Analysis of the Average Catch per Fishing Trip of Skipjack Tuna (Katsuwonus pelamis) on Pole-and-Line Vessels Operated by PT Radios Apirja Sorong
type: item
description: This study aimed to examine the implementation of skipjack tuna (Katsuwonus pelamis) and tuna fishing operations using the pole-and-line fishing method at PT. Radios Apirja, Sorong Regency, West Papua. The research employed a descriptive method, with data collected through field observations, interviews, and documentation during fishing activities. The observed variables included the stages of fishing operations, the use of live bait, fishing grounds, and the catch obtained. The results showed that the pole-and-line method is an effective and selective fishing gear for catching skipjack tuna and tuna. The success of fishing operations is strongly influenced by the availability of live bait, oceanographic conditions, and the skills of the crew in operating the fishing gear. The fishing grounds located around the waters of Misool and Waigeo possess high potential for pelagic fish resources, thereby supporting the productivity of fishing activities. In addition, the fishing operations conducted by PT. Radios Apirja contribute to the local economy through partnership programs established with fishing communities. Therefore, the use of pole-and-line fishing gear can serve as an alternative approach for sustainable fisheries management in the West Papua region

Effects of Dietary Vitamin C Supplementation on Feed Intake and Growth Performance of Nile Tilapia (Oreochromis niloticus)
type: item
description: Vitamin C plays an essential role in maintaining immune function, reducing stress, accelerating wound healing, and supporting collagen synthesis in fish. Adequate dietary vitamin C supplementation can enhance nutrient utilization and promote fish growth and survival. This study aimed to evaluate the effect of dietary vitamin C supplementation on the growth performance and feed utilization of Nile tilapia (Oreochromis niloticus) and to determine the optimal dosage for growth enhancement. The study employed an experimental method using a Completely Randomized Design (CRD) consisting of four treatments and three replications. The treatments consisted of a control diet (without vitamin C supplementation) and diets supplemented with vitamin C at levels of 0.5%, 1.0%, and 1.5%. The observed parameters included absolute weight gain, specific growth rate (SGR), daily growth rate, absolute length gain, feed conversion ratio (FCR), feed efficiency (FE), and survival rate (SR). The results showed that dietary vitamin C supplementation significantly improved growth performance, feed efficiency, and survival of Nile tilapia (p<0.05). The best performance was obtained in the treatment containing 1.5% vitamin C, resulting in an absolute weight gain of 2.16 g, specific growth rate of 1.6% day⁻¹, daily growth rate of 0.05 g day⁻¹, absolute length gain of 4.97 cm, feed conversion ratio of 0.94, feed efficiency of 91.80%, and survival rate of 100%. However, the differences in feed conversion ratio were not statistically significant (p>0.05). In conclusion, dietary vitamin C supplementation enhanced growth performance, feed utilization efficiency, and survival of Nile tilapia. The optimal dosage observed in this study was 1.5% vitamin C supplementation in the diet

Analysis of Seagress Vegetation in Soop Village, Sorong Islands District, Sorong City
type: item
description: 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

Fish Community Structure and Response to Anthropogenic Pressure in the Mangrove Ecosystem of Kladufu Village, East Sorong District
type: item
description: The mangrove ecosystem in Kladufu Village, East Sorong District, faces escalating pressure from land conversion and settlement expansion, which threatens to alter estuarine fish community structures. This study evaluated species composition, abundance, and community responses to environmental gradients and anthropogenic stressors in the area. Field sampling was conducted over four weeks using gill nets (1-, 2-, and 3-inch mesh sizes) across two stations representing relatively intact and fragmented mangrove habitats. Concurrent physicochemical measurements were recorded. Ten fish species were documented, primarily belonging to Leiognathidae and Mugilidae. Abundance patterns exhibited a pronounced spatial shift: Station I (salinity 30‰) was dominated by Mugil cephalus (35.9%), while Station II (salinity 20‰, adjacent to residential areas) showed absolute dominance by Aurigequala fasciata (51.5%). Diversity and evenness indices ranged from moderate to low, accompanied by elevated dominance values at the impacted site, indicating community simplification driven by habitat degradation and domestic effluent inputs. Salinity gradients and mangrove conversion emerged as the principal drivers of species distribution. These findings highlight the urgent need for targeted mangrove rehabilitation and ecosystem-based fisheries management to maintain the area’s ecological function as a nursery ground and sustain local coastal fisheries.

Length-Weight Relationship and Negative Allometric Pattern of Male Mackerel (Rastrelliger kanagurta) at Sorong Fish Landing Site, Southwest Papua
type: item
description: 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

Effectiveness of Hand Line and Kite Line Fishing Gear in Tuna (Thunnus sp.) Fisheries in Makbon Waters, Sorong Regency
type: item
description: 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

Community Dependence and Participation in Mangrove Management: A Case Study in Kladufu Village, Km 10, East Sorong
type: item
description: 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.

