Photoperiod control of puberty in farmed fish: Development of new techniques and research into underlying physiological mechanisms

Strategies to delay puberty in fishfarming - A research project supported by the EC

The project is now finished.

Results, discussion, summary and dissemination

The current project has provided new fundamental knowledge on the cellular, molecular and endocrine
events that lead to onset of puberty in salmonids and sea bass, as well as applied knowledge on puberty
control in farming by improved understanding on how various photoperiod regimes, light intensities and
spectral composition of light affect the light perception and ultimately the onset and completion of puberty.
Moreover this has been put into the context of the interactions between photoperiod treatments, somatic
growth, adiposity and genetic background of the fish in arresting, delaying or promoting puberty.
