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

Abstract

Guppy fish (Poecilia reticulata) inhabit polluted water, such as domestic waste-filled ditches in residential areas, as well as in rivers. These two habitats have different water qualities, which affects the growth of the fish; this is reflected in the pattern of growth rings in the otoliths. To determine the differences in growth ring patterns of otoliths in guppies living in ditches versus the river, a study was conducted in March and April 2025. Fish were caught using a scoop net once every 2 weeks, three times. The fish were measured, and otoliths were taken. They were then attached to objects made of glass and manually shaved using a smooth grindstone. The growth rings in the otolith were observed using a microscope. Results showed that 103 fish were caught, 50 from the trench and 53 from Tangkerang River. The size of the fish caught was 18-31 mm from the trench and 17-31 mm from the river. In fish with the same total length, the otoliths from the river were longer and wider (0.5-1 mm in length and 0.4-0.95 mm in width), whereas those from the trench were shorter (0.42-0.85 mm in length and 0.4-0.67 mm in width). The maximum number of dark rings on the otoliths of fish from the ditch was 3, whereas from the river, it was 4. There were 27 fish from the river and 18 fish from the trench that had no dark ring in the otolith. The data obtained show that the growth of guppies in the Tangkerang River is better than in the Purigiam Housing trench
