Abstract

Pacific white shrimp (Penaeus vannamei) is one of Indonesia's fishery commodities with high economic value in the domestic and foreign markets. They are applying appropriate technology through small-scale shrimp farming aimed to transfer technology in partner villages from traditional to intensive systems. This program was an effort to improve the welfare of the fishery community in Desa Pengambengan, Jembrana, Bali. This program was carried out in May‒July 2022, and it involved the Mina Jaya Fish Cultivator Group as the target community. The activity program was carried out through several stages, including audience activity, counseling, technical assistance, and monitoring and evaluation. The activity succeeded in increasing the knowledge and skills of the target community regarding vaname shrimp cultivation in detail. Technical assistance for cultivation activities has increased community understanding of small-scale intensive shrimp cultivation, minimizing errors and increasing program success. Monitoring and evaluation are carried out to determine the sustainability of activities in the target community. This community service activity has succeeded in increasing the productivity of Pacific white shrimp cultivation and technology transfer from the traditional system to a small-scale intensive system.

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

Phytoplankton dynamics, especially Cyanophyta abundance, play a crucial role in shaping water quality and overall productivity in intensive whiteleg shrimp (Litopenaeus vannamei) culture. However, the interactions between key water quality parameters and Cyanophyta proliferation remain poorly understood under commercial farming conditions. This study aimed to examine the relationships between ammonium, nitrite, nitrate, phosphate, total organic matter (TOM), dissolved oxygen (DO), and Cyanophyta abundance in two intensive shrimp ponds with contrasting phytoplankton conditions. This study compared two ponds operated by PT Pyramide Paramount Indonesia that differed in stocking density, pond size, and culture conditions. Weekly measurements included Cyanophyta abundance and composition using microscopy and a Neubauer counting chamber, as well as monitoring water quality parameters daily and weekly through in-situ and ex-situ methods. Pearson’s correlation was used to assess the relationships between the variables. The High Cyanophyte (HC) pond exhibited significantly higher cell abundance (47,400 cells mL⁻¹) and dominance compared to the Low Cyanophyte (LC) pond (18,250 cells mL⁻¹). Multiple regression confirmed that dissolved oxygen was the only significant predictor of Cyanophyta abundance, explaining 51.9% of the variance, whereas nutrients and total organic matter were not significant predictors. Shrimp in the LC pond showed better growth performance, with higher final biomass (6,110.33 kg), lower FCR (1.26), and greater productivity (17.65 ton ha-1), indicating that lower Cyanophyta levels may promote more stable culture conditions than higher ones. These findings highlight the need to manage phytoplankton dynamics and DO availability to enhance water quality and promote sustainable shrimp farming. Dinamika fitoplankton, khususnya kelimpahan Cyanophyta, berperan penting dalam membentuk kualitas air dan produktivitas secara keseluruhan pada budidaya intensif udang vaname (Litopenaeus vannamei). Namun, interaksi antara parameter kualitas air utama dan proliferasi Cyanophyta masih kurang dipahami dalam kondisi budidaya komersial. Penelitian ini bertujuan untuk mengkaji hubungan antara amonium, nitrit, nitrat, fosfat, total bahan organik (TOM), oksigen terlarut (DO), dan kelimpahan Cyanophyta di dua tambak udang intensif dengan kondisi fitoplankton yang kontras. Penelitian ini membandingkan dua tambak yang dioperasikan oleh PT Pyramide Paramount Indonesia, namun berbeda dalam kepadatan tebar, ukuran tambak, dan kondisi budidaya. Pengukuran mingguan meliputi kelimpahan dan komposisi Cyanophyta menggunakan mikroskop dan counting chamber Neubauer, sementara parameter kualitas air dipantau secara harian dan mingguan melalui metode in-situ dan ex-situ. Korelasi Pearson digunakan untuk menilai hubungan antarvariabel. Tambak dengan kelimpahan Cyanophyta tinggi (HC) menunjukkan kelimpahan sel yang jauh lebih tinggi (47.400 sel mL⁻¹) dan dominansi dibandingkan dengan kolam kelimpahan Cyanophyta rendah (LC) (18.250 sel mL⁻¹). Analisis regresi berganda mengonfirmasi oksigen terlarut sebagai satu-satunya prediktor signifikan bagi kelimpahan Cyanophyta, yang menjelaskan 51.9% varians, sementara nutrien dan total bahan organik bukan merupakan prediktor yang signifikan. Udang di tambak LC menunjukkan kinerja pertumbuhan yang lebih baik, dengan biomassa akhir lebih tinggi (6,110.33 kg), FCR lebih rendah (1.26), dan produktivitas lebih besar (17.65 ton ha⁻¹), yang mengindikasikan bahwa tingkat Cyanophyta yang lebih rendah dapat mendukung kondisi budidaya yang lebih stabil. Temuan ini menekankan pentingnya pengelolaan dinamika fitoplankton dan ketersediaan oksigen terlarut untuk meningkatkan kualitas air dan produksi udang yang berkelanjutan.

Abstract

The lemuru (Sardinella lemuru) fishery at Pengambengan Nusantara Fishing Port (NFP) is vital to the local economy but faces challenges from fluctuating catches, potentially linked to overexploitation. This study evaluates the sustainability status of this fishery using the Ecosystem Approach to Fisheries Management (EAFM) framework. Research conducted from May 2024 to July 2024 employed a mixed-methods approach, including direct observation, surveys, and interviews with 110 fishers, alongside biological data from 2,653 fish specimens. A multi-criteria analysis was used to calculate a composite sustainability index. The overall assessment yielded a score of 73,33 ('good' status), indicating that fisheries management at PNFP is generally satisfactory. However, critical issues were identified: a declining trend in fish size and inadequate management of Endangered, Threatened, and Protected (ETP) species. The study concludes that while the fishery is currently well-managed, urgent interventions are needed. Key recommendations include enforcing regulations on minimum catchable size and net mesh selectivity, alongside strengthening monitoring, control, and surveillance (MCS) to combat illegal, unreported, and unregulated (IUU) fishing and ensure long-term sustainability.
