Comparison of bathymetrio distribution of fish in four 

 lakes J revealing a -fcride variation from one water to another 

 azA) except for the Cisco ^ a lack of clear-cut dependence of 

 that variation on such factors as temperature, and concentra-

 waters of Green Bay^ Fisho Bull,, Fish and Wildlife 

 SerVo, Volo (in press). 



Comparison of production levels and trends in 188^, 

 I89I-I908, and 1929-19 li9 and description of relations of 

 fluctuations in production, abundance, and fishing intensity 

 in last- period. Questions soxmdness of interpreting decline 

 in mean annual take of all species from 7 million po\inds in 

 1691-1908 to 3 1/2 million pounds in 1929-19U9 as result of 

 overfishing^ the relatively cheap lake herring alone more 

 than accounted for the decrease whereas the average annual 

 take of more prized varieties increased (for example, annual 

 yield of the valuable whitefish in 1929-19 U9 was U 1/2 times 

 that in 1891-1908) Concludes with discussion of problem of 

 regulation.
