1997 Pavia River Native Fish Monitoring <br />A total of 14 flannelmouth suckers were scanned for PIT tags. Six of these <br />scanned fish were recaptures (Table 3). Information regarding initial mark of five of the six fish <br />indicates that flannelmouth sucker growth, depending on size, ranged from 1.7 - 6.8 mm/30 days <br />and 21.3 - 83.9 mm/year (Table 4). One adult flannelmouth sucker (PIT tag # 1F77785B17) lost <br />weight and length since being marked. This fish may have been a female that lost length due to <br />spawning (e.g, frayed fins) and weight to expression of gametes. Eight flannelmouth suckers <br />(>150 mm TL) were implanted with PIT tags (Table 5). <br />Table 4.
