Abstract

AbstractMystus nigriceps is a  fish that in habit the Tapung River. To understand the morphometrical and meristical characteristics and growth pattern of this fish, a research had been conducted from April to May 2018. There were 100 fishes (99.68-190.6 mm SL and 4.92-49.32 gr BW) were captured. There were 30 characteristics measured and 9 meristical characteristics counted. Results shown that there were 5 morphometrical characteristic differences between male and female. The head height, eye diameter, anal fin base, anal fin height and anal fin base length of the male are longer than those of the female. There were 2 meristical characteristic differences between male and female fish.  There was a white spot in the male’s fish tail and the shape of the male genital papila is pointed, while that of the female is blunt. The meristical characteristic of the fish were as follow: D.I.5-7; P.I-II.8-22; A.5-9; V.5-10.1; C.16-23.Mystus nigriceps do not have any scale,  but it has 4 pairs of barbels, 2 pairs in the  maxilla  and 2 pairs in the mandible.The length-weight relationship shown that the growth of male and female was similiar, it was negative allometric with  b=2.59in male and b=2.31in female. Keywords: Catfish, Morphological characteristics, Meristicalcharacteristic, growth pattern

Abstract

Abstract Madong Village is one of the coastal areas that is overgrown by vegetation in the form of seagrass which is a habitat for marine life, among other is gastropods. The presence of community activities around the seagrass ecosystem might affect the quality of waters and organisms associated with the ecosystem, especially gastropods. Information about the species of gastropods in the region is still limited. To find out the species of gastropods in the seagrass ecosystem of Madong Village, this research was conducted in March-April 2019. There are      3 research stations, and each station has 3 line transects with 1x1 m quadrat. The results shown that the gastropods found consisted of 5 families and 6 species, which are: Cerithium coralium, Cerithidea cingulata, Strombus canarium, Strombus urceus, Pyrene scripta, and Nassarius crematus. The conditions of the water quality obtained ware temperature ranges from 30-32º C, current speed 0.15 m/sec, dissolved oxygen 6.7-6.9 mg/L, acidity (pH) 8, salinity 31-35 ‰. The type of substrate at Station I and II is muddy sand, while Station III is sandy mud. Keywords: Madong Village, seagrass ecosystems, gastropods species,Cerithium coralium, Strombus urceus.

Abstract

Pandan Beach is inhabit by marine organisms, including mollusc. A research aims to determine species types and diversity of mollusc in the Pandan Beach was conducted on December 2015. Mollusc samples were collected 2 times from 3 stations. In each station, 5 quadrans (1x1 m) were placed randomly and mollusc present inside the quadrans were removed. The mollusc captured were identified based on Abott (1991) There were 17 mollusc species present, 7 species Bivalves and 10 species Gastropodes. The most common species was Saturnia corpulenta (The Important Value Index 59.45%). The rarest species was Daphanella elata, Polinices helicoides, Acteocina caniliculata, Fulgurofosus grabau, Tapes itterata. The diversity index (H’) ranged from 1.912 – 2.680, the evenness index (E) was 0.274 – 0.389, the dominant index (C) was 0.276 – 0.999, and the similarity index was 0.35 – 0.61. Based on data of obtained, it can be concluded that the Pandan Beach is suitable to support the live of mollusc.Keyword : Saturnia corpulenta, mollusc diversity, Pandan Beach

Abstract

Osphronemus gouramy Lac is one of freshwater fish that inhabit the Pinang Luar Lake. This fish is the most common fish in the lake, but information on its stomach content is rare. A research aims to understand the stomach content had been conducted from March-April 2017. Sampling was conducted once/ week for a one month period. There were 67 fishes captured. Stomach contents were analyzed as a basis for calculating the Preponderance Index (PI). The analysis was conducted using the gravimetric method. Results shown that in all fish captured, the content of the stomach consists of aquatic plant stem, leaves, fish scales and insect remains (shell and legs). The main food of O. gouramy is plant materials (94%). Based on the data obtained, this fish can be categorized as herbivore.Keyword : Gravimetric, Herbivore, Osphronemus gouramy, Oxbow Lake

Abstract

The Air Hitam River was inhabit by numerous fish species, information on these fishhowever is almost none. To understand the composition of fish in that river, a study hasbeen conducted from February to March 2014. There were 3 sampling sites, in theupstream (S1), middle (S2) and downstream (S3) of the river. The fish was sampledusing several net types (mesh size 0.1 – 1.0 inch), electrofoshing and line fishing. Datawere then analyzed to find out the diversity (H’), evenness (E) and dominance (C)index. The fish sampled were identified based on Kottelat (2013). The fish speciespresent were consisted of 34 species (15 families). There were Notopterus notopterus,Cyclocheilichthys apogon, Desmopuntius gemellus, D. hexazona, Esomus metallicus,Hampala macrolepidota, Labiobarbus leptocheilus, Osteochillus vittatus, Parachelaoxygastroides, Rasbora argyrotaenia, R. einthovenii, R trilineata, Tynnichthyspolylepis, Trigonopoma gracile, Pterygoplichthys pardalis, Ompok rhadinurus,Pseudeutropius brachypopterus, P. moolenburghae, Mystus nigriceps,Hemirhamphodon pogonognathus, Poecilia reticulata, Monopterus javanensis,Pristolepis grooti, Oreochromis niloticus, Anabas testudineus, Helostoma temminckii,Belontia hasselti, Osphronemus goramy and Sphaerichthys osphromenoides,Trichopodus leerii, T. trichopterus, Trichopsis vittata, Channa lucius and C. striata.The most common fish was Pterygoplichthys pardalis that was present mainly in theS2. Trichopodus trichopterus and Trichopsis vittata were distributed evenly along theriver, as they were found in each sampling area (Fi 100%). In the Air Hitam River, thehighest H’ value (3. 671) and the highest E value (0.880) were in the upstream, whilethe highest C (0.476) was in the middle stream.Keyword: Freshwater fish composition, Air Hitam River, Pekanbaru, Riau

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.
