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

The development of stable and palatable artificial feed remains a major challenge in the culture of Asian swamp eel (Monopterus albus), mainly due to the continued reliance on natural feeds such as earthworms. This study evaluated the effects of different binder types and concentrations on feed stability and eel feeding responses using pasta feed formulations combining commercial pellets and earthworms. The experiment applied a factorial Completely Randomized Design involving four binder types—gelatin, gluten, carboxymethyl cellulose, and chitosan—with several concentration levels (10%, 15%, and 20%) including a control without binder. Feed stability was assessed through water immersion tests measuring feed disintegration and structural deformation, while feeding behavior was evaluated through approach frequency, consumption, rejection behavior, and feeding latency. The results showed that binder incorporation significantly improved feed stability compared with the control treatment. Chitosan at a 10% concentration provided the best resistance to feed breakage, whereas 10% of carboxymethyl cellulose, gluten, and chitosan, maintained feed structure effectively during immersion. Binder-containing feeds, particularly those with gelatin, gluten, and chitosan, exhibited no different in feeding acceptance. These findings demonstrate that optimizing binder type and concentration can improve feed stability and feeding efficiency, supporting the development of more sustainable artificial feeds for swamp eel aquaculture.

Abstract

Garra rufa fish from the Cyprinidae family are known as "doctor fish" in the context of health tourism due to their use as an alternative medicine to help cure various skin diseases. Garra rufa are benthic fish or freshwater bottom dwellers that naturally live in rocky rivers and feed on microscopic organisms. Garra rufa culture in Indonesia is still limited due to the lack of technical information regarding cultivation aspects such as water quality management, feeding, and maintenance techniques. The purpose of this activity is to determine the Garra rufa culture techniques with different feeding rate on their growth and survival rate. The method applied in this research was a descriptive experimental method using two different percentages of feeding rate, namely 3% and 5% of the fish's body weight, kept in an aquarium for 21 days. The parameters observed were growth and survival rate. The results obtained were Garra rufa maintained with a 5% feeding rate had higher growth but were not more efficient when viewed from their higher FCR values. The survival of both feeding rate treatments was at high figures, namely 87% and 95%.

Abstract

Motile Aeromonas Septicemia (MAS) caused by Aeromonas hydrophila, is a major bacterial disease in Nile tilapia aquaculture and result in substantial production losses. The excessive use of antibiotics for disease control has raised concerns regarding antimicrobial resistance and environmental contamination, thereby necessitating safer and more sustainable alternatives. This study evaluated the immunostimulatory effect of dietary supplementation with citronella (Cymbopogon nardus) powder combined with probiotics on Nile tilapia challenged with MAS. A completely randomized design was employed using four dietary treatments: a basal diet without supplementation and three experimental diets supplemented with 15 mL of probiotics and citronella powder at doses of 7.5, 10, or 12.5 g per kg of diet (PC-7.5, PC-10, or PC-12.5). Fish were fed the experimental diets for 14 days prior to challenge with A. hydrophila (107 CFU/mL), followed by a post-challenge recovery period. Recovery rate, survival rate, and hematological parameters were assessed. The result indicated that dietary supplementation, particularly PC-7.5, tended to improve recovery and survival rates, although these differences were not statistically significant (P > 0.05). In contrast, hematological parameters were significantly influenced by the dietary treatments (P < 0.05), with PC-7.5 diet producing higher hematocrit, hemoglobin, and leukocyte values, as well as faster hematological recovery following infection. These findings suggest that dietary supplementation with 7.5 g of citronella powder per kg of diet combined with 15 mL probiotics effectively enhances immune response and support disease resistance in Nile tilapia, representing a promising and environmentally friendly strategy for MAS control in aquaculture.

