Abstract:
Two parthenogenetic populations from Çamalti (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 Çamalti
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 Çamalti in survival at 25 and 30°C,
neither of the strains exhibited good performance at high temperature. The
optimum salinity for the Çamalti population was 80 g l-1, while the Kalloni population appeared to perform
well at 120 g l-1.
The fatty acid composition of Çamalti cysts was found to be of good quality
for use in aquaculture, especially in feeding larvae of marine species.
