Predicting the impacts of freshwater-flow alterations on prawn (Penaeus merguiensis) catches

, 2019
Modification of freshwater flow regimes can impact estuarine ecosystems at the receiving end of these flows. This is particularly true in tropical areas, such as the wet-dry tropics, where major freshwater flows in the wet season may result in prolonged ...

Sex reversal and the androgenic gland (AG) in Macrobrachium rosenbergii: A review

Aquaculture and Fisheries, 2020
The male giant freshwater prawn (Macrobrachium rosenbergii) generally exhibit faster growth rates compared to females of similar age. Consequently, the practice of culturing monosex (all-male) prawn can increase both the production yield and income ...

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Biofloc culture system shapes the structure and function of environmental and intestinal bacterial communities in the river prawn Cryphiops caementarius

Aquaculture Reports
Biofloc technology (BFT) has emerged as a sustainable method for prawn cultivation, particularly for regions with limited freshwater resources. The freshwater prawn Cryphiops caementarius exhibit improved survival and growth rates when cultivated using ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Effect of fenitrothion on reproduction of the freshwater prawn Macrobrachium lamerrii

Ecotoxicology and Environmental Safety, 1986
Acute and toxic effects of fenitrothion on eggs and larvae of Macrobrachium lamerrii have been studied. The hatching success of the eggs is not affected when berried females are exposed to fenitrothion. No drastic changes in egg production are seen at sublethal levels, while at higher concentrations females abort their eggs.
