A Baseline of Fish Species Richness Through eDNA Metabarcoding in an Understudied Tropical Mangrove Coast of Java, Indonesia

open access: yesEnvironmental DNA, Volume 7, Issue 6, November–December 2025.
This study demonstrates the use of environmental DNA metabarcoding of fish in a highly diverse but poorly described tropical mangrove ecosystem along the North coast of Java, Indonesia. Our results indicate eDNA metabarcoding can capture temporal differences and provide a baseline for fish diversity for future (eDNA metabarcoding) biodiversity studies ...

Reproductive biology of two marine catfishes (Siluriformes, Ariidae) in the Sepetiba Bay, Brazil [PDF]

open access: yesRevista de Biología Tropical, 2014
Marine catfish are abundant in the Sepetiba Bay, a 305 km2 area in Southeast Brazilian coast (Lat. 22 degrees 54' - 23 degrees 04' S: Long. 43 degrees 44' - 44 degrees 10' W), but the knowledge on their biology is still scanty. The reproductive biology of Sciadeichthys luniscutis (Valenciennes 1840) and Genidens genidens (Valenciennes 1839) was studied
