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.

The concept of maximum sustainable yield is not always easy to apply in practice. Estimation problems arise due to poor assumptions in some models and lack of reliability of the data. [8] [25] Biologists, for example, do not always have enough data to make a clear determination of the population's size and growth rate. Calculating the point at ...
Advertisements in daily newspapers whose readers are educated and interested in sustainability issues, as well as in magazines promoting a sustainable lifestyle contribute to raise consumers' interest in sustainable products and services. Posters on the other hand are often used for social marketing campaigns. [24]
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time. [2]
Ecological yield is the harvestable population growth of an ecosystem. It is most commonly measured in forestry : sustainable forestry is defined as that which does not harvest more wood in a year than has grown in that year, within a given patch of forest .
Scientists say 7,500 tons annually is the sustainable limit, yet the fishing industry continue to harvest 60,000 tons. In wild fisheries, overexploitation or overfishing occurs when a fish stock has been fished down "below the size that, on average, would support the long-term maximum sustainable yield of the fishery". [22]
In environmental science, optimum sustainable yield is the largest economical yield of a renewable resource achievable over a long time period without decreasing the ability of the population or its environment to support the continuation of this level of yield, and enables an ecosystem to have a high aesthetic value.
Green growth is a concept in economic theory and policymaking used to describe paths of economic growth that are environmentally sustainable. [1] [2] [3] It is based on the understanding that as long as economic growth remains a predominant goal, a decoupling of economic growth from resource use and adverse environmental impacts is required.
