The potential use of the parasites Crassicauda (Nematoda) and Nasitrema (Platyhelminthes) as biological tags and their role in the natural mortality of Common dolphins, Delphinus delphis, in the eastern north Pacific

This study surveys the incidence of the platyhelminth Nasitrema sp(p). and the nematode Crassicauda sp(p). in the air sinus and inner ear complex of the common dolphin, Delphinus delphis in the eastern North Pacific. Primary areas of investigation involve the potential use of these two parasites as natural biological tags in stock separation and their role in the natural mortality of free ranging populations. 1984 Contract no.
