“…In contrast, this study showed that carnivorous abundance in presence of mangroves was lower than in absence of mangroves. Moreover, a lower abundance of lutjanid in this area supports a previous study by (Ulumuddin et al 2021), that shows decreasing biomass of lutjanid fish as it was farther from the mangrove's habitat. The presence of mangroves habitat in the coral reef areas affected the abundance of reef fish due to the fact that the mangroves give shelter, particularly to herbivorous fish.…”

“…The positive effect of the mangrove habitat showed in herbivore fish, while the contrast result showed in the carnivore abundance. A similar result showed by Ulumuddin et al (2021), who showed a decreased pattern of carnivore abundance as it was farther away from the mangrove habitat. Reef fishes tend to use mangrove habitats for temporary shelter when high-pressure presence in their natural habitat (reef) and a place for foraging (Mumby et al 2004).…”

“…However, there are mangrove areas that are far from coral habitats. At the same time, the presence of reef fish was closely related to the mangrove ecosystem, so it is vital to know the relationship between mangrove characteristics, distance, and the influence of waters on the presence of reef fish Ulumuddin et al 2021). Many economically important reef fish are reported to spend part of their life cycles in estuaries as juveniles before migrating to offshore populations as adults Berkström et al 2013;Olds et al 2013;Igulu et al 2014;Martin et al 2015;Whitfield 2017;Bradley et al 2019).…”

Abstract. Utama RS, Renyaan J, Nurdiansah D, Makatipu PC, Suyadi, Hapsari BW, Martha E, Rahayu EMD, Sugiharto A. Akbar N. 2022. Diversity of reef fish species in presence of mangrove habitat in Ternate, North Maluku, Indonesia. Biodiversitas 23: 5184-5193. Research on reef fish has been widely reported, where information about reef fish communities is an important factor for evaluating fisheries management and coral reef management. Mangroves as the nursery, foraging, and growing areas were also important to assure sustainable reef fish fisheries. This paper studies reef fish abundance and diversity in Ternate Waters in the presence of mangrove in coral reef habitats. To determines coral reef condition underwater photo transect was performed while an underwater visual census (UVC) was used to determine the abundance and diversity of reef fishes in Ternate waters between 2017 and 2018. A total of 14 stations were used, with eight stations near the mangroves and six stations that did not contain mangroves. Based on the observation, fish species richness in mangrove absence was higher than in the presence of mangroves, with 68 and 65 species in 2017 and 66 and 62 species in 2018. However, the abundance of reef fish was recorded high in the presence of mangroves than in the absence of mangroves, with 390 and 289 individual differences in 2017 and 2018. Mangroves' complexity affected part of reef fish communities in Ternate water, particularly Lutjanidae, Serranidae, and Scaridae, which might influence the abundance of reef fishes rather than the species richness. In addition, carnivore shows a negative effect in the presence of mangroves, in contrast with herbivores. It is related to mangrove functioning as a temporary shelter when high-pressure presence in their natural habitat (reef) and a place for foraging. Therefore, mangrove management must be a consideration in the coral reef or fisheries management program.

“…Skala ruang bentang laut juga bisa berukuran kecil dengan radius beberapa kilometer saja. Radius pengamatan merupakan luas bentang laut yang dibatasi oleh area jelajah ikan karang (homerange) dan kondisi struktur bentang laut (seascape) yang berada di area penelitian (Pittman, 2018;Ulumuddin et al, 2021). Area jelajah ikan (home range) menjadi pembatas radius pengamatan dikarenakan kemampuan mobilitas masingmasing ikan berbeda, sehingga hal tersebut dapat menjadi acuan dalam mengetahui kelimpahan ikan pada area pengamatan.…”

