ABSTRACT

These beds are only from 1,000 to 1,050 meters long by about 300 meters broad, while the Huntje Bank is more than 1,800 meters long by about 900 broad. The speedy extension of oysters in the Lim Fiord has taught us that young swarm-oysters can wander from 4 to 8 kilometers away from their home-bed before they become attached to any object. So if the oyster-bank is of small extent, the young oysters are in danger of swimming out beyond the limits of the bed and settling upon unsuitable ground, and thus of being destroyed in much larger numbers than upon a larger bed. Of such broods of swarm-oysters the large banks will retain many more than the small beds; and if upon both all other conditions are the same, a much larger number of young will grow to maturity upon those beds which have a large extent of surface than upon the smaller beds.
