Tintinnids are one of the ubiquitous microzooplankton in marine waters and are recognized as indicator species of water quality. This study is a survey of the composition, diversity, and abundance of tintinnids along 8 stations in Masinlocā??Oyon Bay (MOB). Tintinnids were collected through plankton net with 20 Ī¼m mesh size on July 2017. Temperature, salinity, pH, DO and TDS of the water were measured using YSI 6600 meter. The nine identified tintinnid species in this study are first records for the MOB. The warm water species Helicostomella longa (Brandt, 1906) dominated the tintinnid assemblage. Diversity range of 0-1.9 Hā?? indicates that MOB is moderate to the heavily polluted bay. Anthropogenic activities and industrialization such as mining, port construction, oil spills, power plant thermal discharge and fish cages might affect the species diversity index of the bay. Multivariate analysis created a cluster of the stations (2-5) within Marine Protected Ares (MPAs) and a separate cluster of the stations (1, 6-7) far from MPAs. The station within the power plantā??s outfall had the lowest abundance and diversity. Higher diversity indices were recorded at the station within MPAs. The results can support the notion that MPAs are promoting resilience in the MOB. The tintinnid variation in this current work showed the uniqueness and diversity of the MOBā??s marine environment. The present study is the first bay wide assessment of Masinloc-Oyon Bay using biological and environmental parameters.
