Exploring the gut microbiota composition of Indian major carp, rohu (Labeo rohita), under diverse culture conditions.

Gut microbiota of freshwater carps are often investigated for their roles in nutrient absorption, enzyme activities and probiotic properties. However, little is known about core microbiota, assembly pattern and the environmental influence on the gut microbiota of the Indian major carp, rohu. The gut microbial composition of rohu reared in different culture conditions was analysed by 16S rRNA amplicon sequencing.

Nutrient budgets and effluent characteristics in giant freshwater prawn (Macrobrachium rosenbergii) culture ponds.

It is important to understand nutrient budgets of aquaculture practices for efficiency of input resources and to utilize all output nutrient sources. The aim of the present study was to develop a nutrient budget for giant freshwater prawn (Macrobrachium rosenbergii) culture ponds. The study was conducted in farmer's ponds (0.

Carbon, nitrogen, and phosphorus budget in scampi (Macrobrachium rosenbergii) culture ponds.

Experiments were conducted for the study of nutrient budget in ten farmer's ponds (0.2-0.5 ha) in Orissa, India with a mean water depth of 1.

Identification of MDP (muramyl dipeptide)-binding key domains in NOD2 (nucleotide-binding and oligomerization domain-2) receptor of Labeo rohita.

In lower eukaryotes-like fish, innate immunity contributed by various pattern recognition receptor (PRR) plays an essential role in protection against diseases. Nucleotide-binding and oligomerization domain (NOD)-2 is a cytoplasmic PRR that recognizes MDP (muramyl dipeptide) of the Gram positive and Gram negative bacteria as ligand and activates signalling to induce innate immunity. Hypothesizing a similar NOD2 signalling pathway of higher eukaryotes, the peripheral blood leucocytes (PBLs) of rohu (Labeo rohita) was stimulated with MDP.
