Abstract

The purposes of the reasearch that was conducted on July 2022 are to determine the biodiversity, composition, density, community index, correlation and contribution of gastropods on 18 year post tsunami and 16 year coastal rehabilitation in research observation of Banda Aceh. The method used is purposive sampling with 4 observation stations. Gastropods were collected using a quadratic transect perpendicular to the shoreline. PCA analysis was carried out to determine the level of contribution of gastropod species based on observation stations, while SIMPER and CA analyzes were carried out to compare and classify gastropod communities. A total of 8 families, 8 genera, 10 species and 6945 ind gastropods were found with densities ranging from 37.55 – 136.60 ind/m2. The highest diversity index was found at Station II (0.63), the highest uniformity index was found at Station III (0.86) and the highest dominance index was found at Station I (0.99). Gastropods Nerita planospira, Cassidula aurisfelis, C. nucleus, Sphaerassiminea miniata and Oncidium sp. closely related to Rhizophora mucronata and Avicennia alba growing on muddy substrates, while Morula iostoma, Cerithidea cingulata, Littoraria melanostoma, Nassarius olivaceus and L. scabra were closely related to R. mucronata growing on sandy mud substrates. Furthermore, C. cingulata species contributed at Stations I and IV, while C. aurisfelis species contributed at Stations II and III.  Kajian dilakukan pada bulan Juli 2022 yang bertujuan untuk mengetahui biodiversitas, komposisi, kepadatan, indeks komunitas serta keterkaitan dan kontribusi gastropoda terhadap stasiun pengamatan pasca 18 tahun tsunami dan 16 tahun rehabilitasi pantai di Kota Banda Aceh.

Abstract

Microplastic contamination in marine environments is a growing concern, particularly in fish species consumed by humans. This study investigates the presence and characteristics of microplastics in the livers of Indian mackerel (Rastrelliger kanagurta) and yellowtail scad (Atule mate) collected from Pahang and Kelantan. The abundance of microplastics was quantified for each species at each location, with the total count normalized by the number of fish analyzed following the extraction and identification process. Microplastic identification was conducted using a Stereoscopic Microscope, while polymer composition was determined through ATR-FTIR spectroscopy. The microplastic abundance recorded was 0.067 particles per fish. The microplastic identified were predominantly fragments and filaments in red, black, and grey colors. The polymers found were poly(diallyl phthalate) (PDAP), poly(butylene terephthalate) (PBT), polypropylene (PP), poly(cyclohexylenedimethylene terephthalate) (PCT), and high-density polyethylene (HDPE). The finding of microplastics in fish livers provides preliminary evidence of contamination and suggests direct exposure of these vital organs. This raises serious concerns about potential contamination in other crucial organs, including the gills, gastrointestinal tract, tissues, and even the brain. This highlights the need for further research on microplastic exposure pathways and its ecological implications along the east coast of Peninsular Malaysia.

Abstract

The most crucial aspect of managing an ecosystem or habitat is knowledge about accompanying biota, such as snails. The research on mangrove snails in the KPH Region III Aceh City of Langsa area was conducted in November 2021 with the goal of evaluating species diversity, density, ecological index, distribution, and their link to surrounding environmental conditions. Snail data was obtained via quadrat transects, with observation stations established using purposive sampling.The snail diversity was found to be five species from four families, with the highest density found in N. planospira (03.13 ind/m2). The diversity index was low (H' ‰¤ 2.0), dominance was moderate (0.5 < C ‰¤ 0.75), and uniformity tended to be balanced (0.5 < E ‰¤ 0.75). The distribution pattern is clustered (Iδ> 1), with C. cingulata being abundant (83.33%), and C. capucinus being frequently found (50.00%), N. planospiraonly found occasionally (36.11%), and L. scabra and T. telescopium are relatively uncommon (11.11% and 0.56%, respectively), with a link to environmental variables indicating that T. telescopium prefers fine mud substrates. Meanwhile, C. cingulata, C. capucinus, L. scabra, and N. planospiralive in habitats with fine mud substrates that are more solid than T. telescopiums habitats.

Abstract

The study was conducted between August and September of 2021 in order to determine the density, ecological index, distribution pattern, geographic distribution, environmental factors, and the relationship between hermit crabs and environmental factors. Hermit crabs were gathered using a quadratic transect and sample plots, while environmental variables were measured in situ. PCA and CCA multivariate statistics were used to determine the characteristics and correlation between hermit crabs and environmental factors. Hermit crabs were discovered to be comprised of two species (Clibanariuslongitarsus and C. infraspinatus) and one family (Diogenidae), with the highest density found in the C. longitarsus species (1.22 ± 0.57 - 4.68 3.53 ind/m2), diversity index is categorized as moderate (2.0<H‰¤3.0), the dominance is low (0<C‰¤0.5), the distribution pattern is clustered (Iδ>1), the geographical distribution is abundant (>80%), and environmental factors are categorized as good. In addition, Stations I and II have high DO, TOM, mangrove density, C. longitarsus, and C. infraspinatus parameters, whereas Station III has high salinity, pH, and temperature, with salinity, mangrove density, and TOM being the most influential parameters on hermit crab density.

