Abstract

Productivity and estimation of fishing season index in marine areas are very much needed to facilitate fishermen's fishing operations, so they are practical and efficient. This research was conducted from February 28, 2024, to March 9, 2024. This research was conducted at the UPTD Fishing Port Region I (PPW1), Carocok Tarusan, West Sumatra Province. This study aimed to calculate fishing productivity and the fishing season index of anchovies (Stolephorus sp) at the UPTD Fishing Port Region I (PPW1), Carocok Tarusan, West Sumatra Province. This research is based on a survey method involving observations and collecting primary and secondary data directly at the UPTD Fishing Port Region I (PPW1), Carocok Tarusan, West Sumatra Province. The highest CPUE value of anchovies occurred in 2021, 142.66 kg/ship. The lowest CPUE occurred in 2019, at 73.30 kg/boats. The peak season for anchovy landings at PPW1 Carocok was identified to occur from April to August, as indicated by an IMP value of more than 100%. The moderate season for anchovy landings was shown to occur from January to March and September to December, as indicated by an IMP value of more than 50%. No month was identified as a lean season where the IMP value was less than 50%.

Abstract

This study was conducted in August 2024 in the coastal area of Sri Tanjung Village, Rupat Sub-district, Bengkalis Regency. The objectives of this research were to identify the types and abundance of microplastics, examine the differences in microplastic abundance across sizes, analyze the relationship between microplastic abundance and size (shell length and total weight), and explore the relationship between microplastic abundance in Meretrix meretrix clams and sediments. A survey method was used. Random sampling of M. meretrix was carried out using small shovels and traditional fisher tools (iron rakes) during the lowest tidal conditions. Results indicated that water quality parameters in Sri Tanjung were relatively good, with temperatures of 28–31°C, salinity ranging from 21–26%, brightness values between 19–25 cm, and pH values of 7–7.7. Types of microplastics found in M. meretrix and sediments in the coastal area included fragments, fibers, and films, with an average microplastic abundance of 55.16 particles/g and 1310 particles/kg, respectively. The abundance of microplastics was categorized based on the morphometric size of clams: small (61.32 particles/g), medium (45.01 particles/g), and large (59.16 particles/g). Sediments showed an average abundance of 1310 particles/kg. Fragment-type microplastics were the most dominant in both clams and sediments, with average abundances in small clams (29.22 particles/g), medium clams (21.29 particles/g), large clams (62.27 particles/g), and sediments (541.3 particles/kg). Film-type microplastics were the least abundant, with average values in small clams (14.44 particles/g), medium clams (10.80 particles/g), large clams (13.05 particles/g), and sediments (319.3 particles/kg). A one-way ANOVA test revealed significant differences (p < 0.05) in microplastic abundance between small and medium and medium and large clams but not between small and large clams (p > 0.05)

Abstract

Microplastics are small pieces of plastic that can pollute the environment. This study aims to determine the types of microplastics in the digestion of freshwater kijing based on different stocking densities and water depths. This research was carried out from February to April 2024. Using the experimental method with a one-factor Group Random Design. Sampling of the kijing was observed after 2 weeks of laying according to the specified depth, and then the abundance of microplastics in the digestion of freshwater kijing was examined. Water quality parameters are measured by temperature, brightness, and pH. The study found five microplastic types: fiber, fragments, films, granules, and pellets. The most common type of microplastic found at all three different depths is the type of film. The microplastic abundance found at all three depths in order is 5.2, 5,4 and 6 particles/ind. From the ANOVA results, the depth has a p-value of 0.00850, which means that the p-value > 0.005 does not show any difference between depth data. While the p-value of the treatment is 0.00084, this means that the p-value of <0.005 is the difference between the treatment data. Treatments consisting of 1kg, 2kg, and 3kg had different abundance data in each treatment. This means that there are significantly different results by the treatment of microplastic abundance data in freshwater mussel

