You may have already come across the Appraiser NPC in Moosewood, who sits next to the Merchant you often visit to sell fish. When you interact with her, you’ll see an option to “appraise” a fish for 450C$, but that’s pretty much all the game tells you at the start. Before you spend your hard-earned in-game cash, here’s everything you need to know about Appraising in Roblox Fish, how it works, and whether or not it’s worth doing.
Is it worth appraising fish? (SHOWCASE) in FISH! ROBLOX
Appraisal is the act of judging the value or quality of something. So when you bring a fish to the appraiser, she can tell you the price of the fish before she sells it to the dealer. If you choose the option "Can you appraise this fish?", you are unlikely to increase the value of the item you are showing her.
About her work she explains: "I inspect it and re-evaluate the weight. Then I check for signs that it is a Shiny, Mutated or Sparkling fish. And finally I give it back to you!"
For example, I tried to assess a large bass and it lost 0.3 kg in weight, earning me the title 'Unlucky Better'.
