Abstract

This research was conducted in October 2016 in the waters of Bintan Strait of Desa Pengujan of Bintan Regency of Kepulauan Riau Province. The purpose of this study was to determine the level of seagrass density, macrozoobenthic abundance and seagrass density relation to macrozoobenthic abundance in waters of Bintan Strait of Desa Pengujan. This research uses survey method and location of observation determined by Purposive sampling.The location of the observation is divided into 3 stations, the first station is adjacent to the fish seed area, the second station is between the fish seed and magrove area and the third station is adjacent to the magrove area.The number of seagrasses found in 4 species are: Enhalus acoroides, Halopila minor, Halodule uninervis, and Thalassia hemprichii, which have very high seagrass density, and identified macrozoobenthos species are 3 classes: Gastropoda, Bivalva and Asteroidea, consisting of 13 species at 3 observation stations, 7 species of gastopod class, 5 species of bivalve class and 1 species of Asteroidea class, with abundant levels of abundance. The density of seagrass to makrozoobentos abundance of 18%, while 82% influenced by other environmental factors such as physical parameters, chemistry and organic matter content in the waters.Keyword : Pengujan village, Seagrass, Macrozoobenthos

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

Nirwana beaches water is well known as recreation and harbor. Such condition apparently brings negative impacts to marine life. Corals are considered as the major component of coral reef ecosystems whose condition is influenced by environmental condition. The aim of this study is to observe the general condition of coral reefs and the distribution of stony corals in Nirwana Beaches. The study was carried out Januari until May 2017 by taking 5 stations. The method used was Line Transect and coral identification using Coral Finder. The result indicates that generally the condition of coral reef was categorized as good condition, the coral cover averaging at 51.66 %. There were 109 organism of corals found, divided into 5 species. The morisita index value of 1.764 indicates that corals are distributed in groups. The highest frequency of occurrence of coral species by Porites. Human activities cause damage to coral reef ecosystems.Keywords: Corals, Coral Cover, Distribution, Nirwana Beaches.

Abstract

This research was conducted in March 2016 in Pasumpahan Island at district Bungus, Padang city, province of west Sumatera. The purpose of this research was to know the condition of the coral reefs, such as: the percentage of living coral, variety, Uniformity, and domination based on life form of the coral. The method in this research was survey method by using Line Intercept Transect (LIT). It was consisted of three stations where each station was divided into two sub-depth (4 and 8 meters depth). The results show that the form of coral growth consisted of Acropora Branching (ACB), Acropora Encrusting (ACE), Acropora Submassive (ACS), Acropora Digitate (ACD), Acropora Tabulate (ACT), Coral Branching (CB), Coral Massive (CM), Coral Encrusting (CME), Coral Submassive (CS), Coral Foliose (CF), Coral Heliopora (CHL) dan Coral Mushroom (CMR). The condition of coral reefs in Psumpahan Island was good in the dept of 4 meter (60.70%) and in the dept of 8 meter (56.85%). Life form diversiy was moderate (H’ 2.99),while domination was low dominace (C 0.15), as well uniformity (E 0:37).Keywords : Condition, Coral reefs, Pasumpahan Island.

This study aimed to determine the rate of growth of propagules R. mucronata good at various intensities shade. The results showed growth of propagules R. mucronata significant effect on height growth, diameter, survival percentage, number of leaves and total biomass. High growth in most large propagules present in 25% shade intensity is 0,23 cm. Greatest diameter growth found in 25% and 75% shade intensity is 0,006 cm. Highest percentage of life, of all the intensity of shade. Leaf shade intensity is highest at 100% ie 1.3. Propagules greatest total biomass present in 50% shade intensity is 1.3 grams.Keywords: Riau, R. mucronata, Growth, Shade intensity

Abstract

Ciguatera Fish Poisoning (CFP), can be caused by ciguatoxin from groups such as the bhentic dinoflagellate of Gambierdiscus sp., Ostreopsis sp., and Prorocentrum sp.,the bhentic dinoflagellates potentially toxic. In addition as bhentic organisms these three bhenthic dinoflagellates also found associated with brown algae, red algae, coral fragments and also attached on seaweed . Research on the distribution of the toxic dinoflagellate benthic Sargassum sp in the coastal waters of Sungai Nipah Beach of Pesisir Selatan Regency of West Sumatra Province was conducted in April 2014 with the to analyze the abundance and distribution of benthic dinoflagellate Gambierdiscus sp. Ostreopsis sp Prorocentrum sp. The study was conducted by taking a substrate attachment of benthic dinoflagellates from the seaweed, and then put them in a plastic screen of sea water. For the releasing of the benthic dinoflagellate the process agitation and filtration were used with filter of 250μm and 20μm. The samples observed by using microscope and Sedgwick Rafter Cell. The highest abundance was found at stations with high density (45.85 cells/gram). The research showed that the abundance and distribution of toxic dinoflagellate types of seaweed in coastal waters in Sungai Nipah was more influenced by local currents.Keywords : Dinoflagellata, Distribution, Sargassum sp, West Sumatera

Abstract

The species existence of dinoflagellates , i.e. Gambierdiscus sp., Prorocentrum sp. and Ostreopsis sp in the waters can cause disease, poisoning and blooming. This will cause disruption of aquatic ecosystems that cover the water surface and light penetration into the body of water will be hampered. Research to determine the abundance of toxic dinoflagellate epibenthic on seaweed Padina sp. in Sungai Nipah waters was conducted in August 2015. Sampling of epibenthic dinoflagellates attached to Padina sp was performed in three stations and each station consists of three sampling points.The results showed that the highest abundance epibentic toxic of dinoflagellates in the coastal waters of Sungai Nipah found at station 3 (803.28 cells / g). The highest abundance from all stations was a genus of Prorocentrum sp., with the total number of 947.74 cells/g, genus Gambierdiscus sp. had the smallest abundance at each respective station with a total of 41 cells/g while Ostreopsis sp has a evenly abundance in almost every station with a total abundance 562.93 cells/g.Keywords: Abundance, Epibenthic, Dinoflagellates, Toxic, Padina sp., Sungai Nipah Waters
