IDENTIFYING NAUPLIAL STAGESOF THE BLACK SEA COPEPODS OF CALANIDAE FAMILY IN FISH LARVAE GUTS
Nauplial stages of copepods are known to be the main food items for ﬁsh larvae. Their identiﬁcation in ﬁsh larvae guts is usually a diﬃcult task and a time-consuming procedure. Original approach to identiﬁcation of larvae and juvenile ﬁsh common food items - nauplial stages of the Black Sea copepods of family Calanidae - is proposed. This work is a continuation of the initiated studies on the developing a method for determining the juvenile copepod stages from ﬁsh larvae guts. On the example of nauplial stage III of Calanus euxinus Hulsemann, 1991, speciﬁc features that can be used in identifying nauplial stages of three species of the Black Sea copepods from ﬁsh larvae guts are shown.
