Table 1 Summary information for all Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and American plaice
(Hippoglossoides platessoides) sampled on Georges Bank (GB) and in the Gulf of Maine (GUM).
Finally, we exposed American plaice to larval Neophasis sp.
Further, to obtain the adult stages required for species identification of larval parasites from the gonad and digestive gland, we attempted to infect American plaice, Hippoglossoides platessoides, which is a host for several trematodes (Bray and Gibson, 1991).
We found no adult Neophasis in the digestive systems of the American plaice (Hippoglossoides platessoides) that we had attempted to infect, and thus we could not identify the species of Neophasis.
One adult digenetic trematode observed in the stomach of about 12% of the whelks was identified as Steringophorus furciger, a parasite previously reported from the stomach of whelks in the Mingan Islands by Hamel (1989) and from the stomach of American plaice in the Gulf of St.
American plaice (Hippoglossoides platessoides) are found in Northwest Atlantic waters along the continental shelf and upper continental slope from west Greenland to Rhode Island, favoring intermediate depths (90-250 m), cold waters (<0-1.
Although there have been no prior attempts to use parasite assemblages in describing the stock structure of American plaice, parasitological surveys of plaice in the Northwest Atlantic have identified a number of potential parasite tags.
American plaice, 31 to 40 cm in total length, were collected from two locations in the southern Gulf of St.
Data on the biology of American plaice from the southern bank of Newfoundland and from the Cape Breton shelf.
Vitellogenesis in American plaice was seen to begin soon after spawning (Zamarro, 1992), as with Rikuzen sole.
As American plaice in the tail of the Grand Bank of Newfoundland become older, the number of eggs produced by females decreased (Horwood et al.
Gross and histological observations of ovarian development and related condition changes in American plaice.
