Abstract

The experiment was conducted in December 2013 in the mangroves ofDumai Riau University Marine Station. The method used in this study is a surveymethod, to make observations and field sampling. This study aims to determinethe relationship of the abundance of shellfish sipetang (Pharella acutidens) withother macrozoobenthos abundance in mangrove forests Dumai Riau UniversityMarine Station. Sampling was carried out sipetang and other macrozoobenthos inplace - a place that is found sipetang, the plot (plot) measuring 1m x 1m2,amounting to 12 and sediment samples were taken at each station.Macrozoobenthos species were found in mangroves of Dumai RiauUniversity Marine Station is Telescopium telescopium, Chicoreus capucinus,Geloina coaxans, Pitar manillae, Parasesarma cf. pictum, Uca coarctata andArenicola marina. Results for the four stations sipetang abundance in mangroveforests ranged from 6.67 to 9.67 ind/m2 while other macrozoobenthos abundanceranged from 7.00 to 9.67 ind/m2. Macrozoobenthos abundance relationships andother sipetang positive and very strong where the higher the higher the abundanceof macrozoobenthos abundance of shells sipetang.Keywords: Pariaman, macrozoobenthos, Distribution

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

Abstract

The research was carried out on the breakwater rocks in Water Conservation AreaPariaman West Sumatra Province in May 2013. The goal in conducting this study is tofind out how to survive gastropods in breakwater and sandy beach ecosystems areconstantly subjected to pressure waves. The method used was a survey method thatdirectly observe the behavior and movement of gastropods.There are 5 types of gastropods which have distinctive way of life to survive inthe face of pressure waves. Gastropods movement in the face of pressure waves in thesubmerged breakwater when high tide and exposed to the atmosphere when the low tidesas well as having an active movement, slow and settled. Life pattern gastropods in thesandy habitat gastropods will be attached to rock fragments and other fossil biota. Therewas slow movement that occurs when the wave came. Human impact on the gastropodswill always avoided by attaching themselves to the substrate tightly, closing their shellimmediately and move quickly. Gastropods movement in rock breakwater depends on thecause as something approaching movement (humans and other organisms), exposure tofree air (drought) and the most important is the availability of food.Keywords: Gastropods, survive, breakwaters, pressure waves, West Sumatera

Abstract

This study was done in June 2014 in Rindu Laut coast of Purnama Village of Dumai City. The field sampling was using the method Line Transect Plot. The mangrove in the study area had 6 families with 10 species, i.e. Xylocarpus granatum, Rhizopora apiculata, Bruguiera gymnorrhiza, Bruguiera cylindrica, Ceriops tagal, Lumnitzera littorea, Avicennia marina, Sonneratia alba, Excoecaria agallocha and Nypa fruticans. The mangrove species that dominated in this area was Xylocarpus granatum and Rhizopora apiculata. Based on the diversity, density and water quality parameters indicated the condition of the mangrove in the study area of was at the medium stage. Parameters of the environment enough to support the growth and development of mangrove forests, it can be seen from the condition of aquatic and a substrate muddy bottoms. The calculation of the value of the dominance Index (C) ranged from 0.16 to 0.58, indicating no type of mangrove species dominating the study area.Keywords: mangrove, the structure of the community, diversity, Rindu Laut, Dumai

This study was conducted in June 2013. The study aim was to the determine the diversityof gastropods in the intertidal zone of Cingkuak Island and Pasumpahan Island. Survey methodwas used to collect information related to the purpose of the study. There were 2 stations chosenalong Cingkuak Island and Pasumpahan Island. For each station there were 3 transects, whichhave 5 plot for every transect, were employed. Sample of gastropods were transported to thelaboratory for identification, counting of the individual number, and calculation of the value ofdiversity index, dominance index and equibility index.The results showed that there were 164 individual gastropods at Cingkuak Island and 90individual gastropods at Pasumpahan Island. The gastropods were comprised of 4 orders, 4families and 16 species. The most dominant species founded in Cingkuak Island andPasumpahan Island were Littoraria intermedia and Littorina vespacea. The value of diversityindex at Cingkuak Island was high and at Pasumpahan Island was medium. Value of equabilityindex was medium. Value of dominance index at Cingkuak Island and Pasumpahan Island waslow. The habitat of gastropods still supported and considered safe for macrozoobhenticorganism.Keywords: Diversity, Gastropods, Cingkuak Island, Pasumpahan Island

Abstract

This study has been done on the reefs in the coastal waters of Beralas PasirIsland. It was carried out on May 2013 by deploying LIT method. The aim of thisstudy is to find out the condition of the reefs based on the percentage of HardLiving Coral Cover (HLCC) in the area. For that instance, three stations asrepresentatives were chosen purposively. As a result, the type of reefs in the areaunder study was fringing reef with different condition on each station. The station1 and 2 showed good condition with more than 50 % of HLCC coverage. Yet, itwas in moderate condition for the third station; it was about 29.10 %. There wasno dominant life’s form that found in term of both dominancy index and diversity.Keywords : Beralas Pasir Island, Coral Reef, Condition
