Abstract

A study on the diversity of zooplankton in the Kandis River was conducted from January 2014. This research aims to understand the type and abundance of zooplankton in the Kandis River . There were three stations with 3 sampling points in each station. Samples were taken 3 times, once a week and they were analyzed in the marine productivity Riau University.Result shown that the phytoplankton obtained were consist of 6 species, they were belonged to of 2 classes, namely Rotifera (4species), Cilliata (2 species). The average of fitoplankton abundance was around 220-319 ind/l. General water quality parameters are as follow: temperature: 290C, brightness: 30-32,5 cm, current speed: 0,08-0,12 m/s, pH: 5, DO: 35–3,7 mg/l, CO2: 11,88–12,9 mg/l.Keywords: Diversity.

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

A study on the diversity of plankton in the part of upstream Siak River wasconducted from Mei-Juli 2013. This research aims to understand the abundance anddiversity of plankton in that area. There were three stations with 3 sampling points ineach station. Samples were taken 3 times, once a week and they were analyzed in theAquatic Ecology and Environmental Management Laboratory of the Fisheries andMarine Science Faculty, Riau University.Result shown that the phytoplankton obtained were consist of 25 species, theywere belonged to of 3 classes, namely Chlorophyceae (10 species), Bacillariophyceae(7 species), and Cyanophyceae (8 species). The average of fitoplankton abundance wasaround 1261-2540 cells/l. The most common phytoplankton was Planktonema sp.(334 cells/l, Chlorophyceae). Diversity index (H') was 2,91–3,07, equitability index (E)was 0,90–0,95 and dominancy index (C) was 0,05–0,08 and result shown that thezooplankton obtained were consist of 10 species, they were belonged to of 3 classes,namely Rotifera (5 species), Ciliata (3 species), and Copepoda (2 species). The averageof zooplankton abundance was around 414-530 inds/l. The most common zooplanktonwas Notholca sp. (88 inds/l, Rotifera). Diversity index (H') was 2,08-2,27, equitabilityindex (E) was 0,90–0,99 and dominancy index (C) was 0,11–0,12. General waterquality parameters are as follow: temperature: 29,3-30,3 0C, brightness: 30-33 cm,current speed: 0,11-0,18 m/s, pH: 5-6, DO: 3–3,4 mg/l, CO2: 8,98–10,98 mg/l, nitrate:0,11–0,14 mg/l and phosphate 0,015–0,019 mg/l. Based on plankton abundance, theSiak River can be categorized as oligotriphic river.Keywords : Plankton Abundance, Phytoplankton, Zooplankton, Upstream Siak River

A study on the diversity of plankton in the part of downstrem Siak River wasconducted from May to Juli 2013. This research aims to understand the abundanceand diversity of phytoplankton in that area. There were three stations with 3 samplingpoints in each station. Samples were taken 3 times, once a week and they wereanalyzed in the Aquatic Ecology Laboratory of the Fisheries and Marine ScienceFaculty, Riau University.Result shown that plankton obtained were of 23 genus species, they werebelonged to of 3 classes, namely Bacillariophyceae (6 species), Chlorophyceae(9 species), Cyanophyceae (8 species). The average of phytoplankton abundance wasaround 1083 – 1911 cells/l. The most common phytoplankton was Diatoma sp.(316 cells/l, Bacillariophyceae). Diversity index (H') was 2,88 – 2,99, equitabilityindex (E) was 0,08 – 0,92 and dominancy index (C) was 0,04 – 0,77 and result shownthat the zooplankton obtained consist of 10 genus, they are belonged to 3 classes,namely Rotifera (5 jenis) Ciliata (3 genus), Copepoda (2 genus).

Abstract

This Research aims to discover the types and density of aquatic plant in RengasLake, Buluh Cina Village, Siak Hulu Sub-regency, Kampar Regency, Province of Riau.This research was conducted on January until April 2013. This research uses SurveyMethod with doing both observing and sampling. Samples were taken 3 times, once aweek and they were analyzed in the Picology Laboratory of the Fisheries and MarineScience Faculty, University of Riau.Result shown that there are 3 classes, 6 families and 6 species of aquatic plants.There are Eicchornia crassipes, Vetiveria zizaniodes, Salvinia natans, Ipomoeaaquatica, Myriophyllum brasilliense, and Cyperus esculentus. From those aquaticplants, the species that has the most value of density is Eucchornia crassipes (54 - 82cells/m2) and the least value of density is Myriophyllum brasilliense (20-66cells/m2)Based on data obatained, Eucchornia crassipes is relatively the most denseaquatic plant (16 - 28%) and Myriophyluum brasillense is the least (7-19%).Keyword: Aquatic Plant, Density, Rengas Lake
