  • Description:
    The tables in this report include information requested by the NOAA Fisheries Pacific Islands Regional Office for their annual review of seabird interactions and Southwest Regional Office for their submission to the IATTC for use in preparing reports concerning seabird and sea turtle bycatch within the IATTC Convention Area. Tables 1 through 4 provide the requested bycatch estimates for seabirds and sea turtles. Tables 5 and 6 provide the requested information about fishing effort. The estimates and measures of effort are for all longline trips landing in the specified years, 2017 or 2018. When computing effort within the IATTC Convention Area for Tables 5 and 6, a fishing operation (set) was considered within the region if at least one of the recorded locations (begin set, end set, begin haul, or end haul) was within the region. The total number of trips within the IATTC Convention Area is the number of trips that had at least one fishing operation (set) in the region. The number of hooks hauled on a fishing operation assigned to the IATTC Convention Area was the number of hooks divided by the number of recorded locations within the area. For example, if the end set and begin haul were located within the area and the begin set and end haul were located outside the area, the number of hooks hauled was divided by 2 to derive the number of hooks assigned to the area. The total number of hooks within the IATTC Convention Area is the sum of hooks assigned to the area. The methods used to sample the deep-set fishery and compute the point estimate for the fishery are described in McCracken (in prep.b), and methods used to estimate the standard errors are described in McCracken(in prep.a).
