１２月２３日　オイル交換の8永盛丸　水揚げの51日光丸(Oil change on the No. 8 Eiseimaru and landing on the No. 51 Nikkomaru)

新港には映像順に３隻の鰹船がいる。 第８永盛丸　第１１日光丸　第51日光丸 第８永盛丸は２２日南方鰹３２０トンを水揚げし、今日はオイル交換をしている。 第１１日光丸は明日２４日南方鰹３８８トンを水揚げ予定。 第51日光丸は現在南方鰹３２３トンを水揚げ中。 ８永盛丸と１１日光丸の鰹サイズを見ると価格の高い1.5kgオーバー 　2.5kgオーバーの取れ高が厳しい。 南方の水温が高く成長が早いのだろうか？　　考えすぎか？ There are three skipjack tuna boats at Shinko, shown in the order shown in the video. Eisei Maru No. 8, Nikko Maru No. 11, Nikko Maru No. 51 Eisei Maru No. 8 landed 320 tons of southern skipjack tuna on the 22nd and is having an oil change today. Nikko Maru No. 11 is scheduled to land 388 tons of southern skipjack tuna tomorrow, the 24th. Nikko Maru No. 51 is currently landing 323 tons of southern skipjack tuna. Looking at the size of the skipjack tuna on Eisei Maru No. 8 and Nikko Maru No. 11, they are over 1.5kg, which is the more expensive size. The catch of 2.5kg or over is tough. Is it because the water temperatures in the south are higher and they grow faster? Or am I overthinking it?
