From lecithotrophy to planktotrophy: ontogeny of larval feeding in the Amazon River prawn Macrobrachium amazonicum [PDF]

Aquatic Biology, 2009
During downstream transport from rivers to estuaries, early larval stages of the Amazon River prawn Macrobrachium amazonicum (Heller 1862) are likely exposed to planktonic food limita- tion. In the laboratory, we studied the effects of presence or absence of food on larval survival, moult- ing and biomass (dry mass, and content of carbon, hydrogen and ...

Gross energy levels in practical diets for the Amazon river prawn postlarvae, Macrobrachium amazonicum

Latin American Journal of Aquatic Research, 2023
The present study evaluated the effect of different energy levels (15.07, 15.91, 17.17, 18.00, and 19.68 kJ g-1 of diet) on isoproteic practical diets for Macrobrachium amazonicum during the nursery phase on the zootechnical performance and proximate composition of the whole body.

Genetic variability of the Amazon River prawn Macrobrachium amazonicum (Decapoda, Caridea, Palaemonidae) [PDF]

Contributions to Zoology, 2011
The freshwater prawn Macrobrachium amazonicum is widely distributed in South America, and occupies habitats with a wide range of salinities. Several investigations have revealed the existence of wide intraspecific variability among different populations, although the understanding of this ...

Effect of Water Exchange and Mechanical Aeration on Grow‐out of the Amazon River Prawn in Ponds [PDF]

Journal of the World Aquaculture Society, 2013
AbstractExchange and aeration of pond water are common practices in semi‐intensive freshwater prawn culture, but there is lack of scientifically based information on the results. We evaluated the effects of water flow through the ponds and mechanical aeration in semi‐intensive cultures of Macrobrachium amazonicum.

The androgenic gland in male morphotypes of the Amazon River prawn Macrobrachium amazonicum (Heller, 1862)

General and Comparative Endocrinology, 2019
Sexual differentiation and primary and secondary sexual characteristics in male crustaceans are modulated by hormones produced in the androgenic gland (AG). The AG is also responsible for the determination of morphotypes in caridean shrimps, such as Macrobrachium amazonicum that shows four morphotypes: translucent claw (TC), cinnamon claw (CC), green ...
