Toxicity Statistics

Stats Suggestions Needed! I am analyzing results of Percent Survival and Growth (Weight) bioassays. These samples are grouped into different strata based on location. I need to compare the means of these strata groups to each other and control samples.

For Growth (Weight) Results...go towards ANOVA to compare means (with different sample sizes).

For Percent Survival...not sure what direction to go in other than non-parametric. Since the control sample would be assumed as 100% survival, would I need to compare my other samples to that?
