Teluk Biru, yang merupakan daerah penangkapan bagan apung di Selat Bali, berperan penting dalam mendukung produksi perikanan ikan Clupeiformes di Muncar dan wilayah sekitar Selat Bali. Penelitian ini bertujuan untuk mengevaluasi komposisi spesies dan pola pertumbuhan hasil tangkapan Clupeiformes di Teluk Biru dan keterkaitannya dengan parameter lingkungan. Pengambilan contoh dilakukan selama musim barat (Desember 2023, Februari 2024) dan musim peralihan-1 (Maret–April 2024). Analisis data mencakup penilaian komposisi spesies, hubungan panjang-bobot, faktor kondisi, variabilitas spasio-temporal parameter oseanografi, dan Analisis Korespondensi Kanonik. Tangkapan Clupeiformes selama kedua musim terdiri atas enam spesies, dengan adanya variasi bulanan pada spesies dominan. Sebagian besar individu merupakan fase yuwana, kecuali Spratelloides delicatulus yang banyak ditemui stadia dewasanya. Mayoritas spesies memiliki pertumbuhan alometrik positif dan berada dalam kondisi pertumbuhan yang baik (FK > 1,00). Parameter fisik-kmiawi perairan berbeda signifikan antarwaktunya dan mendukung kehidupan ikan di dalamnya. Klorofil-a cenderung menurun pada musim barat dan meningkat menjelang musim peralihan-1, berbanding terbalik dengan suhu permukaan laut. Terdapat empat parameter lingkungan utama yag berasosiasi dan berpengaruh signifikan terhadap komposisi ikan Clupeiformes, yakni suhu, salinitas, oksigen terlarut, dan klorofi-a. Status sumber daya Clupeiformes di Teluk Biru berada dalam lingkungan yang sesuai, namun mengalami tekanan penangkapan dari bagan apung, terutama pada anak-anak ikan.

Bedetan Perancak is an innovative sardine processing product (cat sardine and protolan types) made by the Bedetan Perancak Women Farmers Group (KWT) in Jembrana Regency. It is dried using an eco-friendly Solar Dryer Dome (SDD) technology with a capacity of 200 kg per 3 days. This study compares the nutritional content of two Bedetan variants—unseasoned and seasoned—both dried using SDD. The analysis covers moisture, ash, protein, fat, carbohydrates (by difference), and estimated energy (kcal). Results indicate that moisture and ash are higher in the seasoned variant at 11.38% and 7.23%, respectively. Protein content is high in both variants: 62.89% (unseasoned) and 63.81% (seasoned). Fat content is similar, ranging between 15.03% and 15.13%. Carbohydrates are higher in the unseasoned variant (5.89%) than in the seasoned one (2.54%). Energy values are 411.30 kcal (unseasoned) and 400.70 kcal (seasoned). Adding seasoning affects moisture and ash but not protein and fat significantly. Both variants meet the SNI 8273:2023 standard for dried fish moisture (max 40%; ideal 15–20%), with moisture well below ideal limits. This shows that SDD technology is environmentally friendly and enhances nutritional quality and shelf life of Bedetan.

Yellowfin tuna (Thunnus albacares) is one of Indonesia’s leading fishery commodities, with high potential as a raw material for fish oil, especially from the eye tissue, which is rich in omega-3 fatty acids. This study aimed to evaluate the heavy metal content in yellowfin tuna eyes from Aceh waters to ensure the safety of extracted fish oil. Eye samples were obtained as by-products from a tuna fillet processing industry in Banda Aceh. Preparations were carried out by separating soft tissues from hard parts, followed by oil extraction using the cold water extraction method. Characterization included morphometric analysis and determination of heavy metal contents (Hg, Pb, Cd, As) using Atomic Absorption Spectrophotometry (AAS), based on national (SNI) and international (Codex Alimentarius 2017) standards. Results showed that Hg, Pb, and Cd were not detected, while As was present at a concentration of <0.005 mg/kg—well below safety thresholds. These findings indicate that yellowfin tuna eye oil from Aceh is safe for consumption and holds promising potential as a high-value functional food or dietary supplement ingredient.

The transition of Saccharina japonica var. ochotensis (Rishiri Kombu) from its first to second year of growth is crucial for commercial harvest. However, recent increases in seawater temperature and nutrient depletion are likely to influence this process. This study investigates the influence of autumn seawater temperature and nitrate concentrations on the second-year transition rate of Rishiri Kombu in northern Hokkaido. Field surveys were conducted from 2020 to 2024 at Ishikari and Rebun, where the population densities of first- and second-year individuals were quantified. Concurrently, in situ measurements of seawater temperature and nitrate concentrations were performed during autumn. The results indicate that higher seawater temperatures tend to be associated with lower second-year transition rates, whereas increased nitrate concentrations positively correlate with transition success. Statistical analyses suggest that nutrient availability has a stronger influence on transition rates than temperature changes. These findings suggest that nitrate depletion is a key limiting factor for the sustainability of Rishiri Kombu, highlighting the importance of monitoring climate-driven changes in nitrate availability in coastal ecosystems.

