Diver surveys of scallops were conducted in 2009 and 2010 at selected recreational fishing areas in the Coromandel stock (SCA CS), marking the fourth and fifth in a 2006–10 series of annual surveys of these areas. The abundance and size structure of scallops varied markedly among areas. Scallop densities in areas open and closed to commercial dredging were compared using data from the 2006–10 diver and dredge surveys. Abundance in commercial and some recreational areas seems to have varied in similar ways but it is difficult to draw firm conclusions about the nature of this relationship.
