Effects of Maternally Transferred Egg Selenium on Embryo‐Larval Survival, Growth, and Development in Arctic Grayling ( Thymallus arcticus)
Abstract Selenium (Se) toxicity to fish is primarily manifested via maternal transfer to the eggs, which may result in adverse effects on larval survival and development. The present study assessed the effects of egg Se concentrations derived via maternal transfer on early life–stage development, su...
