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).

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)

Insights Into the Comprehensive Carbon Cycle in a Mangrove Ecosystem: A Case Study for Understanding Carbon Burial, Outgassing, and Outwelling in a Subtropical Island

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract A significant quantity of soil organic carbon (SOC) is buried in mangrove ecosystems. However, recent research has revealed that substantial amounts of carbon are exported to the atmosphere as CO2 or to the ocean as dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), and particulate organic carbon (POC).

Improving the Efficiency of Lambari Production and Diet Assimilation Using Integrated Aquaculture with Benthic Species

, 2021
A single farmed fish species assimilates about 20% of the nutrients in the supplied diet. This study evaluated if the culture of complementary ecological-function species can recover nutrients dispersed into water and transform them into high-valued ...

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 ...

Variation in egg size of the fresh-water prawn Macrobrachium amazonicum (Decapoda: Palaemonidae) [PDF]

, 1996
Egg size of the fresh-water prawn Macrobrachium amazonicum varied among ecologically isolated or geographically distant populations of the Amazon basin. The mean volume of both recently spawned nonpigmented eggs and older pigmented eyed eggs was smaller ...

Differential life-history traits in geographically isolated populations of the Amazon River prawn, Macrobrachium amazonicum, suggest speciation

, 2009
The Amazon River prawn, Macrobrachium amazonicum (Heller, 1862), is considered as a species with an extremely wide geographic range of distribution, including the Caribbean coasts of northern South America (Venezuela), the Amazon and Orinoco basins, and ...

The Predation of Artemia Nauplii by the Larvae of the Amazon River Prawn, Macrobrachium amazonicum (Heller, 1862), is Affected by Prey Density, Time of Day, and Ontogenetic Development

, 2012
The present study analyzed the effects of prey density, the time of day, and ontogenetic development on the predation of Artemia nauplii by the larvae of the Amazon river prawn, Macrobrachium amazonicum, as well as possible synergy among these factors ...
