Selected coelomic fluid parameters of sterlet, Acipenser ruthenus L.: effects of light color and photoperiod

open access: yesArchives of Polish Fisheries, 2014
Light and color have effect physiological aspects of fish such as growth, the neuro-hormonal system, and reproduction. In the present study, the effects of light color and photoperiod on the levels of selected parameters of coelomic fluid (glucose, total
