near the east shore of South Fishtail Bay, where during the first two 

 weeks of July they were seen spawning in the shallow water. Adult 

 minnows are also fairly frequent in this habitat. As will be seen later, 

 the great majority of adult yellow i)erch thrown upon the beach b>' the 

 waves were stranded while feeding on the trout i)erch in this habitat, 

 practically every individual having a half-swallowed trout perch in its 

 mouth. 



Over the submerged sand bar and on either side of it, where the 

 reeds, Scirpus spp., grow, also between Grapevine Point and Fairy 

 Island, where the various water plants grow to within four to six feet 

 •of the surface, the habitat is slightly different. Here the bass, both 

 M. dolomieu and M. solmoides, the pickerel-pike, Esox lucius, and the 

 rock bass, A7nbIoplites rupestris, are abundant. A trammel net i^slaced 

 with one end barely on the sand-bar, i. e. in about 10 feet of water, and 

 the other end extending into water forty feet deep gave the following 

 results during both sessions:
