1. The genotyping of hydrobionts from the mock communities
The assessment of hydrobionts haplotypic variation by Leray fragment (313 bp) showed that seven sequences of H. octogrammus species contained 3 haplotypes in three variable sites. One of the haplotypes was present in five fish collected in Vityaz Bay. The other two were found in fish collected in Vostok Bay. The sequence matrix of the species P. dybowskii contains one variable site with two haplotypes without a clear association to localities. In shrimps P. latirostris we found two haplotypes located at one variable site. One of the haplotypes was found in a shrimp from Vityaz Bay, the second one is common to eight shrimps collected in Vostok Bay. The genotyping by the Folmer fragment (~650 bp) revealed similar results, with an exception that in H. octogrammus 5 haplotypes were found in 6 variable sites (Table 1).
