Prey Species

 

Flyingfish On DeckMid-trophic species are the primary prey of many marine mammal species. We use data on the abundance and distribution of mid-trophic species to understand trends in mammal abundance and to predict marine mammal distributions. We have collected data on the abundance and distribution of mid-trophic species in the eastern Pacific Ocean using active acoustics and net tows. In the eastern tropical Pacific, we have extensively studied the distribution and abundance of flyingfish.
