Why are whale sharks going extinct?

Despite this, the IUCN (International Union for Conservation of Nature) has declared the species endangered due to the impacts of fisheries, by-catch losses, trash pollution, and vessel strikes. These factors, combined with the whale shark’s very long lifespan and very late maturation, spell recipe for disaster.

What is the largest fish ever caught on Wicked Tuna?

In 2018, the Wicked Tuna cast sat down to discuss their biggest tuna catches to date. Brad Krakowski’s biggest catch weighed in at 920 pounds, while Dave Marciano’s fish clocked in at 1,200 pounds and 118 inches. TJ Ott surpassed his crew mates with a 1,250 pound, 125 inch tuna caught off the coast of Cape Cod.
