This will be my first blog post in this community. Please excuse my english, I'll try to be as clear as I can for the sake of your reading experience. :)
So, I've always been very good at keeping stats for almost everything I do on my PC, including my Fish Hunt experience so far. The data that I've compiled is not a lot but I want to share it with hope that it would be helpful for novice fishermen like me and even for someone a little bit more experienced. I'll also appreciate some advice from more experienced players on the future (leveling) of Fish Hunt and how the profits scale. :)
My stats are the following:
15 full runs on only 1x multiplier with a Deluxe Rod on credit and ~6,000 starting Fish Hunt XP (~3,000 place in the Leaderboard)
Total fish hunted: 662
Total small worms used: 462
Total experience: 6311 (the xp after the 5th run is like 3x or 12 per fish)
Gross profits: 131,15 L$
The number of fish that can be caught in one fish buoy are min 41/max 45.
From the 662 fish I've managed to fish up, I caught small worms exactly 67 times which put the chance for small worms almost exactly at 10%.
From the 662 fish I caught 13 biowaste putting the chance for biowaste at ~2%
Let's put some average numbers in here and a conclusion on my hunt:
Average XP per caught fish: ~9,53xp/fish
Average $L per fish: ~0,20 L$
Average $L per small worm: ~0,284 L$
With the average current price of small worms which is around 0,24 L$ my profits per caught fish are:
131,15 L$ - (462 x 0,24 L$) = 20,27 L$
20,27 L$ / 662 = ~0,03 L$ per fish caught
If it took you an average time of 1 min to catch a fish, you are going to net around 1,8 L$ per hour fishing with my current rank and experience. If we include the biowaste (given that you have pro or deluxe rod) you will make approximately 1 L$ more per hour if you sell it at the ask price.
Since I don't have any idea what would be my profit when I climb up the ranks, for now my conclusion is that it's not very profitable but still is above break even which is good. That means that you can level up your fish rank without spending any money and even making some in the process. Of course my data is not sufficient to draw any strong conclusions, just some idea of what will be your approximate profits when you first start up your Fish Hunt journey.
I hope you will find this data if not helpful at least a little bit interesting. :)
