Mystacoleucus padangensis is relatively small Cyprinids that commonly inhabit theToba Lake and surrounding waters. A study aims to understand the stomach contentand its relation with size, sex and level of maturity of gonads has been done onJanuary to April 2014. There were three stations, namely the Naborsahan River(Station I), river mouth of the Naborsahan River (Station II), and the Toba Lake(Stasiun III). There were 515 fishes captured, however only 52 fishes were used forstomach content analysis study as the other having almost empty stomach (stomachfullness index less than 50%. Parameters measured were Index of Preponderance(IP), type of food based on Total Length, sex, and maturity level. Results shown thatthe main food of this fish is Rotifera (IP 41.78%). Small fishes (less than 81 mm TL)tend consume Bacilliariophyceae (76.17%), medium sized (80 – 93 mm TL) fish tendto consume Cyanophyceae (39.87%), while the big fish (more than 139 mm TL)prefer to consume Rotifera 38.27-58.38%) and Xanthophyceae (52.51%). Based onsex, the male eat more Cyanophyceae (35.60%), while that of the female Rotifera(39.86%). Fish with relatively low maturity level (2nd and 3rd maturity levels) tend toeat Cyanophyceae (82.56%) and Bacilliariophyceae (76.29%) respectively, whilemature fish prefer Rotifers (81.58%). Based on data obtained, it can be concluded thatthe diet of M. padangensis was various, and it is related to body size, sex and gonadmaturity level.Keywords : Mystacoleucus padangensis, Stomach Content Analysis, PreponderanceIndex, Sumatera Utara

Tor soro is a North Sumatran endemic species. This fish have high economic value and play important role in Batak’s culture. Biological information on this fish, including the morphological characteristic, however, is rare. To understand the information on length-weight relationship, a study has been conducted from March to June 2015. The fish was sampled from the Aek Godang River, especially in the Banuaji (St 1) and the Dolok Nauli (St 2) villages. Totally 123 fish were captured. Several body parts such as total length, head length, fork length, caudal rod length, body height and body weight were measured and then compared to standard length in order to understand the growth pattern of the fish. Results shown that the length-weight relationship of male and female was isometric (male b=3.039 and female b=3.024). The coefficient correlation (r) values of the relationship between standard length and other body parts ranged from 0.812-0.994. It’s indicate that there is very significant relationship between standard length and the length of other body parts.Keyword: Tor soro, lenght-weight relationship, Aek Godang River, North Sumatera Province

Pterygoplichthys pardalis is a type of freshwater fish that live in the Air Hitam River, one of polluted river in Riau. Eventhough the river is polluted, but this species well developed in that river. To understand the stomach content of that fish and its relationship with size, sex and level of maturity, a study has been conducted from February to May 2015. There were 169 fishes captured, however only 91 fishes were used for stomach content study as the other had empty stomach. The stomach content was analyzed and was used as a basis to calculate the Preponderance Index (PI). Results shown that the main food of P. pardalis is Bacillariophyceae (PI 41.19%), small fishes (91-124 mm TL) tend to consume Cyanophyceae (PI53.54%), while the big fish (more than 295 mm TL) tend to consume Bacillariophyceae (PI 45,48%) and rest of crustacea (PI 46,66%). Male eat more Cyanophyceae (PI 46,69%), the female consume Bacillariophyceae (PI 39,05%). Fish with low maturity level (2nd and 3rd maturity level) tend to eat Chlorophyceae (PI 48.81%) and Bacillariophyceae (PI 34.19%), while the mature fish prefer to consume Chlorophyceae (PI 37.14%). Based on data obtained, it can be concluded that the main food of P. pardalis was various and it is related to body size, sex and gonad maturity level.Keywords : Pterygoplichthys pardalis, Stomach Content Analysis, Preponderance Index

Pengambang River was inhabit by numerous fish species, however, information on type and relative density of fish in that river was almost none. To understand the type and density of fish in that river, a study has been conducted from May to July 2014. There were 6 sampling sites, in the upstream (S1-S2), middle (S3) and downstream (S4-S5-S6). The fish was sampled using several net types (mesh size 1.27 inch and 1 inch), scoopnet (mesh size 1.27 inch), gillnet (mesh size 2-7 inch) and bamboo trap (mesh size 2 inch). Samplings were conducted 4 times, once in 2 weeks. The fish collected were then identified based on Saanin (1968), Kottelat et al., (1993), Rainboth (1996), and Kottelat (2013). Relative density and the occurence of each type of fish were analyzed. Results shown that there 34 endemic fish species (14 families) were present. There were Barbodes schwanefeldi, Barbichthys laevis, Cyclocheilichthys apogon, Rasbora argyrotaenia, Rasbora trilineata, Osteochilus kelabau, Osteochilus vitatus, Parachela oxygastroides, Hampala macrolepidota, Tynnichthys polylepis, Lobocheilos schwanenfeldii, Mystus nemurus, Mystus nigriceps, Bagrichthys macracanthus, Kryptopterus lais, Ompok hypopthalmus, Wallago leeri, brachypopterus, Pangasius polyranodon, Pangasius-pangasius, Pristolepis grooti, Oxyeleotris marmorata, Helostoma temminckii, Osphronemus goramy, Belontia hasselti, T. trichopterus, T. leerii, Channa striata. C. micropeltes and Notopterus notopterus. The highest relative density (Fi 46%) was in the S5 (in the river mouth of the Pengambang River), while the lowest (Fi 31%) was in the S1 (in the upstram of the river). The most common fish present was K. lais, R. argyrotaenia, E.metalicus, O. vitatus and P.grooti that were distributed evenly along the river (Fi 83,33%). There were 4 introduced fish species found in the Pengambang River (Fi 12.5%), namely E. metallicus, C. gariepinus, O. niloticus and Trichogaster pectoralis.Keyword: endemic fish , introduced fish, Pengambang River, Pekanbaru, Riau

Pterygoplichtys pardalis has known as sapu-sapu fish. It is commonly present in the Air Hitam River. To understand the reproductive biology of this fish, a research has been conducted on February to May and November 2015. Fish samples were obtained from the Air Hitam River. Parameters investigated were fish morphology, sex ratio, maturity level, fecundity and the relationship between fecundity, length and weight. Samplings were done at three stations, in the in the upstream (Station I), middle (Station II), and downstream (Station III) of the river. Totally 169 fishes (75 males and 94 females) were captured. Sex ratio between male and female was 1:1.2. The Gonado Somatic Index (GSI) of male was 0.0022% -2.6% and that of the female was 0.03-3.4%. Egg diameter was 1.5 -3.2 mm. The fecundity is around 5,351-48,980 eggs/fish. The relationship between fecundity and standart length was y= 2.056x -0.548, fecundity and body weight was y= 0.863x +2.290. The water quality parameters are as follows: temperature 27-28.5°C, turbidity 15-22 NTU, the depth of the water 0.75-0.80 m, the width of the river 8.06 m, current speed 0.15-0.44 m/s, pH 6-9, DO 2.5-3 mg/L. Data on water quality parameters indicate that water quality in the Air Hitam River is able to support the life of the fish and the fish may reproduce well.Keyword: Pterygoplichtys pardalis, reproduction, sex ratio, GSI, fecundity, Air Hitam River
