Is Anisakis simplex s.l. a biological marker for stock identification of Strangomera bentincki from Chile?

The absence of the larval Anisakis simplex s. l. in samples from central Chile but heavy infections in fish from southern localities suggest the existence of two stocks of Strangomera bentincki, one closely associated with the central coast of Chile (landing port San Antonio and Talcahuano, c. 33° 30′ S–36° 40′ S) and the other associated with southern Chile (landing port Puerto Montt, c. 41° 30′ S). Results confirm the usefulness of metazoan parasites, like A. simplex s. l. as biological markers.
