ABSTRACT

Nauplii of Artemia salina have not been widely applied in rearing of commercial salmonids, much more often they have been used in rearing of larvae of other species, in particular cyprinids. The present study shows results of rearing of Atlantic salmon larvae and sea trout larvae with Artemia nauplii. The rearing was performed for 4 weeks in three groups: (1) fry fed with live nauplii of Artemia salina, (2) fry fed with mixed diet (live Artemia salina nauplii and commercial pellet diet for trout larvae and (3) only pellet diet. The rate of survival of both species in all groups representing different variants of feeding was very high, but in each variant the survival of Atlantic salmon was greater than that of sea trout. Larvae of Atlantic salmon and sea trout fed on mixed diet characterized by the best rate of survival and growth. In the last week of rearing the highest condition index was noted for the larvae of both species fed on mixed diet, similarly high condition index was found also for the Atlantic salmon fed on pellets. The results of this study shows that the use of live Artemia nauplii as a diet supplement brings satisfactory results in the whole period of rearing.

Key words: Atlantic salmon, sea trout, larval rearing, Artemia salina.
