Abstract:
Marine wood borer has important role in mangrove forest as decomposer. The diversity, ecology and distribution of marine wood borer in Kalimantan Island which has many mangrove forest areas has comprehensive study was ever carried out. This research aimed to investigate the ecology, biodiversity and distribution of marine wood borer. The locations were at West Kalimantan Indonesia, Sarawak Malaysia and Sabah Malaysia. The locations in West Kalimantan consist of Polaria mangrove forest (PMF) in Mendalok village, Mempawah Regency and Mempawah mangrove forest (MMF) in Pasir village, Mempawah Regency, Setapok Mangrove Park in Setapok village, Kota Singkawang. Meanwhile in Sarawak the location was at Asajaya Mangrove Forest and in Sabah was located in Teluk Murudu Kota Kinabalu. All the Infested log in each mangrove forest area were collected and dismantled. All specimen was collected and identification. The ecology data consist of vegetation, soil characteristics (pH, Corganic and soil texture) and water characteristics (salinity, pH, Biological oxygen demand, and dissolved oxygen and chemical oxygen demand).. The results showed that biodiversity of marine wood borer consist of Teredo navalis, Teredo pocalifer, Teredo tritubulata, Teredo calmani, Teredo medilobata, Teredo siamens, Teredo utriculus, Teredi batiliformais, Teredo dagmarae, Teredo brevis, Teredo dallii, Neoteredo reynei, Bankia caribbea, Bankia fimbriulata, Bankia minima, Bankia setacea, Martesia striata,and Petricola pholadiformis. The marine wood borer consist of three family, Teredinidae, Pholadidae and Lymnoridae. The soil characteristics on C-organic content was 1.75% - 2.39%; pH was 7.59 - 8.50; sand 0.60% - 16.39%; silt 55.65% - 57.41% and clay 43.33% - 43.13%. Water characteristics on salinity was 6.55- 10.5; Dissolved Oxygen was 4.74 - 5.59; pH was 7.31- 8.33; Biological Oxygen Demand was 4.74 mg/l - 8.47 mg/l and Chemical Oxygen Demand was 512.3 mg/l - 600 mg/l . Marine wood borer was degradation the wood by enzymes. The wood which attack by marine wood borer was mostly high on holocellulose and alpha cellulose values. The conclusion of research the marine wood borer diversity in Kalimantan Island was high and distribution was achieved along the West Kalimantan, Sarawak and Sabah. The potential development of use marine wood borer as edible food and other uses was high.
