Gonatus fabricii (hereafter gonatus) is a pelagic squid, widely distributed in boreal and subarctic waters. Material for the present investigation has been collected since 1970 mainly in the Norwegian Sea and adjacent areas during postlarval and 0-group fish surveys during late summer and autumn. Earlier material used included stomach contents from hooded seals caught in the Jan Mayen area, and from bottlenose whales taken east of Iceland and off Labrador. Gonatus larvae were also taken in plankton net hauls at Station M at 66°00'N 02°00'E. Gonatus with mantle lengths 6-20 mm were found in the Norwegian Sea between December and July, 25-45 mm in February - September, and 55- 100 mm in May - September and in December. Larger squid, mantle lengths 13-28 cm, were only taken from stomach contents of hooded seals and bottlenose whales. During 1978 gonatus with mantle lengths 15-45 mm were very abundant in the surface layers of the central and eastern Norwegian Sea during summer and autumn, up to 2000 specimens (5000 ml) were taken in half hour hauls with a Harstad trawl, 18 x 18 m opening. Juveniles also became stranded along the coast of eastern Finnmark in North Norway during the autumn. The correlation between rostral length (RL)of the beak and mantle length of gonatus has been roughly calculated. In stomach contents of bottlenose whales caught off Labrador during May - June 1967, the calculated mantle lengths of gonatus varied from 6 cm to 30 cm, mostly 13-28 cm. In the Norwegian Sea spawning and hatching of gonatus probably occur from December to July, with the peak in April - June. The main areas of spawning may coincide with localities where bottlenose whales are abundant as can be seen from catch statistics, e.q. off eastern Iceland, Møre, Vesterålen and West of Spitsbergen (Fig. 7). The life cycle of gonatus is probably closely connected to the current system of the Norwegian Sea and adjacent seas. A fishery for juvenile gonatus should be tried in these areas, chiefly during April - August, using trawls, lights and dip nets or pumps; for larger squid, jigging gear combined with lights should be used.
