Abstract

The coastal area of Alue Naga, Banda Aceh City, is characterized by high fisheries potential and increasing pressure on estuarine resources due to small-scale fishing activities. One of the fishing gears commonly operated by local fishers is the anco, a traditional rectangular lift net deployed in estuarine waters. This study aimed to examine the catch composition, species dominance, and diversity associated with anco fishing gear in the Alue Naga River estuary, Banda Aceh. The research applied an experimental fishing approach with direct participation in fishing operations, complemented by the collection of primary and secondary data. Catch composition was assessed based on species abundance and biomass, while fish community structure was evaluated using the Shannon–Wiener diversity index (H′) and the Simpson dominance index (C). A total of 18 fish species were recorded during the study period. Greenback mullet (Chelon subviridis) was the most abundant species, contributing 60 individuals (0.448%) and a total biomass of 1,651 g (0.631%). In contrast, rabbitfish (Siganus guttatus) was the least abundant species, represented by a single individual (0.007%) with a biomass of 4 g (0.002%). The Shannon–Wiener diversity index (H′ = 2.039) indicated a moderate level of species diversity, whereas the Simpson dominance index (C = 0.236) suggested low dominance within the fish assemblage. Overall, the results indicate that anco fishing gear captures a relatively diverse fish assemblage with a balanced species composition and no clear dominance by a single species. These findings provide baseline ecological information that may support the development of sustainable management strategies for small-scale estuarine fisheries in the coastal waters of Banda Aceh.

Abstract

The utilization of fish processing by-products represents an important strategy to improve production efficiency and support zero-waste principles. Milkfish (Chanos chanos) bone by-products, generated from deboned milkfish processing, have significant potential as a value-added food ingredient. This study aimed to characterize the nutritional composition of milkfish bone powder and milkfish bone floss products and to evaluate their potential calcium contribution to the recommended dietary allowance (RDA) for adults. Bone powder was produced through washing, boiling, oven drying at 60-70°C, grinding, and sieving (80 mesh). Bone floss was prepared through pre-boiling, high-pressure cooking (±121°C for ±2 hours), grinding with spices, and roasting until low moisture content was achieved. The study involved two product treatments, namely milkfish bone powder and milkfish bone floss. The nutritional composition of each product was determined using proximate analysis based on AOAC methods, including moisture, ash, protein, fat, and carbohydrate contents, with all analyses conducted in triplicate. Results showed that bone powder contained 3.52% moisture, 21.50% protein, 10.28% fat, 52.44% ash, and 12.26% carbohydrates, while milkfish bone floss contained 3.30% moisture, 20.82% protein, 23.32% fat, 25.88% ash, and 26.68% carbohydrates. The calculated energy values were approximately 227 kcal/100 g for bone powder and 400 kcal/100 g for bone floss using Atwater factors. Assuming that 30% of total ash represents calcium, bone powder is estimated to contain approximately 15,730 mg calcium per 100 g, theoretically exceeding 100% of the adult RDA (1000 mg/day) with a 10 g serving. Bone powder shows strong potential as a mineral fortification ingredient, while bone floss is suitable as a ready-to-eat high-energy product. These findings demonstrate that simple thermal processing can generate nutritionally competitive products from fish bone waste.
