Fishes are exposed to natural and anthropogenic changes in their environment, which can
have major effects on their behaviour and their physiology, including feeding behaviour …

This review discusses environmental colour impact on such vital processes of lower aquatic
vertebrates (amphibian and fish), as development, growth, consumption of food and its …

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 …

TL= 56.2±2.7 mm and W= 1.66±0.4 g, and big with TL= 71.0±3.2 mm and W= 2.95±0.65 g) …

An 8 weeks trial was performed to test the effects of light spectra [full-spectrum, violet (405
nm), blue (470 nm), cyan (500 nm), green (525 nm), yellow (570 nm), and red (625 nm)] on …

This study investigated the daily variations of stress markers namely plasma cortisol and
glucose and some humoral innate immune markers, including peroxidase, lysozyme and …

Light-emitting diodes (LEDs) have gained increasing popularity in fish farming because
certain wavelengths of light may promote the growth and innate immune system of fish. In …

Melatonin is considered as the time-keeping hormone acting on important physiological
functions of teleosts. While the influence of melatonin on reproduction and development is …

Juvenile pikeperch (Sander lucioperca) were reared for 58days according to one of the
following feeding regimes: control (fed once every day); 1+ 1 (fed every other day); 1+ 3 (one …

This study aimed to evaluate the effects of different monochromatic LED light colors (blue
“BL”, red “RL”, green “GL” and white “WL”) in addition to natural day light (NL) on the growth …
