pairs length. The sequencing results indicated the fact that all the electrophoretic profiles
belonged to Saprolegnia ferax species.
At the fungal species from Saprolegniaceae family, collected from Ciurila fishery,
Cluj county, with 6 fishponds, in the fishponds 1,2,3,5 and 6 there can be observed 3
fragments of restricted DNA, the first one is about 400 bp, the second one has 200 bp, and
the third one has 130-150 bp. In the fishpond 4 there can be seen 4 DNA fragments, the first
one at 500 bp, the second one at 250 bp, the third one at 200 bp and the fouth one between
130-150 bp, which indicate the presence of a polymorphism, confirmed by sequencing as
belonging to Achlya bisexualis species.
At the fungal species from Saprolegniaceae family, collected from Chiochiş fishery,
BistriŃa-Năsăud county, with 5 fishponds, in the 1,2,3 and 5 fishponds, can be observed 3
fragments, with the following lengths: the first one between 400 bp and 500 bp, the second
fragment between 200 bp and 250 bp, and the third one between 150-200 bp. Those
electrophoretic profiles, correlated with the sequencing data and the GeneBank comparison,
indicated the presence of Saprolegnia ferax species. In the fishpond 4, the 3 fragments have
different lengths: the first fragment has 500 bp, the second one has about 250 bp and the
third one has 150-200 bp. After the fragment length analyses by electrophoresis, in the
fishpond 4 there is observed a different polymorphism compared to the other fungal DNA
samples, which indicates the presence of another species, confirmed as Achlya bisexualis.
At the fungal species from Saprolegniaceae family, collected from Daia fishery, Alba
county, with 5 fishponds, in the 1,2,3,4 fishponds there is remarked the presence of 3
restriction lanes, the first one having 400 bp, the second one 200 bp, and the third one 130-
150 bp, after the sequencing analyses being identified the aquatic fungal species named
Saprolegnia ferax. It can be seen a fragment length polymorphism at the fungal species
collected from fishpond 5, confirmed as belonging to Achlya bisexualis species. The first
fragment has 500 bp, the second one has about 200 bp. The third fragment is low visible.
At the fungal species from Saprolegniaceae family, collected from Iernut fishery,
Mureş county, with 5 fishponds, can be observed the same fragment lengths, in 1,2,3 and 5
fishponds. The first fragment has 400 bp, the second one had 200 bp, and the third one 130-
