Abstract

Tujuan penelitian ini adalah untuk mengeksplorasi struktur dan letak organ dalam tubuh ikan kerapu (Epinephelus sp.). Metode penelitian melibatkan pengamatan visual terhadap karakteristik fisik dan operasi pembedahan pada ikan kerapu, yang kemudian dianalisis untuk mendapatkan pemahaman yang lebih baik. Hasil penelitian menegaskan bahwa ikan kerapu memiliki tubuh yang cenderung oval atau memanjang, dengan kepala besar, beragam jenis sirip, sisik yang beraneka ragam, dan gigi yang tajam. Anatomi ikan kerapu mencakup organ-organ vital seperti hati, usus, lambung, dan insang, yang berperan penting dalam berbagai fungsi tubuh seperti metabolisme, pencernaan, dan pernapasan. Pentingnya pemahaman tentang anatomi ikan kerapu adalah untuk memahami fungsi-fungsi organ tersebut serta berkontribusi dalam upaya konservasi dan manajemen populasi ikan. Dengan pengetahuan yang lebih mendalam tentang anatomi ikan kerapu, diharapkan dapat memperkuat kesadaran akan perlunya pelestarian dan perlindungan terhadap spesies ini.

Abstract

This study aimed to evaluate the effectiveness of using surround nets in increasing the catch of male mackerel in Siofabanua Village, North Nias Regency. In an effort to overcome the low catch of conventional methods, this study investigated the technical and environmental factors that influence the success of surround nets. The research method used a descriptive qualitative approach with field observations, in-depth interviews with fishermen, as well as the study of relevant documents. The results showed that the use of circle nets significantly increased the number and quality of catches, as well as the time and labor efficiency of fishers. The main factors influencing the successful use of circle nets are the condition of the net, placement techniques, and environmental factors such as water depth, food sources, and underwater habitat structure around Siofabanua Village. In addition, weather and seasonal factors also impact catch success. Recommendations include improving net specifications, providing technical training to fishers, and developing policies and regulations that support sustainable fisheries. In conclusion, the use of circle nets has the potential to be an effective and environmentally friendly technology in increasing the productivity of local fisheries in Siofabanua Village, as well as supporting sustainable fisheries practices and marine resource conservation

Abstract

This study explores the culture of tubifex worms (Tubifex sp.) as natural feed to enhance the growth of catfish larvae (Clarias sp.). Tubifex worms are known for their high nutritional content, with protein levels reaching 55-66%, crucial for larval growth. The culture activity was conducted in Bawosalo’o, Nias Barat, from May 2 to May 31, 2025. Observations showed an increase in larval length from 0.72 cm on the first day to 1.1 cm by the seventh day, with a survival rate of 60%. Water quality, including temperature and pH, was well-maintained, supporting larval survival. Additionally, using tubifex worms as natural feed not only improved growth but also contributed to sustainable and environmentally friendly aquaculture practices. This research concludes that tubifex culture is an effective method for catfish larvae cultivation and recommends enhancing knowledge of breeding techniques and water quality management.

Abstract

This research explores innovative strategies in the management of marine fisheries resources and their impact on the welfare of fishers in Siofabanua Village, North Nias. Using a holistic and multidisciplinary approach, we analyzed aspects of the marine ecosystem, fishers' socioeconomic dynamics, and fisheries management policies. The analysis showed that the implementation of innovative strategies significantly improved fishers' income, access to education and health, and their quality of life. Government support, community involvement, and fishers' capacity also play an important role in the success of innovative strategies. This research provides recommendations for governments, non-governmental organizations and communities to strengthen policies, funding, institutions and cooperation to maintain the sustainability of marine fisheries resources and improve fishers' welfare. This article not only provides an in-depth understanding of the challenges faced by fishing communities in Siofabanua Village, but also proposes innovative solutions to improve their welfare. It is hoped that this article can serve as a guide for practitioners, policy makers, and communities in maintaining the sustainability of marine fisheries resources and the welfare of fishers in coastal areas.

Abstract

Pertumbuhan populasi dunia dan kebutuhan pangan yang semakin meningkat merupakan tantangan global kompleks. Untuk mengatasinya, inovasi teknologi akuakultur berkelanjutan, seperti sistem akuaponik, telah menjadi fokus utama dalam upaya memenuhi kebutuhan pangan yang meningkat. Sistem akuaponik mengintegrasikan budidaya ikan dengan pertumbuhan tanaman secara terintegrasi, menciptakan siklus alami di mana ikan menghasilkan limbah yang diperlukan sebagai sumber nutrisi bagi tanaman, sementara tanaman membersihkan air untuk ikan. Dalam jurnal ini, kami membahas pemanfaatan sistem akuaponik untuk meningkatkan produksi ikan dan tanaman secara berkelanjutan. Sistem akuaponik menawarkan berbagai manfaat, antara lain efisiensi penggunaan air yang tinggi, pengurangan limbah, dan peningkatan produktivitas. Penelitian ini dilakukan melalui tinjauan pustaka terhadap artikel ilmiah, jurnal, dan publikasi terkait inovasi teknologi akuakultur berkelanjutan dan pemanfaatan sistem akuaponik. Data dan informasi yang diperoleh dianalisis dan disajikan untuk mendukung tujuan penelitian ini. Dalam hasil dan pembahasan, kami menjelaskan prinsip dasar dan manfaat akuaponik, serta faktorfaktor yang mempengaruhi produksi ikan dalam sistem akuaponik, seperti ketersediaan nutrisi, kualitas air, suhu lingkungan, kepadatan ikan, dan manajemen pakan. Diharapkan bahwa penelitian ini memberikan panduan dan pemahaman yang lebih baik tentang potensi dan keuntungan penggunaan sistem akuaponik dalam konteks akuakultur berkelanjutan Kata kunci: Akuakultur Berkelanjutan, Akuaponik, Inovasi Teknologi, Produksi Ikan dan Tanaman
