The whale shark (Rhincodon typus) inhabits Cenderawasih Bay at the Birdhead Seascape of Papua in high frequent sightings, but little is known about its genetic characteristics and connectivity. The study was conducted to characterize of the R. typus COI gene fragment from Cenderawasih Bay, in order to accurately compare with the 27 COI gene fragment sequences from the global whale shark deposited in the GenBank. A total of 28 meat samples of whale shark were collected by biopsy punch on a pole spear. The meat samples were extracted to obtain whole genome then amplified and sequenced to obtained COI nucleotides. The determined COI is a 669 bp, comprising of A = 26.5%, T/U = 30.5%, C = 28.3%, dan G = 14.7%. In total, 41 cutting sites of all the sequences ranged in size from 5-7 bp long. One COI single nucleotide polymorphisms and 2 haplotypes were identified. Single site substitution change from T to C for both haplotypes was observed. Overall, the haplotype diversity (Hd= 0.137) and nucleotide diversity (π=0.0002) were relatively low. A different nucleotide composition, number and arrangement of the sequences with the whale shark COI sequences from Cenderawasih Bay compared to COI gene fragment sequences from GenBank were observed. This study shows the availability of sequence of whale shark will contribute to aid further studies of molecular systematics, phylogeography, genetic differentiation, and conservation genetics.

The Sausapor Declaration has served as a stepping stone towards convening and balancing the dynamics of governmental politics, conservation efforts, the protection of customary communities’ rights, and the sustainable management of natural resources in Tambrauw District. The Declaration supported the establishment of Tambrauw as a Conservation District, while also acknowledging the rights of customary communities in shaping political priorities of the local government, which include: a) stewardship of extensive remaining tropical forests (91.9% forest cover); b) management of protected areas, which represent 77-80% of the total area of the District; c) acknowledging the cultural traditions of five major indigenous groups; and, d) securing the active support of formal institutions for these goals. Two stages have shaped the effort to establish the Conservation District.  The first stage involved the period prior to the formal declaration, while the second ecompasses development and implementation of related policies.  Establishing local regulations and protecting local communities required extensive lobbying with the provincial and national government, as well as advocacy in various seminars, including both national and international conferences that provided strategic opportunities for securing support for the Conservation District. These steps have been instrumental in gaining legitimacy and public support for relevant conservation policies and for protecting the rights of customary communities. As one example, the review of Tambrauw spatial planning documents  (RTRW) led to prioritizing eco-tourism as a leading sector for economic development, along with the creation of an overall agropolitan and renewable energy strategy.

Seagrass is a high level and a flowering plant that is fully adapted to life in the coastal and has ability to store carbon by 10% of the carbon content in the oceans. The research doing at Gunung Botak Bay Coastal South Manokwari Regency with objective of research to estimate seagrass density and to estimate rate accumulation of carbon from Enhalus acroides. Some the stages of the research done is density sample as long to period 2015 (April and Mei) into (September and Ocktober). Other sampling to collecting seagrass to estimate carbon storage in part like daun, rhizome root and substrat. Result to showing average carbon accumulation of seagrass in above below ground is rhizome part and higher in Statiun1 (13.16±3.8),stasiun 3 (5.4±2.9) dan stasiun 5 (6.2±1.1) or the generally accumulation carbon in the three is 8.24 kg from Enhalus acroides. Future more, accumulation carbon in sediment as a 1664,2 in dept 0-20 cm and 20-60 cm. Seagrass carbon storage capabilities will assist in mitigation efforts to reduce the impact of climate change in Indonesia, especially in West Papua.

