Abstract

Ikan pari kekeh (Rhynchobatus spp.) adalah salah satu jenis ikan yang dilindungi dan memiliki nilai ekonomis tinggi. Tingginya harga jual pari kekeh berdampak pada meningkatnya usaha tangkap serta kerusakan habitat pari kekeh yang hidup berasosiasi dengan ikan target nelayan. Informasi terkait aspek biologi sangat berguna bagi pembuat kebijakan dalam memanfaatkan sumberdaya yang berkelanjutan. Tujuan penelitian ini adalah memberikan informasi mengenai nisbah jenis kelamin ikan yang tertangkap, sebaran ukuran panjang, dan potensi sumber daya ikan pari kekeh (Rhynchobatus spp.) di perairan Aceh Jaya. Pengumpulan data pendaratan pari kekeh meliputi jenis kelamin, panjang total dan jumlah trip melaut pada periode tahun 2017-2021. Jumlah tangkapan total pari kekeh yang didaratkan sebanyak 191 ekor yang terdiri dari Spesies Rhynchobatus australiae sebanyak 133 ekor (69,63%), Rhynchobatus laevis sebanyak 55 ekor (28,80%) dan Rhynchobatus springeri sebanyak 3 ekor (1,57%). Ukuran pari kekeh yang tertangkap didominasi oleh ikan muda (immature), yaitu berada pada kelas panjang 65-86cm. Nisbah jenis kelamin ikan jantan dan betina 1:2,41 menunjukan hasil yang tidak seimbang. CPUE menunjukan nilai rata-rata yang fluktuatif, hubungan hasil tangkapan dengan upaya yaitu positif signifikan dengan persamaan linear y = 0,6687x + 1,6338 dengan R2 =0,9706 atau r = 0,9852 yang dapat diartikan bahwa setiap peningkatan upaya berbanding lurus dengan peluang pari kekeh yang tertangkap.Wedgefish (Rhynchobatus spp.) is one of the protected fish species that has high economic value. The high selling price of the wedgefish has an impact on increasing fishing efforts and damage to the habitat of the wedgefish that live in association with the target fish of fishermen. Information related to biological aspects is beneficial for policymakers in utilizing sustainable resources. The purpose of this study was to provide information on the sex ratio of wedgefish, length distribution, and potential resources of the wedgefish in the waters of Aceh Jaya. The wedgefish landing data collection included sex, total length, and the number of fishing trips from 2017 to 2021. The total number of wedgefish obtained was 191. The number consisted of 133 fishes from the Rhynchobatus australiae (69.63%), 55 fishes from Rhynchobatus laevis (28.80%), and 3 fishes from Rhynchobatus springeri (1.57%). Most of the wedgefish caught were immature fish with a size of 65-86 cmTL. The sex ratio of male and female fish was 1:2.41, showing unbalanced condition between males and females. CPUE aspect showed a fluctuating average value. The relation between the catch and effort was positive and significant with alinear equation of y = 0.6687x + 1.6338 with R2 = 0.9706 or r = 0.9852, meaning that increasing fishing effort was proportional to the possibility of a wedgefish being caught.

Abstract

Fisheries management area (FMA) 712 or the Java Sea is one of Indonesia's most extensively exploited waters and is renowned forits productivity as a fishing ground. The dynamics of fish resource utilization in these waters are indicative of the high complexityof the extant fisheries system, with small pelagic fish resources having been subject to exploitation through various changes in geartechnology thus increasingly competitive fishing grounds. Therefore, there is a need data on current distribution and catch trend ofsmall pelagic fisheries in the Java Sea through the use of fishery dependent data as an integral part of sustainable fisheriesmanagement. The present study utilizes fishing logbook data to analyze the status of small pelagic fish resource utilization in theJava Sea. The study utilized fishing logbook data downloaded from the database application of the Fishing Logbook InformationSystem of the Indonesian Ministry of Marine Affairs and Fisheries, covering the period from 2018 to 2022. The subsequentprocessing of catch data was conducted using Microsoft Excel software, whereas the distribution of fishing areas was analyzed usingQGIS tools. The analysis revealed a tendency for a decline in the catch of small pelagic fisheries for the Indian Mackerel(Rastrelliger kanagurta), Short Mackerel (Rastrelliger brachysoma), Fringescale Sardinella (Sardinella fimbriata) and ShortfinScad (Decapterus macrosoma). Only Yellowstripe Scad (Selaroides leptolepis) showed an increased catch trend in that period. Itwas further observed that the fishing grounds of all fish species remained consistent on an annual basis. The Shortfin Scad fishinggrounds were found to be uniformly dispersed within FMA 712, exhibiting a tendency to congregate along the Java Sea border withBorneo waters. Short Mackerel have been observed to be frequent in fishing grounds of the eastern to western Java Sea. In contrast,Indian Mackerel have been noted to be more prevalent in the waters of South Borneo and the western Java Sea. The distribution ofYellowstripe Scad fishing grounds appears to be uniform within FMA 712. Fringescale Sardinella fishing grounds have beenidentified as being predominantly concentrated in the western Java Sea and in Borneo waters.

Abstract

The southwest coast of Madagascar is home to small-scale Coral Reef Fisheries (CRFs), a vital activity for livelihoods and the local economy of the fishermen community. Understanding all about the components of this CRFs, the nature of their interactions and the resulting outcomes is crucial for designing policies that promote equitable and sustainable fisheries. This research aims to apply the Social-Ecological Systems (SES) framework and network analysis to assess the SES structure and the characteristics of Ranobe Bay CRFs, Madagascar. This research was carried out from September to October 2024, requiring primary data from field observations, interviews with respondents, and secondary data from literature studies. The Socio-Ecological Network Analysis (SENA) was used to analyze the connectivity of the CRFs in this region. The research findings of the SENA results showed that this fishery is heavily centered around the fishermen's community: the Masikoro and the Vezo as the main actors of this activity. Nevertheless, according to the cluster value analysis, the findings highlight a high number of clusters showcasing a low connectivity and less compact SES structure. Ranobe Bay's CRFs' sustainability depends on fishermen's central connectivity within the network, which can be strengthened through improved policies and management to ensure effective governance.
