Abstract

AbstractSibam River is inhabit by small sized prawns. Scientific information of those organism, however,  is almost none. To understand the types of prawns present that area, a research has been conducted from April to May 2017. There were 3 sampling areas, in the upstream (St I), the middle area (St II), an in the downstream (St III). Prawns sampling were conducted once/week for a month period, using a scoop net (mesh size 0.5 cm). Morphometrical and meristical characteristics of the prawns were analyzed descriptively and te prawns sampled were identified. There were 65 palaemonids prawns captured and they were identifed  Macrobrachium. Detail identification showed that they were Macrobrachium mammilodactylus (15 specimens, 9 males and 6 females) and Macrobrachium heterorhynchos (50 specimens, 6 males and 44 females). M. mammilodactylus charactererized by schapocherite length that is shorter than rostrum length, 7-18 teeth in the dorsal and 2-6 teeth in the ventral of rostrum, all segments except fingers with abundant short mammiliform protective setae. M. heterorhynchos charactererized by carapace and glabrous abdomen, without microspinules. In males, rostrum one-third distal extending beyond scaphocerite, 8-9 teeth in the dorsal and 4 teeth in the ventral. In female, rostrum just reaching end of schapocerite, 8 teeth in the dorsal and 5 teeth in the ventral.Keywords: Sibam River, freshwater prawns, Macrobrachium mammilodactylus, Macrobrachium heterorhynchos

Abstract

Climbing perch (Anabas testudineus) is the one of freshwater fishes living inRiau. Information on the biological aspect of this fish, however, is limited. Astudy aims to understand the reproductive biological aspect of this fish has beenconducted from January-March 2014. The fish was sampled once/ month for athree months period. They were 153 fishes, 68 males and 85 females, 49-145mm SL and 4-126 gram BW. Sex ratio of females and males was 1:1,25. In eachsampling, male and female fishes in 1st , 2nd , 3rd and 4th maturity stages werecaptured, and only female in 5th maturity level was captured. The gonado somaticindex (GSI) is around 0.0088%-5.8567%. Fecundity is around 4.116-13.998eggs/fish, with mature egg diameter ranged from 0.62-0.69 mm. Microscopicstudy of the ovarian structure showing that the ovary of mature femalesdominated by mature eggs and there were few amount of non vitellogenic andearly vitellogenic eggs. The atretic eggs were found in the ovary of the 5thmaturity level fish only. This structure indicates that the fish may be a totalspawner. The testes of males showing mature sperms throughout the study period,indicates this fish may be able to spawn throughout the year.Keywords: Anabas testudineus, Reproduction, sex ratio, GSI, fecundity, sexreversal

Abstract

ABSTRACTSnakehead fish (Channastriata) is one of  fish living in the SeiPaku Reservoir. Research on the stomach content analysis and feeding habits of the fish has been carried out in February-April 2019. Samplings were conducted6 times, 2 weekly.  The number of fish caught was 97. The stomach content was analyzed using  a gravimetric method and the data obtained wereused for calculating the IP value. Results shown that the type of food present in the stomach were fish, insects, plants, andnot identified debris. The main foods of the snakehead fish was fish (IP 62,72%), the complementary foods was non identified animal debris(IP 37,27%)  and there were 2 additional food, namely  insects (IP 0.001) and and plants(IP 0, 02). Based on data obtained, it can be concluded that C. striata is a carnivore fish. The water quality of the reservoir were as follows: temperature 28oC-32oC, brightness of 26.15-58 cm, pH of 6, disolved oxygen of 3-5 mg/L adn cabondioxide 5.99-7.99 mg/L. Keywords: Carnivorous fish, Preponderance Index, Gravimetric, Cork fish

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

AbstractMystus nigricepscommonly inhabit the Tarai River that has been polluted  and it may affects the reproductive biology of the fish. A study aims to understand the reproductive biology of M. nigriceps has been conducted. The fish was sampled        5 times, once/two weeks, from April to July 2019. Parameters measured were Sex Ratio, Gonad maturity Level, Gonad Somatic Index (GSI), fecundity and egg diameter. Results shown that there were 34 males and 66 females (sex ratio 1:2). Male fish was indicated by the presence  of white spot in  tail and it has pointed genital papilla.  The  genital papilla of female is blunt. The size of male ranged from 73.01-140.22 mm (SL), while that of the female ranged from 59.67-160.21 mm (SL). The GSI of male ranged from 0.12 to 13.06%, while that of the female was 0.33-15.35%. The fecundity was 4.644 to 34.938 eggs/fish and egg diameter was 0.4 to 0.7 mm. The eggs in all size distribute evenly in the ovary and it indicates that this fish is a total spawner.Keywords : Catfish, Sex Ratio, Gonad Somatic Index, 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
