1
Assessed over a 4-wk breeding period following termination of the 16-wk feeding trial. Successful events = female released eggs; n = 32 total breeding events per diet.
2
Estimates are from the logistic component of zero-inflated negative binomial regression analysis and represent probability of a successful spawn relative to the reference group within each predictor variable. Significant P values (P < 0.05) represent differences from the reference group.
