Remarks 



Very strong mode about 14 cm., hint of 



a submode at 22 cm. 

 Fairly strong submode about 14 cm., 



mode at 22 cm. 



Strong mode at 17 cm. 



Strong mode about 23 cm. 



Strong mode about 22-23 cm. 



Hint of a submode at 16 cm., mode at 

 23 cm. Higher values tail off rather 

 gradually, owing perhaps to larger 

 males growing more slowly than females 

 of similar age 



Submode at 14 cm., mode at 22 cm. 



Ill-defined mode — the values at 19-22 

 and at 24 cm. all high. This is readily 

 understandable if the hypothesis as to 

 slower growth of mature males is ac- 

 cepted 



Two well-defined modes at 14-15 and 

 at 22-23 ^^■ 



Strong mode at 27 cm. Here we seem 

 to have a later year class (? Hl-group) 

 dominant than at any of the other 

 stations. Note that this is the only rich 

 autumnal haul in deeper water 



Very strong mode at 15 cm.
