Publisher : Universitas Riau

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.

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.

The purpose of community service activities carried out is to provide knowledge and technology about Hemibagrus nemurus fish hatchery technology through artificial spawning at the Independent Sawah Fishery Group in Sawah Village, North Kampar District, Kampar Regency. The method applied in this community service activity is the lecture method, discussion and field practice. The lecture method was carried out in the meeting room of the Chairperson of the Independent Sawah Fishery Group, Sawah Village, North Kampar District, Kampar Regency by providing material about the hatchery of H. nemurus fish through artificial spawning. The results of the evaluation of changes in knowledge carried out on 11 participants of the activity showed that 8 people (72.73%) had been able to absorb the material given with a very good predicate, 2 people (18.18%) could absorb the material given with a good predicate, 1 people (9.09%) could absorb the material with sufficient predicate, while those who received less predicate and less predicate were not found. The results of the skills evaluation show that members of the Independent Sawah Fishery Group have been able to directly practice the activities that have been given in the field regarding H. nemurus fish hatchery technology. Meanwhile, the results of the impact evaluation show that members of the Sawah Mandiri Fishery Group have started to hatch H. nemurus fish in addition to the catfish hatchery that has been done so far.

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.
