Dok: I have "Life of Animals" in the library in 6 volumes (7 books) of the first Soviet edition (the 1970s). There in the 4th volume is an article about the fish mintai. It was mentioned that due to its low nutritional value, it is massively mined mainly for livestock feed.
After 10-15 years I got the 3rd edition of The Life of Animals. The article about the mint has grown significantly, and especially relied on the number of delicious and healthy dishes that can be cooked from this fish. Make the conclusions yourself.
