also a 15 – 20% zooplankton

• Post-spill diet shift– More fish & crustaceans
and less zooplankton

Three deep-sea fish species that live in different areas and exhibit different behaviors:
- Red snapper- King snake eel- Golden tilefish
Golden tilefish had significantly high amounts of PAH, which increased over time
Red snapper and king snake eel displayed episodic PAH exposure
Snyder et al. 2015
Ecosystem Impact: Communities
Fish habitat and fish behavior play a key role in PAH exposure.

Take home messages:
• Landings data are an important tool to help people monitor change in the health of fish and shellfish populations over time.
• Landings alone can not determine the cause of disaster impacts to fishery populations, as many factors such as ocean currents, weather, and management actions, must also be considered.
• It will take a long time for scientists to understand the impact that the oil spill had on the Gulf of Mexico ecosystem, but science is beginning to reveal some pieces of the puzzle.

Take home messages:
• Federal and state agencies closed waters to fishing during the oil spill and developed a plan to collect seafood samples and test them for chemicals found in oil and dispersant before reopening these areas.
• Of the 22,000 seafood samples that these agencies tested during the Deepwater Horizon oil spill, no sample were over the U.S. Food and Drug Administration’s level of concern.
• Scientists are still studying groups of people that may eat more seafood than average to ensure that seafood is safe for these communities.
