TABLE 3.

Multi‐variable PERMANOVA (Adonis) analysis for Blue Catfish diets. We investigated differences between collection dates, life stage (juvenile or adult), size of fish (measured by 100 mm increments), and collection site. The single variable of collection date contributed the most significantly to variation in fish diet. R ² scores indicate that collection date in conjunction with collection site further contributes to differences in diet. COI sequences suggest that life stage and size of fish also contribute to diet variation
