Abstract

AbstractOmpok hypophthalmus is freshwater fish that inhabit the Tarai River. That fish has high economic value, and it is more than Rp 60.000/kg. Information on biological aspects of this fish, including morphometric, meristic, and growth patterns, however, is rare. To understand the morphometrical, meristical characteristics and growth pattern of this fish, a research had been conducted from April-June 2018. There were 78 fishes(183-56 mm SL dan 45,32-1.23 gr BW) captured from the river. There were 25 morphological characteristics measured and 6 meristical characteristics counted. There were 7 morphometrical characteristic differences between male and female. In female fish, distance between ventral fin to the base of anal fin, height of dorsal fin, distance anal fin to the base of caudal fin, height ventral fin, and length of base caudal finare longer than those of the male, but male has longer distance mouth to the eye, and length of pectoral fin than female.The meristical characteristics were as follows: D.4, P.I.13-15, V.6-8, A.63-82, C.17-19. The length-weight relationship shown that the growth of male and female was isometric. Keywords:Sheatfish, Isometric, Morphological Characteristics, Meristical      Characteristic

Abstract

This research was conducted in August and November 2013 in the province of Riau Strait Bengkalis. The method used in this study is a survey method . The purpose of this study was to determine the potential catches Terubuk ( Tenualosa macrura ) in Bengkalis waters. The results showed that the results of the survey of the Terubuk fish were caught fishing waters Bengkalis the month from August to November 2013. Retrieved Terubuk number and size of fish caught as many as 3554 head comprising 1082 males and 2472 Terubuk tail tail Terubuk females . Terubuk fish growth speed at the time a young age faster than when the fish is old. The rapid growth of the young - old fish occurs because the energy obtained from food are mostly used for growth. In older fish the energy obtained from food is no longer used for growth, but only used to maintain it self and replace the damaged cells.The rate of death arrest ( F ) during the study period is higher than the rate of natural mortality ( M ) , so that the total mortality rate ( Z ) during the periods of the study are determined by the rate of death arrest ( F ). Terubuk fish mortality rate during the study period due to factors at the time of capture by fishing for migratory fish spawning . Terubuk endangered fish caused by two main factors : first, the seizure at the time of entry into migratory fish Strait Bengkalis, secondly, the quality of the water into a fish alive Terubuk diminishing.Keywords : Potential , Terubuk Fish , Aquatic Bengkalis

Abstract

Sibam River is one of black water rivers in Riau. It was inhabit by numerous fish species, but information on these fish is almost none. To understand the diversity of fish in that river, a study has been conducted from May to July 2015. There were 5 sampling areas, in the upstream (St I and II), middle (St III and IV) and downstream (St V) of the river. The fish was sampled using net (mesh size 0.5 cm inch), scoop net (mesh size 0.5 cm) and electrofishing. Data were then analyzed to find out the diversity (H’), evenness (E) and dominance (C) indexes. The fish sampled were identified based on Saanin (1984) and Kottelat (1993). The fish species present were consisted of 5 order, 16 families, 30 genus, and 41 species. The highest fish abundance was found in the ST III, and the most common species was Bagrichthys macracanthus. Osteochilus hasselti and Rasbora argyrotaenia were distributed evenly along the river, as they were found in each sampling area (Fi 100%). In the St I, II and V, the Diversity index values were high, while those in the St III and IV were medium. In all study areas the uniformity index values were high, while the dominance indexes were low.Keywords: Fish Diversity, Sibam River, Pekanbaru, Riau

Abstract

AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured  using a cast net, and a scoop net. There were  90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from    75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6;  DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish. Keywords: dark ring, growth ring pattern, sagita, catfish, polluted river
