<![CDATA[Seagrass as a high-level plant utilizes carbon dioxide to produce organic matter and stores it in biomass, so that this plant has the potential to reduce carbon dioxide pollution in the environment. This study aimed to analyze the carbon stock and carbon sequestration of two seagrass species in Waai Coastal Waters, Ambon Island. Thalassia hemprichii and Enhalus acoroides were the main focus of this research. These species are the dominant species in Waai Coastal Waters. This research was conducted in June 2019 at two research stations based on substrate differences, namely Station 1 representing a muddy substrate, and Station 2 representing a sandy substrate. The analysis of carbon stocks was carried out using a biomass analysis approach, which was divided into above the substrate and below the substrate. The analysis of carbon sequestration was carried out using the production rate analysis approach. The carbon content analysis was based on the Walkley and Black method. Based on the research results, it was found that the potential carbon stock in E. acoroides ranged from 112.38 - 126.34 gC.m-2. It was higher than T. hemprichii that ranged from 9.31 - 11.28 gC.m-2. This carbon stock was higher at below substrate, especially in the rhizome, which reached 50% of the total carbon stock. The potential of carbon sequestration was also higher in E. acoroides (1.45 - 1.81 gC.m-2.d-1) compared to T. hemprichii (0.43 - 0.54 gC.m-2.d-1). The ability of these two species to absorb and store carbon was better in the muddy substrate area because of the sufficient nutrient content.]]>

<![CDATA[Comprehensive information regarding the reproduction, early development, and growth of larvae is very important in the efforts of captive breeding and reintroduction of endangered fish species. One of the species that is starting to be threatened is the Arfak rainbowfish, Melanotaenia arfakensis which is already in the vulnerable category and its information is still relatively limited. Therefore, this study was conducted to describe the spawning activity, early development, and growth of the larvae of this rainbow fish species under laboratory conditions. Experiments on a laboratory scale were carried out in March-September 2017. The fish used came from the Nimbai Stream. A total of three pairs of individual males and females ranging in size from 46.5 to 60.1 mm were selected for treatment. However, only one pair was successfully observed spawning activity completely. Spawning takes place between morning and noon in three spawning periods. In each period, spawning lasts between 8 and 11 days. Between spawning periods takes 14 to 22 days. After fertilization, the eggs are attached with filaments to the spawning substrate and placed at a depth of 7.3-24.3 cm from the surface of the water. One group of eggs spawned consists of 78-116 eggs with a diameter range between 1.05 and 136 mm. The eggs hatch in a period of 4 to 10 days. The body length of the newly hatched larvae ranges from 4.13-4.40 mm and will reach a size of 7.85 mm with a survival rate of 48.1% after 41 days. The results of this study found several advantages from the characteristics of spawning and growth in the early stages that are useful for captive breeding efforts and reintroduction of this rainbowfish to their natural habitat. Thus, its population in the Prafi River system can be maintained.]]>

<![CDATA[Macrobenthic fauna is often used as a bioindicator of environmental quality. However, information about the environmental characteristics and the existence of macrobenthic fauna in the mangrove reforestation area is still very limited. The study of the profile of the Seribu Island mangrove reforestation area based on the characteristics of the macrobenthic environment and fauna was carried out in March 2014. The aim of this study is to determine the ecological conditions of the waters around the Seribu Island mangrove reforestation area. To find out the relationship between environmental characteristics and macrobenthic fauna with observation stations carried out by statistics on Correspondence Analysis (CA), while the environmental characteristics that determine macrobenthic fauna and their relationships are carried out with Principal Component Analysis (PCA) statistics and simple linear regression. The results of the study show that the concentration of measured environmental characteristics is not very different between stations and does not exceed the quality standard threshold for marine life. Then the macrobenthic fauna found consisted of 6 species with the highest density at Station 3 (05.00 ind/m2) and the lowest at Station 1 (02.00 ind/m2). At Station 1 the pH and temperature concentration is very high, while Station 2 and 3 have high salinity concentrations. Macrobenthic fauna Atilia (Columbella) scripta, Metopograpsus latifrons, Littoraria scabra, Saccostrea cucculata, and Cardisoma carnifex can be associated with mangroves at all stations. In addition, the environmental characteristics that determine the presence of C. carnifex macrobenthic fauna are pH parameters, where the higher the pH concentration, the lower the density of C. carnifex. Then the environmental characteristics that determine the presence of the macrobenthic fauna of S. cucculata, M. latifrons and A. scripta are determined by DO (Dissolved Oxygen) and salinity parameters namely the lower DO (Dissolved Oxygen) concentration and salinity, the higher the density of S. cucculata, M. latifrons and A. scripta.]]>
