Obiettivo Recent research has demonstrated the feasibility of cultivating intensively pikeperch Sander (Stizostedion) lucioperca, a valuable fish under increasing demand for both the consumption (large size fish, 2-4 kg each) and the restocking (0+ and 1-year old fish) markets. However, the supply of eggs and larvae is still largely dependent on the spawning of wild breeders or captive fish held in ponds during the maturation process. Production of pikeperch eggs and larvae is thus seasonally restricted and extremely variable in quality and quantity. The main objective of the project is to secure the supply of high quality eggs and larvae of pikeperch. To reach that goal, the following specific objectives have been identified :1. Securing continuous supply of eggs and larvae by developing out-season spawning technology by temperature and photoperiod control.2. Investigating the effects of different husbandry and dietary variables on reproductive physiology and nutritional status of breeders and related effects on spawning performances, gamete and larval quality.3. Comparing the quality of eggs and larvae from breeders stocked in various environments (tanks vs cages vs ponds) and definition of a referential for the quality of pikeperch eggs and larvae.4. Setting efficient procedure of broodstock and larval rearing to produce pikeperch sex-reversed males and, in a second step, all-female populations of juveniles.To compare efficiently the effects of the different variables on gamete and larval quality, standardized larval rearing conditions will be precisely defined at the onset of the project and applied to all experiments.
