Environmental DNA, Volume 8, Issue 3, May–June 2026.This study compares the efficacy of conventional surveys of vertebrate taxa to eDNA metabarcoding of freshwater samples from a tropical rainforest ecosystem in the Makira Forest Protected Area (MFPA), Madagascar. We demonstrate high but taxa‐varying efficacy of eDNA metabarcoding detections, reinforcing its use as a complementary biodiversity survey ...

Boletim do Instituto de Pesca, 2020 The migratory behavior of females of the freshwater prawn Macrobrachium amazonicum (Heller, 1862) can indicate a strategy that optimizes the population establishment. With this idea in mind, we evaluated the reproductive biology of M.

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Aquatic and Terrestrial Invertebrates Support Fish Assemblages of Amazonian Streams
Freshwater Biology, Volume 71, Issue 5, May 2026.ABSTRACT The Amazonian stream network is remarkable not only for its extent but also for its rich fish diversity. These streams are interconnected with the surrounding forests. However, key ecological aspects of Amazonian freshwater ecosystems, such as energy flows and carbon sources sustaining fish assemblages, remain poorly understood. In this study,

Transportation of Amazon river prawnMacrobrachium amazonicumjuveniles in different biomass densities
Aquaculture Research, 2012 The Amazon river prawn Macrobrachium amazonicum is widely exploited by artisanal fisheries in the north and north-east of Brazil (Maciel & Valenti 2009). Currently, this species has important potential for aquaculture where it is indigenous (Moraes-Valenti & Valenti 2010; Marques & Moraes-Valenti 2012).

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.Reported environmental impacts of shrimp aquaculture from life cycle assessments (LCAs) vary by over fiftyfold. These discrepancies stem from methodological inconsistencies, which often outweigh actual differences in farming practices. Furthermore, areas of environmental concern including land use change, biodiversity, and toxicity impacts are excluded

Effect of tank colour on larval performance of the Amazon River prawnMacrobrachium amazonicum
Aquaculture Research, 2012 The aim of this study was to evaluate the effects of hatchery-tank colours (white, yellow, red, blue, green and black) on the performance of larval culture of Macrobrachium amazonicum. The larvae were fed daily with newly hatched Artemia nauplii. The hatchery-tank colours affected the light level inside the tanks, the consumption of Artemia nauplii (AN)

Development of a brood stock of the jumbo tiger prawn, Penaeus monodon Fabricius [PDF]
, 1976 The full-scale cultivation of sugpo, P. monodon Fabricius, could only be realized if there is an assurance of continuous supply of fry. Obviously, a steady supply will depend largely on the availability of spawners.
