The Using of Harvest Control Rule, ABC Calculation Rule 2, the Case Study of Swordfish (Xiphias gladius Linnaeus, 1758) Catch Data
抄録
The Catch data of swordfish from Indian Ocean was provided during the scientific working group on neritic tuna stock assessment in Southeast Asian, SEAFDEC/MFRDMD, Malaysia in 2016, in order to be used as the practice for participants. The result was first analyzed by ASPIC program to calculate the MSY level of swordfish, which given the MSY level was 32,100 MT. The using of Allowable Biological Catch (ABC) Rule 2 concept was given the range of catch quota based on the recently data (3 years data). The result from rule 2 – 1 (the CPUE based analysis) was giving the catch quota range as 23,126.7 MT and 18,501.4 MT as the higher and lower range respectively and current CPUE was about 0.4773 kg/1000 hooks which ABC range of CPUE was between 0.4942 and 0.3952 MT, respectively while the result from rule 2 – 2 (the catch based analysis) was giving the catch quota range as 31,132.3 MT and 24,905.9 MT as the higher and lower range respectively.
