The Productivity of Fish Food in Oneida Lake yy 



thought that mussels might be found in the deep water of 

 the creek but none were collected, and probably none were 

 present. A few dredgings with the rectangular dredge would 

 be interesting. 



2. Johnson Bay, North Shore of Oneida Lake. This em- 

 bayment is directly across the lake from Lower South Bay. 

 It is a small bay about a third of a mile long and over an 

 eighth of a mile wide. The water is from four to six feet 

 deep and the bottom is mostly of firm sand, with a few mud 

 areas in sheltered places. Vegetation consists of Lake Bul- 

 rush (Scirpus occidentalis) , Pickerel Weed {Pontederia cor- 

 data) and White Water Lily (Castalia odorata). The shore 

 is lined with Swamp Loosestrife (Decodon verticillatns) . Col- 

 lections were made in three habitats as noted in Table No. 15. 

 Many of the specimens were immature. The 911 habitat was 

 on the leaves of the White Water Lily, one individual on each 

 leaf. The sponge (Heteromyenia) was found attached to a 

 leaf of Scirpiis occidentalis, just below the surface of the 

 water. It was quite abundant.

3. Graves Bay, South Shore of Oneida Lake, This local- 

 ity is a trifle over a mile east of Lower South Bay. The 

 water is shallow for a great distance from shore, gradually 

 deepening t(j the 6Toot contour which is 900 feet from shore.
