BOTANY

Detailed explanation-1: -The maximum sustainable yield (MSY) is the maximum amount that can be taken without depleting the resource or population over the long-term. For example, the MSY for a forest is the amount of trees that can be removed while allowing the forest to naturally replace those trees.

Detailed explanation-2: -Maximum sustainable yield (MSY) is a theoretical concept used extensively in fisheries science and management. In fisheries, MSY is defined as the maximum catch (in numbers or mass) that can be removed from a population over an indefinite period.

Detailed explanation-3: -Maximum sustainable yield, a common objective of fisheries management, is the point beyond which a fishery tips into an unsustainable level (assuming fishing pressure remains the same) and that can ultimately lead to stock collapse.

Detailed explanation-4: -The term sustainable yield refers to the harvest of a specific (self-renewing) natural resource-for example, timber or fish. Such a yield is one that can in principle be maintained indefinitely because it can be supported by the regenerative capacities of the underlying natural system.

Detailed explanation-5: -Maximum Sustainable Yield (MSY) is a statement of two long-standing desirable goals of exploiting a population: (1) attaining the highest possible catch consistent with (2) the population persisting in perpetuity.
