a day during high and low tide. Some environmental factors were also measured in situ during the sampling. Three species of Brachionus were found during the survey, Brachionus rotundiformis, B. caudatus and B. quadridentatus. Their abundances were significantly different, both between locations and sampling sites. However, among the similar habitat such as between Manembo-nembo and Minanga brachkishwater ponds, B. rotundiforms abundance was not significantly different. This species was the most abundant compared to the other two species, in average 1984,4 ind/m3, while the other species was as low as 26,1 ind/m3 and 212,9 ind/m3 for B. caudatus and B. quadridentatus, respectively. The abundance of rotifers in northern areas connected to Molluccas Sea is higher compared to those in the southern areas connected to Sulawesi Sea. Distribution of B. caudatus is very similar to those of B. rotundiformis, while B. quadridentatus appears to have its specific pattern. Results of this study suggest that the abundance and species composition of the rotifers reflect trophic status of the aquatic ecosystem in the area. It is still awaiting future studies to elaborate the impacts of the trophic gradients in horizontal distribution of rotifers. Therefore, it is necessary to conduct a long term monitoring with emphasis on the structure of rotifer assemblages in a variety of sites subjected to environmental perturbations, including anthropogenic contaminant inputs.

Dari 96 ekor ayam buras yang diperoleh dari Kotamadya Medan dan sekitamya untuk keperluan survai cacing parasitik ternyata tiga ekor (3,125%) diantaranya mengandung cacing pita kecil di dalam usus halus dalam jumlah yang sangat banyak. Cacing- cacing tersebut berwarna putih, agak transparan, berukuran panjang 8-20 mm, rataan 15.4± 3.31 mm (SD). Skoleks berukuran panjang 135-180 um dengan rataan 143 ± 12.19 um, lebar 120-150 um dengan rataan 130± 9.91 um tanpa kait-kait. Lubang genital unilateral, terletak diantara anterior dengan pertengahan segmen. Kantung sirus relatif besar dibanding dengan segmen. Di dalam segmen gravid terdapat kantung-kantung telur. Telur berdiameter 45 mm, berbentuk bundar seperti bola, diselubungi tiga membran dan sudah mengandung larva saat akan dikeluarkan. Dari ciri-ciri tersebut disimpulkan cacing ini termasuk jenis Hymenolepis cantaniana. Ini merupakan laporan penemuan pertama kali jenis cacing pita tersebut pada ayam (buras) di Indonesia.

Dari 96 ekor sampel ayam buras yang diperoleh dari Kotamadya Medan dan sekitarnya untuk keperluan survai cacing parasitik ditemukan 42 ekor (43,75%) diantaranya mengandung cacing Gongylonema ingluvicola di dalam temboloknya. Cacing ini ditemukan pada sampel ayam buras dari semua lokasi yang disurvai dengan rataan derajat infeksi 14 ekor cacing per ayam. Cacing ini membentuk rangkaian lipatan-lipatan pada mukosa yang agak teratur dan seragam, berupa terowongan yang melingkar-lingkar dan mengakibatkan penebalan mukosa tembolok ke arah lumen. Panjang cacing jantan antara 16 - 21 mm dengan rataan 19 mm dan diameter 225 - 255 µm; panjang cacing betina antara 31 - 54 mm dengan rataan 4 1,6 mm dan diameter 3 15 - 345 µm. Cacing jantan mempmyai ale (pelebaran kutikula ke arah lateral serupa sayap) pada sisi kiri dan kanan yang tidak simetris. Ale kiri disokong oleh 7 buah papila (tonjolan kutikula berbentuk duri) sedangkan ale kanan disokong oleh buah 5 papila. Pada cacing betina, vulvanya terletak di bagian posterior tubuh.

The research aims to find out the existence and the most dominant rotifera in coastal territorial waters and estuaries in North Sulawesi, and their relationship with temperature, salinity, turbidity, dissolved oxygen, and nutrients. The research was conducted in Manembo-nembo, Minanga, Wori, and Tumpaan. Identification of rotifera revealed three species of rotifera from all locations, i.e. Brachionus rotundiformis, Brachionus caudatus, and Brachionus quadridentatus, with abundance value of 198 Joice R.T.S.L.

The research was conducted in Manembo-nembo, Minanga, Wori, and Tumpaan. Identification of rotifera revealed three species of rotifera from all locations, i.e. Brachionus rotundiformis, Brachionus caudatus, and Brachionus quadridentatus, with abundance value of 1984.4 ind/m3; 26.1 ind/m3; and 212.9 ind/m3 respectively. Result of analysis indicates that abundance of those three rotifera are significantly different both between locations and sampling sites. The abundance of B. rotundiformis in Manembo-nembo and Minanga is higher compared to those in Wori and Tumpaan. The abundance of B. caudatus is higher in Manembo-nembo and Minanga compared to those in Wori and Tumpaan. The abundance of B. quadridentatus is also different from the other two species, the abundance is sifnificantly different in Minanga compared to those in Manembo-nembo and Tumpaan, but is not significantly different with those from Wori. The highest abundance of B. rotundiformis was found in brackishwater pond and the lowest was in coastal area. Key words: bioecology, rotifera, coastal water, estuary
