Abstract

This research was conducted in June 2013 at Riau River Estuary inTanjungpinang City Riau Islands Province. This research aimed to find out themacrozoobenthos community structure and its relationship to seagrass vegetation.The method on the research was survey method. The existence of macrozoobenthosin this area showed the dynamic symbiosis among seagrass and marine organisms.The results also showed seagrass ecosystem had the high potential to be managed andused by communities and also increasing the fisheries productivity on coastal area.Species composition of macrozoobenthos in the area consisted of 8 species, i.e.Strombus sp, Cerithidea quadrata, Pina bicolor, Anadara sp, Anadara inflata,Atactodea striata, Asteroidea sp and Diadema sitosum. Two species of seagrassvegetation were found in this area, those were Enhalus acoroides, and Halophilaovalis. T-test analysis showed that the average of macrozoobenthos abundance oneach station differed unsignificantly (p>0,05). The regression analysis showed thatrelationship among seagrass vegetation diversity and macrozoobenthos abundancewas at r=0,35.Keywords: Riau River, Macrozoobenthos, Seagrass, Symbiont.

Abstract

The study to observe the species composition and abundance on mudskipper fish was conducted in July 2013 in Dumai coastal waters of Riau Province, Indonesia. They study was carried out in providing the lack information on the biological aspects of the mudskipper from Indonesian seas in general, and of the riau’s coasts in particular. They study used a survey method by selecting 3 different stations as the sampling sites. Fish sampels were collected during the low tide. The quadrant were used in the field in facilitating the survey in fish abudance, whilst the identification was commenced in the Laboratory of Marine Biology of University of Riau. The resuld showed that a number of three species of the mudskipper were sucessfully recorded, i.e. Periopthalmodon schlosseri, Periopthalmus variabilis (Eggert) and Baleopthalmus boddarti (Pall). In terms of abudance, the highest, 0,1733 individuals/m2 was recorded in station I and the lowest 0,0867 individuals/m2, was found in stations III. Based on the diversity index (H’), it was reported that the Dumai coast had moderate diversity of the mudskipper. None of the fish was dominating the population since the dominance index (C) was very close to null from each station. It can be concluded that the habitats of mudskipper in Dumai coasts were in the state of unstable due to its E value in which also close to one.   Keywords : Mudskipper, species composition, abudance, Riau.

Abstract

The research was conducted in October 2012-January 2013 to study thegrowth, defoliation and biomass of mangrove seedling of Bruguiera sexangula whichwas contaminated by crude oil in Pangkalan Sesai Village of Dumai in Riau Province.The research used experimental method by direct observation on the field. The resultsshowed that treatment with different concentrations of crude oil, gave a significantimpact to the growth, leaf number, height, defoliation and leaf biomass of mangroveseedlings. Increasing diameter, stem biomass and root biomass of Bruguiera sexangulawas, however, not impacted by crude oil. Higher crude oil concentration added to theseedling lowered the growth and gave higher defoliation in mangrove Bruguierasexangula seedling.Keywords : Dumai, Crude Oil, Biomass, Defoliation, Growth, Bruguiera sexangula
