Figure 6 in Discrimination between six commercially relevant and ecologically diverse fish species across the Gulf of Tunis using fatty acid composition and otolith shape analyses

Figure 6. Principal component analysis (PCA) graph (biplot) showing the consistency between the variation in the otoliths shape (OS) and the variation in fatty acid composition between and within males (M) and females (F) of the six species collected from the five stations in the Gulf of Tunis, Tunisia.
