Abstract

Environmental degradation has occurred in various ecosystems in the world. This  also carries out in the sea and even sometimes threaten human life, whether directly or indirectly. Likewise, events in the marine environment associated with poisoning, caused by toxic algae such as dinoflagellates. To see the progress the survey research was conducted on Thallasia sp to see the growth of toxic dinoflagellates Gambierdiscus, Ostreopsis and Prorocentrum in the Nirwana Coast Padang. The data analysis uses two-way statistics with Turkey's Advanced Test. The results showed that Gambierdiscus and Ostreopsis almost the same number and were still low. High striking results occurred on Prorocentrum which differed markedly from both Gambierdiscus and Ostreopsis. This results also significantly different among stations.

Abstract

The Chaetodontidae family fish is an indicator species because it has a close relationship with coral reefs based on a strong preference for coral stone as the main component of coral reefs. The existence of these fish can be used as a guide to assess and monitor the condition of coral reefs. This study was conducted in March 2022. The purpose of this study was to determine the abundance of reef fish of the Chaetodontidae family in the waters of Talam Island, to determine the condition of life coral cover and the relationship between the abundance of the Chaetodontidae family and coral cover. The method used in this study is a survey method. Data collection on reef fish of chaetodontidae family was carried out using the Underwater Visual Census (UVC) method and coral reefs condition data collection was done using the Line Intercept Transect (LIT) method. The results showed that the abundance of Chaetodontidae ranged from 710 to 1,430 individuals/ha with an average of 1,110 individuals/ha. The highest abundance of 1,430 individuals/ha at station III with a depth of 6 meters, while the lowest abundance was station II with a depth of 8 meters which was 710 individuals/ha. The percentage of life coral cover at each station ranged from 47.70% - 56.98%, 42.60% - 54.40% and 56.68% - 69.08%. Based on these percentages, the average percentage of life coral cover is 54.74% (good category), and there is a very strong relationship between life coral cover and the abundance of the Chaetodontidae family.

Abstract

Mangrove is a type of vegetation that grows on muddy soil in tidal areas, around the river estuary, and in tropical coastal areas. To support the success of mangrove forest management, it is important to pay attention to the factors that affect the growth of mangroves. This research was conducted in October – December 2021. The purpose of the study was to determine the type, density value, frequency, and cover of mangrove vegetation and its importance value index in Pongkar Village, Karimun Regency, Kepulauan Riau Province, using survey methods and sampling and measuring environmental quality parameters waters in the field. Based on the result of the research, the types of mangrove vegetation found consisted of 6 species, namely Avicennia alba, Avicennia marina, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Lumnitzera littorea.

Abstract

This research was carried out in July - August 2022. The location of coral sampling is in the coral reefs of the Nirwana coast, West Sumatra. The objective by conducting this study is to determine the type of nematocysts in the body tissues of corals scleractinia, Acropora formosa, Seriatopora sp, and Pocillopora damicornis. Method to know the types of nematocysts from A. formosa, Seriatopora sp, and P. damicornis were carried out using an Olympus, microscope with x100 objective lens magnification at the Marine Biology Laboratory, Faculty of Fisheries and Marine Science, University of Riau. Of the 25 major types of nematocysts known in the phylum Cnidarian, two types are found in these three species. The results showed that there were two main types of nematocysts, namely holotrichous isorhizas (HI) and micro basic p-mastigophore (MpM). The three coral species, A. formosa, Seriatopora sp, and P. damicornis, of the holotrichous isorhizas (HI) nematocysts type and the micro basic p-mastigophore (MpM) nematocyst, were found in the coral species A. formosa and P. damicornis. The type of nematocyst is thought to be used to attack and kill prey.
