A number of California sea lions Zalophus californianus were pre-fed certain test diets smelt, squid, herring, mackerel or mixed for 2-4 weeks. Blood samples were then taken, either after a 22 hour fasting period, or, following a test meal, and, in some of these fed animals also at hourly intervals for 4-6 hours. Blood samples were also taken from several newly captured sea lions after varying fasting periods, prior to their first meal in captivity. The concentrations of a number of plasma components protein, glucose, triglycerides, phospholipids and cholesterol and erythrocyte constituents 2,3-diphosphoglycerate and ATP were measured, the latter using whole blood. Plasma glucose levels were found to be higher than in man, except in the sea lions pre-fed herring.
