CONTRIBUTIONS TO THE KNOWLEDGE OF THE BIOLOGICAL CHARACTERISTICS OF MAIN MARKETABLE FISH SPECIES FROM THE BLACK SEA ROMANIAN AREA, BETWEEN 2005-2009

The study presents the results of research undertaken in the Romanian Black Sea coastal fishery, from 2000 to 2009. The aim of the paper was mainly to track the biological features of the main fish species of commercial interest, populating the Romanian seaside i-0n and hydroclimatic conditions specific to the period under analysis. The paper refers to the structure of different species taken into consideration different variables such as: length and mass classes, age, sex ratio, degree of maturation, establishing the relation length/mass. The species under study were the following: Sprattus sprattus (sprat), Trachurus mediterraneus ponticus (horse mackerel), Engraulis encrasicolus (anchovy), Merlangius merlangus euxinus (whiting), Psetta maxima maeotica (turbot), Neogobius melanostomus (black spotted goby) and Mullus barbatus ponticus (red mullet).
