Abstract

Abstract            In the swamp area of the Sawah Village, the water quality is affected by pollutant originated from activities conducted around and in the swamp area.The low quality water may negatively affects the growth of Monopterusalbus and it is reflected in the growth pattern in the otolith of fish living in that swamp. A research aims to understand the pattern of otolith growth rings of theMonopterusalbuswas conducted in March to May 2018.The fish was captured using fishing gears, once/week. There were 61 fishes (31 females, 15 transitionand 15 males). The otoliths (sagita) is taken by tweezers and shaved using fine grindstone. Growth ring pattern in the otolith was studied using a binocular microscope. The length of otolith was 2.25-4.75 mm and weight 0.0040-0.0200 gram. Results shown that the  number of dark ring in the otolith of the fish ranged from 1 to 4. The distance between the nucleus and the first dark ring was varied (0.25-1.75 mm). These data indicates that the formation of dark ring may not be affected by periodical condition but it is affected by individual problem. The number of dark ring in otolith indicate that the fish is able to live properly in the swamp areas. Keywords: dark ring, sagita, freshwater eel, eel growth

Abstract

AbstractMystus nigriceps is a type of freshwater fish that live in the Tarai river. This research aims to understand the stomach content of the fish. Samplings were conducted in the Tarai River, 5 times, once/2 weeks for a three months period. The fish was captured using nets, scoop nets and bamboo trap. The number of fish caught  was 102, but 4 fishes had empty stomach and they cannot be analyzed. The method used was gravimetric. Stomach content of the fish was analyzed as a basic to calculate the Preponderance index (PI). Results shown that the main food of the fish from Tarai River was insect (PI 71.93%), the complementary food was fish (PI 6.06%) and unidentified materials (PI 13.46%) and the additional food was plant (PI 1.36%), crustaseans (1.51%) and domestic waste (1.57%). Based on data obtained, Mystus nigriceps can be categorized as carnivore. Keyword: Catfish, Feeding Habit, Index of Preponderance, Carnivore fish

Abstract

 Abstract Pangkal Tanjung Balam Lake is inhabited by many types of aquatic organism, including prawns. Scientific information of those prawns, however, is almost none. To understand the types of freshwater prawns present in that area, a research has been conducted in March 2018. There were 3 sampling areas, in the upstream (t1), the middle area (t2), and in the downstream (t3). Freshwater prawns sampling were conducted once/week for a month period. Prawns were caught using bamboo traps. Morphometrical and meristical characteristics of the prawns were then analyzed descriptively and the prawns sampled were identified. There were 131 palaemonids prawns captured and they were identified as Macrobrachium. The freshwater prawns species present were consisted of a single species only, namely Macrobrachium mammilodactylus, Thallwitz, 1892 (Palaemonidae). This species characterized by schapocherite length that is shorter than rostrum length, 7-9 teeth in the dorsal and 2-5 teeth in the ventral of rostrum, all segments except fingers with abundant short mammiliform setae. Keywords :Pangkal Tanjung Balam Lake, freshwater prawns, Macrobrachium  mammilodactylus, mammiliform setae

Abstract

AbstractThis research was conducted in Halang Island waters, Rokan Hilir Regency in May-June 2019. The study aims to find out the morphometric variations and also the growth patterns of the mussel shells. Purposive sampling method was used in this research to determine the location of the sampling. The mussel shells sample obtained from the three stations were 506 individuals (station I were 161 individuals, station II were 175 individuals, station III were 170 individuals).  There were 5 characteristics of morphometric examined in each male and female sample, namely PL, LBC, LC, TEC, and BT. From the research results the length-weight relation shown that the growth patterns of mussel shells was negative allometric (3 > 0.041).Keywords: Variation, Corbicula Javanica, Halang Island, Growth Pattern.

Abstract

ABSTRACTHemibagrus nemurus is present in the Kampar Kiri River. A study aims to understand the reproductive biology aspects of this fish has been conducted from July-August 2019. The fish was sampled 4 times, twice/month. Parameters measured were sexual characteristics, sex ratio, gonad maturity level, gonad somatic index (GSI), fecundity and egg diameter. Results shown that there were 24 males and 28 female (sex ratio 1:1). The female has bigger body than that of the male. Gonad Somatic Index (GSI) of the male was ranged from 0.15%-0.44%  andthat of the female was ranged from 0.07% - 4.05%. The fecundity of female was ranged from 2,040 – 26,180 eggs/fish. Egg diameter ranged from 0.33 – 0.44 mm and eggs in different sizes distribute evenly in the ovary, indicating that H. nemurus is a total spawner. Keywords: Catfish, Reproduction, Sex Ratio, GSI, Fecundity, Total Spawner

Abstract

Lubuk Siam Lake is one of the oxbow lakes in the Lubuk Siam Village, SiakHulu Sub-regency, Kampar Regency, Riau Province. This lake is overgrown by varioustypes of aquatic plants and almost cover the surface of the lake. This condition hampersthe fishing activities in the lake. This research aims to discover the types and density ofthe aquatic plant in Lubuk Siam Lake and it was conducted on February to March 2015.Field sampling was done 2 times, a month period. The plants were then identified basedon Van Steenis (1981).Results shown that there were 7 species of aquatic plants present in the LubukSiam Lake and they are belonged to 4 classes, 7 families. They are Eichhornia crassipes,Salvinia natans, Ipomoea aquatica, Cyperus sp., Paspalum sp., Pandanus sp., andNephrolepis sp. The most common plant is Salvinia natans (61-71 organisms/m2,relative density 55.94-57.13 %), while the rarest was Ipomoea aquatica (4.5-7organisms/m2, relative density 3.48-6.47 %). In general, the relative density of aquaticplants in the Lubuk Siam Lake can be categorized as rare to dense.Keywords: Lubuk Siam Lake, Aquatic Plant, Density

Abstract

ABSTRACTHemibagrus nemurusis one of freshwater fish that inhabit the Kampar Kiri River. This research aims to determine type of food present in the fish’s stomach. To understand the type of food consumed by H. nemurus, a research has been conducted in July to August 2019. Sampling was conducted 4 times, once/ 2 weeks for a two months period. The fish was captured using nets. There were  65 fishes captured, but only   47 fish have full stomach. The analysis was conducted using a gravimetric method. Stomach contents was analysis as a basis to calculate the  Preponderance Index (PI). Results shown that the main food of H. nemurus is fish (PI 67%), the complementary food is plant remains (PI 13%), unidentified debris (PI 13%) and insect (PI 5%), While the additional food is crustacean (PI 2%). Data obtained indicate that H. nemurus is a carnivorous fish. Keyword: Catfish, Feeding Habit, Preponderance Index, Gravimetric Method

Abstract

Bandar Kayangan Lembah Sari Lake is a man-made lake that is used to store water for agricultural and tourism purposes. There are many aquatic plants present in the lake and to understand the types and coverage area of the aquatic plant, a study was conducted in March-April 2016. A purposive sampling method was applied in collecting the aquatic plant. The plants were then identified based on Van Steenis (1981). The map of Bandar Kayangan Lake was downloaded using Google Earth application and the aquatic plant coverage areas in each station were then measured as a basis to predict the plant coverage area in the lake. The aquatic plants found during this study consisted of 4 families and 4 species, they were Cyperus rotundus, Paspalum commersoni, Nymphaea sp., and Pandanus sp. The aquatic plants coverage in the Bandar Kayangan Lake was around 18% and it is categorized as rare. The area that is not covered by aquatic plant was around 82% (1,054.058 m2).Keyword : Bandar Kayangan Lembah Sari Lake, aquatic plant, coverage area.
