Figure 3— Number of dolphin sets (upper portion) and percent of zero-kill dolphin sets (lower 

 portion) for each of 3 areas (NIS = North Inside, NOS = North Outside, S = South) by period 

 within year (open symbol = Jan.-Mar., closed symbol = Apr.-Dec). Data are from NMFS-observed 

 trips, 1978 through 1982. Vertical line separates data before and after March 1981. 



Table 4.— Numbers of dolphin sets (n) made from 1979 through 1982, during lATTC-observed trips. Sets are classified by date of set 

 relative to March 1981 (before or after) and to period (1 = Jan.-Mar., 2 = Apr.-Dec), by area of set (North Inside, North Outside, South), 

 and by numbers of dolphins killed (0, X)). Percents of column totals (%), expected frequencies (e), and the statistic x^ with degrees 

 of freedom (df) are also tabulated. Values of x^ > 3.84 (1 df) or 12.59 (6 df) are significant, as Indicated by an asterisk.
