What do you mean by maximum sustainable yield?

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 maximum sustainable yield in environmental economics?

The maximum sustainable yield (MSY) is defined as the largest yield one can harvest from the resource over an indefinite period. From: Encyclopedia of Energy, Natural Resource, and Environmental Economics, 2013.

What is biomass maximum sustainable yield?

Biomass for the maximum sustainable yield. The biomass that would provide the highest long‑term average catch (or maximum sustainable yield, MSY) of a fish stock. Back to Glossary.

What is the key ideas of maximum sustainable yield?

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.

What happens if a fishery is overexploited?

It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.

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 how it differ from 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.

Why sustainable aquaculture is a must?

The goal of sustainable aquaculture is to provide a continued supply of farmed aquatic nutrients beneficial for human sustenance without harming existing ecosystems or exceeding the ability of the planet to renew the natural resources required for aquaculture production.

What fishing method is most destructive to oceans?

Bottom trawling
Bottom trawling, a fishing method that drags a large net across the sea floor, is extremely destructive, destroying as it destroys entire seafloor habitats including rare deep sea coral and sponge ecosystems that take decades to millennia to develop.
