Abstract

マグロ延縄漁船における人員確保の困難さを緩和する一方策として,労働時間の均等化が考えられる。海洋水産資源開発センター傭船開発丸が, 1995-96年度に行った392回の操業中,直線に沿って投縄した139回の資料を用い, 1延の鉢数・ 1鉢が被う距離・風の船首尾方向と正横方向の分力を説明変数として投縄・揚縄速度を記載する式を求めた。その式を用いると74%の例について, 30分以内の誤差で揚縄時間が求められた。これらの説明変数は調整か予測可能であるので,それらから速度を求めて1延の鉢数を調整すれば,作業時間の均等化は可能である。

The possibility of equalizing the length of the working hours of a tuna longliner was sought by examining therelation of working speed of the longliner to the adjustable and predictable factors observable in the records for139 strings extended along a straight course, which were chosen from the records for 392 strings conducted bya research ship during 2 fiscal years. It was found that the time for retrieving work for the respective stringscould be estimated for 74% of the strings, when a difference of 30 min was set as the permissible range.Namely, it is possible to adjust the length of the working hours by changing the length of a string according tothe predicted speed from the number of sections, the distance covered by a section and the wind speed.
