Most fish studied to date efficiently compensate for a hypercapnic acid-base disturbance;
however, many recent studies examining the effects of ocean acidification on fish have …

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

Fishes have evolved three fundamental strategies in handling the composition of the
extracellular fluid (plasma, lymph, and interstitial fluid): osmoconformity, where fish plasma …

Publisher Summary The main function of the alimentary tract of any animal is the acquisition
of food with subsequent assimilation of vital nutrients. The natural diet of fishes varies …

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

Oceanic production of calcium carbonate is conventionally attributed to marine plankton
(coccolithophores and foraminifera). Here we report that marine fish produce precipitated …

Despite early reports, dating back three quarters of a century, of high total CO2
concentrations in the intestinal fluids of marine teleost fishes, only the past decade has …

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 …

Fish living in marine and freshwater environments face contrasting challenges in terms of
maintaining salt and water balance. The present chapter summarizes and reviews much of …

Fish aquaculture facilities strive to maintain abiotic conditions that optimise somatic growth.
Two physiological systems that are critically linked to environmental abiotic factors are ion …
