Contributions to Canadian Biology and Fisheries
Depth of caudal peduncle in head L. horengus. L. sisco huroniu,s. L. ontar'iens'is. 2.66 L. ortedi 2.0-2.5 L. eriensis . ' Accordingly for each fish examined the necessary measurementg were made for the,calculation of the above proportions. In addition the girth. and the weight were deterr+ined and scales removed for age estimation. From June 14 to August 24, lg2}, the ciscoes taken in twenty pound nets at the Crewe Bros. Fishery neaf Merlin were examined daily. In August and November the fish
... aken at Port Dover, Nanticoke, McKillop's Fishery (near Port Maitland) and Dunnville were examined. The following species have been identified: (l) Leu.cichthys s'isco huron'ius (J.& E.), Lake Huron cisco. This species was readily distinguished by the long spindle-shaped body. The average proportions for 60 individuals were as follows: head in length 4.6, depth in length 4.3, depth of caudal peduncle in head 2.95. These figures are practically identical with those given by Jordan and Evermann for Lake Huron. This species is taken rather abundantly in the pound nets at Merlin but very few specimens were seen east of Long Point.
