The tuna loin industry leaves quite a lot of waste in the form of thin meat tether mixed with fiber. Tuna tethers have good development prospects because they can become the main ingredient for making surimi. Surimi is an intermediate product that has a high functional protein content and has been recognized worldwide. Surimi is the raw material for fish jelly products such as dragon leg, meatballs, nuggets, and others. Based on observations, it turns out that tuna tethers have not been optimally utilized to improve the welfare of the community. The North Ambon Island Klasis area community does not know the processing of surimi and its development opportunities into various competitive products. The purpose of this activity is to utilize tuna tether through the application of surimi technology and dragon foot product processing to household wives from several villages on North Ambon Island. The target audience for this activity was 30 household wives from 17 villages in the North Ambon Island Klasis area. The activities were carried out from March to April 2022, consisting of three (3) stages , preparation, implementation of counseling, and training. The results of the paired sample T test show that there is a significant difference in the knowledge of the target audience before and after the implementation of counseling and training on the application of surimi technology and processing surimi into dragon foot products. The average post-test score of 30 participants increased by 59.39% after participating in counseling and training activities on the application of surimi technology and processing surimi into dragon foot products. At the end of the activity, the participants practiced surimi and dragon foot processing trials, showing 90% of the participants were quite skilled in processing the two products.

ABSTRACTUtilizing fishery by-products into products of high economic value is one strategy in diversifying fish-based food. One of the by-products of processing tuna (Thunnus sp.) which has great potential is fish molasses, namely tuna molasses which are small slices of tuna meat from the remaining pieces which cannot be used because the cuts are uneven. This study aims to evaluate the effect of adding tapioca flour and carrageenan flour in various concentrations on the organoleptic characteristics and proximate composition of fish sempol made from tuna fish offcuts (Thunnus sp.). This research used an experimental method with a treatment design consisting of four variations of flour formulation, namely a combination of tapioca flour and carrageenan flour in different ratios. The resulting sempol was then analyzed organoleptically based on appearance, aroma, taste and texture parameters using a hedonic scale involving 19 panelists. Apart from that, the best samples based on organoleptic tests were then analyzed proximately to determine the water, ash, fat, protein and carbohydrate content. The results of the research showed that the combination of 150 g tapioca flour and 50 g carrageenan flour produced sempol with the highest level of panelist acceptance. This product has a more attractive appearance, more distinctive aroma, more favorable taste, and a chewier texture compared to other formulations. Proximate analysis of the best sempol shows that this product has a water content of 63.1%, ash content of 1.6%, fat content of 8.22%, protein content of 6.59%, and carbohydrate content of 20.49%. Keywords : Tuna fish swallow, carrageenan flour, organoleptic analysis, proximate analysis.

Heavy metal contamination in urban aquatic environments represents an important threat to fish health because persistent metals can bioaccumulate and induce structural and functional alterations in vital organs. This study aimed to evaluate the association between lead (Pb), cadmium (Cd), and mercury (Hg) exposure and renal histopathological alterations in common carp (Cyprinus carpio) from contaminated urban waters. A quantitative observational comparative approach was applied by examining fish from contaminated and reference sites. Heavy metal concentrations were determined in water and kidney tissues, while renal alterations were assessed through Hematoxylin–Eosin histopathology and semi-quantitative lesion scoring. Urea and creatinine were evaluated as complementary renal indicators, and correlation analysis was performed to examine associations among metal burdens, tissue damage, and biochemical alterations. Fish from contaminated sites exhibited higher metal accumulation and more severe tubular degeneration, epithelial vacuolation, tubular necrosis, glomerular abnormalities, vascular congestion, and inflammatory responses. Heavy metal concentrations were positively associated with renal damage severity, with cadmium showing the strongest relationship. These findings demonstrate that integrating metal accumulation, renal histopathology, and biochemical indicators provides a comprehensive approach for assessing contaminant-associated fish health and supports common carp as a potential sentinel species for urban freshwater biomonitoring.

