Resumen

Esta investigación informa el LWR de peces ornamentales de lagos de llanuras aluviales de la cuenca del río Solimões. Los peces fueron capturados en la isla de Paciência (una isla fluvial) en dos lagos Sacambú y Cacau utilizando cerco 7 m × 4 m y tamaño de malla = 3 mm, una vez durante la inundación en junio de 2017 y seco en enero 2018. Las muestras capturadas se anestesiaron con eugenol 15 mg · L–1, se fijaron formalina al 10% y se almacenaron etanol al 70% después de 10 días. Este estudio proporciona los parámetros LWR para las especies Anablepsoides micropus, Anchoviella jamesi, Cichlasoma amazonarum, Heros efasciatus, Ctenobrycon hauxwellianus, Copella nattereri y Hemigrammus levis. El parámetro a varió de 0.0092 a 0.0229, b varió de 2.78 a 3.50 y el R2 varió de 0.985 a 0.998. Los resultados representan nueva información sobre peces ornamentales de lagos de llanuras aluviales, con nuevos LWR para cinco especies que no están presentes en el conjunto de datos FishBase y probablemente son nuevos para la ciencia. Este estudio es preliminar y queda mucho trabajo por hacer, especialmente en las áreas de la llanura aluvial del río Solimões y con nuestra investigación esperamos alentar nuevos estudios en la región.
