Abstract

This study aims to determine the distribution of length to weight, sex ratio, gonad maturity level of julung fish (Hemiramphus lutkei) traded in Sanggeng and Borobudur Manokwari fish markets, West Papua. Research data collection was carried out for ± 1 month, namely February - March 2021, using a descriptive method. The number of fish samples collected was 542 fish. The results of the analysis of the size distribution of julung-julung fish during sampling for body length ranged from 219 – 355 mm for males and 215 -380 mm for females, with a body weight range of 27-53 grams for males and 30-65 grams. The sex ratio analysis of julung julung fish was obtained for males (321 fish) and females (221 fish) significantly different, which means this ratio deviated from the ideal value of 1:1. Based on the results of the analysis show that the value of X2 -count > X2 -table, then H0 is rejected, which means the sex ratio of male and female fish is not balanced from TKG I-VII for males and TKG II-VII for females and mostly found in TKG III conditions. The size of the male julung fish when the gonads first mature was estimated at a length of about 230-260 mm and the female at a size of 250-280 mm. The average Gonad Somatic Index (GSI) of female julung fish was 0.0876 and the standard error was 0.0061 with a GSI range of 0.0092 – 0.7574. The relation- ship between TKG and GSI shows that the increasing stage of fish gonad maturity will be followed by an increase in the value of the fish gonadal index.

Abstract

Seagrasses and sea cucumbers have a close relationship in determining ecological functions. The purpose of this study was to investigate the relationship between seagrass density and sea cucumber abundance on Meosmangguandi Island, Biak. The research was conducted in August-September 2021 at two stations. The location was chosen purposively on the East side (Station I, conservation location) and the West side (Station II, around residential areas and fishing activities). The 5m line transect method (2.5m to the right and 2.5m to the left) is used to reach the destination. The study found 6 species of seagrass namely C. rotundata, T. hemprichii, E. acoroides, H. pinifolia, H. ovalis and Syringodium isoetifolium, and 9 species of sea cucumbers namely Actinopyga lecanora, A. miliaris, A. mauritiana, Bohadschia similis, Holothuria atra, H. coluber, H. scabra, H. albiventer, and teripang malam. Percentage of seagrass cover at Station I was 85.51% and Station II was 57.71%, with a relative density of seagrass C. rotundata 39.10% and T. hemprichii 27.09%. The relationship between the density of seagrass C. rotundata and the abundance of sea cucumbers A. lecanora 4.285 > X2 (1:0.05); T. hemprichii with A. mauritiana 6.887> X2 (1;0.05); seagrass C. rotundata with A. miliaris 4.285 > X2 (1:0.05); A. miliaris with seagrass H. pinifolia 7.048 > X2 (1:0.05); density of seagrass T. hemprichii with abundance of sea cucumber B. similis: 5.274 > X2 (1:0.05); H. atra 5 > X2 (1:0.05); and H. coluber 5.172 > X2 (1:0.05), indicating an association between seagrass density and sea cucumber abundance.

Abstract

Mantis shrimp is one of the marine organisms that has a very abundant diversity of species. The similarity of morphology of this group make it difficult to identify morphologically. Therefore, identification was carried out using a DNA barcoding approach. The purpose of this study was to identify the mantis shrimp species from Manokwari waters using molecular techniques. The CO1 gene fragments were amplified by using LCO and HCO primers. The DNA sequences obtained were analyzed for homology, phylogeny, and genetic distance using MEGA X software. A total of 537 base pairs of CO1 gene fragments of mantis shrimp from Manokwari were obtained. The results of the homology analysis on GenBank, show the highest similarity of 91.18% with sequences from the genus Gonodactylus. Analysis of phylogenetic tree and genetic distance showed the same results and supported each other with homology analysis on GenBank data.

Abstract

The Lutjanidae family has a wide range of varieties, posing challenges in their morphological identification. Molecular identification is crucial for augmenting the current morphological data as a comprehensive database for documenting the presence of economically significant fish species in Nabire water. This article provides a comprehensive analysis of the morphological and genetic characteristics of red snapper species, as well as assessment of the evolutionary connections among snapper fish found in the water. This study aims to analyze the morphological and genetic characteristics of red snapper species and assess the evolutionary relationships among red snapper found in the sea waters. The DNA extraction procedure was conducted according to the instructions provided by the Geneaid gSYNC DNA extraction kit. The molecular marker used is the DNA barcode of the cytochrome oxidase subunit I (CO1) gene. A total of 29 individuals were identified, representing 8 species, namely Lutjanus timoriensis, Lutjanus gibbus, Lutjanus bohar, Lutjanus papuensis, Pinjalo lewisi, Etelis coruscans, Pristipomoides multidens, and Aphareus rutilans. The molecular analysis indicated that there was a fragment length of 620 base pairs (bp). P. multidens and L.  gibbus had the greatest genetic distance (0.22), whilst the species L. bohar and L. gibbus had the smallest genetic distance (0.11). The phylogenetic tree reconstruction yielded 8 monophyletic clades. Based on morphological and genetic analysis, eight species of the Lutjanidae family were identified in Nabire waters. Research is needed on biological parameters such as size when first caught, optimum length of capture and size when first gonad mature.

