Jablaničko lake (bosanski. Jablaničko jezero) is a
large artificially formed lake on the Neretva river, right below
Konjic where the
Neretva briefly expanding into a wide valley. River provided lot of
fertile, agricultural land there, before lake flooded most of it.
The lake was created in 1953 after construction of large
gravitational hydroelectric dam near Jablanica in
and Herzegovina. The lake has an irregular elongated shape. Its
width varies along its length. The lake is a popular vacation
destination in Bosnia
and Herzegovina. Swimming, boating and especially fishing are
popular activities on the lake. Many weekend cottages hae been
built along the shores of the lake. There are 13 types of fish in
the lake's ecosystem.
But this, in fact, is not an advantage as lake suffered from poor management of water and fisheries. Without any scientific and management plans or research, local fisheries and angling management introduced, alien, non-indigenous or non-native species, either deliberately or accidentally, which done more harm and damage than good. As the Neretva has many endemic and fragile species of fish that are near extinction, introductions of this invasive species, Pike Perch (Stizostedion lucioperca L.), completely destroying native endemic and highly endangered fish like Strugač (Leuciscus svallize svallize Heck. et Kn.) or (Squalius svallize) and Glavatica (Salmo marmoratus) (also known as Gonjavac).
