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.
