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

Anthropogenic sources increase freshwater salinity and produce differences in constituent
ions compared with natural waters. Moreover, ions differ in physiological roles and …

Euryhaline fishes live in a wide salinity range from freshwater to seawater and hypersaline
environments. Euryhaline fishes such as salmon, eels, and tilapia are economically …

Extreme water temperatures related to global climate change represent a significant
challenge in terms of fish welfare and aquaculture productivity. Understanding the effect of …

The structure of the gut barrier and luminal chemistry in non-mammalian vertebrates and
invertebrates has been given little attention with respect to the dietary uptake of engineered …

Unprecedented shifts in temperature and precipitation patterns in recent decades place
multiple abiotic stressors on the fish. In teleosts, metabolic, osmoregulatory, and molecular …

Fishes are the first vertebrates, descendents of the early chordates* that evolved from
marine, deuterostome invertebrates. The extant lancelets and tunicates both marine and …

An area of emerging importance is the role that the diet can play in alleviating the demands
for ion uptake in fish living in a freshwater environment, by providing a highly concentrated …

We investigated the potential acid–base and nitrogenous waste excretion challenges
created by voluntary feeding in freshwater rainbow trout, with particular focus on the …

A comparative study of gastric evacuation rates (GERs) and digesta content, moisture and
pH values along the gastrointestinal tract was performed between gilthead sea bream and …
