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.

Abstract

This community service activity focused on developing feed production techniques using local raw materials for mud crab farmers in Madak Belek Hamlet, Sekotong District. The main challenge faced by farmers is the high cost of commercial feed, which reduces profit margins. In fact, the area is rich in underutilized nutrient-rich local resources such as trash fish and seafood processing by-products. A participatory approach was applied, including observation, socialization, demonstration, hands-on training, and evaluation. The training emphasized feed formulation and the application of 5% wheat gluten as a binder, which had been proven in preliminary studies to enhance feed stability in water. The results showed an improvement in participants’ knowledge and skills in processing local ingredients into quality feed. The expected impacts include reducing dependence on commercial feed, lowering production costs, and improving the efficiency and sustainability of mud crab farming. For further optimization, feed performance testing on crab growth and economic feasibility analysis are required.

Abstract

Lobster pasir (Panulirus homarus) salah satu komoditas perikanan dengan nilai ekonomi tinggi yang memiliki permintaan besar di pasar lokal maupun internasional. Peningkatan kebutuhan tersebut menjadikan budidaya lobster pasir sebagai peluang usaha yang potensial dan menguntungkan bagi masyarakat pesisir di Dusun Ujung Betok. Dusun Ujung Betok merupakan wilayah pesisir yang memiliki potensi sumber daya laut dan wilayah yang ditetapkan sebagai kawasan budidaya lobster pasir di NTB. Masyarakat nelayannya memiliki sebuah Kelompok Usaha Bersama (KUB) yang bernama Segare Lauq yang bergerak dibidang perikanan dan hasil budidaya laut terutama lobster. Kendala utama yang dihadapi oleh pembudidaya adalah kondisi benih tidak 100% sehat dan siap dibudidayakan. Hampir 50% benih yang didatangkan dari luar atau ditangkap dari alam, dalam satu hingga dua hari pemeliharaan akan mengalami kematian. Permasalahan tersebut dapat diatasi dengan cara penanganan (karantina) benih di dalam sebuah wadah yang disebut wadah karantina sebelum ditebar. Tim pengabdian melakukan sosialisasi dan pendampingan teknis dalam pembuatan wadah karantina dan pemanfaatannya. Wadah karantina didisain berbentuk tabung dengan ketinggian 1,5 m, diameter 1 m dan ukuran mata jaring 1 inch. Melalui penyediaan wadah karantina diharapkan mampu mendukung kegiatan budidaya lobster untuk menghasilkan benih yang lebih sehat, seragam dan siap dibudidayakan. Selain itu wadah karantina berfungsi untuk menampung lobster yang baru dipanen, sehingga dapat memudahkan pembudidaya dalam sortasi dan  mengurangi stress pada lobster yang siap kirim. Kegiatan program pengabdian melalui skema Pengabdian Karya Dosen yang Dimanfaatkan Masyarakat ini juga diharapkan bisa meningkatkan kinerja yaitu pada IKU 5, hasil kerja dosen dapat digunakan dan dimanfaatkan oleh masyarakat.

Abstract

Indonesia is a country that is rich in natural resources and has various potentials that can be developed, especially in the field of aquaculture. Aquaculture activity that is often carried out by Indonesian people is the cultivation of tilapia (Oreochromis niloticus). Apart from that, Indonesia is known as the second largest contributor of plastic waste in the world after China. The scattered plastic waste will be degraded into microplastics which can then spread to tilapia farming locations. The aim of this research is to determine the effect of exposure to polystyrene microplastics given to tilapia feed on their growth. The research method used was a completely randomized design with 4 treatments and 3 replications with doses P1 = 0 mg/0.75 g feed (control), P2 = 0.01 mg/0.75 g feed, P3 = 0.1 mg/ 0.75 g feed, and P4 = 1 mg/0.75 g feed. The parameters tested were absolute weight growth, absolute length growth, spesific growth rate (SGR), feed conversion ratio (FCR) and water quality. The results obtained were that the effect of exposure to polystyrene microplastics in feed was significantly different on absolute weight growth, SGR, and FCR in tilapia (Oreochromis niloticus), but not significantly different on absolute length growth.

Abstract

Plastic is one of the materials most widely used by humans. The more plastic that is used, the more plastic waste is released into environment and will polute water areas in various sizes, both macroplastics and microplastics. Microplastic are classified as plastic particles whose diameter is less than 5 millimeters. One type of microplastic that has an adverse impact on the life of aquatic organisms is polyvinyl chloride (PVC). The aim of this research was to determine the effect of PVC microplastic exposure on the survival rate and growth performance of tilapia, Oreochromis niloticus. This study was conducted in a completely randomized design (CRD) consisting of four treatments with three replications. The treatments were as follows: MP0 = No addition of microplastics (control); MP1 = Addition of 5 mg/L microplastics; MP2 = Addition of 15 mg/L microplastics; MP3 = Addition of 20 mg/L microplastics. The results showed that exposure to polyvinyl chloride microplastics on the survival rate and growth performance of tilapia through water made a real difference to Survival Rate (SR), absolute weight growth, absolute length growth, Specific Growth Rate (SGR), Feed Convension Ratio (FCR) and the abundance of polyvinyl chloride microplastics in fish gut.Keywords:MicroplasticPolyvinyl chlorideTilapiaSurvival rateGrowth performance

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.

Abstract

This study evaluated the effects of waterborne polystyrene microplastic exposure on the growth performance of Siamese fighting fish (Betta splendens) over a 45-day rearing period. A completely randomized design with four treatments and three replicates was applied: 0, 50, 100, and 150 mg/L. The evaluated growth variables comprised absolute length gain, specific length growth rate, absolute weight gain, specific growth rate, feed conversion ratio (FCR), and survival rate (SR). Data were analyzed using one-way ANOVA followed by Tukey’s test at the 5% significance level. Polystyrene microplastic exposure significantly affected absolute length gain, specific length growth rate, absolute weight gain, and specific growth rate (p < 0.05). Fish reared without microplastic exposure consistently showed the highest growth performance, whereas the 150 mg/L treatment produced the lowest values across the principal growth endpoints. By contrast, FCR tended to increase with increasing microplastic concentration, but the effect was not statistically significant (p > 0.05). SR remained 100% in all treatments, indicating that the tested exposure levels produced sublethal rather than lethal effects under the present experimental conditions. Water quality remained within a range generally tolerated by betta fish, suggesting that the observed response was more closely associated with microplastic exposure than with overt deterioration of the rearing medium. Overall, waterborne polystyrene microplastic exposure reduced the growth performance of B. splendens and should be considered a relevant emerging stressor in ornamental fish culture.
