Abstract

AbstractPangasius polyuranodon is one of freshwater fishes that inhabit in the Kampar Kiri (Mentulik) and Kampar Kanan (Teratak Buluh) River in Riau. Pangasius polyuranodon known as opportunist fish, but information on its stomach content is limited. A research has been conducted at October to November 2017 to understand the stomach content of this fish. Sampling  was conducted once/week for a month period. There were 88 fishes captured, but 15 of them had empty stomach and its cannot be used for stomach content analysis. The analysis was conducted using the gravimetric method. Stomach content was analyzed as a basis to calculate the Preponderance Index (PI). Result shown that the main food of the fish from the Kampar Kiri River was insect (PI 95%), the complementary food was plant (PI 4%), and the additional food was debris (PI 1%). The main food of the Kampar Kanan River was bivalve (PI 76%), the complementary food was human waste (PI 16%), and the additional food was insect (PI 3%), domestic waste (PI 3%), plant (PI 1,8%) and debris (PI 0,1%). Based on data obtained, this fish can be categorized as omnivore.Keywords: Pangasius polyuranodon, Stomach Content Analysis, Gravimetric, Mentulik and Teratak Buluh River.

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

 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
