在挪威西海岸的养鱼场海水网箱附近经常可以观察到野生鱼，特别是绿鳕鱼（Pollachius virens L.），并且众所周知，这些鱼以过量的鲑鱼饲料颗粒为食。为了调查在养殖场的停留时间和随后的迁徙模式，在 1990 年 11 月至 1991 年 11 月期间，在挪威卑尔根附近的奥斯特沃尔海洋研究站的海水网箱设施中，对这些海龟进行了标记并每月释放一次。总共有 2607 个 saithe 被标记。标签回收的初步结果表明，赛特可以在农场网箱附近停留几个月，然后再离岸迁移到北海、设得兰群岛、法恩群岛和伊兰群岛。 ~--------------------, '
Wild fIsh, particularly saithe (Pollachius virens L.) are commonly observed in the vicinity of fIsh farm sea cages on the Norwegian west coast and the fIsh are known to feed on excess salmon food pellets. To investigate residence time at the farm site and subsequent migration pattern, saithe were tagged and released once monthly during the period Nov 1990 to Nov 1991 at the sea cage facility of the Austevoll Marine Research Station, near Bergen, Norway. A total of 2607 saithe were tagged. Preliminary results from tag recoveries show that the saithe can stay in the vicinity of the farm cages for several months before offshore migration to the North Sea, Shetland, Farne Islands and Ieeland. ~-------------------, '
