Abstract

Water quality is a key factor in the cultivation of snakehead fish (Channa striata) because it can influence the level of physiological stress that impacts the health and growth of the fish. Three cultivation systems commonly used to manage water quality sustainably are the green water system, biofloc, and aquaponics. All three have different approaches to recycling waste and maintaining the balance of the cultivation environment. This study aims to compare the effectiveness of the three systems in maintaining water quality and reducing physiological stress in snakehead fish. The method used was a Completely Randomized Design (CRD) with three treatments and three replications. The parameters observed included levels of ammonia, nitrite, nitrate, dissolved oxygen (DO), and blood glucose levels as an indicator of stress. The results showed that the biofloc system produced the lowest blood glucose level (54 mg/dL), as well as the lowest nitrite and nitrate concentrations compared to the other treatments. Meanwhile, the biofloc system green water produces ammonia and dissolved oxygen (DO) levels, but biofloc is the most stable in maintaining water quality and the health of snakehead fish.

Abstract

The purse seine fishery in Sibolga plays a vital role in fish production but faces challenges regarding compliance with licensed fishing ground regulations. Non-compliance, driven by economic pressure and declining fish stocks, threatens resource sustainability and fishermen’s welfare. This study aimed to analyze fishermen’s perceptions and compliance levels regarding the use of licensed fishing areas and their relationship to regulatory enforcement. The research was conducted from January-March 2024 at Sibolga Archipelago Fishing Port, North Sumatra, one of the main landing bases for purse seine vessels. Data were collected from 115 respondents, consisting of vessel captains and mates, using structured questionnaires and direct interviews. Observations and secondary data from fisheries institutions supported the primary data. Data were analyzed using descriptive statistics and the non-parametric Kruskal–Wallis test to determine differences in perceptions and compliance among fishing groups categorized by vessel tonnage and fishing zones. The results showed that fishermen’s perceptions of potential fishing grounds and fish resource availability were relatively uniform across groups, indicating a shared view that fishing effort continues to expand to secure catches. In contrast, perceptions of VMS usage differed significantly, with the 30–100 GT small pelagic purse seine group acknowledging its role in detecting violations. Compliance levels also varied, with the 30–100 GT small pelagic purse seine operating in <12-mile zones showing the lowest compliance. It is concluded that stricter enforcement, effective monitoring, and targeted empowerment programs are necessary to enhance compliance and ensure sustainable fisheries management in Sibolga.

Abstract

The cultivation of African catfish (Clarias gariepinus) using a biofloc system is an aquaculture technology that integrates waste management and the production of natural feed in situ, thereby enhancing productivity efficiently. This research aimed to evaluate the effect of EM4 probiotic application in a biofloc system on the growth and survival rate of catfish under different stocking densities. The experiment was conducted using a Completely Randomized Design (CRD) with four stocking density treatments: P1 (30 fish/30 L), P2 (40 fish/30 L), P3 (50 fish/30 L), and P4 (60 fish/30 L), each with three replications. Observed parameters included absolute weight and length growth, floc content, hematocrit, hemoglobin, erythrocytes, leukocytes, differential leukocytes and water quality parameters. The treatment P4 showed the most notable effects, with a final absolute weight gain of 11.66 grams and an absolute length increase of 8.11 cm. Furthermore, the probiotic addition had a significant impact on erythrocyte levels and differential leukocyte counts. In contrast, the use of probiotics in the biofloc system did not result in significant differences in hematocrit levels, total leukocyte counts, or biofloc volume.

Abstract

Aquatic animals play a significant role in bioremediation processes in aquatic environments through their natural activities, such as filtering particles, aerating water, and nutrient cycling. This study aims to review the use of aquatic animals as natural biofilters in aquaculture systems, highlighting their efficiency and the supporting role of microbial technology. The method used is a literature review from 24 relevant articles published between 2015 and 2024. Results show that species such as goldfish, catfish, and eels can reduce organic waste, regulate plankton composition, and enhance oxygen levels. Moreover, the integration of probiotics and biotechnologies such as microbial fuel cells, bioaugmentation, and biostimulation improves pollutant degradation and water quality. The implications of these findings suggest that aquatic animal-based bioremediation is a promising and environmentally friendly approach to sustainable aquaculture, reducing reliance on antibiotics and chemical disinfectants while supporting ecological balance and animal health.

Abstract

The waters of Lambur Luar Village are a productive coastal area that supports capture fisheries activities, one of which is through the use of bottom gillnets. This fishing gear is considered fairly selective and environmentally friendly, making it important to assess its effectiveness in terms of catch composition. This study aims to analyze the main catch, bycatch, and discard from bottom gillnets operated by local fishers. The method used was a survey with purposive sampling on ten fishing units, with four replications per unit. The data were analyzed descriptively and supported by biodiversity indices, including diversity, evenness, and dominance. The results showed that mantis shrimp (Harpiosquilla raphidea) was the dominant main catch, with the highest number and biomass. Bycatch was dominated by demersal fish such as croaker (Johnius trachycephalus), tongue sole (Cynoglossus lingua), Chacunda gizzard shad (Anodontostoma chacunda), fourfinger threadfin (Eleutheronema tetradactylum), along with several other species. Meanwhile, discards consist of non-economic benthic organisms such as snails, starfish (Asteroidea spp.), horseshoe crabs (Tachypleus gigas), and ghost crabs (Ocypoda quadrata). The diversity index indicated a moderate category, reflecting ecosystem balance, while the dominance index was low, suggesting no single species excessively dominated the ecosystem. In conclusion, bottom gillnets with a mesh size of 3.5 inches proved effective in capturing target organisms suitable for consumption while reducing the proportion of unwanted discards. This indicates that bottom gillnets have the potential to support sustainable fisheries practices without causing significant negative impacts on the benthic ecosystem in the waters of Lambur Luar Village.

