The importance of salt and water absorption from the food by the gastrointestinal tract and its
impact on iono-and osmoregulation have been largely overlooked by fish physiologists. The …

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

Both Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout) have a long history
of translocation and culture and a wide knowledge base exists. O. mykiss is being …

The Asian sea bass is a carnivorous, euryhaline species originating in seawater. It is
currently being reared under intensive conditions in fresh and brackish water recirculating …

This study aims to examine ionoregulatory parameters during exercise and cortisol elevation
in common carp fed different food rations. Fish subjected to two different feeding regimes …

Cataracts leading to visual disturbance or blindness in farmed Atlantic salmon (Salmo salar

The transfer to seawater (SW) represents a critical stage in the production of Atlantic salmon.
The success of the transfer links with the optimal development of hypo-osmoregulatory …

Abiotic factors like salinity are relevant to survival of pelagic fishes of the San Francisco Bay
Estuary. We tested the effects of 4 parts per thousand (ppt) salinity increases on Delta Smelt …

Parr in freshwater were given supplementary betaine (1.5%) NaCl (10%) or both from 27
September to 21 October, then directly transferred to seawater. Dietary betaine resulted in a …
