In silico prospecting of the mtDNA of Macrobrachium amazonicum from transcriptome data [PDF]

BMC Genomics, 2023
Background Macrobrachium amazonicum is a freshwater prawn widely distributed in South America that is undergoing speciation, so the denomination “M. amazonicum complex” is used for it.

Fecundity and fertility of Macrobrachium amazonicum (Crustacea, Palaemonidae) [PDF]

Brazilian Journal of Biology, 2004
In Brazil, studies with native freshwater prawn species were discontinued due to great importance of Macrobrachium rosenbergii. Therefore, it is necessary to continue investigations about our species, in order to develop technology adequate to our reality and in a future allow prawn farmers to culture other species.

Reproductive cycle of Macrobrachium amazonicum females (Crustacea, Palaemonidae) [PDF]

Brazilian Journal of Biology, 2007
Macrobrachium amazonicum is considered a favorite Brazilian species of freshwater prawn for cultivation as a result of its quick development and because it is easy to maintain in captivity. The aim of this work is to describe the sexual cycle stages and determine maturation age of the female M. amazonicum, which was collected monthly from June, 2002 to

Global consequences of dam-induced river fragmentation on diadromous migrants: a systematic review and meta-analysis. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

Macrobrachium amazonicum: an alternative for microbiological monitoring of aquatic environments in Brazil [PDF]

Ciência Rural, 2014
This study aimed to evaluate the role of the Amazon River prawn, Macrobrachium amazonicum, as carrier of Candida spp., by analyzing the correlation between Candida spp. from these prawns and their environment (surface water and sediment), through M13-PCR

Has a river dam affected the life‐history traits of a freshwater prawn? [PDF]

Ecology and Evolution, 2020
In recent years, species richness and diversity in aquatic ecosystems has declined as environments are increasingly impacted by anthropic actions. Freshwater prawns are well adapted to survive in a disturbed and heterogeneous environment.

Effect of density on population development in the Amazon River prawn Macrobrachium amazonicum [PDF]

Aquatic Biology, 2010
The Amazon River prawn Macrobrachium amazonicum is widely distributed in lentic and lotic environments of South America, and shows different male morphotypes. In the present study, the effect of crowding on the general population structure of this species and its variation over time were evaluated.
