Broodstock - transcription profiling of maternal RNA in Atlantic cod eggs and embryos after female broodstock stress

ABSTRACT: A stable supply of viable eggs and embryos is crucial for successful farming of Atlantic cod. Broodstock stress can have negative effects, but little is known about the molecular mechanisms that cause abnormal development. Maternally transferred mRNAs have been shown to be essential for normal development, and stress may therefore influence their expression and the subsequent embryonic development. We investigated if mimicked stress in prespawning Atlantic cod females affects mRNA concentrations in eggs and embryos, and if this can be linked to egg/embryo viability, and if we could identify potential molecular markers for stress and egg/embryo viability. Consequently, 3 weeks prior to expected peak spawning, 20 females were intraperitoneally implanted with either cortisol-containing or cor
