Elkhorn Slough Elasmobranch Project
How do Elasmobranchs Interact With the Slough?
The interactions between elasmobranchs and the slough environment can be separated into three distinct, but highly related categories:
Feeding Behavior: The slough as a prey rich environment How are elasmobranchs
feeding in the slough?
- Foraging behavior
- Reproductive behavior
- Migratory behavior
Reproductive Behavior: The slough as an important area for breeding How do elasmobranchs utilize the slough for reproductive purposes?
Which species use the slough for reproduction and how?
- What types of prey are being eaten overall?
Who is eating specific prey species?
- How are prey being acquired by each species?
- active pursuit
Migratory Behavior: How elasmobranchs move throughout the slough
- Mate selection site
- Incubation of embryos
- Gravid females may not
necessarily go to the
slough to pup, but to
help incubate their young.
- Is the Elkhorn slough an
important nursery for
What factors affect movement?
- How do elasmobranchs move either within the slough or between the slough and the Monterey Bay?
- Response to predators or prey
- Competition: within one species or between different species
- Age and size
