  • Description:
    "Silver hake, Merluccius bilinearis (Figure 1), are distributed on the continental shelf of the northwest Atlantic Ocean from the Gulf of St. Lawrence and the southern edge of the Grand Banks, Newfoundland, Canada (Leim and Scott 1966; Brodziak 2001) to Cape Fear, North Carolina (Karnella 1973) and perhaps as far south as South Carolina (Bolles and Begg 2000). Their presence in the deep waters off the Bahamas reported by Norman (1939) was probably a misidentification of Merluccius albidus, the offshore hake. In general, silver hake are abundant from Nova Scotia to New Jersey. Silver hake are slender, fast swimming gadids with well-developed gill rakers and eyes, strong teeth, and pike-like jaws (Garrison and Link 2000). These demersal fish are often found in dense schools associated with specific hydrographic conditions, prey concentrations, and spawning requirements. Silver hake are distributed from shallow waters to depths greater than 400 m (Dery 1988; Bolles and Begg 2000). Scotian Shelf silver hake prefer warm bottom water, which extends to depths > 120m on the shelf (Rikhter et al. 2001)"--Intro.
