Growth and mortality of European glass eel Anguilla anguilla marked with oxytetracycline and alizarin red

Abstract

The growth and mortality of European glass eel Anguilla anguilla 192 days after marking with oxytetracycline and alizarin red S were not significantly different between the two treatments and not different to the unmarked A. anguilla.

Short-term responses of glass eels transported from UK to small Belgian streams

“…Tributaries, lakes and ponds with low or no natural immigration have been stocked using glass eels and elvers caught in river estuaries (Walter, 1910;Mu¨ller, 1975;Klein-Breteler et al, 1990;Simon et al, 2009) and farm eels (Wickstro¨m et al, 1996;Pedersen, 1998Pedersen, , 2000Pedersen, , 2009Simon et al, 2013). The annual length increases and survival rates in the stocked eels vary strongly between the stocking environments, the stocking materials (farm and glass eels), the stages (smaller and larger eels) and times after stocking (Bisgaard and Pedersen, 1991;Pedersen, 1998;Lin et al, 2007;Simon et al, 2013;Simon and Do¨rner, 2014).…”

Evaluation of marking efficiency of different alizarin red S concentrations on body fish structures in <i>Oreochromis niloticus</i> (Perciformes: Cichlidae) juveniles

“…according to Simon et al (2009) the growth and mortality of European glass eel Anguilla anguilla 192 days after marking with oxytetracycline and alizarin red S were not significantly different between the two treatments and not different to the unmarked A. anguilla. The study provided evidence that both marking methods (OTC and ARS) fulfill the capturerecapture assumption of no effect on growth and survival within the glass-eel A. anguilla stage.…”

“…In this study ARS showed eight months permanence. According to Simon et al (2009) fish marks with ARS and oxytetracycline were clearly visible after a period of two years in specimens of Anguilla anguilla. The visibility of the marks eight months after marking definitely indicates that the chosen methods allocate for recognition of released individuals.…”

“…They found that the osmotic induction-marked fish possessed more intense marks and that these marks remained visible nine months after treatment. Mark production using ARS it is consider as nontoxic for several species (Lucas et al 2008, Simon et al 2009) and human consumption; also is acceptable to the public for commercial use (Rothlisberg & Preston 1992).…”

Marking of otoliths, age validation and growth of Argyrosomus regius juveniles (Sciaenidae)

“…Batch marking by immersion in chemicals that fluoresce under UV light and bind to the growing edge of the otolith, allows the marking of large numbers of juveniles and young fish. Once an adequate treatment has been defined (Wright et al, 2002;Taylor et al, 2005), it generally leads to good mark retention minimum mortality, and is less-time consuming in comparison with other marking methods (Simon et al, 2009). Otolith marks have been produced in juvenile fishes using chemicals such as oxytetracycline hydrochloride (OTC) (McFarlane and Beamish, 1987), alizarin complexone (ALC) (Reichert et al, 2000), alizarine red (ALR) (Simon et al, 2009) and calcein blue (Bumguardner and King, 1996), among others.…”
