Abstract

Sharks are predatory animals that dwell near coral reefs and swim at the ocean's bottom. Since the inclusion of many shark species in CITES Appendix II status in 2013, shark groups have become a global issue. This is owing to shark fishing's high exploitation, both as a target capture and as bycatch. It is divided into eleven fisheries management areas, one of which is WPPNRI 572, according to the Regulation of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number 18/PERMEN-KP/2014 concerning the State Fisheries Management Area of the Republic of Indonesia, hereinafter abbreviated as WPPNRI. The Indian Ocean waters west of Sumatra, as well as the Sunda Strait, are included in this area. Because it faces the high seas, notably the Indian Ocean, Sumatra's west coast is a key area of the Indonesian sea. The city of Sibolga is strategically important as one of the key entry points for utilizing the potential of western Sumatra's waters. This study was place during August and September of 2021. The goal of this study was to identify sharks landed through TPI Sibolga City in North Sumatra Province, describe their morphology and morphometrics, and describe their conservation status using IUCN and CITES criteria. Squalus chloroculus, Nebrius ferrugineus, Carcharhinus brevipinna, Carcharhinus falciformis, Carcharhinus melanopterus, Carcharhinus sorrah, Rhizoprionodon acutus, Rhizoprionodon oligolinx, and Sphyrna lewini were among the 310 sharks successfully landed in the TPI, according to the study's findings. The overall length variable has the strongest tendency, according to the results of the Principal Component Analysis Scree Plot. C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus are shark species with comparable morphometric features. According to the IUCN, the conservation status of S. lewini is Critical or Threatened (EN). The status of N. ferrugineus is Very Vulnerable (VU). Near Threatened (NT) status for S. chloroculus, C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus. Less Worrying Status was assigned to R. acutus and R. oligolinx (LC). While the trading status of sharks based on CITES, particularly C. falciformis, C. melanopterus, and S. lewini, are included in the Appendix II list, which denotes species that are not threatened with extinction but could be affected if trade continues without regulation.

Abstract

This study aims to analyze the types and abundance of microplastics in mussels (Glauconome virens) and differences in the abundance of microplastics between research stations in the coastal waters of Tanah Merah Village, Meranti Islands. Samples were taken from three different locations: residential areas, fishing ports, and mangrove areas. The number of mussel samples from the three stations was 54 individuals, with three size groups. Water quality parameters such as temperature, salinity, pH, and current speed were measured to determine the condition of the aquatic environment. Microplastics were analyzed using a microscope after going through a process of dissolving the mussel meat with a 10% KOH solution. The results showed that three types of microplastics were found, namely fiber, fragments, and films, with an average value of 46.50 particles/ind. Fiber type was the highest type found, followed by fragments and films. The highest abundance of microplastics was found in the mangrove area with an average value of 54.11 particles/ind, while the lowest was in the fishing port with 37.61 particles/ind. The abundance of microplastics in mussels showed significant differences (p<0.05) within the station. Possible causes of the difference were discussed

Abstract

Global climate change caused by increasing atmospheric CO₂ emissions threatens coastal ecosystems, including mangrove forests that function as carbon sinks. Kedabu Rapat Village in Meranti Islands Regency has implemented a mangrove rehabilitation program since 2017 to overcome coastal abrasion and restore the ecosystem. This study examines mangrove density, organic carbon stock in sediment, the relationship between density and carbon stock, and variations in carbon stock between sediment depths. The study was conducted at three stations according to the year of rehabilitation using a survey method with sediment sampling as deep as 30 cm, Organic carbon was analyzed using the LOI method. The study's results identified one mangrove species, Avicennia alba, from the Acanthaceae family, which dominated all observation stations. Vegetation density is classified as very dense, averaging 7,911 ind/ha, with the highest density at Station 1 (8,935 ind/ha). All stations' average sediment carbon stock reached 117.23 tons/ha, with the highest value at Station 3 (135.19 tons/ha) and the lowest at Station 1 (96.97 tons/ha). Statistical analysis revealed a weak correlation (r = 0.218; p > 0.05) between mangrove density and sediment carbon stock, indicating that other environmental factors, such as sedimentation and sediment input, play a more significant role. The distribution of carbon stock by depth was relatively uniform, ranging from 38.25 to 40.58 tons/ha. These results indicate that external factors are also determinants of carbon absorption rates

Abstract

Plastics in the environment would eventually be degraded into plastic granules which are called microplastics. In recent years, microplastics have been spread widely not only inland but also in aquatic habitats, where averagely 5% of the plastic produced each year will end up in marine waters. The purpose of this study which was conducted in October to November 2020 was to identify the type and abundance of microplastics in the sediment as well as its possible relationship with the sediment organic matter in Dumai waters. Sediment samples were taken from Dumai coastal waters by using purposive sampling method. Identification of the types and abundance of microplastics as well as the analysis of sediment organic content were carried out in the Laboratory of Chemical Oceanography, Department of Marine Sciences, Universitas Riau. Microplastic and sediment particles were separated using 150 ml saturated NaCl solution. The types of microplastics found are fiber, fragment and films, where fiber was found to be the most commonly found (36.43%), followed by fragments (31.97%) and films (31.60%), respectively. No significant correlation found between microplastic abundance and the sediment organic content in Dumai coastal waters.

Abstract

High anthropogenic activities on the east coast of Karimun Besar Island contribute a certain amount of wastes, especially plastics. Plastics will be degraded due to the natural mechanism of smaller parts and known as microplastics. Small size and widespread distribution has caused microplastics can be found widely in the ocean and coastal areas. This study was conducted in March 2020, located on the east coast of Karimun Besar Island, Province of Riau Islands. The purpose of this study was to know the presence of microplastics in its coastal water. The method used in this study was a survey method by taking samples from four stations with suspected different anthropogenic activities. The results showed that the lowest abundance of microplastics in the coastal waters of the east coast of Karimun Besar Island was 63,33 particles/m3 and the highest was 161,66 particles/m3, with the dominant type found was fibre. The abundance of the microplastic between station was found to be significantly different (p < 0,05).
