Abstract

Pangkep Regency is dominated by pond areas, one of which is located in Labakkang District. These aquaculture activities affect physico-chemical parameters in the waters. This study was aimed to analyze the influence and relationship of physico-chemical parameters on phytoplankton abundance in the waters of Labakkang District, Pangkep Regency. Data were collected using purposive sampling method in several locations, namely waters around river mouths, waters around mangroves, pond discharge waters and waters around docks. The physico-chemical parameters observed include temperature, salinity, nitrate, phosphate, Total Suspended Solid (TSS), carbon dioxide and current velocity. The results showed that the highest phytoplankton abundance was found in the waters around the river mouth with a value of 741 cells/L, while the lowest abundance was found in the pond discharge waters with a value of 154 cells/L. At the station, the highest values were obtained in the temperature parameter of 32,67ºC, nitrate of 0,03 mg/L, phosphate of 0,08 mg/L, TSS of 25,26 mg/L and current speed of 0,25 m/s. The high abundance of phytoplankton is inversely proportional to the salinity level in the water, which is 29%ₒ. The results of the analysis using the one-way ANOVA statistical test showed significant differences in phytoplankton abundance as well as temperature, salinity and TSS parameters between sampling stations. Then multiple regression analysis showed that the most influential parameters on phytoplankton abundance were temperature, nitrate, and TSS with a coefficient of determination of 92,8%. The results of this study can serve as a basis for more effective water management and better environmental monitoring in the context of aquaculture activities in the region.

Abstract

The exploitation level of fish resources should be based on effectiveness, efficiency and business sustainability. One of the efforts to implement these three aspects is to understand the seasonal pattern or the best time to catch the fish target. The aim of this research was to estimate the pattern of the anchovy fishing season based on production data landed at PPI Paotere Makassar, South Sulawesi. Data is collected from the PPI and analyzed using the moving average techniques. Results showed that the seasonal pattern of anchovy fishing is estimated to increase in the transition season to the eastern season (IMP > 100%) and reach a peak in September (IMP = 134.74%). Descriptively, the fishing season, especially the peak season, was thought to occur because these fish are probably associated with optimum conditions for oceanographic parameters such as sea surface temperature, chlorophyll-a concentrations and surface current conditions. Information on anchovy fishing season patterns is really needed by marine fisheries managers, both government and private, in managing efforts to exploit fish resources wisely and sustainably.

Abstract

The recent adoption of environmental DNA (eDNA) represents an innovative method for assessing the presence of aquatic vertebrate species, providing a relatively straightforward approach with significant implications for conservation biology. In our investigation, we employed eDNA metabarcoding to explore the diversity of fish in the Makassar Strait. We collected eDNA from samples taken both at the surface and from the water column (15 m depth) at two specific locations within this region. The reliability of the MiFish-U primer set methodology in estimating fish diversity in the Makassar Strait was assessed. In a single survey, based on four water samples from the Makassar Strait, we successfully identified 11 marine fish taxa at the species level. These taxa belong to 8 families across 8 orders. The predominance of reef-dwelling species suggests that coral reefs play a dominant role as the primary ecosystem in this area. Among the surveyed sites, Barru Waters exhibited the highest species richness (7 species), while Pangkep Waters only revealed 4 species. Through the application of eDNA metabarcoding, this study provided a means to assess fish diversity, delivering crucial foundational information. Our findings highlight the cost-effectiveness of the eDNA metabarcoding method as a powerful scientific tool for the management and conservation of marine fish resources in the Makassar Strait.

