The traditional extensive culture of mullets together with other euryhaline species in embanked brackish waters still continues to be an important culture system, accounting for a good proportion of present-day production.
Culture in more easily manageable ponds is an improvement on the traditional system. The mullets are generally raised together with other species; for example, in Hong Kong mullets are cultured in combination with Chinese carps, in Taiwan with Chinese carps and tilapia, in Israel with the common carp and tilapia, and in India with milkfish, pearlspot (Etroplus suratensis) and other estuarine species. The milkfish ponds of the Philippines and tambaks of Indonesia (fig. 21.4) have a certain percentage of grey mullets, although there have been doubts about the suitability of the combination, due to the competing nature of their food habits.
Grey mullets have been transplanted to develop capture fisheries in certain areas. A notable example is the successful transplantation of mullets from the Black Sea into the Caspian Sea. Lake Quaroun and Lake Marut in Egypt and Lake Tiberias (Lake Kinneret) in Israel have been successfully stocked with mullets. M. capito has been reported to breed in Lake Quaroun (Wimpenny and Faouzi, 1935).
