im doing a report and i was wondering what percentage of fish are getting killed by nets in the ocean?

One percent of the fishermen (the ones with the nets) kill 90 percent of the fish. (The rod and reelers get the other 10 percent.) Of course this varies with species and location, but in general, the netters are responsible for 90% of the kill. Yet the media always talks about "SportAndCommercial Fishermen" as if (a) it's one group, and (b) the sport guys do more of the damage so they're listed first.
As to the percentage of all the fish out there that are getting taken by the nets, that's unknown because they really have no idea how many fish are out there. With nonmigratory species like the rockfish off California, their population estimates can vary by a factor of 2 from one year to the next (and these are fish that take 5-10 years to mature); with open ocean and migratory fish they have even less idea how many there really are. The only consensus is that the populations are significantly down from decades ago, and most likely overharvesting is the main reason.
Then there are some species which are in good shape, due to regulations or other circumstances. (The kelp and sand bass off southern California are in very good shape because they've been protected from commercial fishing for 50 years, while the sportfishermen take a couple million a year. That may sound like a lot, but the bass population is healthy and stable.)
For a report, I'd suggest focusing on one species (Pacific rockfish or Atlantic bluefin tuna or Pacific salmon or whatever) and do a thorough web search for research papers and population studies. Don't write a paper by quoting some stranger off Yahoo Answers.

Marine biologist Carl Safina has written a few books on the subject. He is often quoted in the New York Times when the newspaper does any fish population story.

Do your own homework the question is too broad for anyone to have the space to answer here.

no one can give you that percentage, they can give you rough numbers on by catch, from netting and long lines but that's about it.

Nice answer Pete.
