Abstract
Abstract – The otolith composition of age 0+ Allis shad (Alosa alosa) captured in two rivers in the Gironde system in south‐west France, the Dordogne and the Garonne, was analysed to establish the natal origin of the fish. Inductively coupled plasma mass spectrometry analyses were used to take measurements of 15 isotopes, among which Co, Fe, Sr and Rb were the most important elements in the discrimination process. It was possible to reclassify each sampled fish into its natal river basin (Garonne or Dordogne) with a high degree of accuracy. Linear discriminant analysis correctly reclassified 91.1% of the Garonne samples and 87.8% of the Dordogne samples (mean success in reclassification in 20 runs ± 1 SD: 89.21 ± 8.6%). Artificial neural networks correctly reclassified 90.1% of the Garonne samples and 81.2% of the Dordogne samples (mean success in reclassification after 1000 training cycles ±1 SD: 85.6 ± 9.1%). Using these tools the present results show that it is possible to assign a natal origin to juvenile shad that hatched in the Dordogne–Garonne basin based on the trace elements in the otolith.

El Plasma Acoplado por Inducción con Espectrómetro de Masas (ICPMS) permitió la cuantificación de 15 isótopos en los otolitos de los cuales Co, Fe, Sr y Rb fueron los más determinantes en la discriminación. 2. Los individuos capturados fueron asignados a cada uno de los dos ríos utilizando el análisis discriminante lineal con tasas de correcta reclasificación del 91.1% para los individuos de Garonne y del 87.8% para los individuos de Dordogne (con una media de clasificaciones correctas ± desviación estándar de: 89.21% ± 8.6%). 3. Utilizando Redes Artificiales de Neuronas, las tasas de clasificación correcta fueron similares a las del análisis disciminante lineal: 90.1% para los individuos de Garonne y 81.2% para los individuos de Dordogne (con una media de clasificaciones correctas ± desviación estándar de: 85.6% ± 9.1%). 4. Estos resultados muestran que es posible asignar el lugar de origen a los juveniles de sábalo de la cuenca de Dordogne‐Garonne analizando los elementos traza de sus otolitos.</abstract><subject lang="en"><genre>keywords</genre><topic>stock discrimination</topic><topic>trace elements</topic><topic>inductively coupled plasma mass spectrometry</topic><topic>Aveyron</topic></subject><relatedItem type="host"><titleInfo><title>Ecology of Freshwater Fish</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0906-6691</identifier><identifier type="eISSN">1600-0633</identifier><identifier type="DOI">10.1111/(ISSN)1600-0633</identifier><identifier type="PublisherID">EFF</identifier><part><date>2005</date><detail type="volume"><caption>vol.</caption><number>14</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>185</start><end>190</end><total>6</total></extent></part></relatedItem><identifier type="istex">99F2EF8A7F9820D963EB585B7CD13F340452FDFC</identifier><identifier type="DOI">10.1111/j.1600-0633.2005.00090.x</identifier><identifier type="ArticleID">EFF090</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Munksgaard International Publishers</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
