My father cought a hammerhead shark deep sea fishing! The crew killed the shark by drowning it before bringing it onboard. How can this be done?

I don't think a fish can drown. I think they are telling you a story!

Fish have gills which are specialized for breathing in water. When a fish is exposed to air, it's gills can't handle it the way our lungs can. Thus they drown in air and we drown in water.
As for sharks, they need to swim to make water, which usually has dissolved oxygen in it pass through their gills and facilitate gas exchange. If you stop the shark from swimming in still water, the shark won't get enough oxygen and drown!

Most species of shark require forward motion in order for the water to pass over their gills. Sharks caught in nets drown as do they in the scenario you described.

yes here is the answer explained :
A fish out of water, is a fish out of its element. A fish comes fully equipped with a pair of gills, which it uses to breathe under water. The gills extract life-sustaining oxygen from the hydrogen in the water molecules, in order to regulate the amount of oxygen intake. This maintains the necessary balance of the two components of water for the fish to survive.
When a fish is taken out of water, and exposed only to air, not to oxygen and hydrogen containing water, its gills are unable to control the oxygen intake, the delicate balance cannot be maintained, and the gills inhale a lethal overdose of oxygen. The fish essentially experiences death by "drowning.

fish need air just like anything. they just have a way to get it out of the water. H2O. 2hydrogen molecules and 1 oxygen. if a shark stops swimming it dies. that's probably how they killed it. they just called it drowning cause they held it still in the water.

Sharks "breathe" by water passing through the gills..that is why they have to keep moving....(not counting the nurse shark)

Close or damage the gills.
... I also guess you can consider them drowning when they die from not being in water for a long time, technically.

hold a fish still and it will drown.....no moving water through the gills will kill most fish....sharks especially.....they move their entire lives

Fish extract dissolved oxygen gas from water; they do not decompose the H2O water molecules into hydrogen and oxygen.
Aqueous plants extract dissolved carbon dioxide gas from water.

Yes, by dragging water backwards over the gills..
