Radiotelemetry <br />The spatial and temporal movements ofdomestic-reared and wild sub-adult and adult <br />Colorado pikeminnow implanted with radio transmitters were monitored by tracking from boats, <br />vehicles, and by stationary, semi-permanent, land-based tracking stations. Radiotelemetry <br />provided data on the movement and fate of Colorado pikeminnow following release in the Upper <br />Colorado River, the duration of time they spent in particular reaches, and documented <br />entrainment into and movement in the Government Highline and GVIC Canal systems. <br />Surgical Procedures <br />Surgical protocol for implanting radio transmitters was established from procedures <br />initially developed for Colorado pikeminnow by Hart and Summerfelt (1975) and Miller et al. <br />(1983). <br />Telemetry Equipment <br />Transmitters. Either the LOTEK® model MCFT-7A (7-volt battery output; 29 grams air <br />weight) or MCFT-3FM (3-volt battery output; 10 grams air weight) digitally encoded transmitter <br />(148-152 Mhz) was implanted interperitoneally in sub-adult and adult Colorado pikeminnow. <br />These transmitters were no more than 2% of the fish's body weight. Each transmitter had a <br />unique identity code (e.g., Code 78) which was the fish's specific transmitter signature. Each <br />transmitter had a 40-cm external trailing antenna, that consisted of aplastic-coated metal cable, <br />which extended outside the fish. This required a slight modification in surgical technique (Ross <br />1982; Burdick 2000; see Appendix C for a detailed explanation of surgical and radio-tag <br />implantation techniques). The MCFT-7A transmitter was 16 mm in diameter, 83 mm long, and <br />had a guaranteed life expectancy of 260 days. This transmitter was implanted in three of the wild <br />Colorado pdceminnow in 2000 and all 19 of the wild fish in 2001. The MCFT-3FM transmitter <br />was 11 mm in diameter, 59 mm long, and had a life expectancy of about 560 days. <br />The lighter and smaller radio transmitter, the MCFT-3FM module, was implanted in two <br />of the smaller wild Colorado p~keminnow in 2000 and all five of the 1991 domestic-reared year- <br />class Colorado p~lceminnow in 2000. The MCFT-7A transmitter was too large to implant in <br />Colorado pdceminnow that were less than 500 mm. Thus, the MCFT-7A transmitter was used in <br />Colorado pdceminnow that were 500 mm and larger; the MCFT-3FM transmitter was used in <br />9 <br />
