The goal of the experiment was to determine if incubation temperature effected fish growth and survival 31 days after feeding. The broodyear 2011 fish were placed into the experimental incubation treatments just after they had reached the eyed egg stage in late 2011. The eyed eggs and yolk sac fry were then either incubated in (6.5 degree C) or unchilled (9-10 degree C) water until they reached the swimup stage in early 2012. Although incubation temperature was the primary treatment variable of interest, the experimental design included the portion of the run when the eggs were spawned (= time when the eggs were place into the treatment) and hatchery source as secondary treatment variables of interest. The response variables of interest were average length in mm, weight in grams, and percent survival of fry in each replicate tanks 31 days after they swamup.
