Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Metabolismo de rutina de Hoplias malabaricus malabaricus (Bloch, 1974) (Osteichthyes, Erythrinidae) [PDF]

Revista Brasileira de Zoologia, 1982
The routine metabolism of Hoplias m. malabaricus in relation to weight, at 3 different experimental temperatures (15, 20, 30oC), through oxygen consumption in confinement and in the absence of external stimuli was studied. The metabolic index (mg O2/g.h) and the intensity of metabolism (mg O2/g.h), for each temperature, were obtained.

Acute and subchronic effects of petroleum on the freshwater fish Hoplias aff. malabaricus [PDF]

Brazilian Journal of Biology
Abstract Petroleum water soluble fraction (WSF) impairs organisms, but damages may vary among cell and tissue levels. The aim of the present study was to evaluate the acute (24 h, 48 h, 72 h) and subchronic effects (36 days) of WSF (0%, 25% and 100%) in juveniles of the Neotropical top predator fish Hoplias aff. malabaricus.

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences
