Comparison of the holdings of various important species during the 

 year 1930 with normal (average 1925 to 1929) holdings of these stocks, 

 shows data of interest. With halibut it is found that during each 

 month in 1930 the holdings were below normal except during the 

 months of January, February, November, and December. Those of 

 sea herring were below normal during the first four months of the 

 year, and then above normal for the remainder of the year. Those 

 of lake trout were below normal during the months of January, 

 February, September, October, November, and December. Those of 

 mackerel were above normal for the first three months of the year, 

 then slumped below normal for the next three months, and returned 

 to considerably above normal for the remainder of the year with 

 the exception of November and December, when they were slightly 

 below normal. Those of salmon were somewhat below normal during 

 the first six months of the year, and then during the latter six months 

 holdings increased at an unusual rate. Those of squid were con- 

 siderably below normal from January to April, inclusive. During 

 this period the shortage of squid for bait became rather acute. How- 

 ever, from May to December the holdings increased and were con- 

 siderably above normal. The holdings of whiting were considerably 

 above normal every month during the year except during May, 

 when they were practically normal.
