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.
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.

Fish are harvested by commercial fishing and aquaculture. Stocks fished within biologically sustainable levels decreased from 90% in 1974 to 62.3% in 2021. [5] The world harvest increased over the 20th century and, by 1986, had stabilized around 85–95 million metric tons (94 × 10 ^ 6 –105 × 10 ^ 6 short tons) per year. [9]
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 [1] When fish are withdrawn from the water without any limits being imposed just because of their commercial value, living stocks of fish are likely to be depleted for any later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.
