attained a length of 210 mm in the first year. There was 

 another mode at the 200-214 mm length-group during 

 February. A progressive shift of this mode during 

 subsequent months until November, to the 260-274 mm 

 length-group, indicated a growth of 60 mm in 9 months. 

 Groups could not be traced beyond December. Based 

 on this rate of growth, a fish would reach 290 mm at 

 the end of the second year. Because of poorer represen- 

 tation in older size-groups, later modes were not traced. 



In male C. lida (Fig. 8), the first mode was the 

 102-108 mm size-group in November. This was traced 

 to the 179-185 mm size-group in May, 77 mm of growth 

 in 6 months. Length-groups could not be traced beyond 

 June. At this rate, a fish would be 154 mm at the end 

 of the first year. The mode at the 151-157mm size- 

 group in March was traced to the 179-185 mm size- 

 group in November, 28 mm growth in 8 months. At 

 this rate of growth, a fish at the end of the second
