Abstract

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.

Abstract

This community service activity focused on developing feed production techniques using local raw materials for mud crab farmers in Madak Belek Hamlet, Sekotong District. The main challenge faced by farmers is the high cost of commercial feed, which reduces profit margins. In fact, the area is rich in underutilized nutrient-rich local resources such as trash fish and seafood processing by-products. A participatory approach was applied, including observation, socialization, demonstration, hands-on training, and evaluation. The training emphasized feed formulation and the application of 5% wheat gluten as a binder, which had been proven in preliminary studies to enhance feed stability in water. The results showed an improvement in participants’ knowledge and skills in processing local ingredients into quality feed. The expected impacts include reducing dependence on commercial feed, lowering production costs, and improving the efficiency and sustainability of mud crab farming. For further optimization, feed performance testing on crab growth and economic feasibility analysis are required.

Abstract

Aquaculture continues to expand globally, requiring natural and sustainable feed additives to enhance fish growth and meat quality. Cinnamon (Cinnamomum burmannii) leaf extract contains diverse bioactive compounds, including cinnamaldehyde, flavonoids, polyphenols, and terpenoids, which possess antioxidant, antimicrobial, and growth-promoting properties. This review aims to summarize scientific evidence on the effectiveness of cinnamon leaf extract in improving growth performance and meat quality of farmed fish. A systematic literature review was conducted by analyzing 41 scientific publications obtained from Google Scholar, ProQuest, and Elsevier. The reviewed studies consistently showed that supplementation of cinnamon leaf extract or powder at doses ranging from 0.25–1% in fish feed enhances growth parameters such as Specific Growth Rate, feed efficiency, protein retention, and biomass in species including barramundi, Nile tilapia, common carp, and striped catfish. In addition, the extract significantly improves meat quality by reducing body and meat fat content, enhancing texture, increasing protein levels, and improving sensory attributes such as taste and fillet color. These improvements are attributed to the metabolic, antioxidant, and lipid-modulating mechanisms of the phytochemicals present in cinnamon leaves. Overall, cinnamon leaf extract demonstrates strong potential as a natural, environmentally friendly feed additive that supports both productivity and product quality in modern aquaculture systems.

Abstract

Feed stability is a crucial factor in aquaculture, as it affects both the physical integrity of the feed and its acceptance by aquatic species. For Monopterus albus (swamp eel), maintaining feed stability while ensuring palatability is vital for optimal growth and health. This study aimed to evaluate the effects of different binder types and concentrations on the stability and acceptability of pasta feed for Monopterus albus (swamp eel). Seven binders—gelatin, gluten, CMC, chitosan, alginate, guargum, and carrageenan—were tested at 0%, 10%, 15%, and 20% concentrations using a completely randomized design. Feed disintegration and breakdown times, along with feeding behavior, were analyzed using non-parametric tests. Gelatin, CMC, and chitosan significantly improved feed stability (p < 0.05), maintaining cohesion for over 40 minutes. Gelatin at 10% concentration yielded optimal results, balancing water resistance and palatability. Behavioral observations showed that gelatin-based feeds were most preferred, with increased feeding frequency and consumption. When combined with natural attractants such as worms and snails, gelatin feeds enhanced intake rates. These outcomes indicate that protein-based binders, particularly gelatin, offer superior mechanical and nutritional advantages compared to polysaccharide alternatives. Gelatin’s dual role as a binder and nutritional enhancer provides a promising strategy for sustainable aquaculture feed development.

Abstract

Ekosistem terumbu karang, padang lamun, dan mangrove berperan penting dalam menopang keanekaragaman biota laut, termasuk ikan hias bernilai ekonomi seperti ikan badut. Tingginya permintaan pasar terhadap ikan badut berpotensi meningkatkan eksploitasi dari alam, sehingga diperlukan upaya pengelolaan berkelanjutan. Salah satu pendekatan yang diterapkan adalah restocking menggunakan ikan hasil budidaya yang dipadukan dengan edukasi kepada masyarakat dan pemangku kepentingan. Kegiatan pengabdian kepada masyarakat ini melaporkan restocking sekitar 2.000 ekor ikan badut hasil budidaya Balai Perikanan Budidaya Laut (BPBL) Lombok di Pantai Elak-Elak, Sekotong Barat, Lombok Barat pada 24 Oktober 2025. Program ini melibatkan mahasiswa PKL (Praktik Kerja Lapang) dan KKN-KKB (Kuliah Kerja Nyata-Kegiatan Kampus Berdampak) Universitas Mataram, masyarakat lokal, dan siswa sekolah dasar. Metode pelaksanaan mencakup budidaya ikan, survei lokasi, proses pengemasan beroksigen, serta penebaran secara kolaboratif. Hasil kegiatan menunjukkan keberhasilan penebaran ikan ukuran 5–7 cm dengan teknik pengemasan sekitar 10 liter per kantong berisi 50–70 ekor, serta terlaksananya kegiatan edukatif dan partisipatif. Namun, tidak tersedia data monitoring pascapenebaran maupun evaluasi terstruktur, sehingga dampak ekologis belum dapat diukur secara pasti. Kegiatan ini berpotensi mendukung konservasi ikan badut dan meningkatkan kesadaran masyarakat terhadap pentingnya menjaga ekosistem terumbu karang.
