of other trout. Of the entire 56 streams where eastern brook trout 

 made up more than 50 per cent of the catch, 16 of them had one or 

 more species of fish released where these species constituted less 

 than five per cent of the catch. 



This table demonstrates that the species of fish planted from 

 hatcheries do not always correspond to the species appearing most 

 often in the catch and that many streams, particularly those in which 

 eastern brook trout are dominant, are receiving little benefit from 

 hatchery releases. Creel census will, thus, enable the Fish and 

 Game Department — 



(1) to discontinue planting species of fish that do not appear ma- 

 terially or do not appear at all in the catch, 



(2) to plant the species of fish that will give the anglers the 

 greatest return, 



(3) to prohibit the introduction of new species of fish that prior 

 knowledge shows are incompatible with resident fish, 



(4) to maintain a constant check on the quality of fishing in 

 individual waters, and 



(5) to check the effectiveness of old and new management meas- 

 ures.
