Abstract

Snakehead fish (Channa striata) inhabits the Sibam River that has polluted water and the Kulim River that has good water quality. As the quality of water affects the availability of food resources, it may influence the stomach content of the fish. A research aims to understand the stomach content of the fish was conducted on January-March 2017. The Index of Preponderance (IP) was calculated. There were 32 fishes from the Sibam River and 56 fishes from the Kulim River. Results shown that the main food of the snakehead fish was fish, IP value was 89% and 94% in the Sibam and Kulim Rivers respectively. Other types of food present in stomach of the Kulim’s fish were insect, bivalve and crustacean, but there was no crustacean in the Sibam’s fish. Data obtained shown that the water quality affect the availability of the snakehead fish food in general, as the fish food from the Kulim River is more various.Keyword : Sibam River, Kulim River, Stomach Content, Channa striata

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

ABSTRACT Comparative study of reproductive biology Ompok hypopthalmus from the Kampar Kiri and Kampar Kanan Rivers has been conducted on April-May 2018. As there are differences on water condition and water quality in the Kampar Kiri and Kampar Kanan Rivers, the biological aspects of the reproductive of O. hypopthalmus living in those areas might be different. Sixty one fishes (28 males and 33 females) were taken from the Kampar Kiri River and 54 fishes (29 males and 25 females) were collected from the Kampar Kanan River. Total length of the fishes captured in the Kampar Kiri River was 150-220 mm (males) and 158-235 mm (females), while those of the Kampar Kanan River were 132-242 mm (males) and 145-226 mm (females). Sex ratio of fishes in the Kampar Kiri was 1:1.2 and that of the Kampar Kanan was 1:1. All fishes captured shown trace of developing gonads. In all maturity levels, the GSI of fish from the Kampar Kiri River was higher than that of the Kampar Kanan River, they were 0.27-5.95% in the Kampar Kiri’s fishes and 0.84-5.43% in the Kampar Kanan’s fishes. The fecundity of the Kampar Kiri’s fishes also higher than that of the Kampar Kanan’s fishes, they were 2.488-14.927 eggs/fish in the Kampar Kiri’s fishes and 4.858-8.106 eggs/fish in the Kampar Kanan’s fishes. Egg diameter in the Kampar Kiri and Kampar Kanan River were similar, 0.70-1.50 mm. Based on data obtained, it can be concluded that the reproductive biology of the Kampar Kanan’s fishes was worse than that of the Kampar Kiri’s fishes.Keyword: Sex Ratio, Gonad Maturity Level, Gonad Somatic Index, Fecundity

Abstract

This study was conducted from Juni to November 2013 in The Barumun River and in the laboratory of the Fishery Biology, Fisheries and Marine Sciences Faculty, Riau University. It aims to determine the reproductive biology of the tenualosa ilisha. Sex ratio, gonad maturating level, gonado somatic index, eggs diameter, fecundity were observed visually and analyzed based on Cassei (in Effendie, 1979). While histological characteristics of the gonad was studied based on Effendie (1979).111 fishes were caught and results indicated that male and female ratio was 3,2 : 1 and it was not significantly different (X2 test). The age of maturity of males was achieved by 120 g (BW) and 160 mm (SL), while that of the female was 400 g (BW) and 270 mm (SL). The body weight may increase as the gonad maturation level increase. The range of gonado somatic index was 0,3–25,0 %. The range of eggs diameter in the 4th maturity stage was 0,2–0,9 mm in diameter. The fecundity of (number of eggs) fish with 285–495 mm (SL) and gonad weight was around 81.450–245.267 eggs. Results of histological study shown that the eggs and sperm in the gonad are on several maturity stages.Keyword : Tenualosa ilisha, Barumun river, Sex ratio, Gonadal Maturating Index, Fecundity

Abstract

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
