Penguins refuse to eat low-cost fish

As a part of a belt-tightening effort, the Hakone-en aquarium in central Japan’s Kanagawa area has scrapped a few of its conventional and dearer horse mackerel in favour of cheaper mackerel.

However the menu change has not been acquired with common approval, with some penguins resolutely turning their beaks up when the mackerel is proffered.

“They take it into their mouths at first, however then they determine they do not prefer it and drop it.”

He speculates that the uncompromising penguins might have taken difficulty with the scale of their new meals, that are larger than their commonplace fare.

“They sense one thing is off,” he stated.

The issue is much more acute among the many aquarium’s otters, who’ve uniformly rejected the cheaper fish, Shimamoto added.

The ability stated it made the swap after horse mackerel costs rocketed up about 20-30% from final yr, partially due to low catches.

The aquarium remains to be buying some horse mackerel for its feed, however has no plans to revert again completely till costs fall, Shimamoto stated.

“All of it depends upon when issues get again to regular.”
