Prey safe code es xe11/21/2023 This trend also occurred in regions where the blue swimming crab fisheries developed earlier, and most of blue swimming crab fisheries tend to be overfishing. The catch per trip is also fluctuated even though the unit and dimension of fishing gears have increased. However, according to the government and industrial meat production, the average size of blue swimming crabs landed has been declining since 2008. This product demands to be ecolabel certified and traceability systems now. The crab meat has been exported approximately 20,000mt per annum over the last decade, primarily to USA markets. The Indonesian blue swimming crab fishery has developed rapidly since the 1990s and became an important source of coastal communities’ income. Since this species has moderately long planktonic larval stages and might have high mobility during the crab phase, it is occurs a high gene flow level within and between populations The blue swimming crab has a life cycle with five larval stages, while larval duration might be for 26–45 days, afterwards follows the crab phase. pelagicus couldn’t be found at nearshore waters where water salinity is less than 10 PSU, and this species would migrate from estuaries to marine waters as a reaction to lowered salinities. pelagicus inhabits benthic coastal environments for both estuaries and nearshore and females migrates into high salinity waters for spawning, but they seem not to return into the estuaries or nearshore waters after spawning, except the larval stage. The spatial connectivity of blue swimming crabs is influenced by their life cycle and other environmental parameters. The blue swimming crab ( Portunus pelagicus Linnaeus, 1758) inhabits coastal waters of Southeast and East Asia.

This would be effective for management and their sustainable conservation.Ĭitation: Madduppa H, Martaulina R, Zairion Z, Renjani RM, Kawaroe M, Anggraini NP, et al. 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. Low spatial connectivity was observed between populations in a distance of at least more than 60 kilometers. Significant genetic differentiation between populations ( F ST = 0.954 p < 0.001) and the fisheries management areas ( F ST = 0.964 p < 0.001) were revealed. This study has showed the highest values for haplotype and nucleotide diversity in the eastern part of Indonesia, where exploitation is relatively low. A total of 297 individuals were collected and amplified using cytochrome oxidase I mitochondrial DNA. 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. 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. 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.
