Abstract

This study aims to determine the type and density of gastropods, the density of seagrass, seagrass closure. It also knows the association gastropods in seagrass ecosystem in the waters of the Senggarang Besar. The research was conducted by random sampling method using a point 31 transect squares measuring 1x1 meters for observation gastropods and seagrass. Results of the study were found 12 species of gastropods. Gastropod density values range between 0.35-2.94 individual/m2. Results of research on the type of seagrass found 4 species of seagrass that is, Enhalus acoroides, Thalassia hemprichii, Halodule uninervis and Syringodium isoetifolium.

Abstract

Halophila ovalis is one of the pioneer seagrass species. The physico-chemical factors of the waters greatly influence the life processes of the seagrass. This study aims to compare the morphometric characteristics and growth of H. ovalis seagrass on water quality in several coastal areas in Bintan Island. Observation of morphometric characteristics includes measurement of rhizome diameter, leaf length, leaf of width, root length, internode length and number of leaves. Observation of growth rate was done by using the cutting method for leaves and marking method for rhizome. Observations of the growth rate were carried out twice, namely on the 14th and 28th days. The results showed that the H. ovalis type of seagrass found at Dompak Station had greater morphological characters than other stations. The condition of the bottom substrate is related to the morphological characters of the seagrass. The growth pattern of the seagrass leaves for one month of observation has a decline in growth trend. The rhizome growth pattern at all observation stations has an increasing trend. The results of the principal component analysis and correspondence analysis show that environmental parameters such as substrate type and nutrient concentration have a role in the morphological structure and growth of H. ovalis.Keywords:BintanGrowthHalophila ovalisMorphologySeagrassABSTRAKHalophila ovalis merupakan salah satu jenis lamun pionir.

Abstract

Kawal Waters is one of the waters in Bintan which has good fishery resources, one of that is the blue swimming crab. The Blue Swimming Crab (Portunus pelagicus) is one of the important economic fisheries resources belonging to the Portunidae family. The blue swimming crab is one of the most common organisms used by the community. The purpose of the study was to determine food composition of blue swimming crab (Portunus pelagicus) in Kawal waters of Bintan Island, Riau Island on June 2021. The sampling used random sampling method. There were 34 individuals used for food composition analysis. The  food  composition  in  the  stomach  of blue  swimming  crab  consisted  of three groups of microalgae, crustacea, and detritus. The food composition in the adult size was found microalgae groups with the percentage composition 78%. It was followed by crustacea of 18,06%, and detritus of 5,12%. The highest of indeks of stomatch contens is in morning caught of 1,15 for males and 1,28 for female.

Abstract

The waters of the Sei Carang estuary are water areas that are influenced by tides and have mangrove vegetation along the waters. However, with the conversion of land functions such as bauxite mining and logging activities, the existing mangrove ecosystem is damaged. The purpose of the study was to determine the ecological characteristics of the mangrove ecosystem and to determine the level of ecological suitability of the mangrove ecosystem as a mangrove rehabilitation area in the Sei Carang estuary waters, Tanjungpinang City. This study used a purposive sampling method at 4 stations selected based on land openness and locations that allow for rehabilitation. Parameters in this study include mangrove type, substrate, salinity, tidal type, pH, current velocity, and biota objects. Based on observations, there were 10 types of mangroves found. The results of observations that have been calculated using the mangrove rehabilitation land suitability matrix show that each station can be said to be suitable for the rehabilitation area with the distribution of the suitability value of mangrove rehabilitation land showing a dominant suitability of S1 (Highly Appropriate).

Abstract

Seagrass ecosystem is a coastal ecosystem where seagrass grows as the dominant vegetation and can live permanently below sea level. Of course, the existence of human activities that do not care about the coastal environment has an impact on changes in seagrass communities in supporting coastal ecosystems. This study aims to determine the structure of the seagrass community in Terkulai Island Waters, Tanjungpinang City, this research was conducted in May 2023. Determination of the sampling point was carried out using the purposive sampling method with 4 stations that have seagrass distribution. Observation of seagrass was carried out using the modified line transect method where the line transect was placed at the starting point where seagrass was found until the end point was not found, the transect placement was chosen based on the longest area of the seagrass stretch and as a benchmark the transect placement was squared 50 x 50 cm then each line transect length was divided by 10% to get the squared distance between transects. The results of the study found 3 types of seagrass in the waters of Terkulai Island namely Enhalus acoroides, Thalassia hemprichii, Halophila ovalis. Seagrass Thalassia hemprichiii has the highest density when compared to other seagrass species with density values ranging from 764 to 1928 shoots/m2. If categorized, the value of seagrass cover at each station is included in the medium category. For seagrass biomass the Enhalus acoroides type is larger when compared to other seagrass species. The results of PCA (Principal Component Analysis) showed that seagrass cover was closely related to the environmental parameter characteristics of depth, brightness, salinity.
