Fat dolphins go on a diet at Kinosaki Marine World
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).
