Abstract

Whiteleg shrimp (Litopenaeus vannamei) dominates global aquaculture production due to its adaptability to intensive systems. However, intensive systems often experience excess accumulation of nitrogenous waste and total organic matter (TOM), which can destabilize microbial communities and affect water quality. While protozoa are known as bioindicators, few studies have explored how their functional composition interacts with nitrogen cycling and production performance in shrimp ponds. This study investigated the relationships between nitrogenous compounds, TOM, bacterial and protozoan abundance in two intensive shrimp ponds (HP: high protozoan abundance and LP: low protozoan abundance). Water quality parameters, including Total Ammonia Nitrogen (TAN), nitrite, nitrate, TOM, and phosphate, were monitored weekly alongside microbial assessments of total bacterial count (TBC), total Vibrio count (TVC), and protozoa abundance. Protozoa were identified microscopically, while shrimp performance was measured by growth, feed conversion ratio (FCR), survival, and productivity. TOM emerged as the primary ecological driver, significantly correlating with Vibrio abundance (r = 0.585, p < 0.05). Although the high-protozoa pond featured greater bacterial biomass and more bacterivorous taxa (e.g., Ciliata, Vorticella), it had lower shrimp productivity. Conversely, the low-protozoa pond dominated by detritivores (Euplotes, Strombidionopsis) achieved superior growth, FCR, and final biomass, despite higher TOM and nitrite levels. These findings suggest that protozoan functional composition, rather than total abundance, critically influences nutrient cycling, microbial stability, and production outcomes. Managing TOM and fostering beneficial microbial loops are essential strategies for sustainable shrimp farming.

Abstract

Abstrak: Pelatihan penulisan karya ilmiah multidisiplin dan komersialisasi hasil penelitian dengan dukungan AI bertujuan untuk meningkatkan kemampuan peserta dalam menghasilkan karya ilmiah berkualitas dan memanfaatkan hasil penelitian secara ekonomis. Kegiatan ini dirancang dengan pendekatan praktis, mengintegrasikan teknik penulisan karya ilmiah, strategi komersialisasi hasil penelitian, dan penggunaan teknologi kecerdasan buatan (AI). Pelatihan meliputi sesi teori, praktik langsung, serta diskusi interaktif yang melibatkan peserta dari berbagai disiplin ilmu. Kegiatan diikuti 292 peserta dengan berbagai profesi dan narasumber yang berasal dari BRIN, Universitas Padjadjaran, dan INSTIKI. Evaluasi keberhasilan kegiatan dilakukan melalui survei kepuasan peserta, dengan hasil menunjukkan nilai rata-rata sebesar 3,75 dari skala 4. Hal ini mencerminkan tingkat kepuasan yang sangat tinggi terhadap pelaksanaan, relevansi, dan manfaat pelatihan. Peserta merasa terbantu dalam memahami cara memanfaatkan AI untuk menyederhanakan proses penulisan dan merancang strategi komersialisasi hasil penelitian mereka. Hasil kegiatan ini diharapkan dapat mendukung peningkatan kualitas karya ilmiah nasional serta mendorong inovasi penelitian berbasis teknologi untuk memberikan dampak nyata bagi masyarakat.Abstract: Multidisciplinary scientific writing and research result commercialization training with AI support aims to improve participants' ability to produce quality scientific work and utilize research results economically. This activity is designed with a practical approach, integrating scientific writing techniques, research result commercialization strategies, and the use of artificial intelligence (AI) technology. The training includes theory sessions, hands-on practice, and interactive discussions involving participants from various disciplines. The activity was attended by 292 participants with various professions and speakers from BRIN, Padjadjaran University, and INSTIKI. Evaluation of the success of the activity was carried out through a participant satisfaction survey, with the results showing an average value of 3.75 on a scale of 4. This reflects a very high level of satisfaction with the implementation, relevance, and benefits of the training. Participants felt helped in understanding how to utilize AI to direct the writing process and design strategies for commercializing their research results. The results of this activity are expected to support improving the quality of national scientific work and encourage technology-based research innovation to provide real impacts on society.

Abstract

Goonch (Bagarius yarelli) is one of the local fish species affected by dynamic changes due to activities along Perjaya Dam. The first component in conducting the cultivation of local fish is domestication The main problem in domestication is the adaptation of wild fish to the controlled environment. Another aspect that needs to concern in domestication is the defense of domesticated species from several pathogens, especially parasites because most of wild fish captured from natural habitats are attacked by several parasites. This study aimed to determine the prevalence and intensity of ectoparasites attacked goonch captured from Perjaya Dam. The sampling method used was purposive sampling method and followed by laboratory examination. A total number of 90 goonch were collected using fishing rods and gillnets with an aid from local fishermen during this study. Ectoparasites were examined on several external organs including skin or scales, fins, and gills. Ectoparasites found during the sample examination were recorded for further calculation of ectoparasites types, prevalence, and intensity. The measurement of water quality parameters was performed after sample collection. Water quality parameters measured consisted of temperature, pH, dissolved oxygen, ammonia, and transparency. Goonch captured from Perjaya Dam were infested by Lernaea sp. and Gyrodactylus sp. through single infestation and with the same prevalence level (1.11%). Lernaea sp. showed a higher intensity (52 ind/fish) on goonch than that of Gyrodactylus sp. (1 ind/fish). Almost all water quality parameter in sampling site, including temperature, pH, and dissolved oxygen, were in normal ranges to support the live of freshwater fish.Keywords:EctoparasitesGoonchGyrodactylus sp.Lernaea sp.Prevalence
