Abstract

ABSTRACT  Trichopsisvittata is one of the freshwater fish that commonly present in Riau, including in the Riau University Dam and the main ditch of the PERUMDAM housing complex. Information on the biological aspects of these fish, including the morphometric, meristic and growth patterns, however, is rare. To understand the morphometric and characteristics of these fish, a study was conducted from October-December 2019. The fish was sampled from 2 locations, namely in the Riau University Dam and in the main ditch of the PERUMDAM housing complex, 4 times, once/ week. There were 200 fishes captured, 100 fishes from the dam and 100 fishes from the ditch. They were 29-54 mm SL and 4.12-5.7 g BW. Twenty six morphological characteristics measured and 11 meristic characteristics were studied. Results shown that the meristic characteristics are as follows D.II.6-8, P.6-8, V.5-10, A.VI-VII.24-28, C.11-13.The number of scales in the dorsal fin was 12-18 in the cheek was 8-9, around the body was 38-40, in the tail basewas 14-16, above the lateral line was 6-8 and below the lateral line was 10-12. There were 3 differences of morphometric characteristics between male and female of Trichopsisvittata. In male, the distances betweenmouthand the base of the pectoral fin, the abdominal fin to the base of the anal fin and the length of the anal fin is longer than those of the female’s. The length-weight relationship of female (b = 0.222) and the male (b = 0.302) was negative allometric. Keywords:freshwater fish, negative allometric, growth patterns, fish morphology

Abstract

ABSTRACTHemibagrus nemurus  is a type of freshwater fish that inhabit the Kampar River that has relatively good water quality and in the Siak River that has been polluted. As water quality affects the health status in general, the morphometric, meristic and growth pattern of H. nemurus  living in those river might be different. To understand the morphometric, meristic and growth pattern of this fish, a study has been conducted on April-June 2018. There were 63 fishes (114.65-340 mm TL and 13.56–279.93 g W) from the Kampar River and 54  fishes (154.37-320 mm TL and 32.12–222.76 g BW) from the Siak River. The were 29 characteristics measured and 6 meristical characteristics counted. The meristical characteristics were as follows: D. I.7, P. I.6, V.6, A.10-11, C.20-22. In general, there was almost no significant different in morphological characteristics of fish from both sampling area, but the fish from the Kampar River shown that their body was wider than that of the Siak’s fish. The length-weight relationship of H. nemurus from both sampling sites were b= 3.2  (positive allometric,  Kampar River) and b = 2.4 (negative allometric, Siak River).Keywords: Catfish, Morphological Characteristics, Meristical Characteristic, Growth Patterns.

Abstract

 AbstractPangasius polyuranodon is present in the Pinang Luar lake. Residue of palm plantation activities such as fertilizer, pesticide as well as soil particles may enter the water and negatively affect the health of fish in general. A study aims to understand the histological structure of the gill, kidney and liver of the fish   has been conducted in December-February 2021. Fish organs were histologically processed and stained with HE. Abnormality and damage of the gill was noted and categorized using Histological Alteration Index. Results shown that the types of abnormality present were hyperplasia, hypertrophy and necrosis. In the gills of 2 fishes, there were Dactylogirus sp and Myxobolus sp parasites that may caused the gill damage. The HAI value of the fish ranged from 1 to 102 (category I – III),  indicates that the gill of P. polyuranodon from the Pinang Luar lake is categorized as normal to  high damage. The histological structure of kidney and liver are normal. In general, histological structure of the gill, kidney and liver of the fish from the Pinang Luar lake are healthy.Keywords:Secondary Lamella, Hyperplasia, Histopathological Alteration Index, Dactylogirus sp.

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

Abstract             Rasbora caudimaculata is a type of freshwater fish that inhabits the Tanjung Kudu and the Teluk Petai Lakes, Kampar Regency. A study aims to understand the type of food in the stomach of the fish was conducted in October – January 2021. Samplings were carried out 4 times, once/2 weeks. The fish was caught using nets with mesh size 0.5 inch and 1 inch. There were 321 fishes (169 fishes from the Tanjung Kudu Lake and 152 fishes from the Teluk Petai Lake).  There were 58 fishes with empty stomach and they cannot be analyzed. The analysis of stomach content was conducted using a volumetric method. The stomach content data obtained were used as a basis to calculate the Preponderance Index (PI). The types of food present in the fish’s stomach from both sampling areas were similar. The main food of R. caudimaculata from both   lakes is insects, PI 55% from the Tanjung Kudu Lake and PI 46% from the Teluk Petai Lake. The complementary foods were phytoplankton (Bacillariophyceae, Chlorophyceae, Cyanophyceaea, Euglenoidea, Trebouxiophyceae, Xanthophyceae dan Zygnematophyceae) and rotifers. R. caudimaculata has viliform teeth and short firm gill rakers. The length of intestine was 1.2 times of total length. Data obtained indicate that R. caudimaculata is an omnivorous fish.Keywords: Oxbow lake, Feeding habit, Omnivorous fish, Preponderance Index
