Abstract

Fisheries management ideally could prevent the occurrence of overfishing which nowadays has occurred globally, including in Indonesia.  On the basis of fishing status and biology of skipjack tuna, as well as analysis of relationship between sea surface temperature and chlorophyll-a with skipjack tuna catches,  the fisheries management should implement zoning regulation. The north zone was suggested to be prioritized as a conservation area for protecting skipjack juvenile (< 46,5 cm FL) from fishing activity.  The middle and south zones were suggested to be fishing area where sustainable fishing is applied.  The Application of these regulations has an implication on total allowable catches from Bone Bay.  The number has lower value than the previous MSY and F-opt values.  Number of skipjack tuna which was allowed to be caught in the north zone is 573 ton yr -1 , in the middle zone was 5,820 ton yr and in the south zone was 2,210 ton yr -1 .   Overall, the value of allowed number of skipjack tuna catches in Bone Bay was estimated to be 8,600 ton yr effort per year is equivalent with 5,376 operational trips from pole and line boats.   -1 with fishing-1

Abstract

The Bone Bay is part of Fisheries Management Zone WPPI 713 that covers Makassar strait, Flores sea and Bali sea. To such vast marinearea, fisheries management can be started from smaller region, e.g. embayment waters. Biological characteristics of skipjack tuna (Katsuwonuspelamis) are some of important information for developing fisheries management in the area. This research was aimed to determine length-weight relationship, size composititon, growth pattern and biologically feasible size of the fish. Data were obtained from fish caught byfisherman from Januari to December 2007. The bay was divided into three study areas, i.e. Northern, Centre and Southern Zones. The bcoefficients for length-weight relationship in the three zones were equal 3 [not significant]. The average fork-length (FL) in each zoneshowed similar trends: increased from January to June, then stabilized until December. Using von Bertalanffy’s growth model, the maximumFL (L ∞ of 759.75 mm is estimated for fish at age of 84 months. The length at first maturity of the fish is 465 mm (FL).
