Abstract

Spinner dolphins (Stenella longirostris) feed on individual small (2–10 cm long) prey that undergo diel vertical migrations, presumably making them inaccessible to dolphins during the day. To examine how time, prey behavior, prey distribution, and energy needs constrain dolphin foraging, a calorimeter was used to measure the caloric content of prey items. These data were combined with information on prey distribution in the field and the energetic needs of dolphins to construct basic bioenergetic models predicting the total prey consumption and mean feeding rates of wild dolphins as well as potential prey preferences. The mean caloric density of mesopelagic animals from Hawaii was high (2,837 cal/g wet weight for shrimps, squids, and myctophid fishes). Their total caloric content, however, was low because of their small size. Energy value of prey and energetic needs of spinner dolphins were used to examine the effect of time and energy constraints on dolphin foraging. The results predict that spinner dolphins need to consume an estimated minimum of 1.25 large prey items per minute to meet their maintenance energy needs. If the additional energy costs of foraging are considered, the estimated necessary foraging rate is predicted to increase only slightly when large prey are consumed. If smaller prey are consumed, the total energy demand may be twice the basic maintenance value. Prey density and size are predicted to be important in determining if dolphins can forage successfully, meeting their energetic needs. The prey size predictions compare well with results from previous gut content studies and from stomach contents of a recently stranded spinner dolphin that had enough prey in its stomach to meet its estimated basic maintenance energy needs for a day. Finally, the results suggest that spinner dolphins are time and therefore efficiency limited rather than being limited by the total amount of available prey. This may explain the diel migration exhibited by spinner dolphins that allows them to follow the movements of their prey and presumably maximizes their foraging time.
