According to the official sources (National Agency of Fisheries and Aquaculture) gobies in the industrial fish catches take second place only after the sprat. In fact these catches are much higher, because the registered in the NAFA landings are less than 10% (unofficial data). This is the first in-depth survey on the gobies in Bulgaria, aimed to give information about the species composition in angling and commercial catches. It covered most of the Bulgarian Black Sea coastline for the period 2009-2012. The study sites, equipment and techniques were chosen to be as close as possible to these of the local fishermen, observations on the local markets and interviews with fishermen were also carried out. 8 of the 24 native to Bulgaria goby species were presented in the sampling. The largest percentage has taken the round goby (Neogobius melanostomus), followed by the black goby (Gobius niger), the giant goby (Gobius cobitis) and the mushroom goby (Neogobius eurycephalus); smaller part was taken by the knout goby (Mesogobius batrachocephalus). The smaller quantities were established for the grass goby (Zosterisessor ophiocephalus), broad-headed (Pinchuk’s) goby (Neogobius cephalargoides) and rock goby (Gobius paganellus). Also there are clear indications for overfishing of this fish resource.
