Description: This layer depicts the north pacific albacore tuna charter boat fishing effort expressed as average number of vessel fishing days per 20km block from 2002 to 2020. Data includes logbook data for all vessels that fished off the coast of Oregon.The Oregon charter albacore tuna fishery targets albacore using hook-and line gear. The fish start migrating into the waters off Oregon around the end of June, and are most commonly found in clear blue water (where the surface temp is 62 degrees or more). The best fishing is typically in July and August, but fish are still available through early October. Most years, tuna fishers must travel 30 miles or more offshore to find albacore. The layer was developed using the kernel density function in ArcPro. Kernel density estimates were created using the pointdensity spatial analyst tool. Charter albacore logbook data were used to create points that met the following criteria:Points that intersected land were removedPoints that did not meet the rule of three unique vessels per 20km grid cell were removedThese filters removed 5% of the points for all yearscombined.These point locations were used as the population field with an output cell size of 20km and a search radius of 0.5 cells. Fishery logbook data are recorded on standardized data sheets by fishermen during their fishing operations. The logbooks are later turned over to SWFSC for data entry and processing. Because the data are recorded by many independent sources, ODFW cannot guarantee the accuracy of all logbook data.
