dc.description.abstract | The probability of cod (Gadus morhua) and ling (Molva molva) to encounter a fleet of four
gillnets (110m) set within a fixed survey area of 600x600 m2 and soaked for a period of 12 h
(1800-0600 hrs) is calculated on the basis of in situ observations of fish movement and
random simulated start positions and setting directions of a fleet of gillnets. The movements
of cod and ling, which were tagged by allowing them to voluntarily swallow bait-wrapped
transmitters close to the sea bed, were studied by means of a stationary positioning system.
The expected number of encounters per fish for the fleet of gillnets varied between 0.127 and
0.626 for cod and 0.077 and 0.614 for ling with a fish density of three fish per 0,1 (n.mile)^2
