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 ...
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.

Climate change is modifying fish distributions [6] and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. [7] The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector.
MSY has been especially influential in the management of renewable biological resources such as commercially important fish and wildlife. In fisheries terms, maximum sustainable yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions. [22]
Many species of fish including grass carp and the suckermouth catfish help clean bodies of water by eating algae and other green organisms. [16] Algae can take over stagnant ponds, attracting insects and making lakes, rivers, and ponds unpleasant to look at. To treat them, many individuals will choose to stock certain species of fish.
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.
YouTube Kids has faced criticism from advocacy groups, particularly the Fairplay Organization, for concerns surrounding the app's use of commercial advertising, as well as algorithmic suggestions of videos that may be inappropriate for the app's target audience, as the app has been associated with a controversy surrounding disturbing or violent ...

Fish stock (food), liquid made by boiling fish bones with vegetables, used as a base for fish soups and sauces; Fish stocking, the practice of raising fish in a hatchery and releasing them into a river, lake, or ocean; Stockfish, unsalted ...
