This annual report for the period 1 January - 31 December, 2018, contains summary data of fishing 

effort and catch statistics as reported on longline log sheets for the American Samoa permitted 

longline fishery. Data in this report originate from the PIFSC Information Management System 

(Oracle) table LLDS_RPT_STATS_AS20190211_RFMO, representing preliminary data received as 

of 11 February 2019. Catch and effort statistics are based on date of longline haul. When a statistic 

(number of vessels, trips) involves dates of haul in two summary periods (i.e., years, semi-annual, 

quarters), the item is counted in both summary periods. Thus, a trip total is for “partial and

completed” trips. As such, these statistics are not additive (i.e., sum of four quarters is not the total 

for the year, etc.).

The following table shows fishery statistics for the stated time period, area, and set type, and 

includes effort (number of vessels, trips, sets, and hooks set), and for each listed species, organized

by pelagic management unit species (PMUS) groups of billfish, shark, tuna, and other, the table 

includes the number of fish caught, kept, and released, and the catch per unit effort (CPUE), 

measured as the number of fish caught per 1,000 hooks.

Additional figures graph catch numbers and effort for important species for the stated time period, 

area, and set type, for years 2000-2018.
