Stime di biomassa di Tubularia crocea (Agassiz, 1862) mediante monitoraggio fotografico in un' area a barriere artificiali nel nord Adriatico

In the framework of the project 'Intervento 72 - Campo Sperimentale in Mare' promoted by Regione Veneto (Italy) it was developed a low impact technique to monitor the benthic macrofauna in an artificial area in the North Adriatic Sea. During the first campaign in February 2004, photo of Tubularia crocea were taken. Some colony were collected to estimate the biomass; the goal is the evaluation of biomass through photographic technique.
