CATCH AND EFFORT INFORMATION FOR ALBACORE TUNA (THUNNUS ALALUNGA) BY INDONESIA’S LONGLINERS OPERATING FROM BENOA
Abstract: Albacore (Thunnus
alalunga - ALB) catch was the second highest tuna landed at Benoa Fishing Port
and they are mostly landed as frozen bycatch. This paper attempts to provide
information on ALB catch and effort trends by Benoa based longline vessels
collected by the Benoa Port-based Catch Monitoring and Scientific Observer
Programs. The ALB catch landed at the Benoa Fishing Port in 2010 was estimated
by the Research Institute for Tuna Fisheries (RITF) to be about 983.14 tons,
whereas based on the Indonesian Tuna Long Line Association (ATLI), ALB catch
landed at Benoa Fishing Port in 2010 amounted of 2,715.42 tons. This
discrepancy was due to sampling for frozen catch (including ALB) could not be
conducted in some companies and also there was one company that sell their
catch direct to the collector. The observed longline sets were concentrated
within the area between 10° - 20°S and 105° - 120°E. Since 2008, the observed
setting positions have never extended to south of 20°S. The higher catch rates
of ALB were in area south of 15°S.
