Abstract

This research was conducted in April 2021 to analyze organic matter content in the sediment and the abundance of macrozoobenthos. The purpose of this study was to analyze the content of organic matter in sediments and their relationship with the abundance of macrozoobenthos in the waters of the Pakning River, Bengkalis Regency, Riau Province. Sediment and macrozoobenthos samples were taken from the waters of the Pakning River, Bengkalis District, Riau Province. The method used in this research is a survey method. Sampling was determined using purposive sampling at four different stations. The results of this study indicate that the organic matter content of sediment in the waters of the Pakning River has a percentage of 6.73-12.76%. The highest organic matter content is at station 1 of 12.76% and the lowest organic matter content is at station 4 of 6.73%. The highest average abundance of macrozoobenthos was 19.26 ind/m2 at station 1 with the dominant species being Anadara granosa. Connection between organic sediment and abundance of macrozoobenthos has a linear regression equation y = 1.8442 +0.1662x with a coefficient (R2) of 0.1491 which means that the effect of organic matter in the waters of the Pakning River is 14.9% while 85.1% is influenced by other factors. The value of 0.38 indicates that the relationship between organic matter and the abundance of macrozoobenthos is, a moderate relationship

Abstract

Aeromonas hydrophila bacteria often attack internal organs such as the liver and intestines. This research was conducted in June – August 2021 at the Laboratory of Fish Parasites and Diseases, Faculty of Fisheries and Marine, Universitas Riau. Histology preparations were made at the Bukittinggi Veterinary Center. This research aimed to obtain the best dose addition of papaya leaf fermented solution which could reduce intestinal and liver tissue damage of striped catfish (P.hypophthalmus) which was challenged with A.hydrophila. The method used is an experimental method with a completely randomized design (CRD) with 4 treatment levels and 3 replications; Kp (Feed not given papaya leaf fermented solution + infected with A.hydrophila), P1 (16 ml/kg feed of papaya leaf fermented solution + infected with A.hydrophila), P2 (16 ml/kg feed of papaya leaf fermented solution) + infected with A.hydrophila), P3 (16 ml/kg of papaya leaf fermented solution feed + infected with A. hydrophila). The fish used was 8-10 cm with a density of 1 fish/3 L totaling 10 fish with a container measuring 40x30x30 cm. Infection by injection in the intramuscular section as much as 0.1 mL/head with a bacterial density of 108 CFU/mL. The parameters observed were clinical symptoms for 72 hours and histopathology of the intestine and liver of striped catfish. The results showed that the intestine saw the presence of hemorrhage, necrosis, and edema. While the liver shows abnormalities, such as hemorrhage, necrosis, hypertrophy, and fatty degeneration.

Abstract

Organic matter has an important role in marine ecology and it can be used as an indicator of water fertility. The content of organic matter in the waters in a certain amount can be useful for aquatic biota, but if it exceeds the acceptable threshold for the environment and organisms, it can cause disturbances. The content of organic matter in the waters will increase due to waste from households, agriculture, industry, and organic waste from land that is carried into the waters. Various community and industrial activities both on land and waters in the South of Bengkalis Island can provide input of organic matter in the waters. The method used in this research is a survey method that is carried out directly in the field to collect data and samples which are then analyzed. This study aims to determine the content of organic matter in water and sediment and analyze their possible relationship. The results showed that the organic matter content of the water ranged from 34.36 – 35.96 mg/L and the organic matter content of the sediment ranged from 4.78 – 13.78%. The content of organic matter in the waters has not exceeded the quality standard threshold. The results of a simple linear regression test showed a positive relationship with an R2 value of 0.712, which means that the relationship between the organic matter content of water and sediment is quite strong (71.2%). The types of sediment in the southern waters of Bengkalis Island are the mud type

Abstract

This research aims to determine the description of the presence of macrozoobenthos which is thought to have been affected by coastal stockpiling which has recently been carried out around the Mandeh Tourism Area. This research was conducted in January - March 2022, the method used in this research is purposive sampling with sampling using the transect method. The results of this study indicate that the water quality of Nagari Mandeh is sufficient to support the life of macrozoobenthos, the macrozoobenthos found consist of 10 families, namely Arciidae, Cardiidae, Cerithiidae, Fasciolariidae, Neritidae, Potamididae, Psammobiidae, Tellinidae, Turbinidae, and Strombidae. The type of sediment in the waters of Nagari Mandeh consists of gravel sand, colloid, sandy silt, silty sand, and sandy gravel. The content of total organic matter (BOT) from sediments in the waters of Nagari Mandeh was found to be in the range of 8.08% - 15.25% (medium). Coastal reclamation activities do not have an impact on the presence and diversity of macrozoobenthos but have an impact on the types of individuals living around the reclamation area

Abstract

Multi-cell probiotic containing bacteria Nitrosomonas sp., Nitrobacter sp., and Bacillus sp. This research was conducted from March to May 2021 at the Fish Disease and Parasite Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Riau University. This study aimed to analyze the hematology of Asian redtail catfish reared in media that was added with probiotics periodically and to obtain the best time interval for giving probiotics to the rearing medium. The method used in this study is an experimental method by applying a Completely Randomized Design (CRD) with five treatment levels and three replications. The treatments used were the administration of probiotics at a dose of 0,01 mL/L of water with different time intervals, P0 (without treatment), P1 (5 days once), P2 (10 days once), P3: (15 days once), and P4 (20 days once). Fish were reared for 50 days. The results show that the Asian redtail catfish reared with the addition of probiotics in the rearing medium had a significant effect (P<0.05) with the best time interval being once every 5 days in the P1 treatment, seen from the total erythrocytes 2.43 x 106 cells/mm3, hematocrit level 28.67%, hemoglobin level 7.40 g/dL, total leukocytes 9.92 x 104 cells/mm3, leukocrit level 1.83%, and glucose 49.67 g /dL. Water quality during the study was still in the normal range that could support the growth of Asian redtail Catfish, namely temperature 26-27.1 C, pH 5.8-6.5, DO 6.0-7.4 mg/L, and ammonia 0.0011-6.5 0.0047 mg/L

Abstract

The waters of Lubuk Gaung Village, Sungai Sembilan District are areas that are widely used as transportation routes. Activities in these waters will cause environmental pollution, which affects the life of phytoplankton. The purpose of this study was to determine the relationship between the primary productivity of phytoplankton with oceanographic parameters in the waters of Lubuk Gaung Village, Sungai Sembilan District, Dumai. The method used is the survey method to determine the research station and the in situ method for measurement and sampling of oceanographic parameters. The results obtained are Oceanographic parameters from the three research stations, namely Brightness = 30 – 49 cm, Turbidity = 47.4 – 58.4 FTU, TSS = 124 – 209 mg/L, and BOD = 0.408 – 1.224 mg/L. The average value of primary productivity of the waters ranged from 48.07 to 79.69 mgC/m3/day. The value of primary productivity at station II is categorized into Oligotrophic, namely low waters. Stations I and III are categorized into mesotrophic waters, namely medium waters. The relationship between brightness, turbidity, and TSS with primary productivity has a very strong and positive (unidirectional) correlation value. The relationship between BOD and primary productivity has a very strong and negative (opposite) correlation.
