Due to the high water level, Sector V will be relocated from Lake Salakovac to Lake Mostar.
Lake Mostar is the youngest reservoir lake on the Neretva river. This lake was made in 1987. Its maximum length is 10 km, its size is about 112 hectares, and maximum depth of 20 m.
Research has showed that this ecosystem has 8 types of fishes from 2 kinds; Salmonidae and Cyprinidae: Trout (Salmo trutta m. fario L), (Salmothymus obtusirostris oxyrhynchus Steind.), (Salmo marmoratus Cuv.), californian trout (Oncorhynchus mykiss Wal.). From Cyprinidae kind: (Leuciscus svallize svallize Heck. et Kn.), white chub (Leuciscus cephalus albus Bon.), carp (Cyprinus carpio L) and (Alburnus alburnus alborella de Filippi).
Analysing the qualitative essay of the ihtyofauna in artificial Mostarsko lake, it was concluded that in this ecosystem lives 3 spieces of authentic and 1 introducted salmonidae.
