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

Sungai Selari Village is an area in Riau Province that features a high density of water activities, including a port where many fishing boats are moored and also serves as a transportation route for fishermen seeking fish. This activity can cause water pollution, which leads to the silting of waters through sedimentation. The activity of sediment input into a body of water can cause changes in the ecosystem, including alterations in sediment texture, organic matter content, and the abundance of macrozoobenthos biota. One organism that can be affected by differences in ecosystems is the macrozoobenthos due to its sedentary nature. This study aims to determine the type of sediment, grain size, and organic matter content, as well as their relationship with macrozoobenthos abundance. This research was conducted in March and April 2023, utilizing purposive sampling techniques at four stations in total. The samples taken were sedimentary substrates and macrozoobenthos. The results indicated that the size of the dominating sediment stalk, specifically the mud fraction, ranged from 14.72% to 71.25%. The types of macrozoobenthos found are grouped into two classes, namely Gastropods and bivalves. Individual abundances range from 0.3 - 4.4 ind/m2, with the highest abundance occurring at station 4 and the lowest occurring at station 1. The organic matter content ranges from 9.27- 34.2%. The relationship between organic matter content and macrozoobenthos abundance exhibits a moderate correlation of 0.506. The relationship between sediment grain size and macrozoobenthos abundance shows a fairly close correlation of 0.544

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

Abstract

The purpose of this study was to determine the differences in catch results of wire traps (temilar) between daytime and nighttime operations. The research was conducted in the waters of the Kumpeh River, Tarikan Village, Muaro Jambi Regency. The method used in this study was experimental fishing and simple random sampling with 15 replications, using two treatments: daytime and nighttime operations. Based on the results of the survey, nine species of fish were caught. The dominant species was the lambak (Labiobarbus ocellatus), with a total of 212 individuals and an overall catch of 814 individuals obtained during nighttime trap operations. The heaviest catch was the tembakang (Helostoma temminckii), with an individual weight of 7,266 grams and a total weight of 28,871 g, also obtained from the use of wire traps (temilar) at night. The t-test results showed a significant difference (P < 0.05) in both the number and weight of catches between daytime and nighttime wire trap (temilar) operations. Based on these findings, it can be concluded that nighttime operation of wire traps (temilar) yields higher catches, both in number and total weight, compared to daytime operations
