According to ROC law, when a ship takes a foreign registry, when its catch is sent back to Taiwan, it is treated as imported, and customs taxes must be paid. This is a heavy burden. Moreover, to prevent the industry growing excessively and exhausting resources, the government gives only a limited number of licenses. Ships may be scrapped and replaced, but no new ones may be added.
根據我國法令，一旦入籍成為外國船，漁獲回台就只能當作貿易進口，要課徵進口稅，這將增加漁業界很大的負擔；此外，為了避免產業規模過大造成海洋資源耗竭，政府發給每艘漁船一張執照，只能淘汰重建，不能另造新船。
