Currently, in the continental and marine waters of the Earth, there are over 33,400 species of fish. Over time, naturalists, and specialists in ichthyology have proposed several variants of systematic classification of fish. Thanks to new methods and advanced scientific research equipment, 300-500 new species are discovered every year. This explains the fact that in just 20 years (1998-2017), 7,436 species were described. In 2004, the scientific organization Integrated Taxonomic Information System published ITIS Report, in which a complete taxonomic hierarchy of the genus Alosa is presented. Alosa immaculata (Pontic shad), is an important fish species in the ecological system of the Danube-Delta-Black Sea, with a significant economic value due to the high catches and to the nutritional qualities of meat. The knowledge of the essential elements regarding the biology and the exploitation of the species contributes to ensuring the necessary information for the conservation of the species and the management of the stocks. The current level of knowledge on the biology of the Pontic shad is known from the researches of the Romanian and Russian specialists from the years 1960-1970, but in the last 30 years, numerous changes have occurred in the environmental and exploitation conditions of the species. In this context, the aim of this paper is to present as updated information as possible regarding the biology and exploitation of the Pontic shad, under the new environmental conditions, to meet the current objective of species conservation in the requirements of the sustainable exploitation of the stocks.
