Overfishing Shrimp: Which Species Declines First?

To determine which organism's population would decline first if shrimp were over-harvested, I need to see the specific food chain.

For example, if the chain is:

Phytoplankton → Zooplankton → Shrimp → Red Drum

Then overfishing shrimp would directly impact the Red Drum population, because they rely on shrimp as a food source.

Please provide the food chain, and I can help you identify which population would be affected first.