Ikan karang selama hidupnya dapat mendiami satu habitat saja atau melakukan migrasi ke ekosistem di sekitarnya. Faktor tersebut membuat terjadinya interaksi antara ikan karang dengan ekosistem mangrove dan terumbu karang. Pendekatan bentang laut (seascape ecology) masih belum banyak dilakukan mengingat pendekatan ini penting untuk mengetahui kelimpahan ikan yang berada di sekitar area terumbu karang, sehingga dapat dijadikan sebagai pedoman dalam pengelolaan kawasan pesisir. Oleh karena itu penelitian ini bertujuan untuk mengetahui struktur bentang laut (seascape), interaksinya dengan ikan karang, dan menilai tingkat konektivitas dari keduanya di Raja Ampat dan Maluku Tenggara. Metode penelitian yang digunakan yaitu pengolahan dan analisis data spasial dan statistika menggunakan software QGIS 3.14 dan RStudio versi 2.0.4. Hasil penelitian dari analisis data statistika menggunakan analisis korelasi dan regresi diperoleh bahwa kelimpahan Ikan Lutjanidae pada Pulau Kei Kecil, Maluku Tenggara memiliki konektivitas dengan nilai regresi tertinggi yang dijelaskan oleh metrik Distance to Mangrove (DistM) dengan nilai koefisien korelasi sebesar -0,88; R2 0,7777; dan nilai AIC (Akaike Information Criterion) 18,01. Berdasarkan hasil penelitian, kesimpulan yang diperoleh adalah matriks Distance to Mangrove (DistM) menjadi matriks yang memiliki hubungan erat dengan Ikan Lutjanidae yang dapat mempengaruhi kelimpahan Ikan Lutjanidae di lokasi penelitian. Reef fish, during their lifetime, can inhabit only one habitat or migrate to the surrounding ecosystem. These factors make the interaction between reef fish with mangrove ecosystems and coral reefs. However, the seascape ecology approach is still not widely used, considering that it is important to determine the abundance of fish around coral reef areas, so that it can be used as a guideline in the management of coastal areas. Therefore, this study aims to determine the structure of the seascape, its interaction with reef fish, and assess the level of connectivity of both in Raja Ampat and Southeast Maluku. The research method used is the processing and analysis of spatial and statistical data using software QGIS 3.14 and RStudio 2.0.4. The results of statistical data analysis using correlation and regression analysis showed that the abundance of Lutjanidae on Kei Kecil Island, Southeast Maluku had connectivity with the highest regression value described by the Distance to Mangrove (DistM) metric and has a correlation coefficient value of -0.88; R2 0.7777; and the AIC (Akaike Information Criterion) score of 18,01112. Based on the results of the study, the conclusion obtained is that the Distance to Mangrove (DistM) metric is a metric that has a close relationship with Lutjanidae fish which can affect the abundance of Lutjanidae fish in the research location.

“…In the context of the Indonesia archipelago, the salt marsh ecosystem does not exist significantly. In contrast, mangrove, seagrass, and coral reef ecosystems are closely tied and densely concentrated throughout the Indonesian inter-island waters [58]. In this case, a holistic and seascape-wide approach is necessary to effectively conserve blue carbon ecosystems and their associated services [57].…”

Blue carbon ecosystems are key for successful global climate change mitigation; however, they are one of the most threatened ecosystems on Earth. Thus, this study mapped the climatic and human pressures on the blue carbon ecosystems in Indonesia using multi-source spatial datasets. Data on moderate resolution imaging spectroradiometer (MODIS) ocean color standard mapped images, VIIRS (visible, infrared imaging radiometer suite) boat detection (VBD), global artificial impervious area (GAIA), MODIS surface reflectance (MOD09GA), MODIS land surface temperature (MOD11A2), and MODIS vegetation indices (MOD13A2) were combined using remote sensing and spatial analysis techniques to identify potential stresses. La Niña and El Niño phenomena caused sea surface temperature deviations to reach −0.5 to +1.2 °C. In contrast, chlorophyll-a deviations reached 22,121 to +0.5 mg m−3. Regarding fishing activities, most areas were under exploitation and relatively sustained. Concerning land activities, mangrove deforestation occurred in 560.69 km2 of the area during 2007–2016, as confirmed by a decrease of 84.9% in risk-screening environmental indicators. Overall, the potential pressures on Indonesia’s blue carbon ecosystems are varied geographically. The framework of this study can be efficiently adopted to support coastal and small islands zonation planning, conservation prioritization, and marine fisheries enhancement.
