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 ...
Today, due to the pre-allocation of catch that accompanies IFQs, the season lasts nearly eight months and boats deliver fresh fish at a steadier pace. However, halibut stocks have been in continuous decline for over a decade, as poor stock assessments leading to overfishing have caused a substantial decline in biomass. Additionally, despite the ...
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.
The Common Fisheries Policy was created to manage fish stock for the European Union as a whole. Article 38 of the 1957 Treaty of Rome, which created the European Communities (now European Union), stated that the common market shall extend to agriculture and trade in agricultural products. Agricultural products in the treaty meaning the products ...

Straddling stocks – A term defined by the United Nations as "stocks of fish such as pollock, which migrate between, or occur in both, the economic exclusion zone of one or more states and the high seas". They can contrasted with transboundary stocks. A ...
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).
According to marine ecologist Chris Frid, the fishing industry points to pollution and global warming as the causes of unprecedentedly low fish stocks in recent years, writing, "Everybody would like to see the rebuilding of fish stocks and this can only be achieved if we understand all of the influences, human and natural, on fish dynamics."
Fish stocks in international waters - Oceans remain one of the least regulated common resources. [1] When fish are withdrawn from the water without any limits being imposed just because of their commercial value, living stocks of fish are likely to be depleted for any later fishermen. This phenomenon is caused by no incentives to let fish for ...
