Sample text

This was a priority, as at the beginning of the fishery some vessels lacked onboard mechanical processing and the catch had to be stored for several days (Anonymous, 1988; Larsen, 1991). The eVect of dredging on the benthic communities was also investigated. No changes were detected in Jan Mayen after the closure of the fishery, apart from an increase in Ophiura robusta. In the Svalbard area, although the dominant species were the same in 1987 and 1988, the number of species and diversity decreased after dredging started.

There are no quotas for the fishing grounds discovered after 1995, but the Greenland Institute of Natural Resources advises a total catch of 2000 tonnes for all West Greenland. This figure is based on landings during the last 10–15 yr and the stability of catches (Engelstoft, personal communication), and it seems to be appropriate, as there have been no major fluctuations in overall annual landings (Table 3). 4. Research There are old records of scallop beds found in West Greenland, dating from the end of the nineteenth century, as cited in Posselt (1898) and Jensen (1912).

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.
