The majority of the population of Bogak Village works as fishermen, with 76% of them involved in fishing. The dominant fishing gear used is gill nets, with a total of 500 units. This study was conducted in Bogak Village in 2023 to determine the investment spent by fishermen, the total costs, income, and profits they obtain, and to analyze the feasibility of fishing efforts using gill nets. This research method is a survey method with 21 fishermen as respondents. The results indicate two criteria for the type of fishing business: using 5 GT and 10 GT fleets. The investment for a 5 GT fleet is IDR 78,991,375.00, while a 10 GT fleet costs IDR 232,150,972.22. The total cost of the 5 GT fleet is IDR 525,031,138.89 / year, and the 10 GT fleet is IDR 776,833,809.52 / year. The income of the 5 GT fleet is IDR 581,760,000.00/year, and the 10 GT fleet is IDR 904,106,666.67/year. The profit of the 5 GT fleet is IDR56,728,861.11/year, and the 10 GT fleet is IDR127,272,857.14/year. Based on the feasibility analysis of the gillnet fishing business, both fleet sizes (5 GT and 10 GT) have proven to be profitable with an R/C value above 1. This indicates that the company is feasible to continue and develop. Overall, investing in a larger fleet provides more promising economic prospects for fishermen

Snakehead (Channa striata) is one of the popular freshwater commodities in Indonesia, but its cultivation is still relatively low due to its relatively slow growth. Biofloc technology, which relies on microorganisms such as probiotic bacteria, is a potential solution to increase cultivation efficiency. This study aims to evaluate the effect of using various types of probiotics in the biofloc system on the growth of cork fish and to determine which type of probiotic is most effective. The research was conducted at the Cultivation Technology Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Universitas Riau, for 56 days from August to October 2024. The method used was experimental with a completely randomized design (CRD), using four treatments (P0 = control, P1 = Probio-7, P2 = Multi-Cell, P3 = Aquaenzyme) and three replications. The results showed that probiotics had a significant effect on growth parameters. The best treatment was P2 (probiotic Sel Multi), which produced the highest absolute weight (2.97 g), absolute length (3.63 cm), specific growth rate (2.02%), lowest feed conversion ratio (1.65), and highest survival rate (86.66%).

Catch per Unit Effort (CPUE) analysis assesses fishing productivity and indicates fish stock abundance in waters. CPUE values represent the ratio between catch and fishing effort. This study aims to determine CPUE values and analyze the production factors influencing catch. The research method used a survey method with purposive sampling techniques. Data were analyzed using CPUE analysis, multiple linear regression, and classical assumption tests. The results showed that tuna fishing production at PPS Bungus during the 2018–2023 period reached 1,053.09 tons, with catches dominated by skipjack tuna and yellowfin tuna. The highest CPUE value occurred in 2019 at 1.49 tons/trip, and the lowest in 2022 at 0.86 tons/trip. The production factors that significantly influenced catch yields were the number of crew members, engine power, and captain experience, while vessel size and trip duration had a negative influence. The coefficient of determination (R²) value of 0.356 indicates that the research variables only explain part of the variation in catch results. This finding underscores the importance of optimizing production factors and managing fishing efforts to sustain tuna fishing productivity at PPS Bungus

Lake Bokuok is an oxbow lake located in Aursati Village, Tambang District, Kampar Regency, Riau Province. This lake has undergone changes due to human activities, affecting the existence of aquatic organisms, including plants and fish. This study aims to determine the relationship between aquatic plants and fish in Lake Bokuok. Data collection was carried out in February-March 2025 using a survey method. Aquatic plant samples were collected once for species identification and four times for density calculations, while fish samples were collected four times for fish count calculations. The study results showed differences in aquatic plant density and total fish numbers across the three stations. Among the three stations, four aquatic plant species and four fish species were identified. Station III had the highest aquatic plant density and relative density (57.32 Ind/m²), which also correlated with the highest fish count (59 individuals). Conversely, Station II had the lowest aquatic plant density (25.08 Ind/m²) and the fewest fish (33 individuals). Statistical analysis showed a positive correlation between aquatic plant density and fish abundance, though the relationship was not statistically significant. Water quality in the lake is still considered suitable for supporting aquatic organisms. This study provides an initial overview of the role of aquatic plants in supporting fish life in natural lakes. These results are significant as a basis for water management and the development of sustainable conservation policies to maintain the ecological balance of Lake Bokuok

