As increasing amounts of novel raw materials are used in aquafeed production, it is
important to measure their quality against existing ingredients and their effects upon …

Circadian rhythmicity in behaviour and metabolism is a ubiquitous phenomenon in biology,
documented in such diverse species as unicellular organisms, plants, invertebrates, and …

In many fish species, some individuals arediurnal while others are nocturnal. Sometimes,
the same individual can be diurnal at first andthen switch to nocturnalism, or vice-versa. This …

There is no information on whether the daily foraging movements of fish shoals are the result
of chance, the collective will of all shoalmates, or the leadership of a few individuals. This …

As part of an effort to characterize the circadian system of the zebrafish, we examined the
circadian regulation of locomotor activity in adult males and females. Gross locomotor …

Feeding cycles entrain biological rhythms, which enables animals to anticipate feeding
times and so maximizes food utilization. In this article the effect of mealtime on locomotor …

Repetitive aquaculture-related protocols may act as cyclic stressors that induce chronic
stress in cultured fish. The sea bass is particularly sensitive to stressful conditions and the …

We studied the effect of automatic-feeding (A), ad libitum demand-feeding (D) and time-
restricted demand-feeding (RD) on the feeding rhythm and growth performance of European …

A general property of living systems is that they function under conditions that are far from
thermodynamic equilibrium. Each living organism must be considered as a different system …

The effect of light–dark (LD) cycle and food availability was tested on the demand-feeding
rhythm of single and groups of rainbow trout and European catfish. Under LD and free food …
