Table 80— = Analysis of bigeye tuna catch cj depths 

 Smith Cruise llo 



Hypothesis s 



The population of bigeye tuna is homogeneously dis- 

 tributed with respect to depths therefore a 1§1?1 ratio 

 is expected from hook groups A, Bp and Co 



Conclusion : There is no significant interaction between the data, 



ioeo, the values in the cells do not vary significantly 

 from the border totalo Therefore the pooled figure for 

 the cruise can be usedo The data differ significantly 

 from the Islsl ratio ^ and the above hypothesis is 

 rejectedo
