In order to explore the effects of probiotics on water quality, growth performance, nonspecific immunity, digestion, and intestinal flora Macrobrachium rosenbergii in biofloc culture system, three groups (six replicates each group) were set up divided into no bacteria (control group, Con), Bacillus subtilis (BS), effective microorganisms (EM) current experiment. After dissolution water, carbon ...

The gene encoding the capsid protein of Macrobrachium rosenbergii nodavirus (MrNV) was cloned into pGEX-6P-1 expression vector and then transformed into the Escherichia coli strain BL21. After induction, capsid protein-glutathione-S-transferase (GST-MrNV; 64 kDa) was produced. The recombinant protein was separated using SDS-PAGE, excised from the gel, electro-eluted and then used for immunizati...

In Crustacea, an early evolutionary group (∼50 000 species) inhabiting most ecological niches, sex differentiation is regulated by a male-specific androgenic gland (AG). The identification of AG-specific insulin-like factors (IAGs) and genomic sex markers offers an opportunity for a deeper understanding of the sexual differentiation mechanism in crustaceans and other arthropods. Here, we report...

Phylogenetic analysis of representatives from 18 wild populations of the giant freshwater prawn, Macrobrachium rosenbergii, utilising a fragment of the 16S rRNA mitochondrial gene, identified two major reciprocally monophyletic clades either side of a well-known biogeographic barrier, Huxley's line. The level of divergence between the two clades (maximum 6.2%) far exceeds divergence levels with...

Limitation of food availability (starvation) is known to influence the reproductive ability of animals. Autophagy is a lysosomal driven degradation process that protects the cell under metabolic stress conditions, such as during nutrient shortage. Whether, and how starvation-induced autophagy impacts on the maturation and function of reproductive organs in animals are still open questions. In t...

Macrobrachium tenellum and M. americanum are common freshwater prawns from the Americas' tropical subtropical Pacific continental side. They have different biological attributes currently threatened by human impact on their ecosystems. Both species provide quality products for consumption intensively exploited without proper management. This study analyzes, discusses, compares available informa...

The giant freshwater prawn Macrobrachium spinipes (Schenkel, 1902) is recorded from Taiwan for the first time and extends the distribution of the species to north of the Tropic of Cancer. The Taiwanese specimens differ slightly from material from Indonesian Papua in the density of the spination of the adult second pereipods, the relative length of the ridge of the posterior submedian plate of t...

The effect of formalin on the organoleptic parameters, biochemical composition and storage quality of iced and frozen stored giant freshwater prawns (Macrobrachium rosenbergii) was investigated. The organoleptic characters such as appearance, textural condition, colour, odour of both formalin added and non-added prawns were evaluated. The quality of non-added prawns was judged good up to first ...

This study aimed at detecting possible patterns in the relationship between Anisosmotic Extracellular Regulation (AER) and Isosmotic Intracellular Regulation (IIR) in crustaceans and teleost fish from different habitats and evolutionary histories in fresh water (FW), thus different osmoregulatory capabilities, and degrees of euryhalinity. Crustaceans used were the hololimnetic FW Aegla schmitti...
