Sažetak
Ecological, morphological-taxonomic and haematological features of pike perch (Sander lucioperca, Linnaeus 1758) as introduced species in reservoirs on the river Neretva in Bosnia and Herzegovina is presented in this paper. Field research has been carried out in the period from November 2009 to November 2010. The analysis of morphological-taxonomic paremeters has been carried out on 103 specimens, with 54 used for the analysis of haematological parameters. From an ecological standpoint, populations of pike perch from the „lakes“ on the river Neretva exhibit trends towards an increase in density. These populations include specimens of various age, and they show a high degree of adaptibility to the reservoir's ecosystems. Morphological features of specimens show the presence of several generations, which indicates that this species successfully spawns in the investigated ecosystems. The largest variation coefficient by season, within seven measured haematological parameters, have haematological indices MCV, MCH and MCHC.
