Fish have evolved a biological clock to cope with environmental cycles, so they display
circadian rhythms in most physiological functions including stress response. Photoperiodic …

Tanks offer significant flexibility for aquaculture production. When in an optimally operated
water reuse configuration, they enable farming of most, if not all species of fish, in …

Fish social behavior can be affected by artificial environments, particularly by factors that act
upon species that show aggressive behavior to set social rank hierarchy. Although …

Ubiquitous in non-mammalian vertebrates, extra-retinal photoreceptors (ERPs) have been
linked to an array of physiological, metabolic, behavioral, and morphological changes …

It is well known that fish vision and spectrum perception are strongly related to each species
natural habitat and living ethology. Recent research data clearly indicate that light spectrum …

In aquaculture, fish behaviour monitoring and analysis can provide the information required
to guide daily feeding, schedule making and disease diagnosis. Technology such as …

As important environmental factors, the light spectra and tank colours have not received
sufficient attention. Most fishes have the ability to perceive environment, distinguish colours …

Nile tilapia fish were individually reared under similar light levels for 8 weeks under five
colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (∼ …

The sapphire devil, Chrysiptera cyanea, were reared for 45days during the non-reproductive
season (September) under LD14: 10 at four different wavelengths produced by light emitting …

We investigated the effects of environmental light colors (blue, yellow and white) on the
stress responses (measured by changes in ventilatory frequency–VF) of Nile tilapia to …
