three species were plotted against month of capture 

 to examine the possibility of seasonal patterns in the 

 relations. None was found. 



Multivariate analysis was used in an attempt to 

 develop a method of sexing white marlin given 



weight, caudal spread, and the measures of length. 

 Approximately 75% of the specimens could be prop- 

 erly sexed. Although this procedure produced better 

 results than pure guesswork, the results are not satis- 

 factory for scientific purposes.
