Seasonal distribution of oikopleura (Larvacea) in the lagoon of venice

Abstract

The appendicularian population in the ebb and flow of the lagoon of Venice was studied for two years. Only three species were found, Oikopleura dioica, O. longicauda and O. fusiformis, the former being the more abundant. The seasonal distribution of the species was correlated to the hydrological conditions of the upper Adriatic Sea. There was a dramatic decrease (about 802) in the biomass of these appendicularians inside the lagoon between flow and ebb tide. © 1990 Taylor & Francis Group, LLC.
