Aquaculture producers need practical, low‑cost levers to improve spawning success without increasing environmental pressure. This research tests two such levers—photoperiod (day–night cycles) and water temperature—on hormone profiles that control the reproductive cycle of female African catfish (Clarias gariepinus). The team measured melatonin, growth hormone, estradiol, and vitellogenin under controlled regimes, then linked hormonal responses to […]
Researchers from Universitas Padjadjaran have published a new study, “Projected Impacts of Ocean Warming on the Potential Fishing Zone of Eastern Little Tuna (Euthynnus affinis) in the Java Sea” in the Egyptian Journal of Aquatic Biology & Fisheries (Vol. 29, 2025). Using satellite-derived sea surface temperature (SST), chlorophyll-a, and salinity data from 2016–2020, the team […]
This study explores the global landscape of research on biosurfactants—naturally derived surface-active compounds from microbes—focusing on their potential as antimicrobial agents. With the growing crisis of antimicrobial resistance, scientists are increasingly turning to biosurfactants for their biodegradable, non-toxic, and environmentally friendly properties. Using bibliometric analysis of 908 publications indexed in Scopus between 1991 and 2023, […]
A recent study led by Universitas Padjadjaran has investigated the contamination of pathogenic bacteria in vannamei shrimp (Litopenaeus vannamei) farming areas along the Pangandaran coast, West Java. Researchers analyzed pond water, seawater, and sediment samples from five stations and found that sediment contained the highest bacterial loads (2.854×10⁷ CFU/g), including harmful species such as Vibrio […]
A new study published in the Egyptian Journal of Aquatic Biology & Fisheries (2025) examines the threats facing freshwater amphidromous goby fish in the Cimaja River–estuary, Sukabumi, Indonesia. These migratory fish, which move between freshwater and marine habitats, face both internal threats such as low egg survival and high larval mortality, and external threats from […]
A new study published in the Egyptian Journal of Aquatic Biology & Fisheries (2025) explored the role of Bacillus subtilis CgM22—a probiotic bacterium isolated from fish intestines—in boosting the immune system of common carp (Cyprinus carpio). Researchers identified antimicrobial peptide (AMP) genes such as surfactin (SrfAA) and subtilin (SpaS), which demonstrated strong antibacterial potential. Feeding […]
Original Title: Evaluation of the nutritional value of fermented pangasius fish waste and its potential as a poultry feed supplement SDGs Connection Secondary SDGs: SDG 2 – Zero Hunger, SDG 14 – Life Below Water Narrative Explanation A research team from Universitas Padjadjaran explored an innovative way to transform pangasius fish processing waste into a […]
This study investigates the presence and distribution of lead (Pb), a highly toxic heavy metal, in the Flores Sea—an important maritime corridor in Eastern Indonesia. The researchers measured lead concentrations at different depths and sediments, using Atomic Absorption Spectroscopy (AAS), during the Jala Citra 3 Expedition (April–May 2023). The results revealed that lead levels exceeded […]
This study investigates the alarming presence of microplastics in the coastal ecosystem of Pangandaran, Indonesia, focusing on their accumulation in commercially important fish species—mackerel tuna and lemuru—as well as in seawater samples. Researchers collected fish samples landed by coastal trawlers and seawater along fishing routes on the East Coast of Pangandaran. Using laboratory methods including […]
A research team from Universitas Padjadjaran conducted a study to help identify the most productive fishing areas in Jatigede Reservoir, West Java, using satellite technology. This reservoir, which spans more than 4,000 hectares, is vital for electricity generation, irrigation, and fisheries. However, local fishers often rely only on experience to choose fishing sites, which limits […]
A collaborative research led by Universitas Padjadjaran and University Malaysia Terengganu has explored chlorophyll-a and nutrient dynamics in the Eastern Tropical Indian Ocean (ETIO) during the 2022–2023 La Niña event. The study revealed strong vertical stratification of nitrate, phosphate, and silicate, with a well-defined nutricline around 100 meters depth. Seasonal monsoon-driven upwelling along Java’s southern […]
Researchers from Universitas Padjadjaran have successfully developed an edible coating enriched with nanochitosan to preserve the quality of Pangasius (Pangasius sp.) fillets during storage. The study demonstrated that a 2% nanochitosan-incorporated coating significantly reduced weight loss, maintained neutral pH levels, and inhibited bacterial growth—allowing fillets to stay fresh and safe for consumption for up to […]
