The influence of the catch on the times expended on respective steps of fishing works conducted by the Danish seiners during the Alaska pollack fishery in 1964, were examined as the first step of this series. And the results obtained are summarized as follows: 1. The time to complete a haul (tc, in min.) increased with catch (x in tons), keeping the following relation: tc=91.06+3.17 x. 2. The increase in the time to complete a haul with catch was chiefly due to the same relation found in the hauling-brailing time (th in min.). This was as follows: tk=47.73+3.16 x. 3. The laying time and sinking-pulling time had no clear relations to catch. 4. The influence of the catch on the interval between succeeding hauls could be seen in the tailing of the distribution in the direction of the classes of long intervals-conspicuous in the hauls with poor catch and less conspicuous in the hauls with good catch.
