The proximate, mineral composition and amino acid profile of the body parts of Macrobrachium vollenhovenii (African river prawn) and Tympanotonus fuscatus (tropical periwinkle) were determined. The length and weight of the prawns varied from 15cm to 17.6cm and 72.76g to 130.65g respectively while the length and weight of the periwinkles varied from 22.72mm to 54.72mm and 1.53g to 7.59g respecti...

Background Dystrophin, an essential protein functional in the maintenance of muscle structural integrity is known to be responsible for muscle deterioration during white spot syndrome virus (WSSV) infection among prawn species. Previous studies have shown the upregulation of dystrophin protein in Macrobrachium rosenbergii (the giant freshwater prawn) upon white spot syndrome virus (WSSV) infect...

ABSTRACT Knowledge about the diet of a given species is essential to provide information on growth and maintenance populations in natural environment. Macrobrachium brasiliense (Heller, 1862) freshwater prawn widely distributed Brazil, being frequent aquatic environments inserted Cerrado biome. The aim this study was evaluate population M. brasiliense, comparing consumed food items according se...

Breeding programs in oriental river prawn populations would benefit from a knowledge of heritabilities for growth-related traits to assess their potential genetic improvement. This study reports the results heritability estimation and evaluation epistatic interactions (Macrobrachium nipponense). The showed that estimates (h2) were low medium magnitude, ranging between 0.10 (±0.02) 0.22 (±0.01) ...
