The nonindigenous fish Perccottus glenii in the Tisza River drainage, Eastern Slovakia – I. part: history of invasion, habitat associations and genetic characteristics (results up to the year 2006)

Original language description

The Amur sleeper Perccottus glenii was first discovered in the Tisza River drainage (Danube River basin) in eastern Slovakia in 1998. Here we update information on the geographic dispersal of the Tisza River population and provide details on its genetic characteristics and habitat associations. The original site of introduction of P. glenii into the Tisza drainage was the Transcarpathian region of Ukraine. In less than ten years, P. glenii expanded its range (presumably with the aid of periodic floods) resulting in a broad distribution encompassing about one thousand kilometers of the Tisza River, from its upper tributary streams (e.g., Latorica and Bodrog rivers) downstream to the Tisza mouth and into the main Danube River. Karyological and genetic analyses were conducted using specimens captured at Svätá Mária (eastern Slovakia). In contrast to previous reports on P. glenii, the karyotype structure (2n = 44) of the Tisza River population contained one pair of submetacentric chromosomes, 16 pairs of subtelocentric, and 5 pairs of acrocentric chromosomes, indicating a possible link to introduced P. glenii from the Moscow area. Of 20 loci examined, 8 were polymorphic. More than two alleles were found in sAAT-1* (180,100,120) and SOD* (050,100,150,175,200). The statistical values for the loci examined indicate a very low level of heterozygosity. Analysis of mtDNA gene cytochrome b (546 base pairs) indicated the presence of two haplotypes differing in 5 nucleotides. Presence of two haplotypes was confirmed by analysis of the SOD enzyme. In the study area, P. glenii are abundant and closely associated with vegetated, lentic habitats. There is evidence that P. glenii is eliminating or displacing certain native and non-native fish species (e.g., Umbra krameri, Leucaspius delineatus, Carassius carassius).
