Effect of Habitat Diversity on Population Development of the Amazon River Prawn

Journal of Shellfish Research, 2016
ABSTRACT The aim of this study was to determine if the Amazon river prawn [Macrobrachium amazonicum (Heller, 1862)] population structure is affected by habitat heterogeneity. An experiment was conducted in mesocosms to emulate conditions from a natural aquatic environment. Twelve rectangular earthen ponds of ∼100 m2 each were used as mesocosms.

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

Invasive giant river prawns as opportunistic, generalist predators in the Amazon Delta: Insights from metabarcoding

Ecosphere
Invasive species alter habitats and biological communities. The giant river prawn Macrobrachium rosenbergii (de Man 1879) was introduced to Brazil for aquaculture, and invasive populations have established in the Amazon Delta region where they are ...

Silicate rock weathering and atmospheric/soil CO2 uptake in the Amazon basin estimated from river water geochemistry: seasonal and spatial variations [PDF]

, 2003
Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into
