Appendix F. Univariate analyses of density, legal-sized target fishes.

TABLE F1. Univariate analyses of density, legal-sized target fishes. Full three-factor ANOVAs when data permit. Absent sufficient data for full model, or upon significant interaction involving reserve and site: planned pairwise comparisons of reserve effect at individual sites with sufficient data. Significant P values (<0.05) are in boldface type.
