Size, weight, and diet of the invasive lionfish Pterois volitans (Linnaeus, 1758) on the southern coast of Veracruz, Gulf of Mexico

The invasion of the Indo-Pacific lionfish Pterois volitans has produced detrimental impacts on the regional biodiversity and fisheries of invaded ranges. To understand the effect this lionfish may have on the native fish communities, it is necessary to understand its feeding habits. The objectives o...

To understand the effect this lionfish may have on the native fish communities, it is necessary to understand its feeding habits. The objectives of this study were to report new distribution records of P. volitans along the southern coast of Veracruz (México), to document the feeding habits of the collected specimens, and to determine if there was a relationship between the diet, size, and weight of those specimens. The density of P. volitans in our study area was low. Diet composition for this species consisted of bony fishes (95.40%), crustaceans (4.20%), and mollusks (0.36%). Lionfish size and weight were positively correlated. We did not find statistical differences between the diet and the size/weight groupings; however, the smaller specimens seemingly had a more varied diet than the larger specimens.   La invasión del pez león del Indo-Pacífico Pterois volitans ha producido impactos perjudiciales sobre la biodiversidad regional y las pesquerías de zonas invadidas. Para comprender el efecto que puede tener el pez león en las comunidades nativas, es necesario conocer sus hábitos alimenticios. Los objetivos de este estudio fueron documentar nuevos registros de distribución de P. volitans a lo largo de la costa sur de Veracruz (México), documentar los hábitos alimenticios de los especímenes recolectados y determinar si existía una relación entre la dieta, la talla y el peso de estos especímenes. La densidad de P. volitans en nuestra área de estudio fue baja. La composición de la dieta de esta especie consistió en peces óseos (95.40%), crustáceos (4.20%) y moluscos (0.36%). La talla y el peso del pez león estuvieron positivamente correlacionados. No encontramos diferencias estadísticas entre la dieta y los grupos de talla/peso; sin embargo, los especímenes de menor talla, aparentemente, tuvieron una dieta más variada que los especímenes de mayor talla.   Iniversidad Autónoma de Baja California 2020-03-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada application/pdf text/xml text/xml https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3012 10.7773/cm.v46i1.3012 Ciencias Marinas; Vol. 46 No. 1 (2020); 57–64 Ciencias Marinas; Vol. 46 Núm. 1 (2020); 57–64 2395-9053 0185-3880 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3012/420420492 https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3012/420420947 https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3012/420420651 Copyright (c) 2020 Ciencias Marinas https://creativecommons.org/licenses/by/4.0
