MYSTIC, Conn. (AP) -Aquarium officials struggled yesterday to keep an ailing, 600-pound pilot whale alive after it was flown to Mystic r from Atlantic City. r. ' A spokeswoman for Mystic Marinelife Aquarium said staff members spent the day in the large tank, "walking" .the whale, keeping its blow - hole above water so it would-,- n't drown. r The whale is stricken with i pneumonia and possible injury to its central nervous system. It received an anti- . bfotic inoculation yesterday, and officials were awaiting C the results of a series of laboratory tests. r" Laura Kezer, a spokes- woman, said the whale had " eaten several pounds of fish since its arrival, which she said was a good sign. The olive-black male, 1 which beached itself in Wild-wood May 26, was airlifted - from the Marine Mammal Stranding Center in Atlantic City to Trumbull Airport in Groton, and then taken by National Guard truck to the aquarium where it arrived at about 3 a.m. " "It seems to have some very strange swimming . habits," Ms. Kezer said. "But we haven't had enough time to determine whether : this is a problem with its ability to swim or if it's a behavioral thing. "Someone who saw it . bumping into the sides of the tank said the whale had the turning radius of a Mack truck,'' she said with a laugh. The whale, which is be-lieved to be 3 or 4 years old, is in the same tank with another of the aquarium's "rescue" projects, the only known Commerson's dolphin in captivity. The rare, piebald (spotted) dolphin has been here for nearly six months. It was seized after being shipped illegally into the United States en route from Argentina to Japan. "We're very pressed for room here," Ms. Kezer said. "The two animals seemed to get along." ' The New Jersey center had nursed the whale through several brushes with death in the last 16 days. The whale was moved to the Con- necticut aquarium to combat its infections. A6 Asbury Park Whale's 'Doctors' Persist