Abstract

Water quality is one of several aspects that affect the success of aquaculture business. This study analyzes water quality and assesses its impact on aquaculture enterprises in the Rancong pond region of Lhokseumawe City. The study ran from November to December 2018. The water quality of the Rancong pond was sampled directly and tested in multiple labs. The field survey and purposive sampling strategy separated the research location into four stations with three water sampling points. Temperature, salinity, turbidity, brightness, pH, dissolved oxygen, alkalinity, total organic matter, BOD5, total ammonia nitrogen, nitrite, nitrate, phosphate, lead (Pb), total Vibrio bacteria, total general bacteria, and phytoplankton types and abundance were measured. The suitability of water quality is assessed using descriptive analysis, scoring, and matching. The investigation indicates that the quality and maintenance of the source water are highly suitable (S1). Traditional vannamei shrimp ponds in Rancong, Lhokseumawe City, should be maintained as fisheries cultivation areas.

Abstract

Tropical marine environments are abundant and diverse; therefore, shark and ray research at fishing port PPS Lampulo, Banda Aceh City was carried out focusing on morphometric characteristics and differences based on multivariate analysis in July 2020 to identify sharks and rays that landed at fishing port PPS Lampulo, Banda Aceh City and determine their primary characteristics. The shark and ray samples used were from the Indian Ocean and the Malacca Strait and measured total length (TL), fork length (FL), and standard length (SL) for sharks and disc width (DW), TL, and disc length (DL) for rays. Principal component analysis (PCA) and discriminant analysis (DA) were performed on the morphometric data. The PCA analysis revealed that sharks and rays caught in Pelabuhan Perikanan Samudera (PPS) Lampulo, Banda Aceh City, can be divided into two distinct groups. The first group of sharks consists of species with large FL and SL morphometrics, namely P. kamoharai, C. plumbeus, P. glauca, and A. superciliosus. The second group of sharks consists of species with large TL morphometrics, specifically A. pelagicus and C. plumbeus. For the ray group, the first group comprises species with large TL and DW morphometrics, represented by A. ocellatus. The second group of rays consists of species with large DL morphometrics, namely P. sephen and H. jenkinsii. The results of DA revealed distinct differences in the size of sharks caught in the Indian Ocean and the Strait of Malacca, specifically in PPS Lampulo, Banda Aceh City. However, no significant differences in size were observed for the rays, regardless of whether their size was measured using DW, TL, or DL.

Abstract

The increasing use of mercury in the industrial sector poses significant risks to freshwater ecosystems and aquatic organisms. Milkfish (Chanos chanos), a widely consumed species, is now being reared in freshwater environments, raising concerns about mercury bioaccumulation and food safety. This study aimed to determine the median lethal mercury concentration for milkfish at 96 hours (LC50) in freshwater using an experimental approach and probit analysis. Five mercury concentrations were tested: 0 (control), 0 .110 mg Hg/L, 0.195 mg Hg/L, 0.347 mg Hg/L, and 0.618 mg Hg/L. The results indicated that mercury is highly toxic to milkfish, with a 96-hour LC50 of 0.147 mg Hg/L. Clinical symptoms observed included loss of reflex movements, irregular swimming, frequent surfacing with widened mouth and operculum openings, convulsions, and ventilation of the ram before mortality. These findings highlight the acute toxicity of mercury in freshwater milkfish and underscore the potential health risks associated with mercury contamination in aquaculture systems.

Abstract

Microplastics, as physical pollutants, have become a hazard and can accumulate in fish tissues. There is limited documentation of the spread of microplastic buildup in fish flesh. The purpose of this research was to investigate the distribution of microplastics in fish flesh. This study used the golden threadfin bream (Nemipterus virgatus) as one of the commercial marine fish in peninsular Malaysia. The fish was dissected by filleting and separated through its dorsal, ventral, and caudal parts to observe if there was variation in the accumulation of microplastics in each part of the fish flesh. The findings show that the caudal part has the most microplastic accumulation compared to the dorsal and ventral parts. However, there is no significant difference in the amount of microplastic discovered in any part of the fish based on statistical analysis. The bulk of the microplastics identified are black and have a fibre form. Polyamide (PA), polyethylene terephthalate (PET), and polypropylene are types of microplastics found in the fish flesh. This research shows that microplastics can accumulate in every part of the fish flesh in varying amounts. To accurately depict the average number of microplastics in fish flesh, it is recommended to randomly sample the fish flesh for detection.

Abstract

The structure of the plant community significantly influences the equilibrium of the surrounding environment, affecting the trophic interactions within its ecosystem. The investigation of mangrove vegetation in Cut Mamplam village was carried out in September 2021 to determine the condition and structural characteristics of the mangrove ecosystem by multivariate analysis. The mangrove vegetation in Cut Mamplam Village was sampled at three observation stations by establishing a transect parallel to the coast. Subsequently, the community structure was examined and assessed using cluster analysis and nonmetric multidimensional scaling using the PRIMER v7 software. The study findings indicate that the mangrove forest vegetation in Cut Mamplam Village consists of five species from three families. Avicennia alba, A. lanata, Bruguiera gymnorrhiza, Rhizophora mucronata and Sonneratia alba. The highest density of mangrove vegetation was observed in A. alba in all categories: trees (616.67 ind/ha), seedlings (833.33 ind/ha) and saplings (66666.67 ind/ha). Additionally, the highest important value index (IVI) was recorded in A. alba for all categories: trees (232.16%), seedlings (102.40%), and saplings (228.43%). A similarity of mangrove density between species was noted at 60%, resulting in the formation of two distinct groups. Regarding the basal area, the vegetation stands of A. alba and A. lanata exhibited the highest values (280.61 and 266.03 m2/ha, respectively). The similarity of basal area among the observed species was 20%, resulting in the formation of two distinct groups. Additionally, Station II, classified as having mature vegetation, demonstrated a maturity similarity of 80% between observation stations.
