26.3 Results and Discussion
The investigations performed allowed us to draw-up maps comprising the distribution of the five marine fish species whose presence was confirmed within ROSCI
0066, in both biogeographic areas covered (Pontic/PON and Black Sea/MBLS)
(Mihailescu et al. 2015).
Alosa immaculata
Pontic shad was the species permanently recorded in catches made during the
scientific fishing surveys. The largest number of shads were caught in the Sulina
area (more than 30%), followed by Sachalin (around 18%), Periboina (around
18%), Zatoane, Perisor and Sf. Gheorghe (around 8% each).
This species was also reported in the other sectors of ROSCI 0066, but in small
numbers Chituc (around 2%), Gura Portitei (around 2%), Periteasca (around 1%)
and Vadu (around 1%) (Figs. 26.17 and 26.18).
Applying the methodology for reporting under Article 17 of the Habitats Directive, it resulted that the overall conservation status for the species A. immaculata
(Pontic shad) in the marine zone of the Danube Delta (ROSCI 0066) is favourable
(FV) (Table 26.2), status which applies for the entire Romanian coastal area.
