Can you tell me how fishery regulations aim to keep sustainable fish populations?

Fishery regulations help to ensure that sustainable fish populations are maintained by managing how much fish can be harvested, from which waters, and by which methods. These regulations are designed to prevent overfishing and protect threatened species. Regulations may limit the type of gear used, the duration and length of fishing seasons, the amount of catch that can be taken, the size of fish that can be harvested, the number of vessels allowed to operate, the species or kinds of fish that may be caught, and the use of fisheries conservation efforts such as catch sharing or closures. Regulations can be used to increase sustainability in multiple ways, such as encouraging efficient and responsible practices to maximize catch, providing more time for stocks to reproduce, protecting vulnerable habitats and species, reducing the amount of bycatch, and discouraging illegal fishing. Furthermore, effective management reduces the risk of catastrophic collapse of ecosystems by avoiding overcrowding of aquatic species and reducing competition between industries.