Abstract

The rapidly increasing demand for silkworms as natural feed has caused prices to rise, making silkworms a potentially valuable natural feed for farmed fish. To date, the supply of silkworms as natural feed still relies on nature, meaning that silkworms are not available throughout the year, but only during the rainy season. One way to support the availability of silkworms is through cultivation. The purpose of this study was to examine the effect of chicken manure, rice field mud, and tofu pulp on the growth of silkworms. The method used was a quantitative experiment with a completely randomized design (CRD) consisting of four treatments: P1 (100% mud), P2 (50% mud + 50% chicken manure), P3 (50% mud + 50% tofu pulp), and P4 (50% mud + 25% chicken manure + 25% tofu pulp). The results of the study showed that treatment P4 provided the highest absolute biomass growth with an average of 3.03 g. This indicates that the combination of chicken manure and tofu pulp provides an optimal synergistic effect for worm growth. From these results, it can be concluded that the combination of rice field mud, chicken manure, and tofu pulp (P4) is the most effective medium for silkworm growth.

Abstract

Climate change poses a significant threat to the sustainability of global aquaculture, including biofloc-based aquaculture systems (BFT). While BFT improves nutrient use efficiency and reduces water consumption, energy efficiency remains a key challenge, especially in terms of energy intensity and oxygen transfer (OTE/SOTE). This study conducts a systematic literature review (SLR) using the PRISMA 2020 method, focusing on energy efficiency in tilapia cultivation with BFT and adaptation strategies to climate variability. Key findings emphasize the importance of aeration, design optimization, and C/N management in minimizing energy consumption without compromising production. Additionally, integrating technologies like IoT/AI for adaptive DO control shows great potential in reducing energy intensity. This research contributes a systematic framework that links energy metrics with aeration design and operational adaptation strategies, offering guidance for developing more efficient and climate-resilient BFT systems. The study also recommends implementing renewable energy and smart water quality monitoring technologies to enhance aquaculture sustainability.

Abstract

Nile tilapia (Oreochromis niloticus) is one of the most important aquaculture species worldwide, but intensive farming has increased susceptibility to bacterial infections, particularly Aeromonas hydrophila, which threatens productivity and survival. This study evaluated fermented papaya (Carica papaya L.) leaf extract (FPLE) as a natural immunostimulant and sustainable alternative to antibiotics in Nile tilapia culture. A 45-day feeding trial was conducted using a completely randomized design with five treatments (0, 16, 18, and 20 mL FPLE/kg feed) and three replicates. Hematological, immunological, growth, and bacterial resistance parameters were analyzed. Results showed that supplementation with 20 mL/kg FPLE significantly increased post-infection leukocyte counts (2.82×10⁴ vs. 2.40×10⁴ cells/mm³), phagocytic activity (46.26% vs. 39.51%), and erythrocyte levels (5.85×10⁶ vs. 5.25×10⁶ cells/mm³). Differential leukocyte analysis revealed lymphocyte dominance (90.33%) and elevated monocytes (13.33%), indicating enhanced adaptive and nonspecific immunity. In addition, total bacterial load decreased by 22.4%, and specific growth rate improved (4.34% vs. 4.22%/day), while water quality remained within optimal ranges. The synergistic effects of papaya-derived bioactive compounds and Lactobacillus casei probiotics from Yakult likely contributed to immune enhancement and nutrient absorption. FPLE supplementation at 20 mL/kg optimized immunostimulation without compromising survival (77–84%), demonstrating its dual role in disease prevention and growth promotion. These findings highlight FPLE as a safe, eco-friendly feed additive with strong potential for reducing antibiotic dependence and supporting sustainable tilapia aquaculture.

Abstract

The Pacific white shrimp (Litopenaeus vannamei) is one of the most important species in global aquaculture but remains highly vulnerable to bacterial, viral, and environmental stressors. Conventional reliance on antibiotics and chemicals has raised concerns over resistance and sustainability, underscoring the need for eco-friendly alternatives. Alginate, a natural polysaccharide extracted from brown seaweeds such as Sargassum, has emerged as a promising immunostimulant and functional feed additive. Experimental studies show that alginate supplementation enhances non-specific immune responses, including total haemocyte count, phenoloxidase, superoxide dismutase, phagocytic activity, and total plasma protein. At the molecular level, alginate upregulates immune-related genes (e.g., Toll, LGBP, proPO), resulting in higher resistance against Vibrio spp. and White Spot Syndrome Virus (WSSV). In addition, low molecular weight sodium alginate improves antioxidant activity and stress tolerance under cadmium exposure, while dietary supplementation supports growth performance and feed utilization. From a sustainability perspective, converting Sargassum biomass into alginate aligns with circular economy principles by transforming an abundant, underutilized seaweed into high-value aquafeed additives. This reduces dependency on antibiotics and synthetic chemicals while generating added value for coastal communities. Overall, alginate represents a multifunctional and cost-effective strategy to strengthen shrimp immunity, enhance resilience to pathogens and stressors, and promote environmentally responsible aquaculture production.
