[23] Worldwide, about one-third of fish stocks are being fished at biologically unsustainable levels. [26]
Illegal and unreported fishing contributes to the reduction in fish stocks and hinders the ability for fish populations to recover. It is believed that between 10 billion and 23 billion instances of illegal and unreported fishing happen annually, with communities in developing countries being more likely to partake in these illegal activities.

Constant catch and constant fishing mortality are two types of simple harvest control rules.