The waters of South Sorong have potential shrimp resources, including abundant banana shrimp (Penaeus merguiensis de Man, 1888). This study aims to obtain information about the morphometric characteristics and growth of banana shrimp in the fishing area around the waters of Kampung Bakoi, South Sorong Regency, West Papua Province. Data collections were carried out in June and October 2019 using descriptive methods with direct observation techniques. Based on the results of data analysis, it was found that the total length of shrimp caught in Bakoi Village was in the range of 10 - 26.8 cm and the most were caught measuring 15.2 cm to 16.4 cm. The model of the relationship between length and weight of banana shrimp in Bakoi Village follows the equation Log W= 1,630+2,659 Log (L) or the form of negative allometric growth. Analysis of the relationship between total length (Y) and carapace length (X) (including rostrum) and the relationship between total length and carapace length (Z) (excluding rostrum) obtained the best estimator models, each following the logarithmic equations L = -2,188 + 10,226 Ln(PK) and L = 4,439 + 9,201 Ln(PKt) respectively.

Ikan karang merupakan salah satu bio indikator terhadap keberadaan terumbu karang. Penelitian ini bertujuan untuk mengetahui komposisi jenis ikan karang, sebaran dan hubungan panjang berat ikan konsumsi di perairan tersebut. Penelitian ini dilakukan pada tanggal 27 oktober – 1 november 2017 di perairan Numfor Timur dan Numfor Barat. Metode yang digunakan untuk pengambilan data adalah dengan pendekatan Line Transect (LIT) dengan kedalaman 3 dan 5 meter di ekosistem terumbu karang menggunakan alat bantu SCUBA dan pengunkuran hasil tangkapan beberapa nelayan. Dari hasil pengamatan LIT diperoleh 138 spesies dari 16 familly yang semuanya teridentifikasi sebagai spesies ikan karang. Selanjutnya dari pengukuran hasil tangkapan nelayan diperoleh dua jenis familly ikan yang dominan yaitu Pomacentridae, Labridae dan Caetodontidae. Selanjutnya untuk komposisi ikan yang terdata oleh nelayan adalah jenis Lutjanus lineatus, Chaerodon anchorago dan Chaerodon vunutus. Deskriptif dari tiap ikan ini untuk panjang adalah 17.60±2.72 dan berat 112.64±54.97, jenis ikan Chaerodon anchorago dengan panjang 19.86±1.68 dan berat 136±21.5,7, jenis Chaeredon dengan panjang 16.16±1.50 dan berat 97.85±24.69. Selanjutnya nilai hubungan panjang berat dari ketiga jenis ikan ini masing masing menunjukkan jenis Ikan Lutjanus lineatus (R. 0.857), Ikan Chaerodon anchorago (R. 0.99) dan jenis ikan Chaerodon vunutus (R. 0.61). Dengan keanekaragaman jenis ikan yang tinggi di pesisir Numfor Timur dan Numfor Barat, diharapkan dapat mendukung potensi Perikanan dari Numfor sebagai komoditi unggulan.

One of the mangrove forest area in Numfor Island is the Syoribo Coastal Coast currently the destruction of mangrove ecosystems is increasingly widespread due to the opening of land to be used as residential and development areas so that there is a reduction in the area of mangrove forests. The research was conducted in April 2018 at the Syoribo Village Coastal Coast of East Numfor District of Biak Numfor District of Papua Province. This study aims to analyze the types and distribution of mangroves, Analyze the composition of species and structure of mangrove vegetation (density, frequency, and dominance), Analyze the mangrove habitat is environmental condition affecting mangrove growth, Analyze texture of substrate which is overgrown by mangrove, Analyze the linkage between mangrove density and substrate texture found. The method used in this study is by combination between path method and line method then substrate analysis was conducted in laboratory. The results showed that in the four observation transects in 7 mangroves species were Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, Bruguiera cylindrica, Avicennia alba, and Xylocarpus granatum. The highest value index for tree, sapling and seedlings is the highest Bruguiera gymnorrhiza (197,82%), (160,71%), and (166,36%). Environmental conditions that affect mangrove growth are average temperature (27,6 0C – 29,4 0C), Salinity (6 ‰ – 24,3 ‰), Density (0,004 – 0,014), pH (7,12 – 7,57). The texture of the substrate overgrown by mangroves on the Syoribo, East Numfor have substrate criteria are dust silty clay loam, Silt Loam and sandy loam. Modeling the relationship between the density of tree level, spling, and seedling mangroves with substrate using multiple regression shows a close relationship between the two variables.
