Abstract

Nile tilapia (Oreochromis niloticus) culture faces challenges in achieving optimal production efficiency due to limited land availability and water resources. This study aimed to analyze and compare the productivity and efficiency of the Recirculating Aquaculture System (RAS) and Biofloc systems in Nile tilapia culture. The research employed a comparative experimental approach, measuring growth performance, Food Conversion Ratio (FCR), Survival Rate (SR), and water-quality management efficiency in both systems. The results showed that both systems significantly improved aquaculture productivity compared to conventional methods. The RAS system produced a higher daily growth rate, with productivity reaching 35 to 40 kg/m³ per cycle, survival rates of 85 to 92%, and more stable water quality. Meanwhile, the biofloc system demonstrated better feed efficiency, with an FCR ranging from 0.9 to 1.2, compared to RAS, which ranged from 1.2 to 1.5, and productivity reached 30 to 38 kg/m³ when biofloc was used as an additional nutrient source. Economically, the biofloc system was more efficient in feed and water utilization, whereas RAS was superior in environmental control and in managing high stocking density. These findings provide a scientific basis for aquaculture practitioners in determining the most suitable technology based on business scale, capital capacity, and aquaculture sustainability goals.

Abstract

The research was conducted in December 2025 in the waters of Pangkalan Jambi. The purpose of this research was to analyze the total oil content in sediments, calculate the abundance of benthic diatoms, and explain the relationship between the total oil content in sediment and the abundance of benthic diatoms. The research uses a survey method; three sampling stations with three replications in each station were surveyed. The results showed that the average oil concentration in sediments exceeded the thresholds set by the Department of Water Resources Quality Assurance/Quality Control Program and the Australian and New Zealand Environment and Conservation Council. The results of the calculation of the abundance of benthic diatoms ranged from 2196.14 ind/cm2 to 3362.84 ind/cm2. The highest abundance is around small ports, while the lowest abundance is around the river mouth. Based on simple linear regression, the relationship between sediment oil content and benthic diatom abundance was y = 8281.7 – 1.1367x, with a coefficient of determination (R2)= 0.875 and a correlation coefficient (r) = 0.935. The value of r states a moderate relationship with a constant value b, which is negative, indicating that the higher the oil content, the lower the abundance of benthic diatoms in sediments.

Abstract

Microplastics are plastic particles smaller than 5 mm that are difficult to remove from the ocean. This study aimed to identify the types and levels of microplastics found in vannamei (Litopenaeus vannamei) and white shrimp (Penaeus merguiensis) marketed in Dumai City, conducted from September to November 2025. The method used was a survey, and the research locations were determined using purposive sampling. Vannamei shrimp samples were collected from Bundaran Market, and white shrimp from Dumai City Fish Landing Site (TPI), and analyzed at the Marine Chemistry Sciences of the Department of Marine Sciences, Faculty of Fisheries and Marine Sciences, Universitas Riau. The results of this study indicate that three types of microplastics were present in both shrimp species: fibres, fragments, and films. Statistical analysis further revealed that the microplastic content in both shrimp species across different sizes did not differ significantly (p > 0.05). There were no significant differences in microplastic content between vanamei and white shrimp (p > 0.05). The results of linear regression analysis between microplastic content and shrimp morphometric measurements revealed a weak relationship

Abstract

Trap nets (gombang) are passive fishing gears that utilize tidal currents to capture fish and shrimp in coastal waters. This study aims to identify the composition of catches from trap nets based on tidal conditions in the waters of Insit Village, Meranti Islands Regency. The research method used was a survey method through direct observation and interviews with fishermen. Data analysis was carried out using catch-proportion analysis, including main catch, by-catch, and discards. The results showed that penaeid shrimp and small pelagic fish such as anchovies dominated the catch composition. Catch composition was influenced by tidal conditions, where catches during high tide were higher than during low tide. The catch proportions indicate that trap nets still exhibit low selectivity, as evidenced by the high by-catch rate. Therefore, better management is needed to improve the efficiency and sustainability of trap net fisheries in the area.

