ANCHORAGE, Alaska (AP) _ A marine mammal volunteer said Sunday she's working to save a harbor seal pup taken from the womb of a mother seal killed by hunters on Kodiak Island.

Marian Beck of Halibut Cove, 125 miles southwest of Anchorage, has spent 15 years saving abandoned and injured seals, including several during the 1989 Exxon Valdez oil spill.

''It doesn't have an immune system,'' she said of the latest pup. ''I'm trying to get it through the first week without antibiotics.''

Beck said she won't know for about a week whether the female pup will survive.

The pup's mother was killed Wednesday by Native hunters, who notified authorities when they found the pup.

Beck said she was spending two to three hours a day with the seal, feeding it Pedialyte, a rehydration formula, from a large syringe.

Her goal is to give it enough food to grow and keep it from becoming dehydrated, she said. After about a month she'll turn it lose.

''I just wean them and throw them overboard,'' she said.
