Abstract

The probiotic innovation training programme based on market waste implemented at the Krido Yuwono Mina Padi Technopark Group aims to increase tilapia productivity and farming efficiency through the use of organic waste as raw material for probiotics. This training involves participants in the production of probiotics through the fermentation of market waste using lactic acid bacteria starters. The evaluation results show an increase in tilapia productivity of around 15-20% with better feed efficiency and a reduction in ammonia levels in pond water, which was previously a major problem in maintaining fish health. The community involved in this programme also increased their confidence in managing tilapia farming efficiently and received new knowledge that can reduce operational costs. This programme has achieved significant social and economic impacts and is expected to develop into a sustainable community empowerment model in the field of aquaculture and support more environmentally friendly waste management.

Abstract

Lactococcus lactis strain UIS6 is a lactic acid bacteria isolate that has been successfully isolated and developed as a probiotic isolate. Carbon sources are very important factors in supporting the growth of probiotic isolates both in culture media and production media. This study aimed to determine the type and concentration of carbon sources suitable for optimizing the growth of L. lactis strain UIS6. This study was conducted in two stages, 1). Determination of the type of carbon source and 2). Determination of the dose as a continuation of the first stage of the study. Experimental designs are used to test the specified treatments. A total of 4 types of carbon sources in this study include rice bran, soybean meal, fish meal, and molasses. The results of the study showed that soybean meal had an effect on the growth of L. lactis strain UIS6 (p <0.05). Furthermore, the concentration of soybean meal carbon sources was tested at several concentrations, namely 5%, 10%, 15%, and 20% of the total volume of the treatment media. A concentration of 20% was able to optimally increase the growth of L. lactis strain UIS6, obtaining a density of 6.1 x 108 cells/ml-1 after 24 hours. Soybean meal flour has great potential to be developed as a carbon source for probiotic products.

Abstract

Larva merupakan fase kritis dalam budidaya ikan karena sistem pencernaannya belum sempurna dan sensitif terhadap lingkungan, terutama ketersediaan pakan. Salah satu jenis pakan larva ikan yaitu pakan alami rotifera (Brachionus plicatilis), yang umumnya dikultur dengan mikroalga, salah satunya Nannochloropsis oculata atau dengan suplementasi untuk pengkayaan. Selain itu, rotifera juga dapat diberi pakan dengan bahan alternatif seperti ragi roti (Saccharomyces cerevisiae). Namun, ragi roti harus diberikan dengan dosis yang tepat karena pemberian yang berlebihan dapat mengganggu pertumbuhan rotifera. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ragi roti dengan dosis berbeda terhadap kepadatan dan laju pertumbuhan populasi rotifera. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan (A: Nannochloropsis oculata 10 mL/L/hari (kontrol), B: N. oculata 10 mL/L + S. cerevisiae 10 mL/L/hari, C: N. oculata 10 mL/L + S. cerevisiae 20 mL/L/hari, D: N. oculata 10 mL/L + S. cerevisiae 30 mL/L/hari) dalam skala 2 L. Bahan perlakuan menggunakan larutan stok N. oculata kepadatan 10⁴ sel/mL dan pengenceran ragi roti dengan dosis 8 gram/ L. Pemeliharaan dilakukan selama 8 hari dengan tahapan persiapan alat dan bahan, sterilisasi, kultur, pengamatan kepadatan, pemanenan, dan analisis data. Data kepadatan dan laju pertumbuhan populasi rotifera dianalisis menggunakan uji Kruskal Wallis dan Mann Whitney. Hasil penelitian menunjukkan bahwa pemberian ragi roti dengan dosis berbeda berpengaruh nyata (p<0,05) terhadap kepadatan dan laju pertumbuhan populasi rotifera. Perlakuan terbaik yaitu pada perlakuan D yang menghasilkan kepadatan 118 individu/mL dan laju pertumbuhan 0,411 individu/mL/hari dengan waktu penggandaan diri selama 37,1 jam.

Abstract

Daphnia, a genus of planktonic crustaceans, has gained significant attention in aquaculture due to its high nutritional value and suitability as live feed for fish larvae. This review synthesizes current research on Daphnia production, nutritional variability, and its role in enhancing fish larvae development. Numerous research findings indicate that the protein content of Daphnia provided to different fish larvae ranges from 40% to 60%. We explore the advancements in culture techniques, including the use of organic manures, microalgae, and probiotics, to optimize Daphnia yield and nutritional quality. The review highlights the benefits of Daphnia in improving fish larvae growth, survival rates, and immune response, while also addressing its role in nutrient recycling and water quality management. However, large-scale production faces challenges such as environmental sensitivity, limited shelf life, and competition with other live feeds. Sustainable practices, including the use of closed recirculating systems and bioencapsulation, are essential to mitigate ecological impacts and ensure long-term viability. By integrating current knowledge and identifying research gaps, this review underscores the potential of Daphnia as a sustainable and effective live feed in aquaculture, while calling for further innovation to overcome existing challenges.

Abstract

The high cost and limited availability of fishmeal in aquaculture feed formulations have prompted the search for sustainable and affordable alternative protein sources. This study aimed to evaluate the effects of substituting fishmeal with silk worm (Tubifex sp.) meal on the growth performance, feed utilization, and survival rate of Nile tilapia (Oreochromis niloticus) fry. A completely randomized design (CRD) was used with four dietary treatments: P1 (control, 0% Tubifex), P2 (15%), P3 (25%), and P4 (35%), each with three replications. Fish were fed twice daily for 30 days, and growth parameters were measured weekly. Results showed that the inclusion of Tubifex meal significantly improved the final weight, specific growth rate (SGR), average daily gain (ADG), and feed efficiency (FE), particularly in P3 and P4. The highest SGR (2.28%/day), ADG (0.016 g/day), and FE (61.93%) were recorded in the P4 group. Survival rate also improved, reaching 82.22% in P4 compared to 51.11% in the control. Water quality parameters remained within optimal ranges, indicating no adverse environmental impact from Tubifex inclusion. The findings suggest that Tubifex meal is a viable protein source that can replace fishmeal by up to 35% in tilapia fry diets. Its application offers nutritional, economic, and ecological benefits, making it a promising component in sustainable aquafeed development.
