Abstract

Abstract Clarias batrachus is a freshwater fish that inhabit the Tapung Kiri and Sail Rivers. The water quality in the Tapung Kiri River is relatively good, while that of the Sail River is polluted. As the water quality in general affects the blood condition of the fish, it is predicted that blood condition of C. batrachus from the Tapung Kiri and Sail Rivers are different. A research aims to understand the blood condition ofC. batrachus from those rivers were conducted from February-March 2019.There were 12 fishes captured from each river. The fish blood was taken and then analyzed for the number of erythrocytes, leukocytes, hematocrit and leucocrite levels and the type of leukocyte was identified. Results shown that the number of erythrocytes, leucocyte, haematocrite and leuoccrite levels of the fish from the TapungKiri River was 2,160,000 cells/mm3, 200,833cells/mm3, 32.96% and 1.71% respectively. While those of the Sail River was 2,121,667 cells/mm3, 211,375 cells/mm3, 31.27% and 1.81% respetively. There were six types of leukocytes present in the blood of fish from both areas. In the fish from the Tapung Kiri River, there were eosinophil (5.7%),lymphocytes (72.1%), monocytes (3.6%),neutrophils (2.6%) and thrombocytes (16.0%). While in the fish from the Sail River, there were eosinophil (6.4%),lymphocytes (43.2%), monocytes (20.3%),neutrophils (6.9%)and thrombocytes (23.2%).Based on the data obtained it can be concluded that the condition of fish from the Tapung River is healthy and the fish from Sail River is unhealthy. Keywords: erythrocytes,leukocyte,haematocrite, leucocrite

Abstract

AbstractBarau fish (Hampala macrolepidota) is a carnivorous fish found in Tanjung Kudu Lake and Teluk Petai Lake. The quality of the waters in the two lakes is different, it is thought that it has an influence on the availability of food in the waters, and will make a difference to the stomach contents of the barau fish. To find out the stomach contents of barau fish, a study was carried out in October-December 2020. From the data analysis using the Index of Preponderance (IP), 55 fish samples from Lake Teluk Petai and 30 from Tanjung Kudu Lake, the results obtained shows that the main food of Barau fish is fish, with an IP value of 68.60% from the Teluk Petai Lake and 54.59% from the Tanjung Kudu Lake. Other types of food found in the stomach of barau fish are insects, plants and crustaceans. Of the two lakes, only insects, there were significant differences after statistical tests were carried out. The results above show that the water quality influences the availability of food for barau fish. Keywords: Petai Bay Lake, Tanjung Kudu Lake, Gastric Fill, Barau Fish

Abstract

AbstractThe Teluk Petai Lake is an oxbow lake that received water from the Kampar River. The lake, however, received domestic pollutant that negatively affects the water and thus affect the life of fishes, including Hampala macrolepidota living in that lake. To understand the growth ring pattern in the otolith of that   fish, a study was conducted on November to December 2020. The fish was sampled using nets with 3/4 and 2,3 inch mesh size, 4 times, once/ week. The fish captured was then measured, weighed and the otolith (sagita) was removed. The otolith was then sticked in slide glasses using Crystalbond Amber 509 and then shaved manually using whetstone to reveal the growth ring patterns. The dark ring was identified using a binocular microscope. Results shown that  among 50 fishes captured (200 – 350 mm TL,  90 – 320 gr BW), 48 fishes have dark growth rings, 1 – 3 rings/ fish. The distance between the otolith’s nucleus and the 1st  growth ring was various, ranged from 0.1 – 0.75 mm, indicating that the formation the growth ring is individual and it is not resulted from mass evidence. Based on data obtained, it can be concluded that  mostH. macrolepidota in the Teluk  Petai Lake faced problems that hampered their growth as indicated by the formation of dark rings in the otolith.Keywords: Oxbow lake, Growth pattern, Sagita, Hampala barb
