April 7, 2017 – The Gibeon Consultancy Services (GCS), headed by Project Leader Dr. Filipina Sotto, presented the initial results of the project entitled Stock Assessment of Blue Swimming Crabs (Portunus pelagicus) in the Visayan Sea, Central Philippines last April 4, 2017 in Allure Hotel and Suites, Mandaue City as part of the ongoing data collection efforts of PACPI for the information-deficient blue crab fishery.
GCS, along with PACPI, hosted the activity that aims to review the progress of the project and deliver initial findings that merit attention of stakeholders. Present in the meeting were representatives of local government of Bantayan, with its town chief Arthur Despi and Madridejos Vice Mayor Salvador de la Fuente.
Over the course of six months, mostly consisting of the wet season, at least 137,000 crabs have been measured in six landing sites in Bantayan Island. The monthly catch trend reported peak production in October to December. Global Positioning System (GPS) coordinates were plotted to identify the exact location of the crab fishing grounds, critical to mapping and coastal zoning. Frequency distribution on sex and gonadal maturity were also obtained.
Initial data on spawning potential ratio of female crabs indicate sustainable fishing pressure in Bantayan Island, with the fishery operating above limit reference point. However, this is limited to the data gathered from August 2016 to February 2017 that falls in the wet season and thus inconclusive of the overall stock health.
GCS is set to complete a year-worth of data by the end of August 2017.
