Comparative feeding behaviour of Penaeus kerathurus (Forskål, 1775) (Crustacea, Penaeidae) and Palaemon Serratus (Pennant, 1777) (Crustacea, Palaemonidae) during larval development

Comparative feeding behaviour of Penaeus kerathurus (Forskål, 1775) (Crustacea, Penaeidae) and Palaemon Serratus (Pennant, 1777) (Crustacea, Palaemonidae) during larval development

Aspects of larval feeding of two autochthonous species of shrimp, Penaeus kerathurus (Forskål, 1775) and Palaemon serratus (Pennant, 1777), were studied. For P. kerathurus, feeding rates on Chlorella sp. and Isochrysis galbana Parke were determined at 3 different concentrations, during the protozoea...

For P. kerathurus, feeding rates on Chlorella sp. and Isochrysis galbana Parke were determined at 3 different concentrations, during the protozoeal stage, and on Artemia franciscana Kellog at 4 different densities, during the mysis stage. The selectivity between Brachionus plicatilis Müller and Artemia franciscana nauplii was tested experimentally and the Ivlev selectivity index was calculated at the mysis stage. For Palaemon serratus Zoea III, V and VII, feeding rates on newly hatched A. franciscana nauplii, on metanauplii enriched during 24 hours in Protein Selco– and on starved metanauplii were determined. The Ivlev selectivity index was also calculated. The results revealed that Penaeus kerathurus and Palaemon serratus larvae have a negative selectivity for B. plicatilis. It is also suggested that the optimal density of A. franciscana for the mysis stage of P. kerathurus is around 10 nauplii mL–1. Finally, it was shown that the use of enrichment products leading to a very high lipid content of the prey may reduce their consumption rate. Se estudiaron aspectos de la alimentación de larvas de dos especies autóctonas de camarón, Penaeus kerathurus (Forskål, 1775) y Palaemon serratus (Pennant, 1777). Se determinaron las tasas de alimentación de Penaeus kerathurus con Chlorella sp. e Isochrysis galbana Parke, en tres concentraciones distintas, durante el estadio de protozoea, y con Artemia franciscana Kellog, en cuatro densidades diferentes, durante el estadio misis. También se probó experimentalmente la selectividad de P. kerathurus entre Brachionus plicatilis Müller y nauplios de Artemia franciscana y se calculó el índice de selectividad de Ivlev, durante el estadio misis. Para Palaemon serratus en los estadios Zoea III, V y VII, se calcularon las tasas de alimentación con nauplios recién eclosionados de A. franciscana, con metanauplios enriquecidos con Protein Selco® durante 24 horas y con metanauplios sin alimentar. También se calculó el índice de selectividad de Ivlev. Los resultados revelaron que las larvas de Penaeus kerathurus y de Palaemon serratus tienen selectividad negativa hacia B. plicatilis. También se sugiere que la densidad óptima de A. franciscana para el estadio misis de P. kerathurus es alrededor de 10 nauplios mL–1. Finalmente, se demostró que el uso de productos de enriquecimiento que conducen a un contenido muy elevado de lípidos en las presas puede reducir la tasa de consumo.
