The effect of photoperiod on growth and survival in early life was determined in the tropical batch spawning atherinopsid, pike silverside Chirostoma estor . The results demonstrate high sensitivity of newly hatched C. estor to photoperiod treatments up to 90 days post hatch shown by improved growth in mass (43%) under continuous illumination. This is accompanied by increased fat deposition, which suggests a critical interaction between different photoperiod‐mediated mechanisms. A thorough understanding of these mechanisms can help to optimize the development of aquaculture of C. estor and similar species.
