Figure 1 1 



Monthly percentage occurrence of different ova maturity stages in female Cynoglossus arel and C. lida 

 caught commercially off Porto Novo, India, October 1981-September 1982. (Refer to Appendix for monthly 

 sample size). 



maximum number of individuals spawn in September, 

 which is the pre- (northeast) monsoon period in Porto 

 Novo. 



In male C. lida (Fig. 12), immature (Stage-I) speci- 

 mens occurred throughout the year, except July and 

 September, with a peak in January. Specimens at Stage 

 II (maturing) were observed throughout the year, with 

 high percentages at all months, except August and 



September. Stage-Ill (mature) males were available 

 throughout the year, with a peak in September. This 

 indicates that spawning occurs throughout the year, 

 but a maximum number of males also seemed to spawn 

 during September. Maximum occurrence of matiu-e 

 males in September corresponds with maximum occur- 

 rence of oozing females in the same period, and sup- 

 ports this view.
