Toxicity effects of multi-walled carbon nanotubes (MWCNTs) nanomaterial on the common carp (Cyprinus carpio L. 1758) in laboratory conditions.

Over the past decade, the usages of carbon nanotubes in various industries have been increased. Multi-walled carbon nanotubes (MWCNTs) are special form of carbon nanotubes which are used as nano-absorbents for various purposes of different industries due to their high surface to volume ratio. In aquatic environments these active nano-agents can easily absorb and accumulate in animal cells and tissues due to their tiny sizes and induce toxicity effects on bio-organisms mainly via pro-oxidants production.

Hematological, hepatic enzymes' activity and oxidative stress responses of gray mullet (Mugil cephalus) after sub-acute exposure to copper oxide.

Given the importance of assessing potential toxicity of heavy metals in valuable species of aquatic animals, the goal of the present research was to assess the sub-acute effects of copper oxide on hematological, enzymological, and oxidative stress responses of gray mullet to measure toxicity of copper oxide pollution in this significant fish. The median lethal concentration (LC) value of copper oxide to gray mullet was detected at 3.15 ± 0.

Camellia sinensis supplemented diet enhances the innate non-specific responses, haematological parameters and growth performance in Mugil cephalus against Photobacterium damselae.

This study evaluated the effect of dietary supplementation of Camellia sinensis leaf-extract on non-specific immune responses and disease resistance of Mugil cephalus fingerling against P. damselae. Fish were fed with 0 (unsupplemented), 50, 100 and 200 mg/kg of green tea extract (GTE) supplemented diets.