Abstract

This study aims to determine the effect of combining blood clam shell (Anadara granosa) filter media on water quality in the recirculation system for Asian Redtail catfish (Hemibagrus nemurus) maintenance. The study was conducted from December 2025 to February 2026 at the Cultivation Technology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau, using a Completely Randomized Design (CRD) experimental method with four treatments and three replications. The treatments consisted of P0 (control without blood clam shell), P1 (150 g/25 L of water), P2 (200 g/25 L of water), and P3 (250 g/25 L of water). The results showed that the use of blood clam shells as a filter medium was able to maintain water quality during cultivation, with a temperature range of 24–28.6°C, pH 2.16–7.94, DO 4.96–6.47 mg/L, TDS 22–1038 mg/L, ammonia 0.015–1.429 mg/L, and nitrate 0.0604–21.2729 mg/L. The best treatment was obtained at P3, with a final fish length of 16.8 cm, SGR of 3.60%, feed efficiency of 93.45%, and the lowest FCR of 1.07. The fish survival rate ranged from 87–96%.

Abstract

This research aims to investigate the impact of barnacle attachment (Balanus sp.) on the operational performance of fishing vessels in Sibolga City, focusing on vessel sailing speed and fuel oil consumption. The research used an experimental method with three hull condition treatments: clean hull, hull with moderate coverage (<50%), and hull with severe patch (>50%). Data collected includes speed, distance traveled, cruise time, and fuel usage. Data analysis involved ANOVA (Analysis of Variance) and simple linear regression. The results showed that barnacle patches significantly influenced ship performance (p=0.000). Ships with clean hulls achieved the highest average speed of 7.82 knots, while ships with severe sticking had the lowest speed. Regression analysis (R2=0.581) confirmed that 58. The level of barnacle attachment caused 1% of the variation in ship speed. Increasing barnacle coverage significantly increases fuel consumption through increasing hydrodynamic drag on the ship's hull. This study concludes that the presence of barnacles substantially reduces the performance and operational efficiency of fishing vessels

Abstract

apiat (Barbonymus schwanefeldii) is one of the economically important freshwater fish found in the Muaro Pijoan River, Jambi. Intensive fishing pressure and water quality degradation due to anthropogenic activities pose threats to the sustainability of this fish population. This study aims to examine the size distribution and growth patterns of kapiat in the Muaro Pijoan River as a scientific basis for development of freshwater aquaculture. Sampling was conducted in October 2025 using traps and gillnets. A total of 83 kapiat were collected, consisting of 51 males and 32 females. Male fish had a total length range of 110–160 mm with a weight range of 20–55 g, while female fish had a total length range of 120–166 mm with a weight range of 21–71 g. The size distribution of male fish was dominated by the 134–141 mm size class (25 individuals), while female fish were dominated by the 156–164 mm size class (13 individuals). Length-weight relationship analysis showed that male fish exhibited a negative allometric growth pattern (b = 2.6399; R² = 0.7313), indicating that length growth was faster than weight gain. In contrast, female fish exhibited a positive allometric growth pattern (b = 3.4445; R² = 0.8998), indicating that weight gain was faster than length growth due to the gonadal maturation process. The relatively smaller size distribution compared to other populations suggests environmental influence on growth performance. These results provide baseline information for domestication strategies, broodstock selection, and feeding management in freshwater aquaculture systems

Abstract

Catfish farming (Clarias gariepinus) is one of the rapidly growing aquaculture sectors in Indonesia. However, the main challenges frequently encountered are limited cultivation land and declining water quality due to the accumulation of metabolic waste, particularly ammonia. The Recirculating Aquaculture System (RAS) offers a solution by reusing culture water, assisted by mechanical, chemical, and biological filtration processes. RAS aims to minimize external water exchange while maintaining water quality at levels suitable for fish survival and growth. This article aims to review the concepts and benefits of recirculating systems in catfish culture, based on a literature review of scientific journals and related books, using a descriptive-exploratory approach. The review indicates that RAS provides numerous benefits, including improved water-use efficiency, enhanced water quality, reduced ammonia concentration, and increased stocking density and productivity in catfish culture. The role of filtration units and microorganisms is crucial in maintaining system stability, particularly in the decomposition of organic waste and toxic compound
