Sea urchins are vital herbivores in seagrass meadows, but when their numbers surge, grazing can flip a thriving bed into a barren state. This study uses predator–prey population models to map the thresholds where that shift occurs and to identify management levers that keep ecosystems stable. By varying growth, grazing, and mortality rates, the simulations […]
A research team from Universitas Padjadjaran has published a study on the distribution of heavy metals in seawater and sediments along the Cirebon coastal area, West Java. The study measured concentrations of cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn) at Nusantara Kejawanan Fishery Port and Gebang Mekar Fish Landing […]
This field survey documents 59 species of intertidal macroalgae across Pangandaran’s shoreline—spanning green (Chlorophyta), red (Rhodophyta), and brown (Ochrophyta) groups—with the highest cover in Madasari. Two non‑native Ulva species (U. lactuca and U. flexuosa) are particularly dominant. By linking species patterns to habitat type, temperature, nutrients, and tourism pressure, the study explains why some sites […]
A new study led by researchers from Universitas Padjadjaran has revealed the remarkable biodiversity of marine macroinvertebrates along the Pangandaran coast, one of Indonesia’s most prominent ecotourism destinations. The research documented 160 species from 13 classes and 7 phyla, with mollusks being the most dominant group. The findings highlight how substrate types—rocky, muddy, sandy, and […]
Tourism and marine litter are on a collision course along parts of the Tasikmalaya and Garut Coast (TGC) in West Java. This study offers a practical, place‑based way to manage that tension by combining Sector Analysis (SA), the Coastal Scenic Evaluation System, and the Coastal Clean Index. Seven beaches—from the remote Sancang Nature Reserve to […]
A new study published in Marine Biology highlights the urgent conservation needs of two endangered species of devil rays — the Spinetail Devil Ray (Mobula mobular) and the Bentfin Devil Ray (M. thurstoni) — in the Indian Ocean. Researchers found that these rays have extremely low reproductive rates and are highly vulnerable to overfishing. Current […]
A team of researchers from Universitas Padjadjaran, Universitas Pakuan, and Universiti Tun Hussein Onn Malaysia has successfully analyzed the double resonance characteristics of photonic crystal structures with defect metal layers. Using the Finite Difference Frequency Domain (FDFD) method, the study revealed that introducing two defect layers—one metal and one sensing material—produces a double resonance effect […]
A team of researchers from Universitas Padjadjaran and collaborators examined the potential of mangrove ecosystems in Pangandaran, West Java, as a foundation for sustainable ecotourism development. Focusing on three locations—Bulaksetra, Bojongsalawe, and Batukaras—the study combined field surveys, vegetation analysis, water quality assessments, and satellite imagery to measure the mangrove tourism suitability index (TSI). Findings revealed […]
COVID‑19 lockdowns offered a rare, real‑world experiment: what happens to estuaries when human activity slows down—and what happens when it resumes? This study tracks water quality in three Cirebon estuaries (Kesenden, Sukalila, Kalijaga) over 2019–2023, comparing pre‑, during‑, and post‑restriction periods. Using the NSF‑Water Quality Index, the team integrated physical (temperature, turbidity, total solids), chemical […]
A recent study published in BIO Web of Conferences (2025) explores the socio-economic dynamics of small-scale octopus fisheries in East Java, Indonesia. Conducted in Sumenep, Banyuwangi, and Malang, the research highlights how octopus fishing serves as a crucial livelihood for coastal communities, while also facing significant challenges such as climate change, fluctuating market prices, high […]
A recent study published in Trends in Sciences (2025) investigated how cold shock treatments affect larval viability and chromosome manipulation in the Asian redtail catfish (Hemibagrus nemurus). By applying temperature shocks at different times after fertilization, researchers found that a 3-minute cold shock at 6 °C, given 28 minutes after fertilization, produced the highest tetraploid […]
A new study published in the Egyptian Journal of Aquatic Biology & Fisheries (2025) highlights the effectiveness of probiotics in enhancing the growth and feed efficiency of snakehead fish (Channa striata) cultivated in a bucket system. This innovative aquaculture method addresses land scarcity by using small-scale media, making fish farming more accessible and environmentally friendly. […]
