Energy Sources in the Diving Mammal: I. Plasma Levels of Fuel Sources in the California Sea Lion 'Zalophus californianus'. II. Carbohydrate Metabolism in Erythrocytes of the California Sea Lion.
Abstract
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.
