Fenneropenaeus penicillatus (also called Penaeus penicillatus) is an abundant species on Pakistan Coast, locally called as "Jaira". The proximate chemical composition was determined in mid gut gland, ovary and muscle during different stages of ovarian development that was found to be varied among the different tissues examined. Accumulation of different organic constituents was significant in midgut gland and ovary, whereas, muscle did not show any significant variation during maturation process. The lipid content was highest in the midgut gland as compare to ovary and muscle and the quantity was found increasing throughout the ovarian development in midgut gland and ovary while fluctuating in muscle. The increase in the protein content was not as significant in the midgut gland and muscle as that of the ovary during different stages of sexual maturation. The carbohydrate content did not show any significant change in any tissue though found to be highest in midgut gland as compared to ovary and muscle. The present study suggests that there was no mobilization of lipids from midgut gland to ovaries during ovarian maturation and the lipid increase was due to the intake through diet.
