One evidence of early tarpon angling comes from Henry Thomas in his book “The Rod in India.” In 1873 he talks about catching oxeye tarpon with white flies in the following account:
Megalops Cyprinoides ... also takes a bait well at times. I have come across them coming up an estuary in a shoal, and it was like hauling in Mackerel; they run about the same size. There was a fish on as fast as ever you could get your line in the water. But the fun was very short-lived. It was in mid stream and they were all past the boat in very little time. I am told they, as well as Elops Saurus, have been caught in Madras Fort ditch with a white fly. My fishing for them was with a small dead-bait.
Don't know if they are still available in Chennai (Madras).
So, the oxeye tarpon is surely found in India.
