Seals that survived their first year were on average 2% and 4% heavier at birth and at weaning than the “non-survivors”. First year survival rates were also calculated for weaners in the top quartile of weaning masses, these weaners had higher survival rates than those in the light quartile (71.
Elephant seals were immobilized intravenously with a mixture of tiletamine and zolazepam at a rate of 0.5 mg/kg. This provided a satisfactory degree of anaesthesia with no side effects. Induction, duration and recovery times were short which proved advantageous to researchers and animals.
