"I caught a barred knifejaw! I'll have to use it to cut veggies!" —New Leaf

The barred knifejaw (イシダイ, ishidai?) is a rare fish found in the ocean and sells for 5,000 Bells at Tom Nook's store. It appears all day in spring and summer and is black with seven white stripes. Its shadow size is small/medium, around the same size as the squid, octopus, puffer fish and dab. The fish, along with all other ocean fish, appears in the back tank when donated to the Museum, and is considered to be quite a hard fish to catch, as Blathers will tell the player when they donate it.

Donation to the museum

In Animal Crossing

When the player donates the fish in Animal Crossing, Blathers the curator will say:

"Hoo! Indeed, WOO hoo! A barred knifejaw, I believe. Hoo!  Hoo, I say!  Just look at this magnificent creature!  Truly, a king among edible aquatic beasts of the world! Tuna, scallops, oysters, lobsters, salmon, halibut, crabs, barnacles... Well, maybe not barnacles... One would have to be in dire straits indeed to consume a few of those jagged beasties!"

"Now then, what say we set this chap up in his new home, eh wot?"

In Wild World

When the player donates it in Wild World, Blathers will say:

"<player>, the very fact that you caught this tells me that you are quite a fisher! Oh, a recipe for barred knifejaw? I'd recommend putting it in a broth. Grilling makes the flesh rather tough, eh wot?"

In City Folk

When the player donates it in City Folk, Blathers will say:

"Hootie hoo, look at you! You've hauled in a star catch this time! Indeed, simply marvelous work!' The barred knifejaw is a clever fish that, it's said, requires some rather fancy fishing to catch. Their monotone color scheme certainly paints them as smart, sensible fish in my eyes, eh wot?"

In New Leaf

In New Leaf an information board in the aquarium will list information about this fish.

"Barred knifejaws stand out thanks to the seven stripes adorning their white bodies. Their natural curiosity and strong pull make them a popular target of anglers, but they're no easy catch. They have strong teeth that allow them to make short work of sea creatures with tough shells. This means that both urchins and mollusks need to be careful, lest they become meals for these fish."
