Abstract
As the fishing operations becomes more of a problem due to widespread and un-selective exploitation of fish stocks, there is an urgent need to leverage technology advancement to aid conservation and management efforts. We present and demonstrate how TREKfish technology can be used to meet this demand in this study. The TREKfish is designed to track a vessel^s position by recording its position at regular intervals, and it generates data and information such as the vessel^s position over time, from departure (leaving port), transit to the fishing grounds, and while carrying out fishing operations, and returning to port, allowing the overall footprint of the vessel to be traced from start to finish. In this study we installed TREKfish in vessels that catch Blue Swimming Crab. The distribution, abundance, and amount of catch per unit of effort (CPUE) can be mapped and computed based on the accumulation of fishing activity records. This CPUE information is critical for sustainable fisheries management. It will also be able to assist in understanding the state of targeted fish stocks (i.e. Blue Swimming Crab) and identifying conservation or limited areas in the fishing grounds.
