Wild broodstock were adapted to captivity, and good-quality spawns were obtained in 2009-2010, after GnRH treatment. In 2012, the F1 meagre (3years old) spawned naturally at IPMA's Aquaculture Research Station facilities. From each spawning event, the following parameters were determined: number of floating and non-floating eggs, egg size, hatching success and larval total length. Eggs size and percentage of hatching obtained from F1 breeders (1.04±0.10mm and 90.5±6.4%) were significantly higher when compared with wild breeders (0.97±0.13mm and 17.0±12.7%). Although wild breeder spawns exhibited 2.7±0.2mm for larval total length, F1 breeder spawns presented 2.6±0.2mm. The wild and F1 breeder spawns exhibit a good egg and larval quality, indicating a promising starting point for a successful meagre hatchery production.
