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
Exchange 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

Effects of Ambient Nitrite on Amazon River Prawn, Macrobrachium amazonicum, larvae.

Journal of the World Aquaculture Society, 2014
The effects of nitrite concentration on larval development of Amazon river prawn, Macrobrachium amazonicum, were studied in laboratory. In Experiment 1, larvae were reared in 600-mL glass beakers filled with 300-mL water with nitrite concentration of 0 ...

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

Aquaculture Research, 2015
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 Silico Identification of the Laccase-Encoding Gene in the Transcriptome of the Amazon River Prawn Macrobrachium amazonicum (Heller, 1862). [PDF]

Genes (Basel)
Background: Macrobrachium amazonicum is an opportunistic and omnivorous species that primarily feeds on plant material. Recent studies have shown that Endo-β-1,4-glucanase and Endo-β-1,4-mannanase are expressed in the transcriptome of adult specimens, while juveniles are capable of digesting nutrients from purified cellulose in their diet. In organisms

Identification and Validation of Tissue-Specific Housekeeping Markers for the Amazon River Prawn <i>Macrobrachium amazonicum</i> (Heller, 1862). [PDF]

Genes (Basel)
Background/Objectives: The selection and validation of species-specific housekeeping genes (HKGs) have become increasingly common in functional genomics, with application of quantitative Polymerase Chain Reaction (qPCR) or cDNA-based qPCR (RT-qPCR). Despite the Macrobrachium amazonicum having RNA-seq studies available, there are still no data on the ...
