Performance of Macrobrachium rosenbergii broodstock fed diets with different fatty acid composition
Results demonstrate that feeding M. rosenbergii broodstock with high levels of 18:2 n −6 and n −3 HUFA improved fecundity, egg hatchability, and the overall quality of the larvae. Expand
Effect of practical diets with different protein levels on the performance of Farfantepenaeus paulensis juveniles nursed in a zero exchange suspended microbial flocs intensive system.
Results show that, when rearing is carried out in a suspended microbial flocs system, dietary CP levels can be kept at 350 g kg−1 and confirm that microbial-based systems allow shrimp culture without compromising the surrounding environment and shows the possible reduction of production costs and fish meal dependence.

Biofloc technology application as a food source in a limited water exchange nursery system for pink shrimp Farfantepenaeus brasiliensis (Latreille, 1817)
Favourable nutritional quality of bio£oc wasmed, and enhanced growth and production of F. brasiliensis PL in bio £oc systems was enhanced. Expand

An alkaline peptidase was purified from the viscera of the silver mojarra in a three-step process: heat treatment, ammonium sulphate fractionation and molecular exclusion chromatography, with final specific activity 86-fold higher than the enzyme extract and yield of 22.1%. Expand
Superintensive Culture of White Shrimp, Litopenaeus vannamei, in a Biofloc Technology System in Southern Brazil at Different Stocking Densities
The use of greenhouse-enclosed shrimp biofloc culture rearing system (BFT systems) is a technology that makes it possible to increase the culture period in higher latitudes by reducing water exchange and minimizing heat loss. Expand
Nursery of the pink shrimp Farfantepenaeus paulensis in cages with artificial substrates: Biofilm composition and shrimp performance
At the end of the trial shrimp reared in the presence of artificial substrates achieved significant higher survival, growth and total biomass (p), and the composition of the diatom community suffered significant changes after shrimp introduction to the cages. Expand
Variations in lipid classes and fatty acid content in tissues of wild Macrobrachium rosenbergii (de Man) females during maturation
The lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves, mainly due to an increase of TG and sterols. Expand
Effect of biofloc technology (BFT) on the early postlarval stage of pink shrimp Farfantepenaeus paulensis: growth performance, floc composition and salinity stress tolerance

The continuous availability of bioflocs had a significant effect on growth and survival of F. paulensis postlarvae cultured in BFT nursery systems. Expand
Ovarian maturation of wild Farfantepenaeus paulensis in relation to histological and visual changes
The observation of visual features coupled with histological characteristics was found to represent a reliable procedure to evaluate the ovarian maturation of F. paulensis. Expand
Reproductive performance of different sized wild and pond-reared Penaeus paulensis females.
The number of eggs and nauplii per spawning event were not significantly different between experimental groups, but due to their higher spawning frequency, small wild females outperformed medium and large females and Optimum size for the maturation of wild P. paulensis females was estimated to be from 30 to 60 g.
