      Initial assessment of the bacterial population of Guimaras waters and soil after the Solar I oil spill 

      C Sombito, G Lio-Po, R Sadaba & R Torreta - Philippine Journal of Natural Sciences, 2009 - University of the Philippines Visayas
      A massive oil spill occurred near the shores of Guimaras Island, Philippines in 11 Aug 2006 caused by the Sunken MT Solar I vessel. The oil spill spread to neighboring towns of Guimaras damaging the marine coastal environment, consequently,causing health and economic problems, particularly, by affecting local fisheries, wildlife and tourism. Hence, this study was conducted to assess, quantify and isolate indigenous bacteria with potential petroleum hydrocarbon-degrading properties that could be used for bioremediation of oil spill contaminated areas in Guimaras and nearby provinces.

      Post-August 2006 oil spill populations of Penaeid shrimp in island and riverine mangroves in Guimaras, central Philippines 

      JH Primavera & JB Abroguena - Philippine Journal of Natural Sciences, 2009 - University of the Philippines Visayas
      To evaluate the impact on biota of the release of arrow up million liters of bunker oil off Guimaras Island, Central Philippines, the penaeid shrimp populations in a protected island mangrove (Tandog) and a riverine mangrove (Sibunag) were surveyed by pocket seine 2-3 months after the August 2006 spill; results are compared to 1993 baseline data. A total of 529 individuals belonging to three penaeid species were collected - Metapenaeus anchistus in Tandog, and Metapenaeus ensis and Penaeus merguiensis in Sibunag. Shrimp densities were significantly higher in Tandog Island in 2006 compared to 1993 but remained similar in the riverine mangrove. This suggests that protection may have a greater impact than the Oil Spill per se because Tandog is part of the protected Taklong National Marine Reserve. In contrast to abundance, shrimp sizes (carapace length) were significantly smaller in 2006 compared to 1993 for both sites.
