Beluga whale stranded in Seine to be given vitamins | Whales

French authorities were planning on Saturday to give vitamins to a beluga whale that swam way up the Seine, as they raced to save the malnourished cetacean that is refusing food.

The apparently underweight whale was first spotted Tuesday in the river that flows through Paris to the Channel. On Saturday it had made its way to about 70km (44 miles) north of the French capital.

“It’s quite emaciated and seems to be having trouble eating,” Isabelle Dorliat-Pouzet, a senior police official in the Eure department in Normandy, which is overseeing the rescue operation, told a press conference.

Rescuers had tried feeding it frozen herring and then live trout, but it didn’t seem to accept either, she said.

It is hoped that injecting the animal with vitamins will stimulate its appetite, she said.

Authorities were deciding whether to keep the animal in the waterway so it could regain its appetite or guide it back toward the sea, she said, adding that no decision has yet been taken.

She said that small spots had appeared on its pale skin, but that scientists hadn’t yet determined whether these were a natural occurrence because of the fresh water or signs of health difficulties.

On Friday, Gerard Mauger of the marine conservation society GECC told AFP that despite being a notably sociable mammal, “it is behaving the same as yesterday; it seems very skittish. It rises to the surface only briefly, followed by long dives.”

Judging by sonar recordings, it was also emitting very few of the chirps and quicks the whales are known for, raising further concerns about the animal’s health.
