Abstract

The terubuk fish (Tenualosa macrura) is an endemic species that holds high economic value and significant socio-cultural importance for the people of Riau, Indonesia. However, excessive fishing pressure and estuarine habitat degradation have drastically reduced its population. This study aims to map and synthesize existing scientific knowledge related to the conservation and management of the terubuk fish through a scoping review approach. A total of 38 documents were examined, of which 34 met the inclusion criteria based on the PRISMA-ScR guidelines. The analyzed literature was categorized into six major thematic areas: bioecology, socio-economics, institutional aspects, legal frameworks, cultural values, and environmental factors. The synthesis reveals heavy pressure on fish stocks, high economic vulnerability among small-scale fishers, weak law enforcement, and a declining role of local wisdom in conservation practices. These findings emphasize the urgency of developing an integrated management strategy that combines ecological science, socio-economic conditions, and the cultural values of coastal communities. Such an approach could serve as the foundation for designing more adaptive and effective policies to ensure the long-term sustainability of the terubuk fish population in Riau waters.

Abstract

Sektor perikanan merupakan sektor yang strategis untuk meningkatkan devisa negara dalam pembangunan nasional. Namun, dikarenakan munculnya wabah Corona Virus Disease 19 (Covid-19) bidang perikanan tangkap terkena dampak pandemi tersebut. Pelaku usaha perikanan yaitu nelayan, pedagang ikan skala kecil (pedagang retail), pemilik UMKM terkena imbas dari pandemi Covid-19. Pendapatan para pelaku usaha perikanan menurun karena permintaan pasar yang menurun sehingga harga ikan juga menurun. Pelaku usaha perikanan lebih sulit dalam memasarkan produk perikanannya. Maka dari itu, terdapat sebuah solusi untuk mengatasi permasalahan tersebut yaitu aplikasi jual beli ikan, baik ikan segar maupun ikan olahan yang mampu dijangkau oleh masyarakat luas berbasis online. Aplikasi ini merupakan sebuah aplikasi jual beli ikan secara online yang menghubungkan penjual dengan konsumen secara langsung dengan sistem pengantaran dengan driver. Perancangan aplikasi menggunakan metode Software Development Lifecycle (SDLC) Waterfall yang terdiri dari enam tahap yaitu analysis, design, implementation, testing, deployment, dan maintainance. Aplikasi FO-KLIK bersifat real-time yaitu mampu melakukan pembaharuan secara otomatis dalam sistem. Fitur pada FO-KLIK yaitu beli, co-book, diskusi, berita, informasi gizi, akun, aktivitas. Aplikasi yang sederhana, praktis, mudah dan nyaman dioperasikan oleh user.

Abstract

Understanding the swimming behavior and patterns of tambakan fish (Helostoma temminckii) is crucial for advancing fishing technology. This study aimed to identify the effect of current on the swimming speed behavior of Helostoma temminckii within a mini flume tank. Experiments were conducted using different current speeds to observe three categories of swimming speed: sustained swimming speed, prolonged swimming speed, and burst swimming speed. Observations were performed using video recordings to analyze tail beat frequency and amplitude, as well as the correlation between these variables and the fish's swimming speed and endurance. The results revealed that current speeds had a significant influence on the swimming performance of Helostoma temminckii. The maximum sustained swimming speed ranged from 1.61 to 2.21 BL/s, while prolonged swimming occurred within 1.61–6.98 BL/s, with swimming durations between 15 seconds and less than 200 minutes. Burst swimming speed reached up to 6.20 body lengths per second (BL/s) and lasted under 15 seconds. Several factors were found to influence the swimming behavior of Helostoma temminckii, including a strong negative correlation between swimming speed and endurance (R² = 0.8259). Moreover, a positive correlation was observed between tail-beat frequency and swimming speed (R² = 0.8852) and between tail-beat amplitude and frequency (R² = 0.9454). These findings have significant implications for designing more efficient and selective fishing gear by taking into account fish physiology. The study provides a critical foundation for the development of environmentally friendly fishing technologies and a better understanding of the swimming behavior of native fish species.