Abstract

This study presents a comprehensive checklist of sea cucumber species found in Biluhu Timur waters, Tomini Bay, Gorontalo, Indonesia, across the new moon and full moon lunar phases. The survey identified eight species across five genera, including Actinopyga miliaris, A. mauritiana, Holothuria scabra, and H. leucospilota, noting significant distribution patterns influenced by lunar cycles and different biomes at three stations. Actinopyga miliaris and A. mauritiana, both classified as Vulnerable, were more active in the seagrass biome of Station I during the full moon. H. leucospilota, classified as Least Concern, was highly prevalent in the sandy substrate biome of Station II during the new moon, indicating a strong ecological association with that habitat. Stichopus horrens, classified as Data Deficient, showed notable activity in the coral reef biome of Station III. Environmental parameters such as water temperature, salinity, and pH were measured at each station to understand the conditions influencing these species. This study highlights the importance of lunar phases, biomes, and environmental variables on sea cucumber distribution. The findings underscore the need for conservation efforts that consider these factors to protect species vulnerable to overfishing and habitat degradation. Further research should include genetic analysis and expanded temporal and spatial scales to develop effective conservation strategies and sustainable management practices

Abstract

Halimeda is a genus of calcified alga that inhabits tropical aquatic environments. The presences of Halimeda is essential for waters around mining sites, such as the waters of Maba District, wich is the center of mining in East Halmahera. As a calcareous organism, Halimeda functions as a buffer to neutralize the pH of waters. Although the presence of Halimeda in waters is not rare, studies on Halimeda taxonomy in Indonesia are very limited. Identification of Halimeda species can be done by looking at morphological and anatomical structures as an alternative based on the key to determining Halimeda species in the Indo-Pacific by Hillis & Collinvaux (1980), in addition to looking at DNA sequences. This study was aimed at identifying Halimeda species distributed in the waters of Maba District, East Halmahera based on morphological and anatomical characteristic. Besides, it also aims to determine the distribution and similarity of species between sampling locations. Sampling was carried out using purposive sampling method. Halimeda sample collection was prepared before identification. Eight species of Halimeda were found from four sampling sites, namely Halimeda cylindracea, H. distorta, H. macroloba, H. opuntia, H. simulans, H. discoidea, H. melanesica, and H. tuna. In additional to these eight species, seven unidentified Halimeda species were also found based on morphological and anatomical characteristc. Most similarity percentage of Halimeda species was found between Tanjung Buli-Monoropo at 75% and the lowest between Gee Island-Pakal Island (0%). The distribution of Halimeda species in waters in influenced by many factors, including substrate type, nutrients, light intensity, salinity, pH, temperature, depth, wave and current action.

Abstract

ABSTRACT Sicyopus zosterophorus (Gobiidae) has a habitat in clear and fast-flowing rivers. This fish species is found in several rivers in Banggai Regency, Central Sulawesi, one of which is the Bohi River. Studies on the type of food S. zosterophorus in the Bohi River have never been carried out. Therefore, it is necessary to conduct research that aims to determine the type of food S. zosterophorus in nature as important information for life history and feeding in controlled habitats. This research was carried out from December 2019 to January 2020. The fishing was done using a scoop net by snorkeling to get fish at the bottom of the river. The fish obtained were then preserved using 5% formalin and then taken to the laboratory for identification of digestive tract contents. Data on the composition and percentage of types of food in the digestive tract were processed using Microsoft Excel 2010 and analyzed descriptively. The results showed that the contents of the digestive tract of S. zosterophorus were dominated by insects (74%), crustaceans (7%), plants (5%), and phytoplankton (3%). The contents of the digestive tract were not identified as much as 11%. Based on this, S. zosterophorus in the Bohi River is categorized as stenophagic and is a carnivorous fish, especially insectivorous and phytobenthic eaters. This research can be used as a basis for providing natural food for S. zosterophorus in aquaculture. Keywords: Goby fish, insectivorous, phytobenthic, stenophagic

Abstract

As the population increased, the requirement for housing increased as well. The Randuputih coastal area on the coasts of Probolinggo Regency is located in the northern part of Java Island, so most residential areas are in the north coastal area. In this area, there is housing development close to the coastal area. With the housing development near the Probolinggo coastal area, we plan to build a coastal protection building as a groin structure to prevent erosion along the coast. In designing the groin structure, it is necessary to analyze the coastline changes in the Randuputih coastal area, Probolinggo Regency, to calculate the length of the groin built in that area. As a reference for calculating the groin structure, the analysis carried out observed changes in the coastline over 20 years (2003-2023). The sediment transport method used is the Ijima Sato sediment transport method because this method approximates changes in coastlines based on observations over 20 years in the Randuputih coastal area, Probolinggo Regency. The average sediment transport is 3.74 m3/day from the northwest. Adding three groin structures along 700m can maintain coastline change stability by up to 6.61%. Before the groins were applied, the average coastline change was 34%.

