Abstract
A stratified bottom trawl fish survey was carried out in the

Spitzbergen and Bear Island regions from 9 September to 5 October

1985. On 30 out of 108 trawl stations, Chlamys islandica were

caught as a by-catch, and samples from 8 stations have been

measured for height, length, width, total wet weight, and wet

weight of the total content, muscle and gonads. The sex has been

determined and the number of zones in the ligament counted.

C. islandica were caught on stations with depths from 48m to 525m.

The scallops from the deepest stations seemed to be somewhat

younger and smaller. The adductor muscle made up 19-24% of the

total weight of cleaned shells. The northernmost sampled station

(N 79°29') had the oldest scallops, but the zones in the

ligaments from this station were difficult to read because of the

often bad consistency of the ligament.
