The parent generation of the viviparous blenny, Zoarces viviparus L., were exposed to phytosterols (a) from oogenesis to parturition and (b) from breeding to parturition. The experiments were performed under laboratory conditions in a test unit suppl

Maturing lake trout ( Salmo trutta lacustris ) of both sexes were exposed to 10 and 20 μg/liter phytosterols, mainly s-sitosterol, for 4.5 months prior to spawning. Eggs from preexposed females were artificially fertilized with milt from preexposed
