How long will it take you to get 99 Fishing on Runescape?

There's really no way to speed up the process of levelling - it'll take hard work and determination to reach 99 Fishing. There are several different strategies that may or may not be beneficial to you, like:

-Catching on Salmon and Trout after level 30; until level 99.

-Fishing Tuna and SWordfish after level 45; until level 99.

-Using Daemonheim Dungeon's fishing areas; they are rich in EXP points.
