Table 7o== Analysis of yellowfin catches by depthj. Smith Cruise 11»

 distributed with respect to depths therefore Islsl 

 ratio is expected from hook groups As B^, and Co 



Conclusion s There is no significant interaction between the data, 



ioOop the values in the cells do not vary significantly 

 from the border totalso Therefore the pooled figure 

 for the cruise can be usedo T?ie data differ signifi- 

 cantly from the Islsl ratio,, and the above hypothesis 

 is rejectedo
