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).

Landscape Genomics and Evolutionary History of Megamelus scutellaris, a Biocontrol Agent of the Invasive Water Hyacinth (Pontederia crassipes)

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

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)

YOLOViT‐DETECT: A Hybrid Approach for Real‐Time Fish Species Detection and Classification in Aquaculture

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose YOLOViT‐DETECT, a hybrid model combining an enhanced YOLOv8 with a spatial attention module for fish detection and a ViT‐B/16 transformer for species classification. The method achieves high accuracy in challenging underwater environments, outperforming standalone models.

Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...

Constructed wetlands for treatment of harvest effluents from grow-out ponds of the Amazon river prawn

Aquaculture Research, 2014
Effluent discharges from aquaculture can reduce water quality in receiving water bodies and that strategies or practices to reduce this are necessary. One possibility is to reduce, or eliminate, water renewal in grow-out ponds. In this study, we eliminated water renewal in grow-out ponds associated with the culture of 40 individuals m−2 of Amazon river

The ultrastructural evaluation of digestive cells in the hepatopancreas of the Amazon River prawn,Macrobrachium amazonicum

Aquaculture Research, 2014
The Amazon River prawn Macrobrachium amazonicum is endemic to tropical South America and is being intensively exploited by artisanal fisheries in Brazil. Limited information is available about the nutritional requirements of M. amazonicum, although the production of this species is now technically feasible.

Ontogenetic Variation in Ammonia Excretion during the Early Life Stages of the Amazon River Prawn, Macrobrachium amazonicum

Journal of the World Aquaculture Society, 2010
Dry mass (DM) and total ammonia‐N (TAN) excretion were determined in embryos, larvae (ZI–ZIX, Z = zoea ), and postlarvae (PL) at 1, 7, and 14 d after metamorphosis (PL1, PL7, and PL14) of Macrobrachium amazonicum. Animals in postmolt–intermolt (A–C) stages were sorted according to their developmental stages, and placed into incubation chambers (∼ 30 ...
