PIT 标志技术在鱼类资源保护中的应用研究.

PIT (passive integrated transponder) marker has been widely used in fish population dynamics, proliferation and release, habitat selection, fish passage facilities and other research fields due to its advantages of large information storage, durable and reliable, rapid identification, stable performance, uniqueness and small size. It has become a major vehicle for fish conservation research. In this paper, the working principle of PIT marking technology is introduced, and the applied research of PIT marking technology in fish resource protection at home and abroad from 1991 to 2020 is summarized. This study discusses the effectiveness of PIT marking technology in research on fish population dynamics, fish passage facilities, proliferation and release, and habitat selection. By comparing the application and research of PIT marking technology at home and abroad, combined with the actual needs and research of domestic fish resources protection, analyzes the reference effect of PIT marking technology application from abroad, points out the development direction of PIT marking technology application research in China and proposes to strengthen the long-term monitoring of PIT marking technology in fish passage facilities, fish proliferation and release, fish population dynamics, and fish habitat selection, improve the technical level of PIT marking technology in fish resource protection research, formulate technical specifications for PIT marking applications, and establish PIT marking monitoring network system to meet the needs of research, conservation, and management of fish.
