Fish

 

 

Only 8 fish species are established on the territory of the protected area and most of them are without economic significance.

The most widely spread is the eastern mosquitofish (Gambusia holbrooki). This South American species has been introduced in Bulgaria for the purposes of fighting malaria, as the basic food of the eastern mosquitofish are the larvae of mosquitoes, which could transmit the disease.

 

The Caucasian dwarf goby (Knipowitschia caucasica)  and the three-spined stickleback (Gasterosteus aculeatus), which are species, included in the Red Data Book of Bulgaria, are widespread in the protected area.  

There are about 42 fish species in the surroundings of Poda Protected Site.
