What Was the Largest Fish Ever Caught? According to IGFA records, the largest fish ever caught was a great white shark that weighed an unbelievable 2,664 pounds (1,208.389 kg.). Caught off the coast of Ceduna, Australia, in 1959, it took angler Alfred Dean just 50 minutes to win the fight against this one-ton shark.
The largest extant fish overall is the filter-feeding whale shark (Rhincodon typus), which grows on average to 4 12 m (13 39 ft) long, though one female specimen caught in the Arabian Sea off Veraval in Gujarat, India, on 8 May 2001 measured a reported 18.8 m (61 ft 8 in).
