Abstract
The information of meiofauna abundance from Indonesia mangrove is still scarce. This
research aimed to know the abundance of meiofauna from mangrove area in Basilam Baru
village. Samples were collected using corer from sediment that dominated four different
mangrove vegetations i.e. Rhizopora apiculata, Xylocarpus granatum, sonneratia alba and Avicennia alba. A total of 4144 meiofauna which consisted of Copepoda, Nematoda, Nemertina, Olygochaeta, Ostracoda, Polichaeta and Thermosbaenacea were found in this study. The total of meiofauna abundance that found in mangrove area of Basilam Baru
village was 682,03 ind/10cm2. The average abundance of meiofauna within the four
different mangrove vegetations was significantly different (P<0,05). The most dominant meiofauna was Nematode followed by Copepode. The highest abundance of meiofauna was found around Avicennia alba and the lowest abundance was found around Xylocarpus
granatum.
