Mangrove forests are ecosystems that make up coastal areas and river estuaries. The examples of mangrove ecosystems found in Indonesia are in Segara Anakan, Central Java. One of the aquatic biota with the economic value found in the mangrove forest ecosystem is the mud crab (Scylla spp.). The purpose of this study was to assess the distribution of mangrove crabs (Scylla spp.) to the presence of mangrove species in the mouth of the Donan River, Segara Anakan. A sampling of crabs and observations of mangrove vegetation were carried out at five stations spread from the river to the sea. The results showed that there were three types of mangrove crabs caught in the vicinity of the study, namely Scylla tranquebarica, S. olivacea, and S. serrata. The types of mangroves found include Rhizophora apiculata, R. mucronata, Avicennia rumphiana, A. alba, A. officinalis, and Nypa. Regression analysis showed that mangrove density correlated with the abundance of Scylla tranquebarica and Scylla olivacea, but contradicts the abundance of Scylla serrate. PCA analysis showed that the Crab species Scylla tranquebarica and Scylla olivacea were associated with mangroves of Avicennia alba, Avicennia rumphiana, and Rhizophora apiculata. Meanwhile, Scylla serrata crabs are associated with Avicennia officinalis.

Scylla serrata is one of the dominant muddy crabs caught in Mantehage Island coastal waters, North Sulawesi. The study was aim to determine the temporal distribution of S. serrata condition i based on carapace length - weight relationship and its condition factors. Data carapace width and weight of muddy crabs collected by enumerators from Oktober 2014 to April 2015. The results showed that b value of male (2.219 – 2.835) and female (1.264-2.352) were significantly different (P<0.05). Male and female crabs have a negative allometric growth pattern with b value of males tend to be larger than females. Range of values for K and Kn male crabs longer than females that male crabs tend to be fatter. Temporal distribution of this mangrove crab condition factors is assumed to be related with the reproductive cycle. The value is increasing since October to a peak season in January which estimated related to a peak of the muddy crabs spawning season in Mantehage Island coastal waters.   Key words: growth potential, Mantehage Island coastal waters, Scylla serrata _____________________________________________________________________ 1Staf Pengajar Fakultas Perikanan dan Ilmu Kelautan UNSRAT A b s t r a k   Scylla serrata merupakan salah satu jenis kepiting bakau yang dominan tertangkap di perairan Pulau Mantehage Sulawesi Utara. Penelitian ini bertujuan untuk mengetahui potensi pertumbuhan kepiting bakau ditinjau dari hubungan panjang karapas dengan berat.

  Banten Bay is located in the north of Java Island and influenced by anthropogenic activities around the bay. Increasing population growth and rapid development of industrial and urban activities around the waters of the Banten Bay can lead to an increased input of pollutants in the form of heavy metal in the water body. This study aims to analyze the Pb and Hg levels that accumulate in mud crab (Scylla serrata) in Cengkok coastal waters, Banten Province. Samples of the mud crabs were taken in the waters for six months, from March to August 2019. Analysis of heavy metal concentrations was carried out using the Atomic Absorption Spectrophotometric (AAS) AA 7000 series Shimadzu. Heavy metal (Pb and Hg) in the mud crab in Banten Bay were below the specified quality standard. The bio-concentration factor of the mud crab was low (<100). Results of the calculation of the maximum limit of consumption of the mud crab meat (that accumulates heavy metals in the human body) were 3.5 kg of meat/week for adults and 0.9 kg of meat/week for children.Keywords: Crustacean, pollution, limit of consumption.
