Nocturnal investigation of Planktonic ostracods in the South Adriatic sea

Night-time distribution of planktonic ostracods was investigated down to 300 m depth in the open South Adriatic Sea in spring 2009. Among twelve recorded species, Porroecia spinirostris dominated in the upper epipelagic layer, Archiconchoecia striata in the lower epipelagic and Proceroecia macroprocera in the upper mesopelagic zone. The highest ostracod average abundance of 519.1 ± 251.84 ind. 100 m-3 was found in the lower epipelagic layer. With the exception of P. spinirostris, recorded species showed higher nocturnal abundances below 100 m depths, with no evidence of near- surface upward migrations during night.