Diversity of Seagrass Types and Conditions in the Waters of Suprau, Maladum Mes District
type: item
description: Seagrass beds are one of the ecosystems located in coastal areas or shallow marine waters. The uniqueness of seagrasses compared to other marine plants lies in their extensive root system and rhizome network. This type of rooting system causes seagrass leaves to become dense, which greatly benefits the productivity of the seagrass bed ecosystem. This study aimed to determine the species diversity and condition of seagrass beds on Suprau Beach, Maladum Mes District. Three seagrass species were found on Suprau Beach: Halodule pinifolia, Halodule uninervis, and Cymodocea serrulata, with relative cover percentages of 50%, 33.3%, and 16.7%, respectively. Based on the analysis of seagrass bed conditions in Suprau Waters, the ecosystem was classified as damaged or poor/unhealthy and impoverished according to the Indonesian Minister of Environment Decree No. 51 of 2004.

Condition of Live Stone Coral Cover on Suprau Beach, Maladoom Mes District, Sorong City
type: item
description: Coral reefs are tropical marine ecosystems that are very important for the sustainability of fishery resources and coastal protection. This study aims to evaluate the condition of live stony coral cover at Suprau Beach, Maladoom Mes District, Sorong City using the Point Intercept Transect (PIT) method. Observations were conducted at three stations at a depth of 3-5 meters. The results showed that the average live coral cover was 45.33%, which is classified as moderate. Specifically, Station I had excellent coral cover (80%) dominated by Non-Acropora corals of the Coral Branching type from the Porites family; Station II showed moderate conditions (34%) with a dominance of Non-Acropora corals of various life forms; and Station III was in a damaged condition (20%) with high coverage of dead corals covered with algae (52%) and sand (24%). Water quality conditions at all three stations still support coral growth, with parameters such as temperature (29-32°C), salinity (31-35 ppt), pH (7.5 ppt), and water clarity (4-8.5 m) within the optimal range. High sedimentation at Stations II and III is the main factor limiting coral growth, caused by community activities such as beach reclamation, pier construction, and hill excavation around the waters. This study provides basic information for the development of strategies for the rehabilitation and management of coral reef ecosystems in Sorong City.

type: item
description: Yubiah Village is a village located in North Ayamaru District, Maybrat Regency, West Papua Province. The community of Yubiah Village is largely engaged in freshwater fish farming, and one of the main cultured species is Nile tilapia. This fish is chosen not only because it is easy to cultivate but also because it has good marketability. Freshwater sources in Yubiah Village are abundant, making freshwater aquaculture easy to carry out. The purpose of this study was to determine the effect of silk algae (Chaetomorpha sp.) as an alternative feed on the growth and survival of Nile tilapia. The research was conducted from October to November 2022 in Yubiah Village, North Ayamaru District, Maybrat Regency, West Papua Province. This study used a Completely Randomized Design (CRD) consisting of three treatments and one control. The results of the study led to the following conclusions: The measurement of absolute weight gain of Nile tilapia showed that the best growth occurred in Treatment C with 80 grams of silk algae as an alternative feed, followed by Treatment B with 60 grams, and Treatment A with 75 grams, while the lowest growth was obtained in Treatment D (without silk algae). The highest survival rate of Nile tilapia was found in Treatment C (28 grams), where fish were given a higher amount of silk algae three times a week. This was followed by the other treatments.

Metode penelitian yang digunakan yaitu metode transek garis dan transek kuadrat kemudian di analisis. Hasil yang didapat adalah 6 jenis bivalvia, yaitu Polymesoda erosa yang terdapat pada stasiun I (15), II (23) dan III (1), Saccrostrea echinata yang terdapat pada stasiun II (50), Anadara granosa yang terdapat pada stasiun III (42), spesies yang belum dketahui terdapat pada stasiun III (3), Saccostrea cucullata yang terdapat pada stasiun III (30) dan Pilsbryoconcha exilis yang hanya terdapat pada stasiun II (1). Nilai kepadatan yang paling tinggi yaitu berjenis Saccostrea echinata dengan kepadatan mutlak 3,33 dan kepadatan relatif 67,56. Indeks keanekaragaman komunitas bivalvia berkisar antara 0–0, 52. Kisaran nilai tersebut menggambarkan bahwa komunitas bivalvia di kategorikan rendah. Indeks keseragaman yang di peroleh yaitu 0–0,51. Hal ini di kategorikan rendah. Indeks dominasi berkisar antara 0,0001–1. Kesimpulan yang di dapat yaitu, telah ditemukan 6 jenis bivalvia. Dari setiap jenis yang ditemukan, diperoleh kepadatan tertinggi pada jenis Saccostrea echinata. Keanekaragaman komunitas bivalvia berada dalam kondisi tidak stabil (parameter lingkungan dan substrat kurang mendukung). Indeks keseragaman yang di peroleh rendah artinya jenis bivalvia yang ditemukan pada tiap stasiun relatif seragam (variasi jenis yang ditemukan sangat rendah). Nilai dominasi mendekati 1 (C <0.5), mengindikasikan bahwa terdapat organisme tertentu yang mendominasi seperti Polymesoda erosa pada stasiun I saccostrea echinta pada stasiun II dan Anadara granosa pada stasiun III.
