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.

[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.
