GROWTH PERFORMANCE AND SURVIVAL RATE OF SAND LOBSTER (Panulirus homarus sp.) IN AN INDOOR SYSTEM
Full text linkSand lobster (Panulirus homarus sp.) is one of the promising fishery commodities with high economic value and is considered a leading export species in Indonesia's fisheries sector. The cultivation of sand lobster using floating net cages (KJA) in the sea still faces many challenges. Therefore, innovative cultivation technologies for lobsters are urgently needed. This study aims to assess the growth performance and survival rate of sand lobsters cultivated in a closed system (indoor system). The research was conducted using four fiberglass tanks measuring 4 x 2 x 1 m (water height 0.5 m). The average initial body weight (IBW) of the lobster seed used was 79.8 ± 5.8 (mean ± SE) with a stocking density of 10 individuals/m². The feed provided consisted of trash fish and golden apple snails, with a feeding rate of 15% of the total biomass. Growth sampling was conducted every three weeks. Sand lobsters cultivated for nine weeks (63 days) had an average final body weight (FBW) of 91.1 ± 5.2 grams/individual. The weight gain (WG) and specific growth rate (SGR) of the sand lobsters during the study were 14.2 ± 1.5% and 0.22 ± 0.02%, respectively. The feed conversion ratio (FCR) during the study was 10.1 ± 0.1, while the average daily growth (ADG) was 0.19 ± 0.01 grams/day. The survival rate (SR) of the sand lobsters decreased over the maintenance period, reaching 75.6 ± 2.8% by the end of the study.
THE GROWTH PERFORMANCE OF WHITE SNAPPER (Lates calcarifer) FINGERLINGS IN ODE AQUACULTURE AND AGRICULTURE HATCHERY UNIT, BRUNEI-MUARA BRUNEI DARUSSALAM DISTRICT
Full text linkWhite snapper (Lates calcarifer) is a high value aquaculture commodity with increasing market demand. This study aimed to analyzed the growth performance of white snapper fry during the nursery phase at the ODE Aquaculture and Agriculture Hatchery Unit, Brunei-Muara District, Brunei Darussalam, from March to June 2023.The nursery utilized controlled fiberglass tanks equipped with aeration and a flow-through water system. Two types of tanks were used: rectangular tanks measuring 4 × 1.5 × 1 m (capacity: 6,000 L) and circular tanks with a diameter of 2 m (capacity: 3,140 L). A total of 100,000 fry were stocked, with 30,000–40,000 fry per tank. Observed parameters included survival rate (SR), absolute length growth rate, absolute weight growth rate, specific growth rate (SGR), and feed conversion ratio (FCR). Water quality parameters measured were temperature, salinity, and pH. Results indicated an absolute length growth rate of 1.2 cm/week, surpassing previous studies reporting only 0.4 cm/week. The absolute weight growth rate was 1.3 g/week, exceeding the 0.6–1 g/week range reported in other research. The FCR was 0.33, demonstrating excellent feed efficiency. However, the survival rate was 30.77%, below the standard for controlled nursery systems (>50%), likely due to high stocking density and cannibalism. Harvest size ranged from 8 to 9 cm. Water quality remained stable, with temperatures between 31–32.5°C, pH levels from 7.6–8.3, and salinity ranging from 30–32 ppt. Despite the low survival rate attributed to high stocking density, the nursery phase at this facility achieved commendable growth rates compared to previous studies. This success is supported by stable water quality and the provision of high-protein feed

Strengthening Indonesia’s Maritime Safety Governance: Insights From Ship Accident Trends and Regulatory Oversight
Full text linkThe high rate of ship accidents highlights a persistent gap between safety regulations, supervision, and field implementation, making maritime accidents a continuing challenge for Indonesia’s shipping safety system. This study examines the key components influencing maritime safety governance and identifies strategic priorities for strengthening regulation and oversight. Using the SWOT–AHP (Strengths, Weaknesses, Opportunities, and Threats–Analytic Hierarchy Process) method, internal and external factors were assessed through pairwise comparisons to establish consistent priorities. The findings indicate that international and national regulations (31.1%), maritime education and training (14.8%), and Port State Control (PSC) supervisory capacity (13.6%) are the most critical factors, while structural weaknesses such as low inspection frequency (7.2%) and the lack of safety culture (3.7%) remain major barriers. Opportunities in digital monitoring (2.6%) and threats from extreme weather (2.5%) underscore the need for adaptive, risk-based strategies. The novelty of this study lies in integrating the SWOT–AHP framework with Risk-Based Management (RBM) and strategic management theory to produce a measurable strategic priority map that directly links quantitative evidence to policy planning, implementation, and evaluation. Furthermore, the study introduces a time-phased, multi-actor policy strategy comprising short-term (1–3 years) initiatives, such as regulatory harmonization, digital monitoring, and capacity building led by the Ministry of Transportation and long-term (4–10 years) reforms emphasizing institutional integration, AI-based predictive safety systems, and national safety culture development led by cross-ministerial coordination. This combined approach provides a practical and data-driven foundation for achieving adaptive, measurable, and sustainable maritime safety governance in Indonesia

Full text linkThis study aimed to evaluate the potential infection of bacteria Vibrio spp. and parasites in farmed barramundi (Lates calcarifer) and wild fish inhabiting Inner Ambon Bay. The research was conducted over a five-month period (August–December 2024) using a purposive sampling, to monthly collect and analyse two barramundi populations. Bacteria were isolated from liver and kidney tissues of the collected fish using sea water complate (SWC) agar and tiosulfate citrate bile-salt sucrose (TCBS) agar and identified with the Analytical Profile Index (API) 20 Non-Enteric (NE) kit. Parasitic identification was performed microscopically on gills, skin, and intestinal samples. The results revealed that Vibrio spp. were detected at relatively high abundance, dominated by V. harveyi, V. alginolyticus, and V. vulnificus. Identified parasites included Trichodina sp., Cryptocaryon irritans, Benedenia sp., and nematodes. Parasite infection prevalence in cultured barramundi ranged from 40% to 70%, whereas in wild fish it reached 60%. These findings strongly indicate the potential for cross-transmission of diseases between cultured and wild fish populations in Inner Ambon Bay.Penelitian ini bertujuan mengevaluasi potensi infeksi bakteri Vibrio spp. dan parasit pada ikan kakap putih (Lates calcarifer) budidaya dan ikan liar di perairan Teluk Ambon Dalam.
