Otoliths of Arctic cod (Boreogadus saida), small Atlantic cod (Gadus morhua), and three other fish species from Newfoundland waters: description and relationship of fish length to otolith length

Distinguishing features of otoliths of two species of gadid fish (Arctic cod, Boreogadus saida, and Atlantic cod, Gadus morhua) are presented and include descriptions of speci-mens smaller than those previously described. Descriptions are also provided for otoliths of northern sand lance, Atlantic h...

Description
Summary:Distinguishing features of otoliths of two species of gadid fish (Arctic cod, Boreogadus saida, and Atlantic cod, Gadus morhua) are presented and include descriptions of speci-mens smaller than those previously described. Descriptions are also provided for otoliths of northern sand lance, Atlantic herring and capelin, three other locally and seasonally abun-dant fish species at Newfoundland. Regressions of body length on otolith length are pre-sented for each of these fish species, to aid in the estimation of the sizes of prey consumed by major fish predators, such as short-finned squid, in coastal Newfoundland waters.
