For the period 1999–2003, diet composition, diet similarity, and major predator–prey interactions between the 15 most abundant demersal and pelagic fishes (N = 12,163 stomachs) were described for Northumberland Strait - a semienclosed, marine, co

To compare the roles of American lobster Homarus americanus and Atlantic rock crab Cancer irroratus in the food web processes of a coastal ecosystem, distribution, abundance, stomach contents, diet overlap, and occurrence in stomachs of predators wer

Windowpanes Scophthalmus aquosus were collected during demersal trawl surveys in Northumberland Strait in the southern Gulf of St. Lawrence, Canada, during July and August 2001–2012. Abundance indices showed relatively little variation between year

Abundances of Atlantic cod Gadus morhua and white hake Urophycis tenuis have dropped to historically low levels in the southern Gulf of St. Lawrence. Stomach samples were collected during late summer 2001 and 2002 to compare ontogenetic diet patterns

Approximately 73 000 Atlantic rock crab (Cancer irroratus) were captured in coastal waters and transferred to an estuarine mussel aquaculture site in Prince Edward Island, Canada, in an effort to control overgrowth by the invasive tunicate Ciona inte

Atlantic cod Gadus morhua stomach contents (n = 30 973, including 28 377 non-empty stomachs) and morphometric measurements on live snow crab Chionoecetes opilio and cod were examined to assess the predator-prey relationship between these 2 species. T

Mass-balance models, using inverse methodology, were applied to the southern Gulf of St. Lawrence for the mid-1980s and the mid-1990s to describe ecosystem structure, trophic group interactions, and the effects of fishing and predation on the ecosyst

The lady crab (Ovalipes ocellatus) is one of the most common native species of swimming crab (Portunidae) of the Atlantic Coast of North America but most populations occur south of Cape Cod, Massachusetts. There is a disjunct population in Northumber

Demersal fishes are widely thought to be an important source of natural mortality for juvenile American lobster Homarus americanus. There were no significant relationships between abundance indices of American lobster and the dominant demersal fish s
