Abstract

This study wasconducted inFebruary - April2012 in Buatan Lake Waters Pekanbaru City.Theaimed of this study was to determine of the pollution level of Buatan Lake waters base onofphysical, chemicalandbiological parameters. The method used was surveymethod.Samples were takenat4 (four) stationsand5 (five) pointseach stationwith samplingintervaloftimeoncea month. The result of this study showed that physical and chemicalparametersweretemperature 28.7 to 30.8°C, depth 1.4 to 3m, the brightness 46.3 to 70.9cm, pH5.7 to 6,dissolved oxygen 1.11 to 1.55mg/l, BOD54 to 5mg/l, COD 26 to 32mg/l, TSS39 to 48mg/l,total organic matter in the sedimen 22 to 33%, and most of the stasions dominatedbymudsubstrat.Macrozoobenthosfoundas many as3(three) species (Tubifexsp, ChironomusspandHesperocorixasp). The average of macrozoobenthosabundance was791 ind/m2. Base onstatistical analysis (Anova)found that no significant differences abundance between stasionsFcalc.≤ Ftab.was 0.90<4.76), as well as between months. It could be conclude that BuatanLake waters had been heavily polluted, only a few high tolerance organism could be survive.

Abstract This research was conducted in February-April of 2019 in Pulo Pane waters of  Sosorgadong District in Central Tapanuli  Regency of North Sumatra Province. The aims are to determine the community structure of bivalves includes: Species, abundance, relative abundance, diversity index, uniformity index, dominance index, similarities index and patterns of distribution. Sampling was done by using line transect method at 3 stations. The result found 6 families with 6 species of bivalves namely Anadara antiquata, Trachycardium subrugosum, Atactodea sp., Crassostrea sp., Donax sp.and Polymesoda erosa. The abundance value was in the range of 3.87 to 9.80 Ind/m2. Diversity index values ranged from 0.73 to 0.79 is relatively low, whereas the uniformity index values ranged from 0.69 to 0.77 that was categorized in balance condition, dominance index values ranged from 0.48 to 0.64 indicating there was a species dominantly, similarity index values ranged between 91-100% indicating nearly similar pattern.

Abstract

This study was conducted in December 2013 at Dumai river estuary. Thestudy aims were to determine the abundance distribution of mangrove snail (T.telescopium) and correlation between abundance and sediment organic content.The method used was a survey method. Samples of snail population and sedimentwere collected by a single visit during low tide. Location of study was dividedinto 3 stations. Station I located inside the conservation area, station II waslocated close to shipyard, while station III laid near by a residential community.The analysis carried out in Marine Biologi Laboratory of Riau University.The results of the study show that the highest abundance of snail was atthe station III (6,55 ind/m2) and the lowest was at the station I (1,99 ind/m2).Statistical analysis (Anova) show that there was no significant differentabundance among those stations. Regression analysis show that the relationshipbetween the abundance of T. telescopium and organic sediment content wasnegatively correlated (r = 0,453).Keywords: Telescopium telescopium, abundance, organic Sediment, Dumai Riverestuary

Abstract

This research was conducted in March 2014 in the coastal waters of the Village of Kuala Enok of Indragiri Hilir Regency in Riau Province. The purpose of this study was to determine the level of bacterial contamination of E. coli as an indicator of pollution on “tembakul” (P. schlosseri) fish in the coastal waters of Kuala Enok. Tembakul fish sampling conducted at three observation station, station I is located in the territorial waters adjacent to residential, station II is located in the creek waters, and station III is located in the open sea waters. Samples of “tembakul” fish were analyzed by using the MPN method three series tube at the Laboratory of Microbiology and Biotechnology of Fisheries and Marine Sciences Faculty of University of Riau. The yield on the analysis of the sample gills, digestive tract and fish meat tembakul showed that at the settlement waters and the creek waters the number of bacteria was 1,100 MPN/g but had differences on the meat at the open waters with an average of 747.67 MPN/g. The results showed that the innoculation of bacteria growing at the time of isolation was from the coliform group. Total coliform values ​​at each point of observation station was above the food quality and safety standards required by BSNI 7388: 2009 and BPOM (Agency for Food and Drug Administration) of the maximum contaminant limits in food is 10 MPN/g in fresh meat.

Abstract

Density and distribution population of sea urchin Diadema setosum was conducted in May 2014 at Setan Island. The research aimed to know about its density and distribution pattern. The study used survey method by applying transect and plot. The location of research was covering 3 stations. The stations were chosen base on existence of sea urchin D. setosum on coral reef (reef flat). Transect drawn from 5 m up to 15 m depth during low tide. There were there three plots with a size of 3x3 m² along the transect .The results showed that the sea urchin numbers was 332 individuals, where the density range value was 1,367 individuals/m2. The highest density was recorded at station I and the lowest density was found at station III. Morisita indeks dispersion showed that the location had a uniform distribution (Id<1), except for station III had a clumped distribution (Id>1). The highest size frequency of sea urchin D. setosum was ≤2 cm dan the lowest was 4,1-6 cm.Keywords: Setan Island,Density, Distribution,Diadema setosum

Abstract

Mudskipper is included family Gobidae of class Actinopterygii.Geographically, these fish are widespread and abundant in tidal areas andestuaries. This study was conducted in July 2013, located in Sesai Village Dumaicoastal waters. This study aims to determine the type of food consumed byMudskipper, especially those inhabiting coastal waters of Dumai. The methodused in this study is a survey method. Samples obtained from the field and thenanalyzed in the laboratory. Water quality parameters measured includetemperature, salinity, soil pH, water pH, and DO (Dissolved Oxygen). Samples offish used in this study were divided into 3 groups of size, which the size of 0-70mm, 71-140 mm in size and length of 140 mm. From stomach contents analysisshow that mudskipper consume ten types of food that consists of molluscs(Alocinma longicornis and Onicomelania hupensis chiur), crustaceans(Holometopus haematocheir), Fish (Periopthamus and Harpodon neherous),Insecta (Psepenus herricki and Oecophylla smaragdina), Cyanophyceae(Gloetricha echimulata) and Angiosperms (Najas japonica Nakai). From theresults of ANOVA test, there was no significant different between the types offood consumed by fish of different sizes. The value of Relative Important Index(IRP) proves that the main food type of Mudskipper from Dumai coastal waters isHolometopus haematocheir (Crustacea). It can be concluded that the Mudskipperfish are carnivores.Keywords: Food Habits, Mudskipper, Coastal Waters, Dumai