Gastropods are mangrove organisms that act as bioindicators in mangrove ecosystems. Mangroves are called productive areas because they are rich in organic matter, which is a source of food and shelter for various biota, such as molluscs and other organisms. Human-induced pressure will cause damage to the mangrove ecosystem. The destruction of the mangrove ecosystem will affect the life of all biota that live in it, including gastropods. This study aims to determine the density and distribution pattern of gastropods in the mangrove area of Concong Dalam Village. This research was carried out in August-September 2024 in Concong Dalam Village. The method used in this study is the survey method. The data obtained is then calculated and analyzed. The results of the study show that there are 11 species of gastropods, nine genera, and six families, including Potamididae (3 types), Neritidae (2 types), Littorinidae (2 types), Ellobidae (1 type), Melogenidae (1 type), and Muricidae (1 type). The six types of mangroves found in this study are Rhizophora apiculata, R. mucronata, Bruguiera cylindrica, Avicennia alba, Sonneratia alba, and Nypa fruticans. The density value of gastropods obtained in Concong Dalam Village ranges from 2.67 – 11.39 ind/m2. The distribution pattern found in Concong Dalam Village is uniform, with an id value of 0.31-0.44. The density of mangroves in Concong Dalam Village ranges from 600 to 1967 p/ha, with the damage criteria being very good

Global warming is one of the natural phenomena that impacts the flow of the Siak River. Among the impacts are sea level rise and seawater intrusion. These changes also affect the distribution of flora and fauna from the sea into the River. This study aims to determine the structure of mangrove vegetation communities and water quality conditions found in the tidal area of the Siak River. This research was conducted in October 2024. The research location consists of 4 stations, each station was placed in 3 plots following the flow of the River, with a distance of 100 m between each plot. Each plot has a size of 10 x 10 m. This research was conducted using the survey method. The study identified six mangrove species, consisting of 2 true mangroves and four associated mangroves. The density of mangrove vegetation in the research location is categorized as good, with the highest number of 1933.33 ind/ha at stations I and II, and the lowest at 1633.33 ind/ha at station IV. The results of the critical value index indicate that Sonneratia caseolaris plays a vital role in all research stations, with the highest percentage of 252.90% at station II and the lowest 230.20% at station I. The results of the ANOVA test analysis of density between stations showed a significant value. 0.148, which states that there is no significant difference between the four stations. Water quality measurements showed a temperature value of 28-30 °C; salinity 0 ppt, and pH 5.4-6. Sediment types at all stations were dominated by mud. The highest average organic matter was in station I, at 11.90%, while the lowest was in station II, at 6.83%. The value of Total Suspended Solid (TSS) at the study site ranged from 0.0153 to 0.1640 mg/L. Station II was dominated by muddy sand, and station III was dominated by sand with a total sediment organic matter content of 0.46-23.33%. The nitrate content found ranged from 0.0146-0.0583 mg/l, and the phosphate ranged from 0.0465-0.0996 mg/L. The linear regression test results for mangrove density with TSS, organic matter, and nutrient (nitrate and phosphate) content showed a weak relationship

Open-access fishery resources encourage fishing competition that can cause stock decreases and overfishing; therefore, bioeconomic management based on sustainability potential and utilization rate assessments is needed to maintain sustainability. This research aims to determine anchovies' potential and utilization rate (Stolephorus sp) at the UPTD Fishery Port Region I, Carocok Tarusan, West Sumatra Province. The research was conducted in December 2024 using secondary data in the form of annual catch and fishing effort for 2016-2023, obtained from relevant institutions. The methods used were the Catch Per Unit Effort (CPUE) and surplus production models of Schaefer and Fox. Based on the results of the analysis, the Schaefer surplus production model was the most appropriate model for analyzing the potential of anchovies at the Carocok Tarusan Fishing Port. This model estimates MSY at 445,211.65 kg/year with an optimum effort of 6,547 trips/year. JTB is estimated at 356,169.32 kg/year. During the research period, the average utilization rate of anchovies reached 54%, showing that fish stocks were in a moderate state. This means anchovy resources have not been overexploited and can still be utilized optimally. The exploitation rate of 33% indicates that there are still opportunities to increase fishing efforts while continuing to apply the principles of sustainable management.
