Abstract
Information on the fishing ground location and effective effort plays important roles in fishery management. Using this information, we could conduct the analysis of fishery spatial management and effort standardization. A global positioning system (GPS) tracker and a GPS logger have been well developed and allow a wide range of applications in many sectors because the sensors and logger have become more affordable with good resolution and high accuracy. In this study, we intend to use the GPS tracker in capture fishery application to obtain details about the fishing ground location and as an effective method for artisanal grouper fishery. Eight GPS tracers were installed on 10 boats for grouper fishery in Saleh Bay, West Nusa Tenggara Province, Indonesia. On the basis of the GPS position, we could plot their fishing ground and also measure the distance for each trip and the time required for each fishing operation. Results of this study showed that the fishing grounds of grouper fishing boats were 5-10 nautical miles from the fishing landing port and mostly at the western part of Saleh Bay. In general, speargun and hook and line (troll line and handline) fishers had different fishing grounds, where speargun fishers tend to fish within a marine protected area (MPA) and hook and line fishers tend to fish in the southern (outside) part of the MPA. From the results of this study, a similar analysis method could be utilized in Banyuwangi sardine fishery for the science and technology research partnership for sustainable developments project (SATREPS).
