 pooled sexes of C. lida, are pre-

In C. lida, the tests made to check the relationship 

 between length and weight during various stages of 

 maturity (immature, maturing, and mature) in males 

 and females showed significant differences between the 

 three maturity stages in females alone and in pooled 

 sexes, whereas males showed no significant differ- 



for juveniles, are 



C. lida 



Male & female 

 Juveniles 



The linear relationships in log- 

 arithmic values of length and 

 weight for immature, maturing, 

 and mature female, as well as 

 pooled sexes of C. lida, are 

 shown in Figure lOB. 



Although female maturity ex- 

 hibited a significant effect on the 

 length-weight relationship, all 

 data for male, female, and juve- 

 nile C. lida were treated separ- 

 ately, irrespective of month and 

 maturity stage. Analysis of co- 

 variance was used to find vari- 

 ations in the growth patterns of 

 males, females, and juveniles. 

 Significant differences were ob- 

 served in regression coefficients 

 of males, females, and juveniles. 

 While comparing males and 

 juveniles, a significant difference 

 was noted; however, no signifi- 

 cant differences were observed 

 in comparing males and females, 

 and females and juveniles. Hence 

 two logarithmic equations, one 

 common equation for adults 

 (male and female) and another 

 presented for C. lida as follows, 



logW = - 5.8643 -H 3.2761 logL 

 logW = - 6.5983 -H 3.6579 logL, 



and the parabolic equations are
