The regulation of food intake in fish is a complex process carried out through several
different mechanisms in the central nervous system (CNS) with hypothalamus being the …

Assessing the activity of digestive enzymes is a common procedure in many biological,
physiological and nutritional studies. After reviewing the available literature on fish digestive …

Acoustic telemetry techniques are very useful tools to monitor in detail the swimming
behavior and spatial use of fish in artificial rearing environments at individual and group …

Increased aquaculture production has raised concerns about managing protocols to
safeguard the welfare of farmed fish, as consumers demand responsible aquaculture …

Two different modes for regulation of stomach acid secretion have been described in
vertebrates. Some species exhibit a continuous acid secretion maintaining a low gastric pH …

Daily light and feeding cycles act as powerful synchronizers of circadian rhythmicity.
Ultimately, these external cues entrain the expression of clock genes, which generate daily …

While most animals have received increasing attention for their welfare, consideration for
fish welfare has started more recently, particularly since the recognition that fish have …

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 …

In the context of Mediterranean aquaculture many efforts have been made in terms of
reducing marine-derived ingredients in aquafeed formulation. On the other hand, little …

Many fish experience daily cycles of hypoxia in the wild, but the physiological strategies for
coping with intermittent hypoxia are poorly understood. We examined how killifish adjust O2 …
