Global climate change due to anthropogenic activities affects the dynamics of aquatic
communities by altering the adaptive capacities of their inhabitants. Analysis of blood …

Freezing, dehydration, salinity variations, hypoxia or anoxia are some of the environmental
constraints that many organisms must frequently endure. Organisms adapted to these …

Nowadays, depletion of oxygen or hypoxia has become a real concerning problem
worldwide in freshwater, marine, and estuarine ecosystems and very often co-occurs with …

Nitrite is endogenously produced as an oxidative metabolite of nitric oxide, but it also
functions as a NO donor that can be activated by a number of cellular proteins under hypoxic …

The effects of salinity on growth and parameters related to osmoregulation and energy
turnover were evaluated in juvenile pompano Trachinotus marginatus. In a first experiment …

The present study determined the blood plasma osmolality and oxygen consumption of the
perch Perca fluviatilis at different salinities (0, 10 and 15) and temperatures (5, 10 and 20° …

Stress-induced by low water-dissolved oxygen (DO) negatively influences the overall fish
performances. Hybrid yellow catfish (Pelteobagrus fulvidraco× P. vachelli) was subjected to …

Nitric oxide (NO), produced by nitric oxide synthases (NOS enzymes), regulates multiple
physiological functions in animals. NO exerts its effects by binding to iron (Fe) of heme …

Experiments were performed to evaluate the effects of temperature-induced changes in
functional gill lamellar surface area on the distribution of ionocytes and branchial chloride …

This study analyzed the chemical composition and anesthetic potential of essential oil (EO)
of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO …
