The Life Cycle and Larval Development of Echinorhynchus lageniformis Ekbaum, 1938 (Acanthocephala: Echinorhynchidae)

Use of parasite tags in delineating stocks of white hake (Urophycis tenuis) from the southern Gulf of St. Lawrence and Cape Breton Shelf

“…For example, E. gadi infecting a relict pop- ulation of Barents Sea cod are recruited in the fall, and die off in late summer and early fall of the following year (Kulachkova and Timofeyeva, 1993). According to Olson and Pratt (1971), E. lageniformis also live for about a year in the intestines of starry flounder (Platichthys stellatus) in the coastal waters of Oregon.…”

Ecology of marine parasites

“…They show that even between species of one family there may be great differences in maturation time and life span. The acanthocephalan Echinorhynchus lageniformis lives for about one year in the final host, the starry flounder Platlchthy$ stellatu$, since older fish lose the parasites (Olson & Pratt, 1971). Among the leeches, the species Johanssonia arctica lives Table 9.…”

Use of parasites as tags in delineating stocks of Atlantic cod (Gadus morhua) from the southern Gulf of St. Lawrence and the Cape Breton Shelf

“…E. gadi infecting a relict population of Barents Sea cod, for example, are recruited in the fall and die off in late summer and early fall of the following year (Kulachkova and Timofeyeva, 1993). Similarly, E. lageniformis survive for about a year in the intestines of starry flounder (Platichthys stellatus) in the coastal waters of Oregon (Olson and Pratt, 1971). In any event, parasites need not be long-lived in order to be suitable as markers, as there are numerous precedents for use of enteric helminths as markers in studies of host stock structure and identification (Williams et al, 1992).…”
