Phenotypic plasticity and the epigenetics of teleost development
Work Package (WP) 4
Salmon larva during experiment
The environment can affect phenotypic traits (e.g. growth, sex determination) through epigenetic mechanisms, such as DNA methylations and histone modifications. Recent studies in several teleost fish species showed that different temperature regimes during early ontogeny influences muscle growth and cellularity. In WP4 we investigate the effect of different temperature regimes during early ontogeny on muscle development in Atlantic salmon and cod. Using a variety of epigenetic, transcriptomic and histological analyses we aim to gain enhanced insight and biological understanding in the mechanisms underlying phenotypic plasticity and epigenetic processes. For aquaculture purposes, as well as for management of wild and cultured populations which may encounter future climate changes, this is of high priority.
