Fisheries Management of Blue Swimming Crab (Portunus pelagicus) based on Zoning Area in Pangkep Waters, South Sulawesi, Indonesia

Reproductive biology is one of the biological aspects that needed to formulate responsible management of blue swimming crab (BSC). The crab is one of the commercial fisheries commodities in South Sulawesi, Indonesia. Presently no information on the reproductive biology of this crab from Spermonde Archipelago, Sout Sulawesi. Therefore, the study aimed to analyze and compare gonad maturity stage(GMS)andgonadalsomaticindex(GSI)oftheBSCcaughtonthreeecosystemsnamelycoralreef,seagrass,andmangrovein Salemo Island, Spermonde Archipelago. GMS and GSI were analyzed descriptively for five months from March to July 2015. Results indicate there was a difference in GMS of the BSC caught in mangroves, seagrass, and coral reef. Generally, mangrove was dominated by immature BSC with GMS I and GMS II, while the BSC caught in the seagrass and coral reef BSC were dominantly mature and spawn GMS III, IV, and V. GSI BSC caught in mangrove ecosystem are smaller than GSI BSC caught in seagrass and coral reef ecosystems. Seagrass and coral reef ecosystems suitable for development no-take zone of the BSC.

Exploitation rate of the blue swimming crab (BSC) in Indonesian Fisheries Management Area (FMA) 712 is over-optimum level in 2016. Stocks concern in sustainable management is needed as an effort to maintain its availability. The objective of this study is to identify the stock unit of BSC based on Truss Network Analysis (TNA) of morphometric characters in FMA 712. The BSC was collect in five different locations, i.e. East Lampung, Lancang Island, Cirebon, Rembang, and Southern Madura. Measurements on TNA were carried out at 14 landmark points with 29 characters in carapace to analyze its morphometric characters. The cluster analysis showed that TNA method revealed two stocks units of BSC in FMA 712. The first stock was the BSC population of Southern Madura, and the other stock was the other four population. The longest Euclidean distance was found at Southern Madura indicating similarity level with other populations was low. The discriminant analysis demonstrated the different result. There were three group populations, which every population in one group were able to represent the other population, namely Lancang Island-Cirebon, East Lampung-Rembang, and Southern Madura. Regarding to this study, it is recommended to manage BSC in Southern Madura separately.

Maximum Economic Yield

Perikanan Rajungan (Portunus pelagicus) di Indonesia memberikan devisa sebesar US$ 246,14 juta dari ekspor pada tahun 2015 dan menghidupi 65.000 nelayan dan 130.000 pengupas rajungan di Indonesia. Berdasar nilai strategisnya ini, pemanfaatan perikanan rajungan perlu memperhatikan asas keberlanjutan sumber daya. Penelitian ini bertujuan menganalisa keberlanjutan pemanfaatan sumberdaya rajungan di Indonesia menggunakan model bioeokomi dari data hasil tangkapan rajungan di Wilayah Pengelolaan Perikanan (WPP) RI tahun 1977-2014. Hasil penelitian menunjukkan bahwa pemanfaatan sumberdaya rajungan di Indonesia memberikan rente ekonomi yang tinggi pada kondisi Maksimum Sustainale Yield (MSY) dan Maksimum Economic Yield (MEY) sedangkan pada rezim open access (OA) tidak memberikan rente ekonomi. Mengacu pada hasil penelitian maka pengaturan pemanfaatan sumberdaya rajungan dengan upaya dan produksi yang mendekati batas MEY diharapkan dapat menjamin keberlanjutan usaha rajungan baik secara biologi maupun ekonomi. Adapun pemanfaatan secara open access (OA) hendaknya dibatasi atau dihindari karena kondisi ini tidak dapat menjamin berkelanjutan perikanan rajungan baik secara biologi maupun ekonomi.The Blue Swimming Crab (BSC, Portunus pelagicus) fishery in Indonesia provides revenue of US$ 246.14 million rom exports in 2015 and supports 65,000 fishermen and 130,000 pickers in Indonesia. Based on this value, the harvest of BSC fishery should consider the principle of resource sustainability. This study aims to analyze the sustainability of utilization of crab resources in Indonesia using bioeocomic model applied to the BSC catch data from all Fisheries Management Areas (FMA) in Indonesia from year 1977 until 2014. The results show that BSC harvest in Indonesia gives high economic rents under the conditions of Maximum Sustainale Yield (MSY) and Maximum Economic Yield (MEY) while the open access regime does not provide any economic rents. Referring to the results of the study, the arrangement of utilization of crab resources with efforts and production close to the limit of MEY is to be expected to ensure the continuity of the crab business both biologically and economically. The direction toward open access should be limited or avoided because this condition will lead to the unsustainable practices of the BSC fishery both biologically or economically.

Abstract. Hidayani AA, Fujaya Y, Trijuno DD, Rukminasari N, Alimuddin A. 2020. Genetic diversity of blue swimming crab (Portunus pelagicus Linnaeus 1758) from Indonesian waters (Sunda and Sahul Shelf, Wallacea region): Phylogenetic approach. Biodiversitas 21: 2097-2102. Blue swimming crab is one of the exploited fisheries commodities in Indonesia. This condition has contributed to the decline of their genetic diversity. The information on genetic diversity assumes importance for the conservation and the cultural purposes of species. The study aimed to determine the genetic diversity of blue swimming crabs from Indonesian waters using phylogenetic analysis. We conducted sampling of crab from several Indonesian waters, such the Aceh and Semarang (representing Sunda Shelf), Barru, South Sulawesi, and Maumere, Flores (representing Wallacea region) and Sorong, Raja Ampat and Kaimana (representing Sahul Shelf). Genetic diversity in this study using mitochondrial DNA (mtDNA) by implementing the method of Cytochrome c Oxidase Subunit I (COI). According to the findings, the blue swimming crabs from our study sites had a high genetic diversity variation. Three groups of crabs were determined using phylogenetic tree which formed three different unique clades. There was the same haplotype of crab observed from different locations, barring a sample from the Sahul Shelf which has a unique haplotype. There was no genetic speciation of crab samples from the Sunda Shelf and the Wallacea region were observed, except samples from the Sahul Shelf. Hybridization might occur between species of the crabs due to the finding of a cryptic species.

Sustainable Fishery

The blue swimming crab (BSC), Portunus pelagicus (Linnaeus 1758), inhabits coastal areas of Southeast and East Asia, and is one of high fisheries commodities with an export value for Indonesia and an increasing global market demand, annually. However, the data of genetic diversity and their spatial connectivity of populations in Indonesia are not yet known, even when it is important to inform stock unit management and sustainable use. This study aimed to determine the genetic diversity and differentiation of blue swimming crabs across Indonesian populations in different Fishery Management Area (FMA), and their spatial genetic connectivity, as well as to deliver implications for sustainable fishery. A total of 297 individuals were collected and amplified using cytochrome oxidase I mitochondrial DNA. This study has showed the highest values for haplotype and nucleotide diversity in the eastern part of Indonesia, where exploitation is relatively low. Significant genetic differentiation between populations (FST = 0.954; p < 0.001) and the fisheries management areas (FST = 0.964; p < 0.001) were revealed. Low spatial connectivity was observed between populations in a distance of at least more than 60 kilometers. This study suggests that BSC populations in Indonesia, likely have several stock units, and preferably different fisheries management plans and actions across the region thoroughly and simultaneously. This would be effective for management and their sustainable conservation.
