Population structure, condition, and reproduction characteristics of native monkey goby, Neogobius fluviatilis (Actinopterygii: Perciformes Gobiidae), in the Bulgarian Danube

Original language description

Monkey goby is one of many Neogobius species that have invaded European waters in recent decades. Little interest has been paid to this species up till now, probably due to its lower rate of invasiveness compared to some other goby species, e.g., round goby. As with any non-native species, however, it represents a potential danger for native fauna. The aim of this study is to fill in the missing data concerning monkey goby biology and population structure in its native area of distribution, thereby providing a baseline for future comparative studies in non-native distribution areas. Samples of monkey gobies, Neogobius fluviatilis (Pallas, 1814), were obtained seasonally from the lower, Bulgarian stretch of the Danube River during 2006. The fish collected were sexed, measured, and weighed. After that the gonads were removed and weighed. These data were used to calculate sex ratio, length-frequency distribution, condition coefficient, and gonadosomatic index. Dissected ovaries were used
