Predators use cues associated with their prey to assess prey quality and to avoid consuming poisonous prey. Considerable attention has been given to predators' use of aposematic cues to assess prey quality, but little is known about predators that eavesdrop on prey cues that are not intended for them. Here we investigate the prey-cue/prey-quality associations of a predator that eavesdrops on th...

An experiment was carried out to evaluate the effects of different amounts supplementary feeds on growth and production fishes in polyculture where four species such as rui (Labeo rohita), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio) tilapia (Oreochromis niloticus) were cultured 6 ponds under three treatments, each with two replications. Eighty fish per decimal stocked along stocki...

The present study deals with the impact of differential quantity iron oxide nanoparticles incorporated feed on growth, biochemical and haematological characteristics Mrigal. Iron were synthesised characterized by using 5 UV-Vis spectroscopy(UV-Vis ) , Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDAX), Diffraction (XRD), Fourier Transform Infrared (FT-IR) andVibrati...
