about how long would it take me to get 75 fishing from 65 fishing and cooking salmon and trout?

IF you drop the fish about 1-2 weeks.

cool.... now that i'm off school i can powerfish for like 4-5hrs day....

then its like 4-5 days i think

You can fish ~600 fish per hour, 33-35k xp/hour. (Assuming you catch one salmon for every 3 trout)

 

You can cook ~1k fish per hour, also cutting down the tree and lighting the fire etc.

 

It takes 1 hour and 36 mins to fish and cook 600 fish, 96 minutes.

 

600/96 = 6,25 fish per minute, 375 fish per hour.

 

So, thats 77,5 cooking xp and 55 fishing xp per fish on average.

 

 

 

29k cooking and 20,5k fishing xp per hour.

 

It would take 37 hours to get 75 fishing this way, and you will get 77 cooking too.

 

 

 

EDIT: A week, playing 5 hours a day.

A week. Good Luck.
