Kelimpahan Dan Keanekaragaman Fitoplankton Di Perairan Desa Teluk Lecah Kecamatan Rupat Bengkalis

---

Primary productivity is the rate at which photosynthesis and carbon fixation occur.This research is to find outabundance and diversity of phytoplankton in the waters of Teluk Lecah Village, Rupat Bengkalis District. The method used in this research is a survey method, namely carrying out data collection, documentation and direct observation in the field. Then collect quantitative data obtained from water quality measurements. Phytoplankton samples were analyzed at the Marine Biology Laboratory, Riau University. Next, the data obtained is presented in the form of tables/graphs and discussed descriptively. There were 6 species of phytoplankton foundon watersTeluk Lecah Village, Rupat District, Bengkalis Regency, namely Synedra sp., Dactylococcopsis sp., Nitzschia sp., Tribonema sp., Cylindrotheca sp. and Rhizosolenia sp. The first highest phytoplankton abundance was at station II with an abundance of 16.60 followed by the second highest phytoplankton abundance at station I, namely residential areas, with an abundance of 14.94 Ind/L, while the lowest phytoplankton abundance was at station III, namely at the harbor with an abundance of 9.96 Ind. /L.Species diversity index at stations I and III, H' > 3 means the level of species diversity is high and the water condition is not polluted. At station II, 1 ≤ H' ≤ 3 means a moderate level of species diversity and lightly polluted water conditions. It can be concluded that the H' value still meets the criteria. The species diversity index at all stations, E > 0.5, means the uniformity of organisms is in balance and there is no competition for certain places or food. It can be concluded that the E value also meets the criteria. Species dominance index at all stations, D < 0.5 means there is no dominant species.


Keywords: Abundance, Diversity, Phytoplankton, Teluk Lecah Village.
