A modification in the technique of computing average lengths from the scales of fishes
In virtually all the studies that employ scales, otollths, or bony structures to obtain the growth history of fishes, it has been the custom to compute lengths for each individual fish and from these data obtain the average growth rates for any particular group. This method involves a considerable amount of mathematical manipulation, time, and effort. Theoretically it should be possible to obtain

Movement of parasitic-phase sea lampreys in Lakes Huron and Michigan
A program of tagging was carrie dout in the waters of northern Lake Huron during the fall and winter of 1951-52 in order to supplement the small amount of information available on movement of sea lampreys during their parasitic phase. A total of 219 parasitic-phase sea lampreys were tagged and released at three localities. Of this number 38 or 17.2 percent were recovered. One tag was recovered nea

War on lampreys
Vampire-like sea lampreys look somewhat like short sections of garden hose, swim like eels, and live solely on the blood of fishes. Their voracious appetites have been especially harmful to fish in the Great Lakes, and it is there that methods of underwater electrocution are being applied in their control.

Lake fisheries need lamprey control and research
Since 1921, when the first sea lamprey was recorded from Lake Erie, concern about this parasite in the Great Lakes above Niagara Falls, where previously it had never occurred, grew successively. At first, the concern was shared only in scientific circles, but as the parasite continued its persistent and rapid spread throughout the upper Great Lakes this concern was voiced by state conservation de

Technique for the application of a streamer-type fish tag
Principal features of the technique are: attachment of the plastic tag by means of a nylon-thread loop prepared in advance of field work; use of a curved surgical needle with cutting edge and a split eye for application of the tag. The procedures for splitting the needle's eye and for applying the tag are described and illustrated by a series of photographs.
