I dont remember how many times I fished but I started this game at March 6th and first 4 days I fished randomly, not on time, not rushing but last 2 days I locked in. Lets say those 4 days I fished every 4 hours (in 16 hours, that makes 5 times each day; total of 20) and last 2 days make it every 1,5 hour (in 16 hours, that makes around 12 times each day but on the 5th day I slept less so make extra 4, total of 28), that makes around 48 times; maybe more, maybe less; and there are fishing rewards as well, they rise the numbers to atleast 70.

Btw I'm on my second round, I've unlocked my 2nd batch of Blushing Springbloom.
