First feeding strategy for hatchery produced beluga sturgeon, Huso huso larvae
Co-feeding of fish larvae with live food and formulated diet has been at the focus of fish nutritionists since last decade. In this study we tried to refine the feeding practices of great beluga sturgeon (Huso huso) larvae using different combinations of newly hatched Artemia urmiana nauplii and tro...

Co-feeding of fish larvae with live food and formulated diet has been at the focus of fish nutritionists since last decade.
