Artificial hatching substrate in the mass rearing of larval Atlantic salmon (Salmo salar)
Eggs from individual Atlantic salmon (Salmo salar) were hatched in a Californian hatching system with and without an astro-turf artificial substrate and growth during the first 200 days following hatching was investigated. The astro-turf promoted yolk absorption rate, yolk conversion efficiency and...
