Distribution<br />
Europe: The Prespa Lakes. During most of the its life span it stays in the open waters. Usually it forms<br />
large shoals which move under the water surface. During the winter period large groups of individuals are<br />
sheltered at certain places protected from the wind <strong>and</strong> waves.<br />

Përhapja<br />
Evropë: Liqenet e Prespës. Gjatë pothuajse tërë kohës së jetës së vet ajo qëndron në ujërat e hapur. Zakonisht<br />
krijon tufa të mëdha në fund të ujit të cilat lëvizin nën sipërfaqen e ujit. Peshku zakonisht formon tufa të<br />
mëdha nën sipërfaqen e ujit. Gjatë periudhës së dimrit grupe të mëdha të tyre gjejnë strehim nga erërat dhe<br />
valët në vende të caktuara.<br />
Κατανομή<br />
Ευρώπη: Λίμνες Πρεσπών. Κατά το μεγαλύτερο διάστημα της ζωής του βρίσκεται στα ανοικτά νερά. Συνήθως<br />
δημιουργεί μεγάλα κοπάδια τα οποία κινούνται κάτω από την επιφάνεια του νερού. Κατά την χειμερινή<br />
περίοδο μεγάλες ομάδες ψαριών βρίσκουν καταφύγιο σε συγκεκριμένα μέρη που προστατεύονται από τον<br />
αέρα και τα κύματα.<br />
Biology<br />
The bleak migrates to spawning sites in<br />
tributaries <strong>and</strong> along the lake shore (on<br />
pebbles <strong>and</strong> gravel in the surf zone)<br />
during the night in small <strong>and</strong> large shoals,<br />
where there are only one or two females.<br />
All the other are males. The number of<br />
eggs is varied <strong>and</strong> depends upon the age<br />
<strong>and</strong> weight of the individuals but it can<br />
reach 10 000. Bleak spawn from May till<br />
August.<br />
<strong>Fish</strong>ing significance<br />
High significance for commercial <strong>and</strong><br />
recreational fishing.<br />
Threats<br />
There is a potential threat to the species<br />
from water abstraction, drought, pollution<br />
<strong>and</strong> introduced species which could<br />
impact the whole lake. Bleak is the main<br />
prey for breeding Dalmatian pelicans<br />
(Pelecanus crispus) <strong>and</strong> cormorant<br />
(Phalacrocorax carbo) <strong>and</strong> other fish<br />
eating birds.<br />
Conservation actions<br />
Strictly limited fishing quotas.<br />
