Fishing:
Total exp to 14: 10080
Total exp to 20: 18000

Gathering requirement starts at 2000 and goes up 40 at 6, 8, then every level after after 9. Caps at 20, so 41320 total exp unless I fucked up the math (I probably did).

Crafting is the same as gathering until level 21, where it becomes +80 per level, then +120 at level 31, and +140 at 41. Caps at 50.