This study aims to analyze garbage waste data by day in a week at the Cituis Fish Landing Base (PPI Cituis), identify the causes of waste issues, and provide recommendations for waste management and handling. The research was conducted over two weeks of observation. Data were collected through waste characterization, total and average garbage waste volume measurements, the number of waste containers, and waste type composition from several source points. The results show that waste volume tends to increase at the end of the month, on weekends, and during holidays, following higher visitor numbers and fishing activities. Inorganic waste, especially plastic was the most dominant type across all port zones. The 3 kg container representing the harbor area had the highest percentage of waste bins compared with the 4 kg and 10 kg containers. Proper waste management is necessary to minimize pollution impacts at PPI Cituis and the surrounding environment. Recommended actions include improving waste facilities, strengthening governance and regulations, and enhancing community awareness and participation.

Target reef fish possess significant economic value as food and ornamental sources, yet they are highly vulnerable to anthropogenic pressures and overfishing. Pramuka Island, serving as the administrative center and a primary marine tourism destination in the Seribu Islands National Park, plays a critical role in the sustainability of marine resources. This study aims to analyze the family composition, abundance, and biomass of target reef fish in the waters surrounding Pramuka Island. Observations were conducted using the Underwater Visual Census (UVC) method at six observation stations across two depth levels. The results revealed a total abundance of 1,711 individuals, heavily dominated by the families Pomacentridae (72,88%) and Caesionidae (15,78%). The highest abundance was recorded at the SPG station (73,17 ind/100m²), whereas the lowest was found at the BPR station (23,83 ind/100m²), which is characterized by high anthropogenic activity. The highest biomass value was observed at the BSK station, reaching 1600,29 gram/100m². Size structure analysis of the dominant species, Caesio cuning, indicated that the individuals found were below the Length at First Maturity (Lm), categorizing the stock as not yet catchable. These findings highlight the urgent need for appropriate fishery management strategies to prevent growth overfishing and ensure stock sustainability.

Kelp bed degradation due to environmental changes and overgrazing by herbivores such as sea urchins has raised concerns about the sustainability of coastal ecosystems and fisheries in northern Japan. Over a 35-year period (1985–2020), population dynamics of the northern sea urchin Mesocentrotus nudus were monitored in Shimamaki Village, southwestern Hokkaido, focusing on age-specific density fluctuations. First-year juvenile recruitment varied substantially, while adult density showed smaller fluctuations but a long-term declining trend. No significant correlation was found between juvenile recruitment and adult density, or between adult density and catch volume. Field data were collected through annual scuba surveys using 1 m² quadrats, and age was determined by test diameter and genital plate rings. Statistical relationships were assessed using Spearman’s rank correlation. The weak correlation suggests that post-recruit mortality, food limitation due to kelp loss, and harvesting pressure may decouple recruitment from adult population size. These findings imply that sustainable sea urchin fisheries require more than just enhancing recruitment; ecosystem-based management including macroalgal restoration is essential. Understanding the role of Isoyake in reducing kelp availability provides critical insight into population stability and fishery yields in northern Japan.

Although many coral transplantation activities have been carried out, insufficient attention has been given to the optimal depth at which transplanted corals are placed. Therefore, it is necessary to conduct research on the growth of transplanted corals at different depths. This study aimed to determine how different depths affect the growth and survival of Acropora sp. The study used an experimental method involving three treatments at different depths: 2, 4, and 6 metres. The research was conducted over a period of three months on the coast of Kaung Island Village in Sumbawa Regency. The results showed that the highest growth and survival rates were found at a depth of 4 metres.

Plastic is a synthetic material that is widely used by people in everyday life, in recent years the increase in production and use of plastic has become one of the most pressing environmental issues in the world. The high use of plastic combined with the low ability of plastic to decompose causes the accumulation of plastic waste in the environment, the results of the degradation process in plastic will change the plastic to be easily decomposed and turn into very small plastic particles called microplastics. This study aims to identify the characteristics and abundance of microplastics found in milkfish (Chanos chanos) and tilapia (Oreochromis niloticus) sold at Ciruas Market. Fish sampling was carried out using a purposive sampling technique during the period November to December 2024, with a total of 18 fish. The results showed that all fish samples were contaminated with microplastics, especially in the form of fibers, with black, white, red, brown, and transparent colors, and particle sizes ranging from 1–2 mm. Identified plastic polymers include Polypropylene (PP), Nylon, Polystyrene (PS), Low Density Polyethylene (LDPE), and Polycarbonate (PC).

Heavy metal contamination is an important environmental issue, particularly in developing countries where mining activities are widespread and environmental management is often limited. This study evaluated the level of heavy metal contamination in Lake Belibis, a post-mining pit lake formed by illegal artisanal gold mining activities in West Kalimantan, Indonesia, which is currently used as a natural tourism area. Water and sediment samples were collected from three purposively selected stations representing different surrounding land uses from May to August 2024. Concentrations of mercury (Hg), cadmium (Cd), copper (Cu), and lead (Pb) were analyzed using Atomic Absorption Spectrophotometry (AAS). In addition, supporting physico-chemical parameters were measured in situ. The results show that heavy metal concentrations in both water and sediment were generally below applicable environmental quality standards, indicating a relatively low level of contamination under current conditions. The physico-chemical characteristics of the lake reflect stable support the retention of heavy metals in particulate matter and sediments. Overall, the findings suggest that the environmental risk associated with heavy metals in Lake Belibis is currently low, but continuous monitoring is necessary to support environmental risk evaluation and sustainable management of the pit lake.
