Sam Cassida was fishing for striped bass with clients from Utah on Wednesday. What he caught was a 576-pound bluefin tuna.
The average tuna weighs 550 pounds and the record bluefin weighed 1,496, according to American Oceans.
Cassida, who is captain of Waterdog Charters in Belfast, had his tuna gear with him in the charter boat when some fellow striper guides alerted him that there were bluefin in the area.
