(A) Prawn (control) showing fully mature vitellogenic stage ovary (O) and hepatopancreas (H). B, C, D showing variation in the gross morphology of ovary and hepatopancreas in TBT treated prawns. (B) Note the reduction in the ovarian development proceeded up to early vitellogenic stage at 10 ng/l, (C) Becomes pre vitellogenic stage ovary at 100 ng/l and (C) No ovarian development at 1000 ng/l. Note the decrease in size of ovary and hepatopancreas in TBT treated prawns compared to control (n = 3). Bar: 50 mm.
