Reproduction biology of Penaeus merguiensis (banana prawn) emphesis of fecundity in coastal waters of Hormozgan Province, Iran
Penaeus merguiensis is the dominant species in coastal waters of Hormozgan province and approximately constitute 70% of the annual catch composition. Sex rate is analysis in natural population shows that the proportion of males to females is 1:1 and generally this proportion in carapace length is 28.6 and 25.7 mm more than other classes, which its peak is observed in 25.7 mm length class. Also proportion of males to females in May to December and April to May is more than other times which its peak is in December. The analysis of sexual maturation based on carapace length shows that LM50 for females of this species has followed the exponential equation and is equal to 32.8 mm (r^2 = 90%). Minimum and maximum of absolute fecundity of this species with 20.7-31.5 mm C.L. are and 11300 and 14400 eggs respectively. This analysis of relative fecundity of this type showed that the relationship between carapace length and number of eggs was a type of poweral equation (F= 0.1208 C.L 3.8, r^2 = 97%), however this relationship between total length (T.L) and wet weight (W) was F = 0.0002 T.L 7.1 (r^2= 0.68) and F= 0.1942 W 4.02 (r^2=0.58), respectively, which showed the fecundity has 0.1942 W (r more correlation with the carapace length.
