Basic principles of supply and demand, particularly how fluctuations in harvest volume (e.g., record catches) affect market pricing.
Fundamental concepts of marine biology and ecology, including the life cycle of crustaceans and their dependence on specific ocean temperatures.
An introductory understanding of climate change indicators, specifically ocean warming, acidification, and their general effects on marine habitats.
The basics of fishery management, including concepts of sustainable yield, seasonal regulations, and the role of state and federal wildlife agencies.
Advanced bioeconomic modeling used to predict fishery yields under various climate change and ocean acidification scenarios.
The analysis of seafood supply chain logistics and global market dynamics, exploring how local catches transition from 'sea to table' globally.
Economic diversification and adaptation strategies for coastal communities vulnerable to climate-induced disruptions in traditional fisheries.
The study of marine biotoxins (such as domoic acid) and the public health protocols required to monitor seafood safety amid rising ocean temperatures.

Dungeness crab is Oregon's most valuable single-species fishery, generating over $90 million annually and supporting coastal communities through a complex ecosystem dependent on wind-driven upwelling that brings nutrients to the surface, creating conditions for phytoplankton blooms that sustain the entire marine food web; however, climate change threatens this delicate balance by altering upwelling patterns and increasing harmful algal blooms that produce domoic acid, making crabs unsafe for human consumption.
