The presence of coral reef fishes, especially family Chaetodontidae is one of bioindicators to environment health condition of coral reef. Fish indicator research in Bunaken Island waters aims to find out the community structure, such as the composition, abundance, density, equality, diversity and dominance. Data collection was conducted at 5 (five) locations in the Bunaken Island Traditional Zone where there are 5 (five) observation points respectively, namely TP-1 Mandolin, TP-2 Alung Banua, TP-3 Sachiko, TP-4 Muka Kampung, and TP-5 Bunaken Timur. Data collection by underwater visual census (UVC) techniques using SCUBA. The results showed there were 23 species of indicator fish from family Chaetodontidae, total individuals number of each species in 5 research sites as many as 97 individuals. The highest fish density is 0.06 at TP-5 while the lowest value in TP-2 with density value 0.02. Through indicator fish community structure indicates that the coral reef quality conditions is stable indicated by diversity values (H') in all locations were moderate category and inversely proportional by low dominance values, high leveling values (E). The similarity rate (IS) of indicator fish species in all locations differs from each other indicating the condition of coral reefs in each location grows independently without being influenced by other locations.Keywords: Reef Fish, Coral Reef, Indicator Fish.

The diversity of crabs in the Malalayang One coast is thought to vary between research locations and limited information on biota that live on rocky, sandy and muddy coastal beaches. Sampling was carried out at low tide at night by capturing directly using a protected hand and for lighting with the help of a flashlight. The collected samples were taken to the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Sciences, UNSRAT to be identified and for diversity using the Shanon-winer mathematical formula. The results of crabs obtained at five coastal locations on the coast of Malalayang, Manado, with a total of 106 with 7 species, namely Metopograpsus latifrons, Sesarmops impressus, Ocypode kuhlii, Macrophthalmus mareotis depressus, Uca vocans dussumieri, Grapsus Longitarsis and Grapsus albolineatus.Keywords: Crab, Morphology, Diversity, Coastal Ecosystem.

The purpose of this study was to determine the composition of nematocysts in the body tissue of the coral fungia, C. vaugani. The location for the collection of C. vaugani colonies was on the coral reefs of the Malalayang coastal area, Manado. This research was carried out in September - December 2020. The observation of nematocysts of C. vaugani was carried out using an Olympus CX41 microscope with a magnification of x100 objective lens which connected to a computer monitor equipped with an optical view 7 application at the Fish Health Environment and Toxicology Laboratory, Faculty of Fisheries and Marine Science, UNSRAT. The present results showed that C. vaugani had a composition of nematocysts, namely type I microbasic p-mastigophore (MpM-I) of 40.00%, small type II microbasic p-mastigophore (sMpM-II) of 31.11%, small holotrichous isorhizas (sHI) of 24.44 %, large type II microbasic p-mastigophore (lMpM-II) of 2.22%, and large holotrichous isorhizas (IHI) of 2.22%. sMpM-II is the most dominant nematocyst type of C. vaugani and this type of nematocyst is thought to be used by coral for aggression and killing prey or predator if there is disturbance from the surrounding aquatic environment where the coral lives. Further research is recommended to study the types and morphology of nematocyst from various species of coral fungia, including C. vaugani to understand the differences in their types and dimension of the nematocyst.

Ascidia Eudistoma sp. produce bioactive compounds that can inhibit the growth of microorganisms. Ascidians are also known for their potential secondary metabolites in the biomedical world. This study aimed to obtain isolates of the ascidia symbiont Eudistoma sp., determine the antifungal activity against the test fungus Candida albicans, and determine the anti-UV activity of the symbiont Eudistoma sp. The ascidia symbiont fungus was extracted using maceration method with ethyl acetate solvent and tested for antifungal activity using the test fungus Candida albicans. The antifungal activity test results showed that the diameter of the AFBN 5b inhibition zone of 9 mm. The symbiont fungus can be said to have potential as an antifungal drug. Testing the anti-UV activity of fungi in symbiosis with ascidia Eudistoma sp. using a spectrophotometer showed that the extract sample of the ascida symbiont fungus could produce an absorption at UV-B (λ 290–320 nm) of 3.8 absorbance and when compared to UV-A (λ 370–400 nm) an absorption value of 0.38 was obtained and is still classified as moderate Keywords: Ascidia, Eudistoma sp., symbionts, Antifungal and Anti-UV

The information about mangrove forest community structure in Tapuang village has never been reported. The location of the mangrove forest in this village is near to the settlements. Three line transects with 50 m distance were laid perpendicular to the shore. In each line transect, 5 quadrants (10 x 10 m2) were established. The data were analyzed using several parameters density, frequency, dominance, important index value and diversity. This study found 5 mangrove species namely Avicennia marina, Sonneratia alba, Sonneratia ovata, Rhizophora stylosa and Nypa fruticans. Avicennia marina was the most species found in each transects and had the highest density, frequency, and dominance values. The highest important value index (INP) was found in Avicennia marina in transect 2 with a INP value 183.80. Mangrove species diversity index for tree category in each transect was low (H'≤1) ranges from 0.99.Key Words: Tapuang Village, Mangrove, Community Structure

Kappaphycus alvarezii is one species algae that is very widely developed in the tropical waters, especially in Indonesia. The potential in these waters may decrease due to heavy metal pollution that accumulates in algae and sediments. Analyzing the content of heavy metal arsenic (As), using the SNI 01-2896-1998 test method, namely the metal contamination test method in food. The results obtained from this study were samples of brown and green Kapapphycus alvarezii taken from week I-V detected containing heavy metal arsenic (As) ranging from 0.17 - 0.42 ppm for green algae and 0.12 - 0.37 ppm for brown algae. This As concentration does not exceed the maximum heavy metal limit, which is 1.0 ppm for the maximum limit for heavy metal contamination in food. The concentration of heavy metal in sediments is 1.12 ppm, not exceeding the quality standard in the Environmental Protection Agency (EPA), the maximum heavy metal limit for arsenic in sediment is below 10 mg/kg

Crab of the genus Uca is one type of crustacean that makes mangroves a habitat to carry out their life cycle in order to remain sustainable. The purpose of this research is to identify the first, the second is to calculate the abundance, species diversity, dominance, and the third is to know the state of the aquatic environment around pH, temperature, salinity and substrate. The method used is the cruising method and the quadratic line transect method. The method of roaming as far as 300 m. While the line transect method is carried out by drawing three transect lines along 28 m. The identification results in Meras waters found 6 species. Based on data analysis using the cruising method, the number of individuals in Meras waters is 383 individuals, while in Molas waters there are 210 individuals. Based on data analysis using the quadratic line transect method, the species abundance index in Meras waters is 6,767 ind/m2, while in Molas waters it is 4,533 ind/m2. The value of H' at two locations is moderate. The value of C in two locations is low. Keywords: Meras, Molas, Crabs, abundance, species diversity, dominance.
