In 1977, Peter Larkin wrote its epitaph, challenging the goal of maximum sustained yield on several grounds: It put populations at too much risk; it did not account for spatial variability in productivity; it did not account for species other than the focus of the fishery; it considered only the benefits, not the costs, of fishing; and it was ...
Peter Anthony Larkin, OC OBC FRSC (1924–1996) was a fisheries scientist who spent most of his career at the University of British Columbia. [1] [2] [3] After his PhD at the Exeter College, Oxford, he moved to Canada as the Chief Fisheries Biologist of British Columbia, in a joint appointment between the provincial government and the University of British Columbia (UBC).
This point is called the maximum sustainable yield, and in practice, usually occurs when the fishery has been fished down to about 30% of the biomass it had before harvesting started. [ 24 ] It is possible to fish the stock down further to, say, 15% of the pre-harvest biomass, and then adjust the harvest rate so the biomass remains at that level.
The concept of maximum sustainable yield (MSY) has been used in fisheries science and fisheries management for more than a century. Originally developed and popularized by Fedor Baranov early in the 1900s as the "theory of fishing," it is often credited with laying the foundation for the modern understanding of the population dynamics of fisheries.

Long term constant yield is the idea that undisturbed nature establishes a steady state that changes little over time. Properly done, fishing at up to maximum sustainable yield allows nature to adjust to a new steady state, without compromising future harvests. However, this view is naive, because constancy is not an attribute of marine ...

Reduce optimal yield from lack of information of a stock; Establish a reserve as the creation of a reserve may include uncertainties in estimating domestic harvest, stock conditions, or environmental factors; Adjust management techniques as a council could guard against producing drastic changes in fishing patterns, allocations, or practices
