In addition to qualitative observation of all 47 species, quantitative estimates of %Hb polymerized RBCs were conducted for 7 species found to exhibit Hb polymerization: Boreogadus saida (Lepechin, 1774); Lycodes reticulatus Reinhardt, 1835; Gadus morhua Linnaeus, 1758; Urophycis chuss (Walbaum, 1792);
Merluccius bilinearis (Mitchill, 1814); Pollachius pollachius (Linnaeus, 1758); and Notacanthus chemnitzii Bloch, 1788.
Evaluating a large-mesh belly window to reduce bycatch in silver hake (
Merluccius bilinearis) trawls.
The collection of significantly smaller individuals of 6 fish species, Leucoraja spp., silver hake (
Merluccius bilinearis), longhorn sculpin (Myoxocephalus octodecemspinosus), windowpane (Scophthalmus aquosus), red hake (Urophycis chuss), and ocean pout (Zoarces americanus), indicated that the beam trawl was more efficient than the bottom trawl at collecting juveniles (or younger age classes, <2 years old) for some taxa.
"In the combined take of Silver Hake,
Merluccius bilinearis; Atlantic Mackerel, Scomber scombrus; and Atlantic Herring, Clupea harengus; how many tons would have been harvested each year within the northwest Atlantic ecosystem during 1988-92 if the fishery had been managed sustainably?" Figure 1b shows the observed commercial harvest rate (t/year) compared to the pattern in consumption rates observed among the marine mammal predators feeding on this multispecies complex.
Diet overlap between the atlantic cod, Gadus morhua, silver hake,
Merluccius bilinearis and fifteen other atlantic finfish.
Although historically known for groundfish (i.e., Atlantic cod (Gadus morhua)), haddock (Melanogrammus aeglefinus), silver hake (
Merluccius bilinearis), and cusk (Brosme brosme), these areas have also been commercially fished for sea scallops (Placopecten magellanicus).

In addition to pelagic pair trawl fishing, three vessels fished with bottom trawls during the day for anglerfish, Lophius americanus; squids; silver hake,
Merluccius bilinearis; and scup, Stenotomus chrysops.
