Heese T., 1990. Cranial osteology of the whitefish, Coregonus lavaretus (L., 1758) from the Pomeranian Bay. Acta Ichthyol. Piscat. 20 (1): 125-141.
The Pomeranian Bay whitefish stock comprises two plastic forms: typical and humpback. Detailed morphological comparisons revealed significant differences between the two form with respect to certain characters. Cranial osteology of 60 individuals showed morphology of the dentary to be different in the two forms, the numerical expression of the differences showing their statistical significance. Values for the remaining characteristics analysed (a total of 21) were similar in the two forms. In addition, some cranial elements were found to be extremely variable. Measurement taken on few skulls only are, however, of a limited systematic value.
