Abstract

Sok-sok Holbung is a small shallow river in the Dolok Imun plateau with a very good quality of water. A research aims to understand the species, diversity and domination indices of fish in that river had been done from September-October 2016. There were 3 stations, in the upstream, in the middle and in the downstream area of the river. The fish was sampled using scoop net and then they were identified based on Saanin (1968), Kottelat (1993) and Fowler (1940). Samplings were done 2-3 times in each station. Results shown that there were 3 ordos, 4 families, 5 genuses and 5 species fish present in the study area, they were Mystaccoleus padangensis, Tor soro, Homaloptera ripleyi, Channa striata, Clarias batrachus. The diversity index ranged from 0.443- 0.765, while the dominant index was 0.388-0.757. The most common species was H. ripleyi that was present in each sampling site.Keyword: Sok-sok holbung River, Ichtyofauna, Homaloptera ripleyi, Tor soro

Abstract

Parit Belanda River is a branch of the Siak River and is inhabited by many typesof aquatic organisms, but the scientific information of those organisms is almostnone. To understand the types of prawns present in that area, a study has beenconducted from November 2015 to February 2016. There were 3 sampling areas,in the upstream (St I), the middle area (St II) and in the downstream (St III).Prawns sampling were conducted one /week for a month period, using a net(mesh size 0.5 cm) and scoop net (mesh size 0.5 cm). Morphometrical andmeristical data of the prawns were then analyzed descriptively. The prawnssampled were identified based on Cay et al. (2004) and Wowor and Choy (2001).Result shown that prawns sampled was few, there were only 30. The prawnsspecies present were consisted of 1 species only, Macrobrachium equidens Dana,1852 (Palaemonidae). This species characterized by slightly bent upward rostrum.Rostrum, propodus and telson of the male are longer than those of the female.Keywords : Macrobrachium equidens, prawn, Parit Belanda River

Abstract

Stripped flying barb fish (Esomus metallicus) is common in the waters around the Riau University. A study aims to determine the stomach content of the fish was conducted in May 2017. There were three sampling areas, the earthen pool around the Rektorat Building (Station 1), dam (Station 2), and a stream in the back of Marine Science Building (Station 3). Sampling was done three times,  once/week. The fish was captured using a scoop net. Total number of fish sampled was 40. Results shown that the main food of the fish is phytoplankton (IP>40%), the complementary food is detritus (IP 4-40%), and additional food is zooplankton and crustacean remains (IP<4%).Key Word: E.

Abstract

Trichogaster pectoralis is a root grazer fish and it may be used to control the population of aquatic weeds such as Eichhornia crassipes. To understand the ability of the fish in controlling the weed, a laboratory scaled research has been conducted from April-May 2016. There were 5 treatments applied, namely ±25 grams fish (Bm25), ±50 grams fish (Bm50), ±75 grams fish (Bm75) that were reared in 25 liter tank completed with ±150 grams E. crassipes. As controls, ±150 grams weed was reared in tank without any fish (Ke150) and ±50 grams fish (Ki50) was reared in tank without weed. Results shown that T. pectoralis was able to control E. crassipes population. Each treatment speed up the decrement of E. crassipes population, but the best result was shown by Bm75. In this treatment, the population of E. crassipes reduced into 95.33 grams by the 28th day.Keywords: Trichogaster pectoralis, Eichhornia crassipes, root grazer, weed control

Abstract

Dam and streams around the University of Riau is inhabited by many types of aquatic organism, including prawns. Scientific information of those organisms, however, is almost none. To understand the types of freshwater prawns present in that area. A research has been conducted from February to April 2017. Sampling areas were in the dam, pond and streams around the University of Riau. Freshwater prawns sampling were conducted once/week for a month period. Prawns were caught using a scoop net (mesh sixe 0,5 cm). Morphometrical and meristical characteristics of the prawns were then analyzed descriptively. The prawns sampled were identified. There were 106 prawns. The freshwater prawns species present were consisted of a single species only, namely Macrobrachium tolmerum, Riek, 1951 (Palaemonidae). This species characterized by schapocherite length that is shorter than rostrum length, rostral teeth sub-equally spaced, 8-10 teeth in the dorsal and 4 teeth in the ventral of rostrum. In male, the rostrum, propodus, carpus and merus are longer than those of the female.

Abstract

Anabas testudineus is freshwater fish that commonly inhabit streams, rivers and canals in Riau. This fish is relatively cheap protein sources for people. However, information on biological aspects of this fish is limited. To understand the stomach content analysis of this fish, a study has been conducted from January – March 2014. The fish was sampled in the irrigation canals of the palm plantation area, using fish trap and line fishing. Stomach content of the fish was analyzed to calculate the Preponderance Index (PI).Total, there were 106 fishes captured, but 31 of them had empty stomach and could not be used for stomach content analysis. The number of fish analysed was 69. Results shown that the main food of A. testudineus was phytoplankton, namely Chlorophyceae (PI 89.00%), Bacillariophyceae (PI 4.42%) and Cyanophyceae (PI 5.36%). The most common Chlorophyceae present in the stomach was Ulotrix sp (PI 87.6%). Zooplankton was rare and the there was only remains of Crustacean (PI 1.22%) present in the stomach. Based of data obtained, it can be concluded that main food of A.testudineus is phytoplankton and the fish can be categorized as plankton feeder.Keyword : Anabas testudineus, Canal, Stomach Content Analysis, Index of Preponderance

Abstract

Pristolepis grooti (Anabantidae) is a freshwater fish that commonly present in the flooded swamp area along the river and also in the dam. This fish has relatively low economical value, but it is protein source for villagers. Information on biological aspects, including the type of food consumed by the fish is rare. To understand the stomach content of the fish, a study has been conducted from February to April 2015. The fish was sampled from the swamp area in the Bencah Kelubi Village and from the Koto Panjang Dam, 6 times, once/ week. The stomach content of the fish was then identified and the Preponderance Index (Natarajan and Jhingran, 1961) was calculated. Results shown that the main food of fish from those sampling sites are different. The main food of the Koto Panjang fish was fish feed pellets remains (PI 56.53%) , while that of the swamp fish was insects (98.67%). Data obtained from this research shown that P. grooti is able to consume many types of food available.Keyword :Pristolepis grooti, Koto Panjang dam, Bencah Kelubi, stomach content, fish feed pellet.

Abstract

Helostoma temmincki is a freshwater omnivorous fish and it can be found in theTapung River swamp and in the Sail River. The water quality in the Tapung River swampis relatively good condition, while the water quality in the Sail River is bad it is polluted.As the water quality in general affects the blood condition of the fish, it is predicted thatblood condition of H. temmincki from the Tapung River swamp and the Sail Riverdifferent. To understand blood condition of H. temmincki from both areas, this study hasbeen conducted from February to March 2015. There are 9 fishes from the Tapung Riverswamp and 9 fishes from the Sail River. The fish blood was taken and analyzed forerythrocytes and leukocytes content, hematocrite and leucocrite levels and types ofleukocytes present. Results shown that the erythrocytes of fish from the Tapung Riverswamp was 2,658,889 cells/mm3 and that of the Sail River was 2,318,889 cells/mm3. Thenumber of the leukocytes of the Tapung River swamp fish was 176,389 cells/mm3 and thatof the Sail River fish was 200,056 cells/mm3. There were 5 types of white blood cells inH.temmincki, namely lymphocytes, thrombocytes, monocytes, basophiles, and neutrophils.Based on data obtained it can be concluded that the blood condition of H. temmincki fromthe Tapung River swamp was better than that of the Sail River.Key words: Tapung River swamp, Sail River, Helostoma temmincki, blood
