Fish stocks are subpopulations of a particular species of fish, for which intrinsic parameters (growth, recruitment, mortality and fishing mortality) are traditionally regarded as the significant factors determining the stock's population dynamics, while extrinsic factors (immigration and emigration) are traditionally ignored. Stocks fished ...
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).
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.
Seafood Watch is a sustainable seafood advisory list, and has influenced similar programs around the world.It is best known for developing science-based seafood recommendations that consumers, chefs, and business professionals use to inform their seafood purchasing decisions.
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.

Sustainable seafood advisory lists and certification are programs aimed at increasing consumer awareness of the environmental impact and sustainability of their seafood purchasing choices. California-based Seafood Watch and Marine Conservation Society 's fish online are some of the best-known guides.
Catch shares provide long-term secure privileges to participants and, in theory, an incentive for efficient, sustainable use of fish stocks. [2] Actual outcomes in terms of efficiency and ecological sustainability are varied, based on design and implementation of the program. Catch share programs generally fall into two categories.
Sustainable seafood is from either fished or farmed sources that can maintain or increase production in the future without jeopardizing the ecosystems from which it was acquired. The sustainable seafood movement has gained momentum as more people become aware of both overfishing and environmentally destructive fishing methods. Fish farming can ...
