[生物研究] 全球首創利用鏢旗魚法 進行標識放流研究

台灣東部鏢旗魚漁法源自日領時期的日本千葉縣及和歌山縣漁業移民，鏢手必須頂著滔天巨浪站上鏢台，靠著眼力巡視四周大海追尋旗魚的蹤影，一旦瞥見旗魚，便出手鏢魚。台東成功地區漁民迄今仍用這種技術捕捉旗魚。

最近水試所東部海洋生物研究中心為了了解東部大型洄游魚類的洄游和棲地之謎，也利用這種鏢旗魚漁法在台東縣成功鎮外海，將上脫型衛星標識器鏢置在雨傘旗魚魚體背部，藉此來記錄雨傘旗魚的行蹤。以往旗魚類標識放流研究的試驗魚，多半來以曳繩釣及定置網所獲，但因漁撈捕捉過程不免對魚體造成傷害，所以經常發生試驗魚在標識後不久就死亡的情形，而這次的研究首次利用鏢旗魚漁法，直接將上脫型衛星標識器成功的鏢置於雨傘旗魚魚體上，使傷害降到最低。

[Biology] Globally New Skill of Tagging and Releasing Experiment: Harpooning!

In Eastern Taiwan, harpooning skill is widely applied, especially by the fisherfolk of Chenggung Area, Taitung County, when fishing spearfish. The harpooner has to stand on the harpooning box ahead of the boat, observing the fish in wild waves. As soon as the harpooner glances the fish, he has to shoot the harpoon at the fish immediately. This special skill is developed from the Japanese migrants from Chiba-ken and Wakayama during the Japanese colonization period.

Lately, Fisheries Research Institute, Council of Agriculture, Executive Yuan (COA-FRI) applied the harpooning skill to harpoon the pop-up satellite tag, PSAT, onto the back of the Sail Fish in the outside sea of Chenggung Township, Taitung, in order to study the migration and the habitat of the large migration fish in Eastern ocean. The traditional tagging and releasing experiment usually applied trolling or set net and caused damage to the fish body. The tagged fish of that skill usually died soon after released. The successful harpooning skill not only succeeds in putting the PSAT onto the spearfish, but protects the tagged.
