Abstract

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 18to 32C) 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 18C, 20 days at 24C and 15 days at 30C. The thermal constant was 3566 day-degrees and the developmental zero value was 6.31.9C.
