Abstract
Two parthenogenetic populations from Camalti(Izmir, Turkey) and Kalloni (Lesbos, Greece) were evaluated for their tolerance and fitness at different salinities and temperatures under laboratory conditions aiming to compare salinity and temperature effects upon special characteristics of the two Artemia strains, such as survival, growth rate, age of maturity and morphometry. Furthermore, biometry, hatching characteristics and fatty acid profile of Camalti cysts were evaluated for potential use in aquaculture. This evaluation revealed that both populations showed significant differences in their response to different temperatures and salinity. Although significant differences occurred between Kalloni and Camalti in survival at 25 and 30°C, neither of the strains exhibited good performance at high temperature. The optimum salinity for the Camalti population was 80 g l−1, while the Kalloni population appeared to perform well at 120 g l−1. The fatty acid composition of Camalti cysts was found to be of good quality for use in aquaculture, especially in feeding larvae of marine species.
