Abstract

Freshwater crabs have a life cycle entirely in freshwater and play an essential role in the food chain as both omnivores and detritivores. Some freshwater crabs can only be found in clean water, so they can also be used as bioindicators of water quality. This study aims to determine the habitat and density of crabs in the Tanduk River in Rumbio Village and to investigate the relationship between environmental parameters and the density of P. pardus crabs in this area, Kampar District. The study was conducted from March to April 2024 in Rumbio Village, Kampar District, Kampar Regency, Riau Province. The methods used were surveys and literature reviews. The survey method involved direct field visits to the study site. Sampling was conducted three times over a three-week period. The literature review involved collecting secondary data from previous studies and data obtained from local government offices. Primary data consisted of field data, including crab samples that were collected and identified, as well as water quality data. The study found that the density of P. pardus crabs in the Tanduk River in Rumbio Village was 10 individuals at Station 1, 16 individuals at Station 2, and 29 individuals at Station 3. Various factors, including environmental conditions like vegetation and food availability, influenced this. The habitat characteristics supporting the survival of P. pardus crabs based on water quality measurements in Rumbio Village during the study were temperature 27–28°C, turbidity 12–50 cm, pH 7.5–8.5, dissolved oxygen 5.7–7.2 mg/L, free CO₂ 5–17 mg/L, and phosphate 0.0730–0.1327 mg/L.

Abstract

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

Abstract

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

Abstract

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.

Abstract

One of the current problems for coastal areas is the high level of plastic waste. This waste degrades into microplastic particles, which can threaten the life of marine biota, including the lokan (G. erosa). Lokan (G. erosa) is used as a bioindicator to study the type and content of microplastics in the mangrove ecosystem. The purpose of this study was to analyze the differences in microplastic abundance between stations and microplastic content between sea turtle sizes, as well as the relationship between shell length and meat weight with microplastic content. This study was conducted from December 2024 to February 2025 in Kedabu Village, Meranti Islands Regency, which directly borders the Malacca Strait. The survey method was used, purposive sampling at three stations: the conservation mangrove area, the mangrove area near the fishing port, and the mangrove area near the settlement. Sea turtles were taken during low tide, each one using a machete. Individual per station. The study results showed that three types of microplastics were found in the lokan (G. erosa): fiber, film, and fragments, with an average of 32.73 particles per individual. There was a significant difference in microplastic content between small and large sea turtles, but microplastic abundance between stations did not differ significantly. The highest microplastic abundance was found at Station 1 (11,331 particles/g). Shell length and meat weight showed a moderate positive relationship with microplastic content

Abstract

The utilization of Indian scad (Decapterus russelli) in Carocok Tarusan has made an important contribution to fishing activities, but data on the potential and rate of utilization are limited. The research aims to determine the potential and level of utilization of indian scad (Decapterus russelli) landed at UPTD Fishery Port Region I, Carocok Tarusan, West Sumatra Province. The research was conducted in December 2024 using secondary data from the institution on catch and fishing efforts for 2019-2023. Methods used are Catch Per Unit Effort (CPUE) and surplus production models of Schaefer and Fox to estimate the maximum sustainable yield (MSY) and optimum fishing effort (f-optimum). According to the analysis results, the Fox model is the most suitable model to describe the stock status and management of indian scad in this region. MSY was estimated at 234,653.74 kg/year with an optimum effort of 1,902 trips/year. Total allowable Catch (TAC) was 187,722.99 kg/year. The average utilization rate was 97%, which shows that the Indian scad stock is fully exploited. Meanwhile, the average level of effort at 110% showing that fishing effort exceeds the optimum level, meaning that more careful management is needed to ensure the sustainability of the stock

Abstract

Tilapia (Oreochromis niloticus) is one of the main commodities in freshwater aquaculture because it is highly adaptable and easy to breed. In intensive aquaculture systems, production success is highly dependent on fish growth, which is closely related to feed availability and water quality. This study aims to analyze the effectiveness of modern aquaculture technologies, namely the biofloc system, aquaponics, and the Recirculating Aquaculture System (RAS), in supporting the success of tilapia aquaculture. The research was conducted in August 2025 at the Freshwater Aquaculture Center of the Sibolga College of Fisheries, North Sumatra. The research method used a completely randomised design with four treatments and three replicates. The results showed that the aquaponics technology (P3) produced the highest absolute weight growth (9.97±0.02 g), specific growth rate (4.26±0.00%/day), and absolute length (1.77±0.06 cm), followed by RAS (P2), control (P0), and biofloc (P1). The survival rate across all treatments ranged from 95.33% to 97.33%, indicating Tilapia's good adaptability to various farming systems. Water quality parameters were within optimal ranges: 29-30°C, pH 6.1-7.6, dissolved oxygen 4.5-5.0 mg/L, and ammonia 0.0001-0.0005 mg/L. The aquaponic system showed the most stable water quality with the lowest ammonia concentration (0.0001-0.0003 mg/L). This study demonstrates that aquaponic technology provides the best treatment for modernised intensive tilapia farming