Spirulina platensis has considerable potential as a functional fish-feed ingredient because of its high protein content, natural pigments, and bioactive compounds. However, cultivation conditions must be optimized to produce biomass with stable growth, filament integrity, and biochemical quality. This study evaluated the effects of carrageenan concentration in culture media on the physical characteristics, biomass growth, filament morphology, and biochemical composition of S. platensis. A laboratory experiment was conducted using a Completely Randomized Design comprising four carrageenan treatments: 0.00%, 0.05%, 0.10%, and 0.15%, with three independent replications. The measured parameters included pH, temperature, viscosity, biomass density, dry biomass, specific growth rate, biomass productivity, filament length, fragmentation percentage, crude protein, phycocyanin, chlorophyll, and moisture content. Data were analyzed using one-way analysis of variance followed by Duncan’s multiple range test. Carrageenan significantly increased medium viscosity without substantially changing pH or temperature. The 0.10% treatment produced the highest biomass density, dry biomass, specific growth rate, and biomass productivity. It also generated the longest filaments, lowest fragmentation percentage, and highest protein, phycocyanin, and chlorophyll contents. Conversely, the 0.15% treatment reduced growth, filament integrity, and biochemical quality, indicating that excessive viscosity may restrict light penetration, aeration, mixing, and nutrient transfer. The findings demonstrate that 0.10% carrageenan provides the most favorable cultivation conditions among the tested concentrations. This concentration can be considered for producing high-quality S. platensis biomass, although direct feeding trials are required to confirm its digestibility, biological effectiveness, and economic feasibility in aquaculture.

Water quality is a fundamental determinant of fish health, growth, feed efficiency, and survival, particularly in polyculture systems where biological interactions and organic-waste accumulation can increase environmental variability. This study aimed to analyze the relationships between pond-water physicochemical parameters and the health and productivity of Nile tilapia (Oreochromis niloticus) cultured in a polyculture system. A quantitative correlational design was applied over a three-month observation period. Temperature, pH, dissolved oxygen, ammonia, and nitrite were measured routinely using calibrated instruments. Fish health was assessed through hematocrit and leukocyte levels, while productivity was evaluated using final body weight, feed conversion ratio, and survival rate. Data were analyzed using descriptive statistics, correlation analysis, and multiple linear regression. The findings showed that dissolved oxygen and ammonia were the most influential water-quality parameters. Higher dissolved oxygen was associated with better hematological condition, increased final body weight, more efficient feed utilization, and higher survival. Conversely, elevated ammonia was associated with increased physiological stress, reduced growth, poorer feed conversion, and lower survival. Temperature, pH, and nitrite demonstrated weaker relationships but remained important for maintaining environmental stability and supporting fish metabolism. These findings emphasize the importance of integrated water-quality management through regular monitoring, appropriate feeding, adequate aeration, stocking-density control, and organic-waste management. The study provides a practical foundation for adaptive pond management that can improve fish welfare, production efficiency, and the sustainability of Nile tilapia polyculture systems.

The production of high-quality Asian seabass (Lates calcarifer) seed is strongly influenced by environmental management during the larval stage. Water temperature regulates metabolic activity, feeding, digestion, and development, whereas stocking density affects competition, stress, water quality, and survival. This study evaluated the individual and interactive effects of water temperature and stocking density on the growth and survival of Asian seabass larvae cultured in a recirculating aquaculture system. A completely randomized factorial design consisting of three temperature levels and three stocking densities was applied. The nine treatment combinations were independently replicated three times using separate recirculating culture units. Specific growth rate, weight gain, length gain, survival, mortality, size variation, and water-quality parameters were measured during the culture period. Data were analyzed using two-way analysis of variance followed by multiple-comparison testing. Water temperature and stocking density significantly affected larval growth and survival, and a significant interaction occurred between the two factors. The highest individual growth and survival were obtained at 30 °C and 10 larvae/L. However, the combination of 30 °C and 20 larvae/L provided the most balanced operational performance by maintaining high growth and survival while improving tank utilization. Larvae maintained at 32 °C and 30 larvae/L exhibited the lowest growth and survival, the highest mortality and size variation, reduced dissolved oxygen, and greater nitrogenous-waste accumulation. These findings demonstrate that temperature and stocking density should be managed jointly according to RAS treatment capacity. Maintaining an appropriate temperature–density combination can improve larval health, seed-production efficiency, fish welfare, and the environmental sustainability of Asian seabass hatcheries
