  Maximum sustainable yield - Wikipedia, the free encyclopedia
In population ecology, maximum sustainable yield or MSY is the largest long-term average yield/catch that can be taken from a species' stock without depressing the species' ability to reproduce.
The maximum sustainable yield is usually higher than the optimum sustainable yield.
The idea of maximum sustained yield is to decrease population density to the point of highest growth rate possible.

 Management
According to the legislation, the goal of marine mammal management was to "obtain an optimum sustainable population keeping in mind the carrying capacity of the habitat." Violations of this act are punishable by fines of up to $20,000 or imprisonment up to one year.
Optimum sustainable yield combines the maximum sustainable yield with biological, ecological, and socioeconomic data (Reynolds et al., 2000).
Optimum sustainable yield should be implemented more frequently with more data and knowledge of other resources.

 IWMC - Overfishing in the Global Village / 19 March 1998
While free-access has stimulated the traditional model that a fish that is not captured by one fisherman can be captured by another, the tragic reality began to be exposed in the 40s decade, when the importance and behavior of the so-called highly migratory species was known, with little uncertainty.
The situation promoted the creation of a series of intergovernmental scientific fishing organizations, devoted to recommend quotas for maximum and optimum sustainable yield of certain fisheries as well as the status and dynamics of the populations and recommendation of administration and conservation measures.
The whaling issue, as an example, is no longer a cultural, sustainable use or basic food issue it is about giving whales the holy status of western sacred cows, because animal rights groups have formed the collective conscience of the public opinion into believing that these animals are more human than humans.

 Build Sustainable Fisheries
Overfishing is a rate or level of fishing mortality that jeopardizes the capacity of a fishery to produce the maximum sustainable yield on a continuing basis.
Optimum yield is defined as the amount of fish which will achieve the maximum sustainable yield, as reduced by any relevant economic, social, or ecological factor.
In the case of an overfished fishery, optimum yield has been defined as that amount of fish which will provide for rebuilding of the stock to a level which will support the maximum sustainable yield.

 THE IMPACT OF DRIFTNET FISHING ON SUSTAINABLE FISHERIES
Sustainable fisheries are sustainable because they are very focused fisheries, catching the target species and little else.
Management requires that fishing effort be controlled so that no more and preferable less than the maximum sustainable yield (MSY) of the target population is caught during the year by all fishermen fishing on that population.
Since maximum sustainable yield is difficult to pinpoint and must also take other sources of mortality into consideration, it generally is safer to take the optimum sustainable yield (OSY) of a population, which is less that MSY.

 IWMC.org - 2nd Symposium - Issues of Relevance - Cultures & Traditions
Although management measures are essential for the long-term conservation of fisheries resources, and to ensure optimum sustainable yields, they are inevitably unpopular with those who have previously enjoyed unrestricted access to the resource.
In order to provide fisheries managers with the basic research findings required for defining goals such as optimum sustainable yield, total allowable catch and maximum yield per recruit, research programme have, by necessity, evolved from predominantly natural history and descriptive biology to more mathematically oriented task of resource assessment and population dynamics.
The realization that many resources have already declined past the point of optimum sustainability has necessitated assessment of methods for rehabilitation of depleted stocks and restoration of damaged habitats.

sustainable development stresses balancing human needs with the carrying capacity of the environment, practical issues arise as to how resource management---given the bias for effort reduction---could lead to an increase in incomes.
The Sustainable Livelihoods Approach (SLA) is another framework or analytical tool which highlights the expansion in assets or capital in the conduct of development work.
One of the major insights gained from this participatory research is the appreciation that fishing households and communities maximize a mixture of existing assets (referred to in the research as “strengths”), particularly natural and social capital, to minimize impacts of changing natural and social conditions (referred to as “vulnerabilities”).

The best sustainable yield, for the combined purposes of the fishing industry, of conservation, and of the nation as a whole.
A fishery in which, following a period of "full development", annual yields have declined steadily and significantly for a number of years and is now yielding much less that its historical maximum production.
While the causes of "senescence" could be many, it is usually assumed that overfishing is the main one, combined or not with unfavourable climatic conditions.

The maximum sustainable hunting rate is achieved when the largest number of animals are breeding at the fastest possible rate.
Harvesting strategies are usually set at a rate lower than this - the optimum sustainable yield.
A simple example being the ban on fox hunting which from above is simply regarded as being a method for achieving the optimum sustainable yield.

 ENB:07:24
The FAO representative said that the principle of Maximum Sustainable Yield (MSY) was adopted in UNCLOS as a target for development or rebuilding of resources that would be efficient for humans and safe for the resource.
But, with an imperfect knowledge of fish population dynamics and incomplete understanding of socio-economic dynamics, using MSY as a management target is neither efficient nor safe.
It was noted by some that the Russian proposal artificially disintegrates measures to protect straddling fish stocks, since it refers to long-term sustainability for straddling fish stocks and to optimum utilization for highly migratory fish stocks.

 Fishery Management Methods: Are Sustainable Fisheries Possible?
Maximum Sustainable Yield (MSY) is the largest annual catch of a particular species that fishermen can take continuously without over fishing it.
The problem with MSY as an indicator of the health of the fishery is that we never know what MSY is until we have over fished the stock.
Optimum Sustainable Yield (OSY), as it is now defined in the federal Sustainable Fisheries Act, is MSY minus a precautionary fudge factor to protect the stock from over fishing.

Coillte's policy is to harvest the optimum, sustainable yield of timber from its forests having regard to the protection of other forest values and to the requirements of its customers.
Forest management is a complex business and a wide range of factors must be taken into account in arriving at decisions about which forests should be harvested, when and by what method.
The principal requirement in regard to the sustainability of the timber resource is to ensure that, on average, the volume of timber harvested in any one year does not exceed the amount by which the volume of timber in the forest increases in one year.
