Theory 29/Seasons to Years/Fisheries
Collapse Is Generation Against Harvest
The claim
Fishery collapse occurs when the ratio of generation time to harvest rate falls below a threshold, so a slow-growing stock collapses at a lower harvest than a fast-growing one.
01Mechanism
Recruitment must replace removals before the next generation matures; the ratio determines whether replacement is possible.
02Prediction
Collapse should track the ratio.
03Refutation
Collapse tracking biomass would remove generation time.
