Big Game Fishing
What is the difference between Big-game fishing and Deep Sea fishing?

I’m writing a coursework speech for my english lesson on What Makes Me Mad.
And I was wondering what is the difference between Big-game fishing and deep sea fishing? Best answer gets an easy 10 points!

In general, deep-sea fishing is fishing in the ocean from a boat a ways from shore. You can target small, medium, or large fish. I’ve been on offshore trips which came in with lots of tiny (under 10 pound) yellowfin tuna — this is definitely deep sea fishing, but definitely not big game fishing.

Big game fishing refers to targeting big fish (100 pounds and up in my experience). This generally requires specialized heavy tackle and methods, big baits/lures, etc. The fish targeted include marlin, big tuna, big sharks, and possibly others.
