grounds have been defined in the East Anglia THREE site and the offshore cable corridor for thornback ray and spurdog.


57.


In the case of thornback ray and spurdog, there is currently insufficient data on the occurrence of egg-cases or egg-bearing females in the spawning season with which to delineate spawning grounds. However, it is considered that these are likely to broadly overlap with nursery grounds (Ellis et al. 2012).


58. Most of the species with defined spawning grounds in the area are pelagic spawners, which release their eggs in the water column. The exceptions to this are herring and sandeel (Ammodytidae) which are demersal spawners, as well as some elasmobranch species including lesser spotted dogfish, thornback ray and blonde ray which lay eggs on benthic substrates (William 1997; Serena 2005; Compagno 2001).


59. Detailed information on the distribution of spawning and nursery grounds of the species described above, together with information relating to their ecology, is provided in section 11.5.5, Appendix 11.2.
