Assessing the marine fouling community in a man-made marina at Manila Bay.

Abstract

This study aims to assess the fouling community inhabiting in a man-made marina at Manila Bay. It represents a one-off assessment of fauna at five areas in close proximity using artificial collectors. Fouler collectors were deployed in 5 sampling points for 60 days and collected marine fouling organisms were viewed and identified using taxonomic keys. Results of our study showed that a total of 9725 fouling organisms inhabiting all the 5 sampling points in the man-made marina at Manila Bay were observed. Of these total, 13 families of fouling organisms were identified. About 2 species examined in the area was identified to be an invasive organism. The dominant species present was the Balanus amphitrite. Total abundance of the fouling organisms observed at different sampling points did not show significant differences. A relatively consistent diversity index was observed in all the study areas assessed. This study generates a list of fouling organisms that will be useful in the future evaluation of Manila Bay. Continuous monitoring of these organisms particularly the invasive species is necessary especially as these organisms may bring about consequent risks and damages to aquatic ecosystems.
