Abstract

The research was conducted in June 2015 in the estuary of Kampar River of Teluk Meranti Pelalawan Riau Province. The purpose of this study was to determine the content of organic materials in sediments and abundance of macrozoobenthos. The method used in this study was a survey method. The stations was determined based on a purposive sampling which consisted of 3 stations, and each station was divided into 5 plots. The results showed that the sediment in the estuary of Teluk Meranti was dominated by sandy mud with organic materials content ranging from 1.15 to 2.08%. There were two classes of Macrozoobenthos found, Bivalves and Polychaetes with abundance 46-70 ind/m2. Its diversity index (H') was low, but high in term of dominance index (C). The uniformity index value (E) showed that species spread unevenly. The relationship between organic content and abundance of macrozoobenthos indicates an intermediate correlation with Y = 90,326-21,95x (r = 0.41, R2 = 0.1696). It seems that abundance of Macrozoobenthos in this area was more influenced by other environmental factors.Key words : Organics materials, abundance, macrozoobenthos, Teluk Meranti

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