Abstract

Sistem sasi sebagai kearifan lokal telah diterapkan di Nabire, Papua Tengah, untuk mengelola sumber daya laut secara berkelanjutan, termasuk teripang yang memiliki nilai ekologis dan ekonomis tinggi. Namun, keberhasilannya bergantung pada efektivitas konservasi, yang mencakup penegakan aturan lokal, monitoring dan evaluasi, serta dukungan pemerintah dan maupun nonpemerintah. Penelitian ini bertujuan untuk mengukur efektivitas konservasi pada ekosistem laut serta peningkatan kesejahteraan masyarakat lokal, dengan menggunakan data kuantitatif dan kualitatif yang dikumpulkan melalui observasi, wawancara, dan analisis dokumen. Hasil penelitian menunjukkan bahwa efektivitas pengelolaan berbasis sasi berada pada kategori sangat baik, dengan kontribusi signifikan terhadap perlindungan habitat laut (67,74%) dan diversifikasi sumber daya (67,74%). Penegakan aturan lokal (67,74%) dan dukungan pemerintah serta non pemerintah (70,97%) menjadi faktor kunci dalam keberhasilan ini. Outcome utama dari implementasi sasi adalah peningkatan kesejahteraan masyarakat (70,97%) melalui peningkatan pendapatan dan pemberdayaan sosial ekonomi, serta perlindungan habitat yang mendukung keberlanjutan ekosistem laut. Efektivitas konservasi memainkan peran penting dalam menghubungkan berbagai faktor konservasi teripang dengan outcome yang dihasilkan. Untuk meningkatkan keberhasilan implementasi sasi, direkomendasikan penguatan Monev, harmonisasi aturan adat dan formal, serta peningkatan kolaborasi antara masyarakat adat, pemerintah, dan lembaga terkait. Sistem sasi dapat menjadi model konservasi berkelanjutan yang relevan untuk diterapkan di wilayah lain dengan kondisi ekosistem serupa.

Abstract

Genetic diversity is one level of biodiversity that is very importan for the resilience of biota in the face of environmental pressures such as cilmater change. However, information on the genetic diversity of red snapper in Kaimana water is still very limited. This study determines the genetic diversity of red snapper (Lutjanus erythropterus) in Kaimana waters, West Papua, to support conservation and sustainable management. The methods used include PCR, DNA sequencing, and phylogenetic analysis using MEGA11, with samples taken from the Kaimana fish market. The results of this study show differences in the percentage of adenine and guanine in sample B81.01, with an average codon composition of 218 codons, where UCU(G) Serine has the highest percentage of 13.8% and RSCU 2.38%, and 20 types of amino acids were detected. Lutjanus erythropterus has 3 haplotypes, with 2 universal haplotypes and 1 specific. In Kaimana waters, the haplotype diversity (hd) value is 0.50000 and the nucleotide diversity (π) is 0.00091, which is influenced by the large population size and high migration ability.

Abstract

ABSTRACT: The rabbitfish, Siganus canaliculatus is one of the components in the coastal waters ecosystem (mangrove, seagrass, and coral reef) and also has important economic value for coastal communities, but information is still limited, especially in Papuan waters. This study aims to analyze the size composition and growth patterns of rabbitfish (Siganus canaliculatus) based on habitat differences in the waters of Kwatisore, Yaur District, Nabire Regency. Sampling was carried out at three locations representing various habitat types, such as mangrove, seagrass, and coral reef. The data collected included the total length (mm) and body weight (g) of the fish, which were then analyzed using the length-weight relationship model W = aLb. The results showed that the average body length and average body weight were greater in the coral reef habitat type, but relatively the same among the three research locations. The overall growth pattern (habitat type and location) with a tendency for body length to increase faster than body weight (negative allometric pattern) with a b value ranging from 2.771 to 2.888. The size and growth patterns obtained in this study indicate connectivity between locations and habitats, although both habitat types show different roles in the life cycle of this fish. This study provides important information for ecosystem-based management of the rabbitfish resource in the coastal area of Nabire.

Abstract

ABSTRACT: This study examines the microhabitat characteristics of the endemic rainbowfish Melanotaenia arfakensis in two major rivers of Tambrauw, Southwest Papua—Api River and Asiti River—focusing on the spatial dynamics of environmental parameters from upstream to downstream. Results indicate that water temperature, dissolved oxygen (DO), depth, current velocity, and river width show significant spatial trends and directly influence the survival of M. arfakensis. The upstream zones, characterized by lower temperatures (23–26°C), high DO levels (>7 mg/L), moderate current, and stable depth, are identified as optimal habitats and conservation priorities. In contrast, the midstream and downstream zones exhibit gradual habitat degradation, including temperature increases up to 29.1°C and decreased DO levels, approaching the physiological tolerance limits of the species. This decline in microhabitat quality correlates with riparian vegetation loss and anthropogenic pressures. Therefore, an effective in situ conservation strategy must be spatially explicit, adaptive, and participatory—emphasizing thermal refugia protection in the upstream zones, ecological restoration in the midstream, and integrated watershed management with community involvement in the downstream areas. Longitudinal connectivity and the integrity of the entire riverine ecosystem are essential for ensuring the long-term viability of this endemic species.

Abstract

The vulnerability of mangrove habitats to environmental changes driven by anthropogenic activities and climate change is a critical concern for sustainable ecosystem management. This study assesses the vulnerability of mangrove habitats along the coastal area of Biak Timur District, Papua, using the Coastal Vulnerability Index (CVI) method. The CVI integrates five key variables: coastline profile, duration of tidal inundation, maximum tidal inundation height, salinity, and substrate type. Coastline profile data were derived from a decadal analysis (2013–2023) of shoreline changes. Tidal inundation duration and height were obtained through tidal data analysis, while salinity and substrate data were collected through field surveys and laboratory analyses. Each variable was scored and weighted within the CVI framework. The results indicate that the mangrove habitat in Biak Timur is in the "high vulnerability" category, with a CVI score of 5.69. This suggests a significant susceptibility to degradation from environmental changes, particularly those caused by human activities and climate change. Effective management should focus on minimising anthropogenic impacts and promoting sustainable use of mangrove resources.
