The Prod^ictivity of Fish Food in Oneida Lake 49 



ton natans, richardsonii, perfoliatus, interruptus, and robbinsii 

 are also present. Such habitats occur in the west end of Short 

 Point Bay, on the south shore of Lower South Bay, and at the 

 extreme southeast corner of the bay, east of the steamboat 

 landing (see the vegetation maps, figures 18 and 19). 



2. Low Shores, partly Protected, with Clay or Sand Bot- 

 tom. Such habitats occur on the south shore of Long Point, 

 south shore of Short Point, and in the southeast and south 

 part of Lower South Bay. There is no sharp line between 

 types I and 2, the latter habitat, however, not having the But- 

 tonbush. Loosestrife, or Black Willow on the shore. There 

 may be Cat-tails, Arrow-heads, Pickerel-weed, Bur-reed, 

 American or Lake Bulrush, and a few Water Willow border- 

 ing the shore and extending to water three to four feet deep. 

 Such submergent plants as Elodea, Vallisneria, MyriophyUum, 

 and the Pond-weeds Potamogeton lucens, perfoliatus, richard- 

 sonii, robbinsii, and interruptus may also be present. 



3. Pond-like Areas. In the shallow coves and bays on the 

 south shore of Short Point Bay, the south shore of Short 

 Point, in Short Point Bay, and along the south shore of Lower 

 South Bay, where the bottom is more or less of mud and the 

 area is protected to some extent from the rough water, habitats 

 are formed which resemble those of ponds, and are character- 

 ized by the presence of Castalia, Nymphoea, Potamogeton 

 natans, perfoliatus, richardsonii, robbinsii, and interruptus, 

 Elodea, Vallisneria, Utricularia, Lemna, Najas, and Chara. 

 Such places are favorite haunts for fish, where food is abun- 

 dant. (See the maps, figures 18 and 19.) 



4. Sandy or Rocky, Exposed Shores. In these habitats, 

 which are either on exposed points or on shores subject to the 

 full force of the wind and waves, the vegetation is confined to 

 a few species, which, however, grow in great profusion. At 

 the end of rocky points, like that at the end of Long Point and 

 on Short Point, the W^ater Willow is very abundant, growing 

 in heavy masses, usually in groups or "islands" of greater or 

 less size. With the Water Willow is usually found the Lake
