Probiotic Strain Lactobacillus plantarum GCLP4 Derived From the Gut of Ctenopharyngodon idella Modulates Growth, Digestive Enzymes and Immune-Biochemical Parameters of Labeo rohita Fingerlings.

The present study was carried out to isolate, identify, and characterize bacterial probiotic strain from the gut of Ctenopharyngodon idella (Grass carp) and then to study its effect on growth, digestive enzymes and immunity of Labeo rohita fingerlings. A total of 6 gram-positive bacteria belonging to the genus Lactobacillus spp. (3), Bacillus spp.

Physio-metabolic alterations in Labeo rohita (Hamilton, 1822) and native predator Chitala chitala (Hamilton, 1822) in presence of an invasive species Piractus brachypomus (G. Cuvier, 1818).

A 60 days study was conducted to evaluate the physiological response of indigenous species Labeo rohita (LR) and indigenous predator Chitala chitala (CC) in presence of an invasive species Piaractus brachypomus (PB). Two treatment groups as LR + PB (T1) and LR + PB + CC (T2) with individual control groups as TLR, TPB and TCC were designed in triplicates. Fingerlings of LR, PB and CC were randomly distributed into 15 circular tanks with a stocking ratio of 1:1 and 1:1:0.

Assessment of microplastic contamination in the gastrointestinal tracts of indigenous fishes from north eastern hill regions of Bhogdoi, a tributary of River Brahmaputra, India.

Microplastic (MP) pollution in freshwater environments has drawn considerable attention over the decades due to the risk posed by MPs to the aquatic fauna and human health. In this study, the occurrence of MPs was assessed from the gastrointestinal tracts (GIT) of indigenous fishes from Bhogdoi River, a tributary of River Brahmaputra, northeast hill region, Assam, India. All the fish species (n = 180) analysed showed 100% occurrence of MPs sampled from three stations of River Bhogdoi.
