Preliminary Data on the Studies of Alosa immaculate in Romanian marine waters

Abstract

Danube shad is a fish with high economic and socio-cultural value for the human communities established in the Danubian-Pontic space. In Romania, shad fishery has a market value of about 1.5 million euro, with average annual catches of 200-500 tonnes. Biological material was collected during research surveys organized along the Black Sea coast, in 2012-2013, in spring season (March, April), summer (June, July) and autumn (September). Experimental fishing was done with fishing gillnets. Demographic structure of Alosa immaculata consists of generations of 2-5 years, dominated by generations of 3 to 4 years. The aim of this paper is to provide recent data regarding Alosa immaculata population along the Black Sea Coast considering that its biology is less known.
