Sustainability of blue swimming crab Portunus pelagicus commodity in Banten Bay, Indonesia

Blue swimming crab (Portunus pelagicus) is the third highest commodity fisheries in Indonesia after shrimp and tuna. One of the blue swimming crab (Portunus pelagicus) deployments in Indonesia is in the area of Banten Gulf waters. Fishery statistical production data from years 2007-2017 from Archipelago Fishing Port (AFP) Karangantu experienced a peak in 2004 with 326,730 kg with fishing effort for 5.644 trip. While the amount of the lowest production occurred in 2007 with a total production of 19,225 kg and the efforts of 1.998 catching trip. For the calculation of CPUE that has been done can be seen that the highest CPUE values occurred in 2002 which reached 26,929.667 kg/boat, while the lowest CPUE values occurred in 2010 which only reached 288 kg/boat. Sex ratio was dominated by male P. pelagicus with a ratio of 2:1 (male:female), carapace width (CW) ranged from 6.2 to 18.4 cm with CW dominance from 11.2 to 12.5 cm. P. pelagicus CW-sized under 9 cm was represented by 1.39%, between 9-11 cm CW by 30.65% and with CW size above 11 cm by 67.96%. Pairwise comparison analysis with an index value of 46.19% indicated a less sustainable status. After the efforts made through improvements to the attributes that have a value of high sensitivity and negative effect on leverage analysis, the obtained value into a sustainability index is 59.97% with fairly sustainable categories in which an increase in the index leads to a very sustainable status.
