Visible Implant Elastomer Tags (visible + implant_elastomer_tag)
Selected AbstractsEvaluation of marking European silver eels with visible implant elastomer tags and alcian blueJOURNAL OF FISH BIOLOGY, Issue 1 2007J. Simon After 183 days, the retention of the visible implant elastomer marks implanted on the belly and along the basis of the ventral fin margin of the European silver eel Anguilla anguilla was 100%. The retention of the alcian blue spots on the belly was 84% after 1 day, but decreased to 68% by the end of the experiment (after 183 days). Marking-induced mortality was 0% for both marking types over the complete trial period.

Summers Retention of both rigid and new soft standard size visible implant (VI) tags in brown trout Salmo trutta after 6 months varied between 42 and 97% for different batches, with no evidence of increased retention of the new type of tag. The 6 month retention of visible implant elastomer tags (VIE) also varied but with a mean of 96%. The VIE retention gradually declined with time up to 42 months. [source] Development and testing of a pedigree-marking system using visible implant elastomer tags for selective improvement in Morone breeding programmesAQUACULTURE RESEARCH, Issue 8 2010Sidney Adam Fuller Abstract The development and testing of a visible implant elastomer pedigree-marking system was evaluated in sunshine bass, Morone chrysops×Morone saxatilis, and white bass, M. chrysops (Rafinesque). These tags were tested in sunshine bass fingerlings at one of four subdermal body locations (posterior to the eye, dorsal fin musculature, caudal fin musculature or anal fin musculature). Tag visibility decreased with increased sunshine bass growth (63% after 56 days). Visibility differed among body locations, with the caudal and anal tagging locations having lower visibility. White bass fingerlings representing eight genetic groups were then tagged at one of two body locations (left or right subdermal along the dorsal musculature) using one of four fluorescent colours and reared for 42 days in a common garden growth trial. Tag visibility in white bass was 99.5% at 14 days, 98.2% at 28 days and 94.9% at 42 days after tagging. There was a significant change in weight among the eight genetic groups of white bass fingerlings after 42 days (P=0.03). Testing of this pedigree tagging system successfully identified phenotypically different groups of white bass fingerlings. [source] Evaluation of visible implant elastomer tags for tagging juvenile gilthead seabream (Sparus auratus L.); effects on growth, mortality, handling time and tag lossAQUACULTURE RESEARCH, Issue 8 2005Nicolás Astorga Abstract The use of the fluorescent visible implant elastomer (VIE) tagging system in juvenile gilthead seabream, Sparus auratus L., between 7 and 18 g was examined. Four different colours (red, green, orange and yellow), three body positions (dorsal, lateral and caudal) and two orientations (horizontal and vertical) were tested. The mean tag application time for each fish was 15.7±0.32 s. There was no mortality associated with the method of tagging. The most visible tag colour was red. Injection orientation had a significant effect on length, width, fragmentation and fluorescent intensity of the tag. Horizontal tagging is recommended because of high fluorescent intensity, low fragmentation and for double tagging. There were no differences in growth between untagged controls and the VIE-tagged fish. [source] | ||||||||||
