The best scallop bed was found in Balsfjord, near Tromsø, covering 32 ELENA GUIJARRO GARCIA 70,000–100,000 m2. Most shells were >60 mm SH and all individuals reached maturity at 50 mm SH (Wiborg, 1963a). Density of scallops >65 mm SH was 33 individuals mÀ2 (Venvik and Vahl, 1979), and it was estimated that the Balsfjord scallop beds could support a fishery of 500–1000 tonnes yrÀ1. In this location, CPUE reached 80 kg minÀ1 when using a 9-ft wide Icelandic dredge and 67% of the catch were scallops >65 mm SH (Venvik, 1982).

The scallop beds surveyed in 1986 are shaded in grey. ) Besides, these beds seemed to be self-recruiting, meaning that recovery time would be very long (Anonymous, 1992). Nevertheless, commercial and experimental dredging continued until 1995, mostly in Bjørnøya and MoVen.
Engelstoft supplied some information on management of the Greenlandic scallop stock, G. G. Þo´rarinsdo´ttir helped with some of the Danish reports and K. Gunnarsson gave good advice. A. A.
