*An "observation" is a set of effort and catch data for a 5° square for a single 

 month. A total of 24 observations in 1961 and 1962 have been eliminated and 

 raising factors adjusted appropriately as stated in the text. 



**Includes southern bluefin - previous to 1966 the published statistics do not 

 separate the two species. 



Less than 500 fish. 



for month-squares, the data were grouped January- March 176 squares 



. . r i • ' April-June 193 



into quarters for analysis. July-September 203 



The number of squares fished at least once October-December 200 



in each quarter in the 13 years is: Squares not fished are shown in Table 2.
