Abstract. Research on the sponge barnacle of Indonesia is very rare, and this study is aimed to describe the morphological characteristics of sponge barnacles and their specific relationship with their sponge host species. This research was a survey and sponge samples were collected by tearing apart any available sponge found in three sampling locations, typically coral reef areas of Weh Island, Seribu Islands, and Karimunjawa Islands. Sponge barnacles contained in sponge samples were observed using stereo microscope and scanning electron microscope, and species identification was determined based on the morphological description of Darwin (1854), Pilsbry (1916), Martin dan Davis (2001), and Kolbasov (1993). Four species of sponge barnacles were found consisting of Acasta cyathus, Acasta fenestrata, Euacasta dofleini, and Membranobalanus longirostrum. Specific relationships of barnacle and its sponge host were found between Euacasta dofleini and Haliclona sp. and between Membranobalanus longirostrum and Suberites sp. respectively.

Abstract

The grey-eel catfish is a highly valued fish species in some parts of Indonesia. The fish is common in brackish water of estuaries, marine and freshwater habitat. They are not are not usually catched in commercial scale because of the limited population in its habitat. Although the status is not evaluated, the fish is predicted facing extinction in several countries. We conducted a study to examine the biological information and reproductive biology of the fish in Kota Langsa to gather information that can be utilize to evaluate reproductive status of the fish in several habitats. Parameters tested in the study includes sex ratio, length-weight relationships, candition factor, size at first maturity fecundity and reproductive potential of the fish. Research results provide information that the fish follows negative allometric model with constant condition factor throughout the study. The catches were relatively young fish which have not reached maturity stage. Fishes in the class sized at 510-550 mm provide the largest contribution to total eggs production. To ensure sustainability of the fish it is advised that the fish must catched at size larger than 550 mm.

The coastal region is a meeting point of land and sea. The coastal area utilization has developed intensively, which causes the sustainability or capacity of coastal ecosystems, and the pollution potential in this area exceeded due to various human activities. This condition affects the existence of microalgae, which play an important role not only in the food chain in the aquatic environment but also in humans at the end. This research was carried out in Sendang Biru Waters, South Malang Regency. The purpose of this study was to map and determine the biodiversity as well as the distribution of microalgae in coastal waters using in situ data. The data were analyzed using geographic information system techniques in the form of microalgae distribution and biodiversity maps. The results showed that the microalgae identified from the genera Chaetoceros and Navicula showing the highest frequency. The biodiversity index value at station 1 was 3,312, at station 2 was 3,184. These values indicate that the Sendang Biru waters were highly diverse in microalgae composition. The results of the temperature-water quality parameters are 27-29 ° C, salinity 32-35 ppt, and pH 7.8-8.2. The range of nitrate nutrients ranges from 0.0142 to 0.082 mg/l, while phosphate from 0.024 to 0.074 mg/l, silica showed values between 1.249 to 1.393 mg/l. Based on the analysis of chlorophyll-a, the range of chlorophyll-a values was between 1.773-1.777 mg/l. All parameters of water quality were classified as suitable for microalgae growth. Therefore, the microalgae biodiversity in this location can still be considered relatively high.Keywords:Coastal AreaBiodiversityMicroalgaeABSTRAKWilayah pesisir merupakan tempat bertemunya daratan dan lautan.

Abstract

The interaction between algae and coral is one of the most important of ecological processes in coral reef ecosystems. They are one of the main food sources in a large number of herbivorous animals in coral reef ecosystems. Makroalgae is also a major competitor in degrading coral reefs at a time when macroalgae gains dominate the coral reefs. Algae growth is relatively very fast, so it can be used as an indicator in the initial study to determine the processes that affect populations and coral reef communities. The purpose of this study is to determine the distribution of macroalgae cover on coral reefs in the Nusa Penida, Bali using the transect quadrant (1x1m2)x 100m method. This study shows that the lowest macroalgae cover at Crystal Bay and the highest in Buyuk can be concluded that the high macroalgae cover is made possible by the large supply of nutrients from the land which becomes the supplier of organic materials that increases the fertility of waters, meanwhile in the waters close to the high seas obtain additional nutrients derived from the lifting of the water mass (upwelling). Data and information are needed for the interest of regional planning towards the future related to the management and utilization of marine resources potential in the coastal area in Nusa Penida, Bali.Interaksi antara alga dan karang merupakan hal terpenting dari proses ekologi pada ekosistem terumbu karang. Mereka merupakan salah satu sumber produsen primer pada sejumlah besar hewan herbivora pada ekosistem terumbu karang. Makroalga juga menjadi pesaing utama dalam mendegradasi terumbu karang pada saat kelimpahaan makroalga mendominasi terhadap terumbu karang. Pertumbuhan alga tergolong sangat cepat, sehingga dapat digunakan sebagai indikator dalam studi awal untuk mengetahui proses yang mempengaruhi populasi dan komunitas terumbu karang. Tujuan dari penelitian ini adalah mengetahui sebaran tutupan makroalga pada terumbu karang di daerah utama wisata penyelaman Nusa Penida, Bali dengan menggunakan metode transek kuadran dengan ukuran (1x1m2) x 100 m. Penelitian ini menunjukan bahwa tutupan makroalga terendah pada Crystal Bay dan tertinggi di Buyuk dapat ditarik kesimpulan jika tingginya tutupan makroalga dimungkinkan oleh besarnya suplai nutrien daratan yang menjadi pensuplai bahan organik yang meningkatkan kesuburan perairan. Sedangkan pada  perairan yang dekat dengan laut lepas mendapat tambahan nutrien yang berasal dari pengangkatan massa air (upwelling). Data dan informasi ini diperlukan untuk kepentingan perencanaan pengembangan wilayah ke depannya yang terkait dengan pengelolaan dan pemanfaatan potensi sumberdaya laut di wilayah pesisir di Nusa Penida, Bali.

Abstract

 Singkil Swamp Wildlife Reserve is a peat swamp ecosystem located in Aceh Singkil Regency, Aceh Province. Peat swamp ecosystem has an important function in protecting and balancing water systems, carbon stocks and biodiversity conservation. However, information on the characteristics of the waters of this ecosystem is still not widely known, especially in the area of utilization that is influenced by community activities. This study aims to determine the aquatic environmental characteristics of the Singkil Swamp Wildlife Reserve utilization area covering the physical and chemical parameters of the water and the relationship among those parameters. Sampling was carried out through field observations both in-situ and ex-situ at 5 stations for 3 months (April-June 2021). Observations were made on water quality parameters namely temperature, transparency, depth, current, colour, salinity, water smell, pH, DO, TDS, TSS, conductivity, phosphate and nitrate. Analysis of the data was conducted, namely correlation analysis, PCA (Principal Component Analysis) and CA (Cluster Analysis). The water color was black and the pH was acidic, that is a characteristic of the swamp waters. The results of the measurement of water quality parameters indicate that TDS (13-44 mg/l), TSS (9-236 mg/l), total phosphate (0.01-2.14 mg/l), and nitrate (0.5-25.7 mg/l) were suitable for freshwater aquaculture to support fishery reserve. Based on the clustering of those stations, 5 observation stations were grouped into two different groups, namely cluster 1 with the number of observation stations of 2 stations (Stations 1 and 2) and cluster 2 with the number of observation stations of 3 stations (3, 4 and 5). The parameter values of total phosphate, pH, DO, and nitrate in cluster 1 tend were higher than in cluster 2.Keywords:Peat swampFreshwaterWater quality
