Chirashi bowl from H-Mart. What is this dark fish?


Got a chirashi bowl from Hmart yesterday for lunch on the go. It was overall pretty good but I was not a fan of this dark, almost brown fish in the upper left of the bowl. It kinda spoiled my appetite 🙃 my taste for seafood is weird since I got covid, but this one was just really rough for some reason. Honestly, I had to force it down because I ain’t spitting out food in this economy lol
I’d like to identify it so I can avoid in the future. Thanks!