Abstract

This study sought to evaluate the quality of benthic organisms and coral fish, as well as analyze the coral reef conservation index in the waters surrounding Samalona Island. The research was conducted in the northern, southern, and western waters of Samalona Island, encompassing five reef zones: reef flat, reef crest, upper and lower reef slopes, and reef base. The line intercept transect (LIT) method was employed in conjunction with the belt transect for the collection of benthic data, while the underwater visual census (UVC) was utilized for capturing reef fish data. Further assessments of the quality of benthic organisms and reef fish were conducted using the suspension technique outlined by McMellor (2007). The findings indicated that the quality of coral reef organisms on Samalona Island was suboptimal, with scores of 21, 19, and 28 for the southern, western, and northern sides, respectively. The quality of reef fish was categorized as moderate-low, with scores of 27, 31, and 33 on the southern, western, and northern sides of the island, respectively. Consequently, the coral reefs in the waters surrounding Samalona Island were evaluated using the D3–D4 conservation index for both the southern and western sides of the island. Although the northern side has a conservation index of E3 and includes degraded habitat, it is not recommended for designation as a conservation area.

Abstract

Banyuwangi Regency has 282 km of coastline with high coastal potential to be developed, such as tourism, fisheries, and ports. This study aimed to analyze the suitability of the Tanjung Wangi Port location based on tidal and ocean current data. Tidal data were obtained from the Indonesian Hydrographic Data Center (IHDC), and ocean current data were obtained from AVISO Satellite Altimetry. The data were processed using Microsoft Excel and ArcGIS using the inverse distance weighted (IDW) method to create ocean current maps. The results showed that Tanjung Wangi Port has a double-dominant mixed tidal type. The highest water level was recorded at 5.207 m, and the lowest water level was 0.809 m, with a Mean Sea Level (MSL) of 3.048 m. The sea current speed ranged from 0.023 m/s to 1.414 m/s from the Southeast and Southwest Indian Ocean, with the direction of the sea current towards the Banyuwangi Regency. Stable tidal conditions and low ocean currents make the Tanjung Wangi Port ideal for safe harbor and navigation activities and contribute positively to the effectiveness of port activities. Further research should involve direct field surveys and seasonal variability analyses to improve the accuracy of port planning.

Abstract

Global warming represents a significant challenge, primarily driven by the escalating concentrations of greenhouse gases in the atmosphere, notably carbon dioxide (CO₂). Mangrove ecosystems are integral to climate change mitigation due to their capacity to sequester and store carbon within their biomass and sediment. This study sought to evaluate carbon sequestration through the analysis of organic carbon content in the sediments of mangrove ecosystems located in Ampekale, Maros Regency. Sampling was executed using a purposive sampling method across nine sites, employing a 50 × 5 cm corer. Each sediment sample was sectioned into five depth intervals (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm). The organic carbon content was assessed using the loss on ignition (LOI) method, with parameters measured including bulk density, sediment organic carbon concentration, carbon storage, and carbon uptake in sediments. Statistical analyses were conducted utilizing one-way and two-way ANOVA tests. The findings indicated that the mangrove ecosystem in Ampekale exhibited a total carbon storage in sediments of 731.72 tons/ha, with a total carbon uptake of 2685.42 tons/ha. The greatest carbon storage and uptake were observed at the 40-50 cm depth, with values of 342.056 tons/ha and 1255.34 tons/ha, respectively.
