    Abstract

    Restrictions on size of fish that are caught are used as one of a number of measures considered for the sustainable management of fish stocks all over the world. The simple logic behind this conservation principle is to provide chance to the younger ones to grow, mature and reproduce at least once and contribute to the population before they are taken away in the catch. In many countries, there are legally implemented size (or length) limits for different species in the catch in the fishery including recreational fishing. Such size limits are arrived based on scientific research about the species especially its reproductive features. Though in most cases size restrictions are for the minimum size, there are restrictions on maximum size in some species were larger individuals contribute more to the population growth (example: Asian seabass younger ones are males and become females and spawn when they grow larger).
