19^1. Status of the lalce trout fishery in Lake Superioro 



Trans. Am. Fish. Soc, Vol. 80, (19^0), pp. 278-312. 



Review similar to that in other 19I?1 article by same 

 authors for Lake Michigan, No evidence existed of injury to 

 lalce trout in Lake Superior by sea lamprey through 1914.9. 

 Stocks were nevertheless in precarious condition as result 

 of long-term trends which had led to excessively high fish- 

 ing pressure and abnormally low availability in State of 

 Michigan waters (and probably in other regions of lake) by 

 that year.
