The article discusses advances in osmoregulation and excretion with emphasis on how
multicellular animals in different osmotic environments regulate their milieu intérieur …

For teleost fish living in seawater, drinking the surrounding medium is necessary to avoid
dehydration. This is a key component of their osmoregulatory strategy presenting the …

Shallow or near-shore environments, such as ponds, estuaries and intertidal zones, are
among the most physiologically challenging of all aquatic settings. Animals inhabiting these …

The aim of this investigation was to isolate and identify Bacillus species isolated from the
internal microbiota of Red sea stingrays as potential probiotics. An initial assay on the ability …

The killifish Fundulus heteroclitus is an estuarine species with broad physiological plasticity,
enabling acclimation to diverse stressors. Previous work suggests that freshwater …

Maintaining normal pH levels in the body fluids is essential for homeostasis and represents
one of the most tightly regulated physiological processes among vertebrates. Fish are …

The acid–base relevant molecules carbon dioxide (CO2), protons (H+), and bicarbonate
(HCO3−) are substrates and end products of some of the most essential physiological …

A better knowledge of daily digestive function may help to improve the feeding efficiency in
farmed fish species. In this study, daily expression profiles of key genes related to the …

The physiological processes underlying the post-prandial rise in metabolic rate, most
commonly known as the 'specific dynamic action'(SDA), remain debated and controversial …

For nearly a century, researchers have studied ammonia production and excretion in teleost
fish. Stemming from past investigations a body of knowledge now exists on various aspects …
