    dolphin diet

    The dolphins at Kinosaki Marine World were having trouble making high jumps during shows, so trainers investigated and found that the dolphins were too plump to jump:

    Keepers measured their weight and found all had gotten plumper, some up to 22 pounds heavier just during the summer.

    All had the same menu _ about 31 pounds of mackerel mixed with some white fish _ but keepers found the mackerels had gotten fattier, adding too many calories for the dolphins.

    Keepers immediately put them on a weight loss program, feeding them more white fish and less fatty mackerels, while instituting a routine exercise regime, Imazu said.

    Expect updates on the progress of the Diet at Kinosaki Marine World’s WordPress blog (Japanese).
