the growth patterns of the tail flukes are the 
only sets of measurements in which signi- 
ficant differences have been found to exist 
between the two groups. 
SUMMARY 
Application of the equation Y = bX^ to 
measurements of 9 different body dimensions 
in a sample of 49 adult striped marlin from 
the region of Cape Brett, New Zealand, has 
shown that, in general, growth in these fish 
is isometric with the standard length of the 
body. Slight but not statistically significant 
negative allometry was found in the length 
of the longest ray of the pectoral fin. Signi- 
ficant negative allometry was found in the 
dorsal and ventral flukes of the caudal fin. A 
significant difference in the growth pattern of 
the tail was found to exist between the sample 
reported here and a sample of nine fish of 
similar size from Mayor Island, New Zealand, 
examined by Gregory and Conrad. It is 
suggested that these two samples may repre- 
sent separate populations.
