Because of the absence of large migrations of treska and its sparse dis- 

 tribution commercial trawl fishery of Pacific Ocean treska is impractical. 



In Anadyr Gulf we caught treska from 26 to 100 cm., according to K. I. 

 Panin their average measurements were as follows (855 examples, KRASNO 

 ARMEIETZ, 1933):

and existence of cold currents, indicate large migrations would be difficult. 

 Data concerning the biology and commerce of treska are presented by V. F. 

 Shmidt (Ives. Far East Branch Ak. Nauk SSSR, 1930, no. 1-2-3 (on spawning), 

 "Scientific results of the TI RH investigations in the Bering Sea in 1931-32" 

 (1934, ms.), and "On the penetration and distribution of some codfish families 

 in the north Pacific Ocean", Zool. Jour. Tom. 15, no. 1, 1936, pp. 175-183.)
