The map key classifies Atlantic cod spawning areas as ‘recurrent’, ‘occasional’, ‘rare’ and ‘unfavourable’. This layer updates the existing (Coull et al., 1998) spawning map for Atlantic cod (Gadus morhua) also available on NMPi, by providing finer granularity to the likely Atlantic cod spawning areas. The Coull et al., (1998) maps have been used for more than a decade to ensure that appropriate protection is afforded to sensitive areas from disturbance.

The importance of environmental influences on spawning distribution was then examined using General Additive Models (GAMs). Environmental variables such as depth, slope, distance to coast, springtide (tidal currents), sediment type, temperature and salinity were considered. This output serves as an update to the existing (Coull et al., 1998) spawning map for Atlantic cod (Gadus morhua) also available on NMPi, by providing finer granularity to the likely Atlantic cod spawning areas.
