352 FISHERY BULLETIN OF THE FISH AND WILDLIFE SERVICE were in the same interval (81-90 feet). The strongest indication of two concentration zones of illegal fish is found in the scanty September data. Young whitefish were much scarcer in the shallower water of the .Saginaw Bay area than at corresponding depths on the Alpena-Ossineke grounds. HARBOR BEACH GROUNDS The observations of 55 lifts of deep trap nets off Harbor Beach (no pound nets were observed here) were all made in the latter part of the 1932 season (table 26), when on the basis of the preceding data the whitefish would be expected to be concentrated in the deeper water. Actually here is where the deep trap nets were found in operation. Fifty of the lifts were made from depths greater than 90 feet. Consequently, no detailed description of the vertical distribution of whitefish at all depths in this area is possible. The maximum concentration of both legal and illegal whitefish occurred in the 101-110 foot interval in all three months. In the season's average the number of legal fish per lift was greater at 91-100 feet than in waters deeper than 110 feet, but the reverse relationship was found in the data for illegal whitefish. The single shallow-water lift (41-60 feet) contained no whitefish. The legal whitefish were more abundant than the illegal fish at all depths.

The data of table 27, however, indicate rather clearly that legal whitefish in this region were in deeper water in September (61-^80 feet) than in May (60 feet and less). Illegal whitefish were relatively numerous in May at depths less than 61 feet, and were present in large numbers also in the two lifts from the 81-90 foot interval. Few illegal whitefish were taken at any depth in September. >12Û 135 8 (5) 163.0 (3) 46.0 (2) Í2ÍÕ (10) >120 79.0 (5) 75.3 (3) 55.5 (2) 73.2 (10)
