Crab Fisherman (Mid-Level) vs Mussel Farmer (Mid-Level)
How do Crab Fisherman (Mid-Level) and Mussel Farmer (Mid-Level) compare on AI displacement risk? Crab Fisherman (Mid-Level) scores 64.7/100 (GREEN (Stable)) while Mussel Farmer (Mid-Level) scores 55.0/100 (GREEN (Stable)). Here's the full breakdown.
Crab Fisherman (Mid-Level): This role is deeply protected by extreme physical demands in unstructured maritime environments. AI cannot operate on a pitching deck in 30-foot seas. Safe for 10+ years.
Mussel Farmer (Mid-Level): Mussel farming is dominated by hands-on physical work in open-water and intertidal marine environments — deploying longlines, stripping ropes, harvesting in variable weather and tidal conditions, and maintaining gear that sits in currents and saltwater. IoT sensors and emerging computer vision augment monitoring and grading but cannot replace the worker on the water. Protected for 15-20+ years by Moravec's Paradox.

What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the Crab Fisherman (Mid-Level) and Mussel Farmer (Mid-Level) role pages.
