Available in PDF, EPUB and Kindle. Book excerpt: An ongoing cooperative project between the Bonneville Power Administration and the National Marine Fisheries Service was initiated in 1983 to evaluate the technical and biological feasibility of adapting a new identification system to salmonids. The system is based upon the passive integrated transponder (PIT) tag. This report discusses the work completed in 1985 and is divided into laboratory and field studies. All studies were conducted with the tag implanted into the body cavity of the test fish via a 12-gauge hypodermic needle.

In Phase I, sham PIT tags were injected into the body cavity of juvenile salmonids. Tagged fish ranged in weight from 0.8 to 43.9 g. Observations based on six tests, ranging in time from 19 to 99 days, indicated that the test site for injecting the tag was along the mid-ventral line in the area of the pectoral or pelvic fins. Tag retention of 99% (n = 400) and survival of 99% were achieved. Minimal tissue response to the tag was noted in both tag locations. In Phase II, a PIT tag detector system designed to detect and record the passage of juvenile salmonids was evaluated. By restricting the rate at which fish entered the monitoring tunnel to one fish per second, detection averaged 94.3% compared to 86.6% for multiple fish entry. In Phase III, a monitoring system designed to detect and decode adult fish tagged with a PIT tag was evaluated. The average detection and proper decoding of these tagged fish was 94.4% for 211 fish. Improvements in the detection system are recommended.

A new tag called the PIT (passive integrated transponder) tag measuring 7.5 mm long by 1.5 mm in diameter has a great potential for marking fish if it proves to be biologically compatible. A study was conducted to evaluate the potential of the PIT tag for marking salmonids. The objectives of the first year's research were to determine: (1) the anatomical areas in which the tag could be placed; (2) tissue response to the tag; and (3) tag retention. Juvenile coho, Oncorhynchus kisutch, and chinook O. tshawytscha, salmon and adult chinook salmon held at Manchester or Big Beef Creek, Washington, were used as test animals. Juvenile salmon were injected with sham PIT tags in the body cavity and opercular, dorsal, and caudal masculature. The fish ranged in length from 126 to 212 mm. Observations based on three tests, from 44 to 102 days long, indicated that the dorsal musculature and body cavity were the best locations to inject the tag from biological and social standpoints. Sham PIT tags were injected into the nose; body cavity; and opercular, dorsal, and caudal musculature of jack chinook salmon. The test was conducted for 23 days. Although all five anatomical areas were acceptable from a technical standpoint, the body cavity appeared to be the best area for tag placement. Initial test results with the Sham PIT tag were very encouraging. Apparently the PIT tag can be successfully injected into and carried by salmon, making it a potentially useful tool for fisheries biologists. 5 refs., 8 figs., 6 tabs.

Book excerpt: This report covers work performed by the National Marine Fisheries Service (NMFS) between 1994 and 1996 to develop a passive integrated transponder tag (PIT-tag) system to interrogate volitionally migrating adult salmon. A phased approach was adopted to realize this goal. The plan was to address basic electronic, mechanical, and hydraulic engineering questions in Phase I. In addition, several biological studies were initiated to provide basic information needed to design interrogation systems that minimize the potential risks to migrating adult salmon. The results obtained in Phase I will provide direction for the Phase II work involving the actual design and development of the extended-range PIT-tag interrogation system. Finally, Phase III will evaluate the biological responses of fish to the final design(s).

Available in PDF, EPUB and Kindle. Book excerpt: In 1983, the National Marine Fisheries Service (NMFS) began a multiyear cooperative research program with the Bonneville Power Administration (BPA) to evaluate a new miniaturized identification system that could be used with salmonids. The system is referred to as the passive-integrated-transponder (PIT) tagging and interrogation system. The program has focused on determining the effects of PIT tags on juvenile and adult salmonids, as well as the development and evaluation of tagging and interrogation methods. Earlier results of the program have been reported in annual reports and journal articles cited in this report. This report covers the work per formed from 1990 through 1993. For convenience, the report is divided into three sections: (1) Interrogation and separation systems at Columbia River Basin dams; (2) Systems development and evaluation; and (3) Information and technology transfer.

Book excerpt: This report covers our work during 1998 and 1999 (FY99) on a project to expand and improve technology for passive-integrated-transponder tags (PIT tags) throughout the Columbia River Basin. The National Marine Fisheries Service (NMFS) in cooperation with the Bonneville Power Administration (BPA) conducted the work. Timely and accurate information derived from PIT-tag technology is increasingly critical to resource stakeholders in assessing the effectiveness of efforts to enhance survival of juvenile and adult salmonids. Continued development of PIT-tag technology will enable researchers and fisheries managers to address issues expressed in the NMFS biological opinions for operation of the Federal Columbia River Power System (FCRPS) and the proposed Snake River Recovery Plan. The FY99 work was divided into individual projects that are covered separately in this report.

Available in PDF, EPUB and Kindle. Book excerpt: In 1983, a multi-year project to evaluate the technical and biological feasibility of adapting a new identification system to salmonids was established. The system is based upon a miniaturized passive integrated transponder (PIT) tag. This report discusses the work completed and is divided into laboratory studies, field studies, and systems development. All studies were conducted using a glass-encapsulated tag implanted into the body cavity of test fish via a 12-gauge hypodermic needle. Laboratory studies with juvenile chinook salmon, Oncorhynchus tshawytscha, showed that retention of glass-encapsulated PIT tags was 99-100% in fish weighing 3 g (mean weight) or larger. No adverse tissue response to the tag was noted. The survival of fish 5 g (mean weight) or larger was usually greater than 99%. However, fish ranging in weight from 2 to 4 g, or fish undergoing a physiological change such as smoltification may have a low mortality (usually less than 5.0%) after tagging. The mortality rate in the smaller fish was dependent upon tagging skill whereas mortality in smolting fish seemed dependent upon the level of stress. Growth comparisons between tagged and control fish indicated PIT-tagged fish had a slightly depressed growth rate at some measurement periods. The operational life of glass-encapsulated PIT tags implanted in fish was good, with 100% of the tags operating after 401 days. No tags were rejected from the fish during the observation period.
