Terry Hadden, of Rye Bay Fish, said: “I am in my 60’s and have never seen that before in local waters. It is very rare. I don’t think I’ll live to see it again. “The tuna were the smaller skipjack type and weighed around 3kg to 4kg each. “They were caught between Hastings and Rye in a drift net.” Tuna are generally only found in warm waters. They are part of the mackeral family and can grow to lengths in excess of 15 feet in some waters.
