Title: Effects of spatial distribution of light on prey ingestion of Atlantic halibut larvae
Abstract: The hypothesis that light distribution affects prey distribution and in turn influences prey ingestion was tested on Atlantic halibut larvae Hippoglossus hippoglossus . Low intensity concentrated light produced swarms of Artemia sp., but did not affect the distribution of Brachionus plicatilis . Low intensity diffused light, however, did not create swarms with either prey. As a consequence, halibut larvae ingested more Brachionus than Artemia in concentrated light, but not in diffused light. Due to differences in dry weight between Artemia and Brachionus , ingested biomass values were indistinguishable under the two experimental regimes.The term‘ population ingestion value’ is introduced as an expression for the ingestive capability of the population as a whole.
