International Game Fish Association IGFA Whale sharks are by far the largest fish in the ocean, weighing up to 90,000 lb and reaching 59 feet in length. They are generally considered harmless. When fishing depths of over 30 feet, you should bring a fish up slowly to the boat. Pause while reeling the fish in and allow the air bubbles from the fishes decompression to rise to the surface.
Fish can get the bends almost like people.
If you reel a fish in too quickly, it will die.
