Abstrak: Penelitian kondisi ekologik fitoplankton dan zooplankton di perairan P. Simeulue, Aceh Barat, dilakukan tergabung di dalam « Penelitian Sumberdaya Hayati Laut Dan Habitatnya Di Perairan Pulau Simeulue, Nangro Aceh Darussalam » pada bulan Juni 2006. Kelimpahan sel-sel fitoplankton dan individu zooplankton di perairan ini ternyata umumnya relative rendah. Di perairan ini terlihat kelimpahan fitoplankton tertinggi terjadi di perairan di depan kota Sinabung (st. 11) yaitu mencapai nilai 23,8x103 sel/m3. Kelimpahan fitoplankton terendah tampak di depan Teluk Simeulue (st. 8) hanya mencapai 2,3x103 sel/m3. Kelimpahan rata-rata di seluruh perairan ini mencapai 7,1x103 sel/m3. Sebaliknya kelimpahan individu zooplankton tertinggi terjadi di depan Teluk Simeulue (st. 8), yang mencapai nilai 2,9 x 102 indiv./m3. Kelimpahan zooplankton paling rendah terjadi di perairan di depan kota Sinabung (st. 11) yang mencapai nilai 0,2x102 indiv./m3. Kelimpahan rata-rata individu zooplankton di perairan ini mencapai nilai 1,2x102 indiv./m3.

Kata kunci: fitoplankton, individu zooplankton, P. Simeulue, dan kelimpahan.


Abstract: The research of Ecological Conditions of Phytoplankton and Zooplankton in the Simeulue Island Water, West Aceh, were carried out included together in the research of « Sumberdaya Hayati » and their habitat in the Simeulue Island Water, Nangro Aceh Darussalam, in June 2006. In facts the abundances of phytoplankton cells and zooplankton individues in the water were generally found relatively were in low concentrations. In the water, it was shown that the phytoplankton abundance were reached relatively the highest concentration were occurred in the water in front of Sinabung Town (st. 11) that reached the number of 23.8x103 sel/m3, while relatively the lowest number was shown in front of Simeulue Strait (st. 8) that was reached the number only 2.3 x 103 cells/m3. The average number of phytoplankton in the whole area was 7.1 x 103 cells/m3. In contrarily, the abundance of zooplankton were reached relatively the highest concentration was occurred in the water in front of Simeulue Strait (st. 8) that reached 2.9 x 102 indiv./m3, while the lowest concentration was shown in front of Sinabung town (st. 11) that reached the number of 0.2 x 102 indiv./m3. The average number of individues of zooplankton abundance in the water were reached the number of 1.2 x 102 indiv./m3.

Keywords: phytoplankton, zooplankton individues, Simeulue Island, and abundance.
