Photoperiod manipulation and growth of Atlantic cod ( Gadhus morhua )
Atlantic cod (Gadus morhua) placed under 24 hour illumination (LL) from 15 months post hatch (MPH), did not spawn at 2 years and only 7.2% were found to be spawning at 3 years. Ultrasound scanning however showed some gonad development from 22-28 MPH in the LL treated group. This data shows that cod...
