Abstract

Mangrove forests on the coast of West Papua hold high ecological and economic values, yet utilization pressure continues to increase. This study aimed to analyze the impacts of mangrove utilization activities on ecosystem conditions and on the socio-economy of the community in Kladufu Village Km 10, East Sorong District, Sorong City. The research was conducted with using a descriptive survey method with semi-structured interviews of 31 purposively selected respondents. Data were analyzed descriptively (quantitative and qualitative). Results showed that most respondents were male (58.1%); of productive age, with low education levels (elementary school 38.7%, junior high school 35.5%); and worked as housewives, stone collectors, mangrove loggers, or fishermen. As many as 67.7% of respondents very frequently utilized mangroves, mainly for firewood and construction materials. Logging frequency was very high (61.3%). Nevertheless, 41.9% of respondents perceived mangrove conditions as better than three years earlier due to replanting activities. Community participation in management was mostly voluntary (71.0%) and motivated by confidence in local knowledge (80.6%). A total of 83.9% desired involvement from the planning stage through to benefit sharing. The utilization impacts on the ecosystem were twofold: improvement in rehabilitated areas versus degradation elsewhere. Impacts on the community were reflected in high economic dependence, alongside strong ecological awareness and social capital. Capacity building and livelihood diversification are needed to achieve mangrove sustainability.

Abstract

Large pelagic tuna (Thunnus sp.) is a high-value fishery resource that significantly contributes to Indonesia’s fishing industry. This study evaluates the effectiveness of two primary fishing gear types—hand line and kite line—in tuna fisheries in Makbon waters, Sorong Regency, West Papua. Field research was conducted using a survey approach with direct observations on 14 fishing trips. Results demonstrated that hand line yielded 52 tuna individuals (65.8% effectiveness), while kite line yielded 27 individuals (34.2% effectiveness). This difference is significant and influenced by technical factors including operational depth, gear selectivity, and target fish behavior. Hand line effectively reaches optimal tuna depths and exhibits higher selectivity for catching marketable-sized individuals. This research emphasizes the importance of appropriate gear selection in enhancing catch productivity while maintaining tuna resource sustainability. Policy recommendations include regulating hand line use as the primary fishing gear and implementing monitoring systems to ensure the capture of adult fish

Abstract

Rastrelliger kanagurta is a small pelagic fish commodity with high economic value and is vulnerable to overfishing. This study aimed to analyze the length-weight relationship as an indicator of growth pattern of Indian mackerel landed at the Fish Landing Site (TPI) of Sorong City, West Papua. Sampling was conducted purposively from April to June. A total of 191 fish were measured for total length (mm) and body weight (g). The length-weight relationship was analyzed using logarithmic linear regression, followed by a t-test to determine the growth pattern (isometric or allometric). The results showed that the caught fish were dominated by the length class of 185.5–200.5 mm (31.9%) and weight class of 71.5–86.5 g (28.3%). The combined regression coefficient b (April–June) was 2.2498, with a calculated t-value (1.6125) < t-table (1.9725) at 95% confidence level, indicating a negative allometric growth pattern. This means that length gain is faster than weight gain, suggesting relatively slender body condition, presumably due to fishing pressure or food limitation. These findings confirm that the population of Indian mackerel in Sorong waters has experienced a shift in growth pattern, necessitating adaptive management measures such as mesh size regulation and enhanced monitoring of fishing grounds

Abstract

Seagrasses are flowering plants (Angiospermae) that grow in shallow marine environments and possess rhizomes, leaves, flowers, and fruits similar to vascular plants on land. This study aimed to identify seagrass species, analyze vegetation conditions including frequency, density, and cover of each species, and examine factors affecting seagrass growth in the coastal area of Soop Village, Sorong Islands District, Sorong City, West Papua. The research was conducted from August to October 2014 using the line transect method with 50 cm x 50 cm quadrats placed systematically along two transects (each 250 m long). Data were analyzed using calculations of frequency, density, cover, and the Important Value Index (IVI). The results revealed three seagrass species: Enhalus acoroides, Cymodocea rotundata, and Syringodium isoetifolium. The relative frequency values were 54%, 26%, and 20% respectively; relative density values were 68%, 16%, and 16%; and relative cover values were 54%, 26%, and 20%. Enhalus acoroides dominated the community with an IVI of 176%. Based on the Decree of the Minister of Environment Number 200 of 2004, the seagrass meadow condition was classified as unhealthy to poor due to anthropogenic pressures such as tourism activities, boat mooring areas, indiscriminate anchoring, and domestic waste disposal. Management efforts including waste bin provision, boat mooring area regulation, and banning of environmentally damaging fishing gear are necessary to restore the seagrass ecosystem
