Summary

The Sparidae is a cosmopolitan family, and sparid fishes can be found and reproduced in both temperate and tropical seas around the world. Most of the members of this family are sequential hermaphrodites—either protogynous, such as the red porgy (Pagrus pagrus), or protandrous, such as the gilthead sea bream (Sparus aurata)– but gonochoristic species also exist, such as the common dentex (Dentex dentex). Fish in this family have a long spawning season, ranging between 60 and 150 days, and spawn daily or in a highly cyclical fashion. Fecundity is very high ranging between 0.4 and 3.2×106 eggs kg−1 of female body weight. The eggs are pelagic and transparent and have a diameter between 800 and 1,000 µm. Hormonal therapies have been developed to address the reproductive dysfunctions that exist in the early days of establishing captive wild or hatchery-produced broodstocks. At present, most Sparidae that are cultured commercially reproduce spontaneously in captivity and hatchery produced broodstocks have been developed and in some cases selected for traits of commercial importance.
