Relationship between embryo survival and egg carotenoid content. (a) Mean embryo survival until hatching per dam (means of maternal half‐sib groups) versus carotenoid contents of unfertilized eggs (log₁₀‐transformed means per dam in μg/ml), and (b) treatment‐induced mortality; for example, mean survival per dam in sham‐treated controls minus mean survival in highest stress treatment (nutrient broth at 1:500) versus reduction of carotenoid content from day of fertilization until 14 days after treatment (in μg/ml). Astaxanthin: black symbols and nonhatched regression line; zeaxanthin: gray symbols and hatched regression line, lutein: open symbols and dotted regression line. See Tables 2 and 3 for statistics. Regression lines illustrate the direction of significant effects
