Abstract

One material that can be used to improve feed quality is octopus ink. Octopus ink can serve as an alternative nutrient source to optimize catfish growth. Ink produced by cephalopods such as squid, octopus, and cuttlefish contains various components, including fat, protein, ash, and carbohydrates. The aim of this research is to determine the effect of administering octopus ink extract (Octopus sp.) on the growth of catfish (Clarias sp.) infected with Aeromonas hydrophila bacteria. The method used in this research was experimental, involving five treatments with three replications: treatment 1 (Control/P1), treatment 2/P2 (40 ml/kg), treatment 3/P3 (80 ml/kg), treatment 4/P4 (120 ml/kg), and treatment 5/P5 (160 ml/kg). The research steps included octopus ink extraction, a Lethal Concentration 50 (LC50) test, preparation of tools and materials, supplementation of octopus ink extract in feed, application of test treatments, challenge tests with Aeromonas hydrophila, and maintenance. The results of this research showed that treatment 5 (160 ml/kg) yielded the best outcomes in growth parameters, including an absolute weight of 1.26 grams, a specific growth rate of 0.57%/day, a feed convertion ratio (FCR) of 1.66, and a survival rate of 90%.

Abstract

Vibrio parahaemolyticus is one of the bacteria that can attack whiteleg shrimp and cause Acute Hepatopancreatic Necrosis Disease (AHPND) or Early Mortality Syndrome (EMS) in shrimp. One alternative that can be used is the use of seaweed-based immunostimulants, namely k-carrageenan. The purpose of this study was to evaluate the effectiveness of k-carrageenan mixed in feed with different doses on increasing the immune system of whiteleg shrimp infected with AHPND. This study was conducted for 60 days with an experimental method in the form of a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications, namely, P1 (Positive Control): Commercial Feed + Vibrio parahaemolyticus Infection; P2 (Negative Control): Commercial Feed + 0.9% NaCl Infection; P3: Commercial Feed + Kappa-carrageenan 8 g / kg + Vibrio parahaemolyticus Infection; P4: Commercial Feed + Kappa-carrageenan 10 g/kg + Vibrio parahaemolyticus Infection; P5: Commercial Feed + Kappa-carrageenan 12 g/kg + Vibrio parahaemolyticus Infection. The results of this study indicate that the addition of 12 g/kg of k-carrageenan to the feed affects the survival rate and immune system of whiteleg shrimp infected with Vibrio parahaemolyticus.

Abstract

Optimizing hatchery techniques for guppy (Poecilia reticulata) production is essential for improving reproductive efficiency and economic viability in small-scale ornamental aquaculture. This study evaluated the effectiveness of a simplified spawning system using sterilized aquaria (40×60×40 cm) with aeration and aquatic vegetation to create a semi-natural environment. Broodstock selection based on gonadal maturity and a male-to-female ratio of 2:4 resulted in high spawning success, with courtship behavior observed by day three. A staged feeding strategy—infusoria and egg yolk (days 1–3), Artemia nauplii (days 4–10), and Tubifex (days 11–21)—supported consistent larval growth from 0.5 cm to 1.6 cm over three weeks. Larval survival reached 91.1%, with 162 of 168 fry surviving by day 21. Stable water quality parameters (24–26°C, 7.6–7.9 mg/L dissolved oxygen, pH 6.7–7.1) were maintained through regular siphoning and water renewal. Economic analysis indicated system feasibility, with a production cost of IDR 1,369,250, revenue of IDR 1,620,000, and net profit of IDR 250,750. The benefit-cost ratio (R/C) was 1.18, the break-even point was achieved at 136.93 fry, and the payback period was 17.7 months. These findings highlight the biological and financial viability of low-cost guppy hatchery systems suitable for rural aquaculture settings. Future research should focus on scaling potential, feed alternatives, and digital monitoring to improve system sustainability and profitability.

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

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.
