The feasibility of tagging and recovering herring with external body tags - a pilot study / by D.E. Hay, C.W. Haegele, and D.C. Miller. : Fs97-4/1505E-PDF

"The feasibility of tagging large numbers of herring and recovering tags in fish processing plants was examined in this study. Twelve hundred herring were tagged and released into ponds containing a total of about 350,000 herring. Four days later the fish were removed and trucked to a processing plant. Of the three colours used, orange tags had the highest returns (33%), followed by yellow (23%) and pink (22%). During the 2 days of processing, the speed of operations increased steadily and the recovery rate declined. Some plant workers were more helpful than others and differences in shifts were noted. The rate of recovery in this operation (27%) was judged to be low compared to that of roe processing which requires much more handling of individual fish"--Abstract, page iii.
