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.
Twenty-one out of 25 individuals were in the kingcroaker (Menticirrhus spp.) net, three in the hake (Urophycis
brasiliensis) net and one in the flounder (Paralichthys patagonicus) net.
The sum of essential amino acids (except tryptophan, which was not determined) in the muscle tissue protein of marine fish, such as Clupea harengus, Scomber scombrus, and Urophycis
tenuis, varied from 40.73 g to 44.04 g per 100 g of protein .
Other fishes caught but not counted were goosefish, red hake Urophycis
chuss (Walbaum), silver hake Merluccius bilimaris (Mitchill), smallmouth flounder Etropus microstomus (Gill), and Atlantic torpedo ray Tetronarce nobiliana (Bonaparte).
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.
These were mostly demersal (e.g., Pogonias cromis (Linnaeus, 1766), Urophycis
brasiliensis (Kaup, 1858)) and bottom dwelling species (e.g., Porichthysporossissimus (Cuvier, 1828), Prionotus punctatus (Bloch, 1793), Menticirrhus americanus (Linnaeus, 1766)).

These data identified a diverse community on the flanks of the ridge dominated by butterfish (Peprilus triacanthus), bay anchovy (Anchoa mitchilli), weakfish, bluefish (Pomatomus saltatrix), northern puffer (Sphoeroides maculatus), and spotted hake (Urophycis
regia) and few individuals of any species on the top of the ridge, thereby ruling out physiological tolerances as a reason for the observed distribution pattern.
A diverse group of fish predators was chosen with individual species representing freshwater habitats (tigerfish Hydrocynus brevis), marine pelagic environments (bluefish Pomatomus saltatrix), as well as benthic (winter skate Raja ocellata) and demersal (red hake Urophycis
chuss; white hake Urophycis
tenuis; and European hake Merluccius merluccius) marine habitats.
