Abstract

Studies related to the comparison of ectoparasites that infect snakehead from different habitats and their relationship to biometric conditions have not been widely studied. Thus, present study aimed to investigate the prevalence, intensity, dominance, and predilection of ectoparasites on snakehead collected from ditches, paddy fields, and swamps and correlate them with biometric conditions. In total of 90 snakehead fish were collected from ditches, paddy fields, and swamps. The observation of ectoparasites was performed on the gills, fins, and skin. The parameters measured in this study were ectoparasite profiles and biometric condition of fish. Specifically, the parameters of the ectoparasite profile included prevalence, intensity, dominance, and predilection. Meanwhile, the parameters of the biometric conditions were the length-weight relationship, the distribution of length and weight classes, and condition factors. Five species of ectoparasites that have been identified as Tetrahymena sp., Epistylis sp., Trichodina sp., Dactylogyrus sp., and Gyrodactylus sp. Tetrahymena sp. infection in snakehead was reported for the first time. The ditch habitat had the highest prevalence and intensity, which were 76.7% and 15.4 ectoparasites/fish, respectively. Tetrahymena sp. and Epistylis sp. were detected in sneakhead from all habitats, Trichodina sp. was detected at ditch and paddy field habitats, whereas, Gyrodactylus sp. and Dactylogyrus sp. were only found in swamp habitats. The gill was the predilection organ that most vulnerable to ectoparasite infection. Infected Snakehead tend to have lower average weight and length than healthy snakehead. Snakehead with a weight range of 115.2-145.2 g and a length range of 258.5-268.5 mm tend to be more vulnerable to ectoparasite infection compared to other sizes.Keywords:Tetrahymena sp.PrevalenceIntensityPredilectionLength-weight relationship

Abstract

Palu is well – known for its local type rainfall patterns but there are no previous studies examining the relationship between its rainfall pattern and ocean dynamics at regional scale and its unique topography in this region.  The aim of this research is to determine the role of ocean dynamics through an analysis of mean sea surface temperatures (SST) and its correlation to rainfall, analysis of precipitable water and zonal-meridional winds against SST and topographic effects on rainfall which causes Palu is having a local type rainfall pattern. The method used in this research is descriptive analysis and quantitative statistical analysis. The results showed that the pattern of precipitable water and zonal-meridional winds follow the pattern of SST which influenced by the sun’s annual motion.  Rainfall in Palu is affected by the SST and moisture from surrounding waters of Palu with varying amounts each month. Local type rainfall patterns in Palu is influenced by a combination of ocean dynamics, land-sea breeze and valley-mountain winds due to geographical location and unique topographic condition.Keywords: Ocean dynamics, Sea surface temperature, Rainfall, pattern local type, Palu city ABSTRAKKota Palu terkenal dengan pola hujan tipe lokal namun belum ada penelitian yang mengkaji wilayah ini untuk mengetahui hubunganya dengan dinamika laut dalam skala regional dan topografinya yang unik.

Abstract

Ectoparasite infections are a common problem in small-scale aquaculture, exerting a substantial influence on fishery production. In the context of Indonesia, the two prevalent fishery commodities are whiteleg shrimpLitopenaeus vannameiiand mud crabScylla serrata. These species are extensively cultured within Aceh province, using traditional and semi-intensive aquaculture ponds and there are no reports on ectoparasites in these two species of crustaceans. Therefore, this study aimed to analyze the intensity and prevalence of ectoparasites in mud crab and whiteleg shrimp from Aceh between August to December 2022. Mud crab samples were collected from three locations, namely Langsa City, East Aceh, and North Aceh districts, while whiteleg shrimp samples were sampled from coastal ponds in Banda Aceh, Aceh Besar, and Aceh Jaya districts. The samples were collected over five months, and a total of 300 for each species were examined microscopically by scraping the swimming legs body, and gills. Furthermore, macroscopic-sized and microscopic-sized ectoparasites were observed using stereo and binocular microscopes, respectively. The results showed that five species of ectoparasites were recorded during the study, namely Octolasmis sp., Vorticella sp., Epistylis sp., Oodinium sp., and Zoothamnium sp. Mud crab exhibited infestations of Octolasmis sp., Vorticella sp., Epistylis sp., and Oodinium sp., while whiteleg shrimp were infested byVorticellasp.,Epistylissp., andOodiniumsp. In this study, the highest intensity for crab and shrimp was recorded inOctolasmissp. and Epistylissp., in November and September, respectively. The gills showed higher intensity compared to other infested organs and based on sample origin, crab and shrimp from Langsa and Banda Aceh Cities had higher results compared to other locations.The prevalence of ectoparasites exhibited a high value, reaching 100%, showing that crustacean samples were infested by ectoparasites. Therefore, the intensity of ectoparasite was varied according to sample of origin, time of sampling and infested organs. The samples of both crab and whiteleg shrimp from all locations consistently exhibited ectoparasite infestations throughout the entire study period.Keywords:Octolasmis sp.Vorticella sp.Epistylis sp.Oodinium sp.Zoothamnium sp.

