Torch light net fishery is one of the considerable scale fisheries in coastal and offshore waters of Taiwan. Because of Taiwan is located in the subtropical zone, and the water masses and marine environmental conditions around the Taiwan are not similar, so the sea areas where the structure of torch light net fisheries have similarities and differences each other, but it has been lacking relevant comparative research all the time. Therefore, this study collect the fishing activity data (including fishing composition, catches amount, fishing position, fishing depth and fishing gear etc.) from sampling boats of torch light net fisheries in northeastern, southwestern and Peng-hu waters of Taiwan, and match up the sea surface image of remote sensing data to confer the fisheries structure of torch light net fisheries in these three areas. In addition, analysis the fishing lights of torch light net fishing boats simultaneously, and evaluate the using of fishing light intensity. |
