ABSTRACT. The survival and growth rate of Atlantic sturgeon, Acipenser oxyrhynchus oxyrhynchus Mitchill, eggs and fry were tested in a recirculation system and in the Drwęca River on mineral substrate. In comparison to standard methods of egg incubation and fry rearing, survival was lower and the growth rate was higher. The survival rate of eggs incubated in the Drwęca River was comparable to natural survival rates noted in Canadian spawning grounds.
Keywords: Atlantic sturgeon, Acipenser oxyrhynchus oxyrhynchus, recirculation system, Drwęca River