Abstract

Situ Gede is one of the artificial lakes/reservoirs in Tasikmalaya, West Java. The lake has functioned as a source of household water needs, fisheries, and tourism. According to determine the development of water management requires information on the trophic status and water quality. This study aimed to obtain information on the trophic status and water quality of Situ Gede. The research was conducted in Situ Gede, Tasikmalaya, West Java, in 2018. Measurement and analysis of water quality parameters used the SNI and APHA methods, while the measurement of trophic status used the Carlson Trophic State Index (TSI). The relationship between water quality parameters and TSI scores was analyzed using Statistica version 8. Based on the analysis, the trophic status of Situ Gede ranged from 69.06-79.04, with an average of 74.61. This value indicated that Situ Gede's trophic status was on a eutrophic level. The physical and chemical parameters that affect the trophic status of Situ Gede are TP, pH, conductivity, TDS, and temperature. The TP values, conductivity, pH, and temperature at Situ Gede were still categorized as normal. The trophic of Situ Gede can be a source of fish growth. Moreover, in general, Situ Gede waters still have sufficient water quality for fish life. Therefore, Situ Gede has the potential to capture fisheries, recreational fisheries, and aquaculture.Keywords:Trophic statusSitu GedeFisheryChlorophyll-aFish Reserve

Abstract. At present, marine debris is an important issue in Indonesia. Due to the complex pattern of ocean currents, research on the distribution of marine waste in Indonesia is still very lacking. This study aims to determine the movement of microplastic particles at the Savu Sea National Marine Park. The method used was to simulate the hydrodynamic model and particle trajectory. Data used were wind, tides, bathymetry, coastline, weight of garbage, and garbage fluxes. Analysis was carried out on physical data visualization, hydrodynamic models, and particle trajectory models. The hydrodynamic model simulation shows if the average current velocity ranges from 0,0002 m/s to 0.35 m/s. The particle trajectory showed that microplastic particle movements tend to move to the south, where some of them move west and east of the Savu Sea. Besides being affected by tides, microplastic particle movements in the Savu Sea National Marine Park are also influenced by various currents that pass through the Savu Sea waters, especially by Indonesia Troughflow.Keywords: ocean model, particle pathways, microdebris, Savu Seas, Indonesia Troughflow Abstrak. Saat ini, sampah laut merupakan salah satu isu kemaritiman di Indonesia. Karena pola pergerakan arus yang kompleks, penelitian mengenai distribusi sampah laut di Indonesia masih sangat kurang. Taman Laut Nasional Laut Sawu sebagai wilayah yang dilalui Arlindo juga memiliki karakteristik oseanografi yang kompleks. Penelitian ini bertujuan untuk mengetahui hasil simulasi pergerakan partikel sampah di Taman Nasional Perairan (TNP) Laut Sawu. Metode yang digunakan yaitu simulasi model hidrodinamika dan lintasan partikel. Data yang digunakan yaitu angin, pasang surut, batimetri, garis pantai, berat sampah, dan flux sampah. Analisis dilakukan terhadap visualisasi data fisik, model hidrodinamika, dan model pergerakan partikel. Simulasi model hidrodinamika menunjukkan jika rata-rata kecepatan arus berkisar antara 0,0002 m/s hingga 0,35 m/s. Hasil simulasi menunjukkan jika pergerakan partikel mikroplastik cenderung bergerak ke selatan, dimana sebagian bergerak ke arah barat dan timur Laut Sawu. Selain dipengaruhi pasang surut, pergerakan partikel mikroplastik di Taman Laut Nasional Laut Sawu juga dipengaruhi oleh berbagai arus yang melewati perairan Laut Sawu khususnya Arlindo.Kata kunci: pemodelan, lintasan partikel, sampah mikro, Laut Sawu, Arlindo.
