“…High feasibility and efficiency of CWTs in marking various fish species have been illustrated under laboratory and field conditions, including little influence on fish growth, low tagging-induced mortality, and high tag retention (Heidinger and Cook 1988;Hale and Gray 1998;Brennan et al 2005;Vander Haegen et al 2005). Wire tagging is therefore widely used in fishery management to assess fish growth and mortality (Hervas et al 2010) (Adlerstein et al 2007a;Adlerstein et al 2007b;Flostrand et al 2009), habitat selection (Able et al 2006), population abundance (Parken et al 2008), and harvest (Bernard and Clark 1996).…”

Redtail culter Culter mongolicus, a threatened piscivorous fish species in China's inland waters, has exhibited serious population decline. As part of a stock enhancement research project in shallow lakes of the Yangtze River basin, China, we evaluated the performance of coded wire tags (CWTs) for marking juvenile redtail culter. Through a short‐term indoor experiment, we marked hatchery‐reared juveniles from three size groups (mean ± SE, small: 46.85 ± 0.67 mm, intermediate: 53.76 ± 0.62 mm, large: 63.42 ± 1.05 mm) in the dorsal muscle with CWTs and tested whether marking effects on tag retention and mortality were size‐specific. Tag retention was more than 98% in all the three size groups and appeared to be unaffected by fish size. Tag losses were found only within 3 d of marking. Tagging‐induced mortality of small marked juveniles (58%) was significantly higher than those of intermediate (5%) and large (1%) marked juveniles and was also significantly higher than small unmarked ones (17%). The relationship of marked mortality and total length was quantitatively described by an exponential decay model. Mortality in small marked juveniles occurred mainly within 24 h after marking, which accounted for 71% of the mortality in this marked size. In order to avoid high posttagging mortality and biases in stocking assessment programs, we suggest it is worth the extra fish‐culture costs to use juveniles of at least 57 mm (which displayed 90% survival in our experiment) for stocking assessment programs that utilize CWTs for a handling‐sensitive species like redtail culter.

“…The tag loss varied from 0% to 13% (I. Kolari, unpublished data). Tag losses of less than 10% are considered acceptable for most research needs (Heidinger & Cook 1988). In the light of the high tag loss in lake stocking of Arctic charr, an experiment was organised to: (i) assess if the long‐term tag loss was size dependent; and (ii) test some moulds made by Northwest Marine Technology Inc., Shaw Island, WA, USA (NMT) for other salmonids to determine suitable moulds for Arctic charr tagging.…”

A hatchery experiment was organised to find out if the high loss rate of coded wire tags, noticed in connection with an Arctic charr Salvelinus alpinus (L.) restocking programme, was size-dependent and also to test head moulds for future taggings. Six moulds made by Northwest Marine Technology Inc. and five moulds made at the Finnish Game and Fisheries Research Institute were used. A total of 100 charr were tagged with standardlength coded wire tags using each mould. One-summer old charr at tagging were held for 534 days and twosummer old charr for 320 days. The tag loss rate varied between 0% and 54% and was negatively related to the size of the charr at tagging. The high loss rate was connected with the poor alignment of some moulds, such that a large proportion of the tags were located in the nasal cavity instead of the nasal cartilage. Testing of the moulds and careful grading of the fish for tagging is emphasised, especially if Arctic charr smaller than 20 g in weight are to be tagged.

RÉSUMÉIl est souvent nécessaire de marquer les poissons pour contrôler l'efficacité des opérations d'alevinage ou étudier la dynamique des populations en milieu naturel. L'article décrit des adaptations de deux techniques de marquage d'alevins d'Ombre commun (Thymallus thymallus L.) de 6-8 cm : (1) l'ablation par cautérisation de la nageoire adipeuse et (2) l'injection de micromarques magnétiques dans le cartilage nasal. Afin de mettre en évidence les effets à long terme de ces deux techniques de marquage, la survie et la croissance d'alevins marqués ont été comparées à celles d'alevins témoins non marqués élevés en bassins artificiels. Les taux observés de rétention ou de persistance des marques étaient très élevés (> 99 %). Les taux de survie et de croissance des alevins marqués, élevés séparément ou non, n'étaient pas significativement inférieurs à ceux des alevins témoins. Les deux méthodes sont donc bien adaptées au marquage de groupes de juvéniles d'Ombre commun.Mots-clés : micromarques magnétiques, cautérisation de la nageoire adipeuse, survie, croissance, ombre commun. FIRST EVALUATION OF TAGGING TECHNIQUES ON YOUNG EUROPEAN GRAYLING (Thymallus thymallus L.) BY CAUTERISATION OF THE ADIPOSE FIN OR BY INJECTION OF CODED WIRE TAGS ABSTRACTIt is often necessary to tag fish in order to control the efficiency of stocking or to investigate population dynamics in the wild. The paper deals with adaptations of two methods of tagging young European grayling (Thymallus thymallus L.) of 6-8 cm long: Bull. Fr. Pêche Piscic. (2003) (1) ablation by cauterisation of the adipose fin and (2) injection of coded wire tags into the nasal cartilage. In order to investigate the long-term effects of each tagging techniques, survival and growth of young tagged fish were compared to those of untagged fish. Rearing took place in artificial tanks and ponds. Observed rates of tag retention or tag persistence were very high (> 99%). Both survival and growth rates of tagged and untagged groups of fish, reared apart or not, did not differ significantly. Consequently, both methods appear to be suitable for tagging groups of young grayling.
