Stock identification is a field of fisheries science which aims to identify these subpopulations, based on a number of techniques.This concept is applied in sustainable development goal 14 where target 14.4 is measured a fish stock sustainability indicator 14.4.1. [2]
To improve their overfishing prevention programs, the NMFS has implemented the Fish Stock Sustainability Index (FSSI), which measures key stocks according to their overfishing status and biomass levels. Since the FSSI began the index has increased every year. [12] The act also has impacts on financial matters.
Sustainability can mean different things to different people. Some may view sustainable fishing to be catching very little in order for fish populations to return to their historical levels (represented by the upper left green area), while others consider sustainability to be the maximum amount of fish we can catch without depleting stocks any further (red dot).
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.

Fish stocks indicators, which is normalized as a 0–100 proximity-to-target score, with 100 representing "at target" and 0 being furthest from the target. Stock assessments provide fisheries managers with the information that is used in the regulation of a fish stock. Biological and fisheries data are collected in a stock assessment.
In fisheries terms, maximum sustainable yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions. [22] MSY aims at a balance between too much and too little harvest to keep the population at some intermediate abundance with a maximum replacement rate.
The Environmental Performance Index (EPI) is a method of quantifying and numerically marking the environmental performance of a state's policies, highlightning the degradation of the planet's life-supporting systems on which humanity depends. A world economy that continues to rely heavily on fossil fuels translates into ongoing air and water ...
The United Nations Fish Stocks Agreement (UNFSA), otherwise known as the Straddling Fish Stocks Agreement (formally, the Agreement for the Implementation of the Provisions of the United Nations Convention on the Law of the Sea of 10 December 1982 relating to the Conservation and Management of Straddling Fish Stocks and Highly Migratory Fish Stocks) is a multilateral treaty created by the ...
