I believe you are awarded this after finishing the quest.

Lure
blue deeps with a lure
I used a lure to catch bonito fish ( at Blue Deeps)
Go to nobearns cave lure ragworm line 50ft
Lake Shiney with a Lure big ones about 70ft+, slowly reel it
At waves of doom, use ragwort or lure and cast at random lengths. If you can, use the red fishing rod. It improves your chance of a collectible such as the mine
Go to lake shiny and use the spinner as your lure. Make sure you do a maximum cast to catch him, and you can change it to an easier way to cast in options on the main menu. Anyway, it's takes a long time to catch him so be patient. Also, if you have the golden lure thingy it will increase the chance of catching it.
Go to eXreme mode at lake shiny use lure and cast 90 feet be patient GOOD LUCK
you get a rectaguler bit of wax and cut out your shape of the fishing lure
In the lumbridge castle can't you fish for bonito in flick fishing