Abstract

Streptococcus agalactiae is a pathogen that causes significant losses in tilapia (Oreochromis niloticus) aquaculture. One alternative control is the use of natural ingredients such as fermented herbs. This study aims to analyze changes in the histopathological structure of the gills and liver of tilapia fish fed with feed containing fermented herbs after being infected with S. agalactiae. The research was conducted from March to December 2023 at the Laboratory of Parasites and Fish Diseases, Faculty of Fisheries and Marine Sciences, Universitas Riau and Bukittinggi Veterinary Center. The method used was a one-factor, completely randomized design (CRD) with five treatments and three replicates. The treatments consisted of negative control (Kn), positive control (Kp), and three feed treatments with fermented herbal medicine doses of 100 (P1), 125 (P2), and 150 mL/kg feed (P3). S. agalactiae infection was carried out on day 31 at a dose of 10⁸ CFU/mL. The results showed that the P3 treatment gave the best results, characterized by minimal damage to gill tissue (only hypertrophy) and liver (mild vacuolar degeneration) and the highest survival rate of 83.33%. In conclusion, adding fermented herbal medicine at a dose of 150 mL/kg feed can increase the immunity of tilapia against S. agalactiae infection, as shown through the improvement of organ tissue structure and improved survival

Abstract

The Kampar River has enormous benefits for people's lives, including the availability of non-renewable resources such as sand and stone, which are utilized without permission as raw materials for building. The high demand for river sand and stone and modern sand mining technology exacerbate environmental impacts, especially the width of the Kampar River. This study was conducted to determine the impact of changes in river width caused by illegal sand and stone mining activities in the Kampar River. This research uses a quantitative approach with direct observation methods, interviews, and literature studies. This research was conducted from May to August 2024 in Padang Luas Village, Terantang Village, Parit Baru Village, and Kualu Village, Tambang District, Kampar Regency. The results of this study indicate that illegal sand and stone mining activities in the Kampar River cause significant widening of the river, in addition to increasing turbidity and siltation of the river due to cliff collapse. The impact of changes in river width is worst in Parit Baru Village, which has the most mining locations compared to the other three villages. The highest turbidity value is found at station 3, and the shallowest river depth is at station 2. Illegal sand and stone mining has a real negative impact on the environment, especially on the physical condition of the Kampar River, which is marked by the siltation and widening of the river from year to year.

Abstract

Blood clams are soft-bodied animals that live sessile and obtain food by filtering (filter feeders). This results in many microorganisms accumulating in the body of the blood clams, one of which is the coliform bacteria group. Coliform bacteria are divided into two types, namely fecal coliform and non-fecal coliform. Fecal coliform comes from animal and human feces, such as Escherichia coli. According to SNI 01-7388-2009, the MPN value of E. coli bacteria for fresh Mollusca, Crustaceans, and Echinodermata is <3/g. This study aimed to calculate the density of E. coli bacteria in blood clams. This study was conducted from December 2024 to February 2025. Sampling was conducted at the lowest ebb with one transect consisting of 3 plots measuring 1 × 1m². The MPN method is a method for analyzing coliform bacteria and E. coli. The results of the estimation test obtained at station 1, namely the Tebing Dian Beach Area, ranged from 7-10 MPN/g with an average of 12.6 MPN/g and station 2, namely the "Cinta Mangrove" Tourism Area, ranged from 4-15 MPN/g with an average of 10 MPN/g. While the results of the estimation test obtained at station 1 ranged from 3-4 MPN/g with an average of 2.3 MPN/g, stations 2 ranged from 3 MPN/g with an average of 1.0 MPN/g. These results indicate that the abundance of E. coli bacteria in blood clams does not exceed the quality standards set based on SNI 01-7388-2009

Abstract

Lokan (Polymesoda expansa) is a bivalve in mangrove forest areas with important ecological and economic values. The lokan population plays a role in maintaining water quality and is a source of livelihood for coastal communities. This study aims to analyze the abundance, distribution patterns, and frequency distribution of individual sizes of P. expansa in the mangrove forest of Banglas Village, Meranti Islands Regency. The research was conducted in December 2024 using a survey method to determine station locations by purposive sampling. Sampling was conducted at three stations, each consisting of three transects with plots measuring 1 × 1 m². The results showed that the highest abundance was found at Station III (±16.33 ± 5,508 ind/m²) and the lowest at Station II (8.33 ± 2,082 ind/m²). The distribution pattern of lokan at all stations is clustered (Morisita index value> 1). The frequency distribution of individual sizes showed the dominance of sizes 3.40-3.89 cm with 21 individuals. Abundance and distribution patterns of lokan are influenced by habitat conditions, human activities, and food availability. ANOVA test results showed no significant differences in abundance between stations, but there were significant differences between subzones. Knowledge of the population structure of P. expansa is vital for sustainable resource management in mangrove ecosystems
