Ecosystem Health and Biodiversity Fishing and fish abundance Plenty? Tragedy of the commons Bio- diversity Better Policies Fisher men

Part I: Finding the Fastest Fish

Literature Review Over 90 species of fish Movement ranges Depth distribution Migration

Part II: Exploring Patterns of Diversity 1. Acquire independent dataset 2. Index of diversity 3. Quantify diversity

Trawl Data
