Abstract

Taman Nasional Teluk Cenderawasih (TNTC) memiliki potensi karang sebanyak 145 jenis dari 15 famili, dan tersebar di tepian 18 pulau besar dan kecil. Namun kondisi ekosistem terumbu karang di TNTC mulai terancam akibat fenomena alam dan aktifitas manusia. Penelitian ini bertujuan untuk mengetahui kondisi tutupan karang di TNTC berdasarkan bentuk pertumbuhan (lifeform) karang. Penelitian dilakukan dengan metode Point-Intercept Transect (PIT) pada Bulan Mei 2012, dengan pengambilan data terumbu karang per titik (point) sepanjang transek. Penempatan garis transek dilakukan pada 30 stasiun penelitian pada kedalaman 9 - 10 meter. Hasil penelitian menunjukan bahwa persen tutupan karang berdasarkan bentuk pertumbuhan (lifeform) karang hidup berkisar 44 %, karang mati 15%, pasir 31 %, alga 8% dan OT (others) 2%. Kisaran persentasi tutupan karang hidup antara 31 - 50 % sehingga dikategorikan kondisi sedang. Kondisi tutupan karang tidak jauh berbeda antara zona larang tangkap dan zona tangkap. Penelitian ini mengindikasikan pula bahwa diperlukan pengawasan pada zona larang tangkap karena masih ada masyarakat yang menangkap ikan menggunakan alat tangkap yang merusak di TNTC.

Abstract

The presence of skipjack fish resources in a fishing area is related to the suitability of the environmental conditions of the waters. This study aims to examine the relationship of sea surface temperature (SPL) to skipjack catches and the characteristics of skipjack catches in Manokwari waters. Data, both catch data and sea surface temperature data, are collected through field surveys by following fishing operations. Furthermore, the data were analyzed descriptively using graphs and mathematically like von Bertalanffy's growth model. The results of this study found that the very small variability of SPL could not explain the variation in the volume of fishermen's catches in Manokwari waters. However, a high SST during the May - August 2013 period is thought to affect the size of the skipjack caught, where the average size of the fish caught inhabited areas near sea level. In addition, the growth of skipjack fish in Manokwari waters is relatively fast with a growth coefficient of 0.42 per year1 and natural mortality between 0.79 per year and 0.81 per year.

Abstract

The implementation of the fisheries moratorium has an impact on the shrimp industry, namely the cessation of shrimp fishing operations and termination of employees of some shrimp companies in the West Papua Province. The aim of this research is develop a shrimp fisheries management strategy at West papua Province after the end of the moratorium on fisheries so that the shrimp industry can contribute to job creation and increase local revenue. SWOT analysis is used to identify internal and external factors as the basis for the shrimp fisheries policy direction. Recommended strategies for managing Shrimp fisheries; 1) Increasing awareness of coastal communities towards environmental sustainability. 2) Optimizing the productivity of small-scale capture fisheries through improving the quality of fishermen's human resources. 3) Strict law enforcement and improvement of community based fish resource utilization monitoring systems, including improving the quality of HR supervisors. 4) Development of capture fisheries infrastructure, including fuel supply logistics systems. 5) Increased cooperation in fishing business through partnership programs, to ensure the sustainability of operational costs, and the development of business investment. 6) Development of value-added capture fisheries for the welfare of fishermen's income.

Abstract

Skipjack tuna (Katsuwonus pelamis) has high economic value and opportunities for local and export market demand. The present study aims to investigate growth and exploitation status of the resource. Data collection was carried out in April-August 2021 by collecting catch data from fishermen at four fish landing sites in Manokwari. Skipjack tuna caught from the fishermen were caught in the waters around Manokwari. The size of skipjack tuna measured ranged between 260 mm and 760 mm, with an average monthly size ranging between 540 mm and 595 mm. The relationship between total length and body weight of skipjack tuna followed the equation W = 0.00006L2.7702, where the b value of 2.7702 indicates that the growth pattern of skipjack tuna (K. pelamis) is negative allometric. The growth model using the von Bertalanffy model, found asymptote length (L∞) of 792.75 mm, growth rate (K) of 0.75 year-1 and theoretical age (t0) of -0.0254 years. The total mortality (Z) was 1.32 yr-1. Natural mortality (M) was 0.61 yr-1. The mortality due to capture (F) was 0.71 yr-1. The exploitation rate of 0.54 indicated that the exploitation rate of skipjack tuna in the waters around Manokwari has slightly exceeded the optimum utilization rate. The spawning potential ratio (SPR) value was 16%, which was less than the lower reference point (20%).

Abstract

The waters of Bintuni Bay have abundant natural resources, especially aquatic biota. One of the aquatic biota with high economic value is the Jerbung shrimp (Penaeus merguiensis). Currently, information about the biological aspects of shrimp in the waters of Bintuni Bay is still very lacking. Specifically, the aim of this research is to examine the size structure, first caught size (L50%), infinity size (L∞), growth patterns, condition factors and gonad maturity level (TKG) of Jerbung shrimp in the waters of Bintuni Bay. The research method used is the survey method. The research was carried out from March to April 2023. The results showed that the average carapace length and weight of male shrimp were 4.6 cm and 14.8 gr. Meanwhile, the average shell length and weight of female shrimp are 5.4 cm and 25.8 grams. The L50% value of male and female shrimp is 5.3 cm and 5.8 cm, the ½ L∞ value of male and female shrimp is 3.4 cm and 3.5 cm. If L50% > ½ L∞ means the size of the shrimp caught is quite large. The growth pattern of male and female shrimp is negative allometry (b = 0.1035 and b = 0.7424). The condition factor values for male and female shrimp are 0.31 and 1.73. The results of TKG observations showed that 75.2% of female shrimp were in TKG I and II, meaning that 50% of the shrimp caught had not yet reached TGK III and IV at the time of the research.
