Ultrasound for seals

fur seals on the Pribilof Islands

U of S Veterinary Biosciences Prof. Dr. Gregg Adams collaborated recently with Dr. Ward Testa of the National Marine Mammal Laboratory in Seattle in an expedition to the Pribilof Islands in the Bering Sea off Alaska.

Fur seals once numbered in the millions, but now have dwindled to a few hundred thousand. Adams, a leading specialist in comparative reproductive biology, wanted to determine if pregnancy diagnosis using ultrasonography in wild seals in their natural environment was feasible.

The expedition was a success. Adams and his team were able to use ultrasonography to examine the reproductive organs in pregnant and non-pregnant females. Ninety per cent of the females examined were pregnant.
