Abstract

Macroalgae are the main competitors for coral reefs in fighting for aquatic ecological space in coral reef ecosystems. The purpose of this research; Knowing the condition of the aquatic environment, the abundance and cover of macroalgae, and the potential of macroalgae for indicators of coral reef management in the coastal waters of Katapang Village. Data on the physical condition of the waters were measured in situ while macroalgae data for each research station were obtained using the LIT (Line Intercept Transect Method). Macroalgae taxa were identified using an identification guide book from FAO (1998). The distribution of each type of macroalgae was mapped spatially based on the distribution conditions of the macroalgae at each study station. The results showed that the condition of the waters of the coral reef ecosystem in Katapang Village was supportive for the growth of macroalgae. The macroalgae found came from 3 orders, 4 families, 5 genera and 8 species. The results also indicate that the abundance and cover of macroalgae determines the shift in dominance in reef ecosystems so that these two factors can be used as indicators of coral reef management.

Abstract

Molluscs, especially bivalves and gastropods, make an important contribution to the formation of food chains in seagrass ecosystems. In addition, bivalves and gastropods are often used as biological indicators of aquatic environmental quality in seagrass ecosystems. The close relationship between seagrass beds, bivalves and gastropods can be seen in the expanse of seagrass ecosystems found on Buntal Island which is located in Kotania Bay, West Seram Regency. The potential of bivalves and gastropods, such as the diversity and community structure found in Buntal Island waters, is very important to study because the information is limited. This study aims to determine the diversity of bivalves and gastropods in the seagrass ecosystem of Buntal Island and to determine the community structure of bivalves and gastropods which include; density and relative density, abundance and relative abundance, and frequency of presence and relative frequency of presence. The research method used is quantitative. The results of the analysis of the potential of molluscs showed that the diversity of the composition of mollusc taxa found in seagrass ecosystems on Buntal Island was divided into 2 classes, 25 families, 37 genera, 52 species with a total of 3291 individuals. The mollusc with the highest score in terms of density, abundance, and frequency of presence belonged to Nassarius globossus.

Abstract

Coral reefs are one of the most ecologically productive and diverse ecosystems. This study aims to determine the condition of scleractinian coral cover in the northern coastal waters of Ambon Island. Data collection in the field is carried out using the systematic sampling method. A quadrant measuring 1x1 m2 becomes the sampling area. Quadrants are placed on transects 20 m long with quadrant intervals on transect lines of 5 m (0, 5, 10, 15, and 20 m). The transects are placed parallel to the shoreline at depths of 3 m and 10 m, with four transects at each depth, and the distance between transects is 1 m. The data obtained were then analyzed to see the percentage of coral cover in each category and component. The results showed that the percentage of the benthic substrate of coral reefs on the North Coast of Ambon Island to a depth of 3 meters was dominated by rubble with a percentage of 26.33% - 54.83%, and for a depth of 10 meters the percentage value of ruble was 11.33% - 48.83% and sand (4% - 54.50%). The category of Acropora corals both at a depth of 3 meters and 10 meters dominated by Acropora branching (ACB), while the non-acropora category is dominated by Coral Branching (CB), Coral Encrusting (CE), and Coral Massive (CM). Overall, the condition of live coral cover on the North Coast of Ambon Island is categorized as in poor condition.

Abstract

The mangrove ecosystem on Parang Island is one of the important habitats in supporting the productivity of the surrounding waters. Therefore, an analysis of the condition of the mangroves on Parang Island is very important to understand the status and trend of changes in the mangrove ecosystem, so that appropriate conservation and management strategies can be formulated. This study aims to determine the physical-chemical parameters of the waters, analyze the density, percent cover, and status of the mangrove ecosystem in the waters of Parang Island. Mangrove data was collected using the belt transect method, while the physical and chemical parameters of the waters were measured in-situ by making observations at 4 research stations. The results showed that the average water temperature at each station ranged from 29.5°C, the average salinity was 26 ppt, the average current speed was 0.24 m/s, the average pH was 5.25, and the average clarity was 73.18%. There are 4 species of mangroves in the waters of Parang Island, namely Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, and Bruguiera gymnorhiza. The highest average relative density in the tree category is owned by Rhizophora apiculata, and the lowest is represented by Brugueira gymnorhiza. The highest sapling category is represented by Rhizophora stylosa, and the lowest by Brugueira gymnorhiza, while for the seedling category, the highest relative density is represented by Rhizophora apiculata, the lowest by Sonneratia alba. The highest average mangrove cover is owned by the Rhizophora apiculata species, and the lowest is represented by the Brugueira gymnorhiza species. The condition of the Rhizophora apiculata mangrove is in a moderate status, while Rhizophora stylosa, Sonneratia alba, and Brugueira gymnorhiza species are in a rare status.
