Intrinsic post‐ejaculation sperm ageing does not affect offspring fitness in Atlantic salmon
Abstract Post‐meiotic sperm ageing, both before ejaculation and after ejaculation, has been shown to negatively affect offspring fitness by lowering the rate of embryonic development, reducing embryonic viability and decreasing offspring condition. These negative effects are thought to be caused by...
