Detection of zooplankton predator-prey interactions in Alboran Sea by combining acoustic backscatter data and different sampling systems
MetadatosMostrar o rexistro completo do ítem
Multifrequency acoustic technology was used to detect the summer epipelagic scattering layer (SESL) associated with a heterogenic zooplankton community in Alboran Sea. Simultaneously, identification hauls by means of two different plankton net (bongo 40 equipped with 250 and 333 μm mesh and bongo 90 equipped with 500 and 2000 μm mesh) were performed to obtain taxonomical and quantitative characteristics of the zooplankton community. Collected data revealed a strong correlation between the abundance of small crustacean (prey) captured by the 250 μm mesh with the abundance of chaetognaths, siphonophores and fish larvae (predators) captured by 500 μm mesh.
