IT SURE IS!!!
Check out this Black Marlin we caught and released out of Cairns a couple of years ago. Estimated at 900lbs.
We caught a bigger one which ended up dying on us through out the 2 1/2 hour battle last October.
We weighed it on 'Ultimate Lady' which you might know of from New Zealand. She pulled the scales at 1140lb. But more about that one later.
