Abstract

The salted fish processing industry was one of the small and medium-sized business sectors that played an important role in supporting the economy of coastal communities. Salted fish products not only have a relatively high economic value, but also increase the durability of marine catches through traditional preservation processes. However, amidst fairly broad market opportunities, salted fish processing business actors often faced various challenges, especially regarding production cost efficiency, raw material price transmission, and income instability. This study analysed production costs, revenues, and profits from salted fish processing. The method used in this study was the survey method. Based on the results of the research that had been conducted, it was found that the average cost incurred by salted fish entrepreneurs was IDR 47,702,088 per month, with revenues of IDR 56,612,500 per month. The average profit was approximately IDR 8,910,412 per month

Abstract

The exponential growth of environmental challenges, particularly those affecting water resources, necessitates innovative technological interventions beyond conventional approaches. This review explores the transformative potential of deep learning technologies in water quality management across different scales from controlled laboratory environments to complex oceanic systems. By analyzing recent developments, we identify how neural networks, especially convolutional and recurrent architectures, have revolutionized water quality parameter prediction, anomaly detection, and ecosystem monitoring. Integrating multi-modal data streams with advanced algorithms has enabled unprecedented predictive accuracy and real-time assessment capabilities, transforming reactive monitoring systems into proactive management frameworks. Despite significant progress, challenges remain in data standardization, model interpretability, and the practical deployment of these technologies in resource-constrained settings. This review critically assesses current research trajectories and identifies promising avenues for future development, emphasizing the importance of interdisciplinary collaboration in translating laboratory innovations to large-scale implementation for safeguarding our most precious resource

Abstract

Raising striped catfish (Pangasianodon hypophthalmus) in dark conditions with low salinity (5 ppt) can support growth but may also cause stress and affect blood health. Adding Cosmos caudatus leaves, which contain natural bioactive compounds, in fish feed could offer a natural way to help boost the immune system. This study aimed to understand the hematological response of fish toward the C.caudatus enriched feed provision. The fish were reared for 60 days in 5 ppt salinity water and under a controlled photoperiod. There were four treatments: control (no C.caudatus) T1, T2 and T3 (10 g, 20 g, and 30 g of C.caudatus leave powder in 1 kg of feed). Parameters observed were red and white blood cell number, hemoglobin, hematocrit and glucose concentration, phagocytic activity, leukocrit, and types of white blood cells. Results showed that the T1 group significantly improved the ability of red blood cells, hemoglobin, hematocrit, and phagocytosis. Survival rates were high and showed no significant differences between treatments, suggesting that C.caudatus up to 30 g/kg is safe. Based on these findings, a dose of 10 g/kg can be recommended as an effective natural feed additive to help improve the health and immune system of P.hypopthalmus cultured in controlled rearing conditions

Abstract

This research was conducted in Bangko District, Rokan Hilir Regency, Riau Province. This research aims to analyse the sustainability status of small-scale capture fisheries and leverage attributes that support their sustainability in the future. The method used in this research is a survey method with a quantitative approach and the determination of respondents is carried out randomly purposive sampling with the consideration that the respondents taken were two fishermen group leaders, one community leader, one fisheries instructor, one academic, one village official, two people from the Fisheries and Maritime Service, and one fishermen cooperative. The public criteria selected in this study to collect the primary data were seven people, namely, fishermen. The number of public respondents selected came from villages/districts, so the total number of respondents was 16. Based on research results sustainability status small-scale capture fisheries show a sustainability index with an average value of 51.65 or in the range 50-75 which is classified as quite sustainable and the leverage attributes from the five dimensions that are the most sensitive and have high leverage in influencing the sustainability status of capture fisheries include fishing time, nature ownership of fishing facilities, type or nature of fishing gear, fishermen's education level, and fisheries management plan (RPP).

Abstract

The availability of bivalve spat has a strategic role in ensuring the sustainability of bivalve communities in aquatic ecosystems. This study aims to determine the species, abundance, and timing of bivalve spat settled on the basic substrate of mangrove forest in the intertidal zone of Rupat Island. This research was conducted in June - October 2017. The research was located in the intertidal zone, which is divided into three subzones: upper, middle, and lower. To collect spat bivalve using a net collector, like a tray. This research method was a survey method. The results showed that the bivalve spat had three types: Pilsbryoconcha exilis spat, Polymesoda expansa, and Pharella acutidens. The average abundance is 4.06 ind/m2; the highest abundance of bivalve spats was at the lower subzone, 2.13 ind/m2. The lower subzone was adjacent to the sea and was affected by the tides. From the monthly sampling, October was the highest, with an average abundance of 1.2 ind/m2. Spat catches in June-October were low, and the possibility of a recruit peak of bivalve spat had not happened yet.