Abstract

Tourism has great potential to drive economic growth and act as a catalyst for the development of other sectors, and one promising destination in Banjarbaru, South Kalimantan, is Danau Seran, a notable example of transformation from a former mining site operated by PT Galuh Cempaka into a nature-based tourist attraction offering activities such as boating, fishing, and enjoying scenic views. This study aims to formulate a sustainable water resource management strategy to support ecotourism development at Lake Seran, Banjarbaru, using a typology analysis of strategic variables through the MICMAC method. Water resource management in this area is challenging because Lake Seran was formed from a former mining area. The approach used in this study is a prospective structural analysis with in-depth interviews and MICMAC software input to analyze the relationship between variables that influence water management and ecotourism development. The results show that variables such as water quality, land status, and waste management are the main priorities in current management, while tourism policy and product development will be the focus in the future. These findings provide direction for policymakers to design management strategies that are more responsive to changing priorities and evolving dynamics. In conclusion, managing Lake Seran as a sustainable ecotourism destination requires special attention to interacting variables, with a focus on nature conservation and local community empowerment.

Abstract

The use of antibiotics in aquaculture has raised serious concerns regarding the emergence of bacterial resistance and adverse environmental impacts. Red seaweed (Halymenia durvillei) is known to contain bioactive secondary metabolites with potential antibacterial properties. This study aimed to evaluate the antibacterial efficacy of ethanol extract of H. durvillei against four fish pathogenic bacteria, namely Edwardsiella tarda, Aeromonas hydrophila, Aeromonas salmonicida, and Vibrio parahaemolyticus, using agar well diffusion and broth microdilution assays. The experiment was arranged in a completely randomized design consisting of five extract concentrations (100%, 75%, 50%, 25%, and 12.5%) with five replications. The results showed that E. tarda exhibited the largest inhibition zone (16.2 mm) at 100% extract concentration, followed by A. salmonicida (10.8 mm) and A. hydrophila (10.4 mm). In contrast, V. parahaemolyticus did not produce an inhibition zone in the agar diffusion assay. The broth microdilution test revealed minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 25% and 50%, respectively, for all tested bacteria. The red seaweed extract demonstrated both bacteriostatic and bactericidal activity, indicating its potential as a natural antibacterial alternative for disease control in aquaculture.

Abstract

Mangrove ecosystems are widely acknowledged as valuable natural sources of bioactive compounds with potential applications in functional food and pharmaceutical industries. Avicennia marina leaves, in particular, contain diverse secondary metabolites; however, the efficiency of their extraction is strongly influenced by solvent type and polarity. This study aimed to evaluate the effect of different ratios of citric acid–glucose-based natural deep eutectic solvent (NADES) on extraction yield, pH, and phytochemical profile of young A. marina leaf extracts. A Completely Randomized Design (CRD) was applied, consisting of four treatments of citric acid:glucose ratios (1:1, 1:2, 1:3, and 1:4) with four replications. Extraction was performed at 50°C for 60 minutes using a material-to-solvent ratio of 1:20 (w/v). The findings indicated that increasing the proportion of citric acid in the NADES formulation significantly enhanced extraction yield, with the highest yield (20.40%) obtained at the 4:1 ratio. The extract pH ranged from 1.79 to 1.88 and decreased as the citric acid proportion increased. Phytochemical screening confirmed the presence of flavonoids, tannins, and alkaloids, while saponins, steroids, and terpenoids were not detected. Overall, these results demonstrate that citric acid–glucose-based NADES serve as an effective green solvent system for extracting polar bioactive compounds from young A. marina leaves.

Abstract

Mud crab (Scylla serrata) is a group of crustaceans that live in mangrove and estuarine ecosystems. Mud crab have potential with high economic value and have a lot of interest from local and international communities because they have very high nutritional value. In cultivation activities, one of the factors that affect the growth and survival of mud crab is water quality. One of the most important water quality parameters in mud crab cultivation is salinity. Salinity is a water quality parameter that has a limiting factor on the metabolic and physiological conditions of mud crab. This study aims to determine the effect of different salinities on the growth and survival of mud crab (Scylla serrata). The method used in this study is an experimental method with a complete randomized design (CRD) consisting of 5 treatments and 3 replicates, namely P1: 5 g L-1, P2: 10 g L-1, P3: 15 g L-1, P4: 20 g L-1 and K (control): 28 g L-1. The results showed that the best mud crab growth was in the 15 g L-1 salinity treatment, the value obtained in absolute weight growth of 12.33 ± 4.93 g, the specific weight growth rate value of 0.28 ± 0.10%/day with a survival rate of 100%. It can be concluded that different salinity treatments have a significant effect on the growth and survival of mud crab.
