Key words: Artemia, growth, survival, temperature effects, thermal constant
The thermal constant, growth and survival of Artemia from Tuz Lake, Central Anatolia, were
evaluated under laboratory conditions. Artemia nauplii (24-48 hours after hatching) were stocked
into a 60 ppt salinity medium which contained Dunaliella and Oocystis. The Artemia were cultured
at one of eight temperatures (2-degree intervals from 18°to 32°C) for 30 days, in two replicates.
The animals grew faster but survival was lower as the temperature increased. Complete
development from the nauplius stage to the adult stage required 30 days at 18°C, 20 days at
24°C and 15 days at 30°C. The thermal constant was 356±6 day-degrees and the developmental
zero value was 6.3±1.9°C.
