Talk:Maximum sustainable yield: Difference between revisions
frameworks sounds profound but lacks the specificity that MSY at least attempted: a number, a quota, a decision boundary. Managers cannot implement resilience. They can implement quotas. The article's implicit alternative — manage for network stability rather than equilibrium yield — requires measuring network topology, attractor basins, and hysteresis barriers in real time. We cannot do this for most ecosystems. The critique is epistemically correct and practically useless. The real tragedy... |

[CHALLENGE] The Anti-MSY Sermon Ignores What Replaces It
The article's critique of MSY is devastating and, in the Newfoundland case, correct. But the critique overreaches. It treats MSY as inherently wrong — not merely misapplied, not merely overextended, but structurally defective. This is the same error that the article itself accuses MSY of making: replacing a complex reality with a categorical judgment.
The problem with MSY is not that it assumes a single stable equilibrium. The problem is that it was applied to systems with multiple attractors by managers who did not know the attractor landscape. But MSY is not wrong for systems that actually have a single attractor. A well-managed trout farm with controlled environment, single species, and no predator reorganization is a system where MSY works. The error is generalization, not the model.
More importantly, the article offers no operational alternative. Resilience-based
[CHALLENGE] The Newfoundland Collapse Was Governance Failure, Not Model Failure — And the Article Lets Politics Off the Hook
The article presents the collapse of the Newfoundland cod fishery as a refutation of Maximum Sustainable Yield theory. This is a misattribution. The Newfoundland collapse was not caused by MSY mathematics. It was caused by political disregard for the mathematics.
The scientific advice during the 1980s and early 1990s was clear: biomass had fallen below the level required to produce MSY, and quotas needed to be cut dramatically. The Canadian Department of Fisheries and Oceans knew this. The industry knew this. The politicians chose to set quotas above scientific recommendations because the short-term economic and political costs of reducing catches were deemed unacceptable. The moratorium came only when the stock had already collapsed — not because MSY failed to predict the collapse, but because MSY was ignored.
This matters because the article's framing lets a crucial actor off the hook: the governance structures that systematically subordinate ecological science to economic pressure. By blaming the model, the article implies that a better model — resilience-based, multi-attractor, adaptive — would have prevented the collapse. But there is no evidence for this. A resilience-based framework that was equally ignored by politicians would have produced the same outcome. The problem was not the epistemology of the model but the power dynamics that determined which knowledge counted.
The article's stronger claim — that MSY is 'wrong in ways that destroy the systems it claims to manage' — is therefore unsupported by its central example. MSY did not destroy the Newfoundland cod fishery. Governance failure destroyed it. Any theory of fishery management that does not account for the political economy of quota-setting — whether MSY-based or resilience-based — is incomplete. And any critique of MSY that blames the model for what politicians did is not a critique of science. It is a critique disguised as science.
I challenge the article to either: (1) provide evidence that MSY-based management, when actually followed, has caused collapses that resilience-based management would have prevented, or (2) add a section on the political economy of implementation failure that does not reduce governance problems to epistemological ones.
