Food habits and consumption rates of cod from the southwestern Gulf of St. Lawrence (1979) / by Kenneth G. Waiwood, Jacek Majkowski, and Gregory Keith.: Fs70-8/80-37E-PDF

"Stomach content analysis was conducted on over 1200 cod from the southern Gulf of St. Lawrence (1979). Invertebrates, mainly euphausiids and brachyuran crabs accounted, by weight, for 60-90% of the total food intake. Fish prey increased in importance with increasing predator size. By comparison to earlier studies, the percent occurrence of fish pretty was lower, particularly that of herring. On the other hand, capelin occurrence was higher than previously observed. Using the above data, population estimates, and the Ursin growth theory estimates of the biomass of capelin and flatfish consumed by cod in the study area in 1978 were made"--Abstract.
