  Stock assessment of christian crabs (Charybdis feriatus, Linnaeus, 1758) in San Miguel bay 

  Nieves, Plutomeo M.; Olfindo, Nelson R.; Macale, Aldrin Mel (Aquaculture Department, Southeast Asian Fisheries Development Center, 2015)

  Assessment of the status of swimming crab fisheries in San Miguel Bay with focus on Christian or Crucifix crab, Charybdis feriatus, was undertaken from November 2011 to January 2013. An analytical length-based fish stock assessment was employed using the FISAT (version 1.2.2). A total of 7,679 length frequencies (3,612 C. feriatus and 4,067 Portunus pelagicus) were used in the analysis. About 15 and 14 percent gravid females were harvested monthly for both species that may contribute to recruitment overfishing. Population parameters showed exploitation rate (E) for P. pelagicus and C. feriatus exceeded the optimum exploitation (E0.5) implying excessive fishing effort and heavily exploited stocks. Size at maturity of C. feriatus and P. pelagicus in San Miguel Bay is 8.3 cm and 8.5 cm, respectively. Doable options for resources conservation and management strategies are proposed and supported by local government units (LGUs) including the Integrated Fisheries and Aquatic Resource Management Council.

  Motoh, Hiroshi (Carcinological Society of Japan, 1983)

  The author intends to illustrate and describe the indigenous devices traditionally used to capture crabs including the constructions and the operational manners. Also the present writing is hoped to play a role in disseminating the record of the unique devices among local Philippine people and continued use of them. It may be added that the biological significance related to these devices may worth to be recorded.
