Metazoan parasite infection in the swordfish, Xiphias gladius, from the Mediterranean Sea and comparison with Atlantic populations: implications for its stock characterization

Open Access

Table 4.

Kruskal-Wallis ANOVA (H) and chi-square (χ²) pairwise tests of mean abundance (A) and prevalence (P) values of the infection by the selected parasite taxa of X. gladius from the Mediterranean Sea (areas: CTS, STS, IOS) versus the Atlantic Ocean (areas: NW, CN, CS, ET, TEQ). CTS, STS, IOS: data from the present study, TEQ: data from [27] NW, CN, CS, ET: data from [28]. Ab, Absent in both areas; **P < 0.01; *P < 0.05; NS = not significant, P > 0.05. Parasites are listed in alphabetical order.
