Question: What is maximum sustainable yield in environmental science?

Maximum sustainable yield (or MSY) is the maximum catch that can be extracted from a fish or other population in the long term.

What is sustainable yield in environmental science?

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. A sustainable society…

What is the maximum sustainable yield for a resource?

The maximum sustainable yield (MSY) for a given fish stock means the highest possible annual catch that can be sustained over time, by keeping the stock at the level producing maximum growth. The MSY refers to a hypothetical equilibrium state between the exploited population and the fishing activity.

What is meant by sustainable yield?

The sustainable yield of renewable natural resources is traditionally defined as the extraction level of the resource which does not exceed the growth. Context: The sustainable yield refers to total fellings and not only to timber removed for own consumption and use. …

How do you find the maximum sustainable yield?

If stock size is maintained at half its carrying capacity, the population growth rate is fastest, and sustainable yield is greatest (Maximum Sustainable Yield). K = unfished stock biomass at carrying capacity r = intrinsic rate of stock growth.

What do you mean by maximum sustainable yield?

Maximum sustainable yield (or MSY) is the maximum catch that can be extracted from a fish or other population in the long term. Given that the term was coined before WWII, one could say that fisheries scientists thought about sustainability way before it became fashionable, but they did not have sustainability in mind.

How is maximum sustainable yield related to carrying capacity?

The maximum sustainable yield (MSY) for a population is exactly equal to half of its carrying capacity.

What is maximum sustainable yield quizlet?

maximum sustainable yield. The maximum usable production of a biological resource that can be obtained in a specified time period without decreasing the ability of the resource to sustain that level of production. maximum sustainable-yield population.

What affects maximum sustainable yield?

MSY is based on the ecological concept of sigmoid population growth toward the carrying capacity of the ecosystem for the respective species. The surplus in numbers and biomass produced for population growth can be caught sustainably and reaches a maximum (MSY) at intermediate population size.

Who coined the idea of maximum sustainable yield?

Maximum sustainable yield

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.

Why is sustainable yield important?

Sustainable yield is an important component of sustainable forest management. In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock.

What is the difference between yield and sustainable yield?

Safe yield has functional relation with water withdrawal and its temporal pattern while the sustainable yield caters long term availability of water resource through replenishment in dry season and withdraw in wet season. Sustainability is a very complex concept.

What is the difference between MSY maximum sustainable yield and Mey maximum economic yield )?

In fisheries terms, maximum sustainable yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions. Relating to MSY, the maximum economic yield (MEY) is the level of catch that provides the maximum net economic benefits or profits to society.
