Resumo: The sea urchin Paracentrotus lividus (Lamarck, 1816) (Echinodermata: Echinoidea) is an important economic resource in Europe, but intense harvesting has led to the collapse of several natural populations. Echinoculture, associated with restocking and stock enhancement practices, is an alternative to this problem. In these procedures, reliable individual identification through tagging is a valuable source of information. However, very few studies address the effect of tagging methods on P. lividus and the tagging of marine invertebrates still presents several challenges: decreased growth, high mortality rates and low tag retention rates. Under laboratory conditions, the present study evaluated the effectiveness of three tagging methods (passive integrated transponders [PIT-tags], coded wire tags [CWTs] and calcein) on wild P. lividus for 60 days in terms of total wet weight, total weight gain (mg ind.−1 day−1), survival and tag retention. The final total wet weight was significantly higher in the untagged (control) group than in the PIT-tagged group. Survival rate was 100% for the PIT-tag, calcein and control groups, and 97% for the CWT group. Tag retention differed significantly according to the tagging method: 100% in the calcein group, 76.7% in the PIT-tag group and 38.0% in the CWT group.

La acuicultura de erizos de mar, asociada a las prácticas de repoblación y mejora del stock son alternativas a este problema. En estos procedimientos, una identificación individual fiable, a través de métodos de marcaje, representa una valiosa fuente de información. Sin embargo, muy pocos estudios abordan el efecto de los métodos de marcaje en P. lividus y el marcaje de invertebrados marinos aún presenta varios desafíos: disminución del crecimiento, altas tasas de mortalidad y bajas tasas de retención de las marcas. En condiciones de laboratorio, el presente estudio evaluó la eficacia de tres métodos de marcaje (passive integrated transponders - PIT-tags, coded wire tags – CWT y calceína) en P. lividus silvestre, durante 60 días, en términos de peso húmedo total, ganancia de peso (mg ind.−1 día−1), supervivencia y retención de etiquetas. El peso húmedo total final fue significativamente mayor en el grupo sin marcar (control), en comparación con los individuos marcados con PIT-tags. La tasa de supervivencia fue del 100% para los grupos PIT-tag, Calceína y Control, y del 97% para el grupo CWT. La retención de etiquetas fue significativamente diferente según el método de etiquetado: 100% en el grupo Calceína, 76,7% en el grupo PIT-tag y 38,0% en el grupo CWT.Editorial CSICIC-OnlineSantos, Pedro M.Quintella, Bernardo RuivoJacinto, DavidGomes, AnaSaldanha, CarolinaLourenço, SílviaLopes, Patrícia MegaCorreia, Maria JoãoMateus, DavidCruz, TeresaPombo, AnaCosta, José Lino2022-12-16T16:13:53Z20222022-12-15T19:21:26Z2022-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.8/7947engSantos P.M., Quintella B.R., Jacinto D., Gomes A., Saldanha C., Lourenço S., Lopes P.M., Correia M.J., Mateus D., Cruz T., Pombo A., Costa J.L. 2022.
