Piranha in the Romanian rivers
Invasive species of kidnapping fish, which harm the domestic fauna and flora, were found in the waters of the Banat river basin, especially because of the voluntary human intervention, the specialists announced.
Cătălin Nagy, Resource Director within the Banat (ABAB) basin administration, reported, for Agerpres, that in the waters of Banat Montan were identified fish populations that are specific to the plain area. The assumption of the ones from Abab is that the fishermen who use the living bait randomly throw the Nada after fishing and thus multiply the « exotic » fish.
« We have confronted over time and we are still facing invasive fish species, which are mainly brought by ‘benevolent’, who throw their exotic fish in the water. These fish, even if they do not reproduce, can create local damages on the fauna and flora on the rivers or lakes. Small fish, which in the carp area are taken, for example, in the area of the trout. We find in the area of the plain.
The director of Abab explained that there is a fashion in the western countries to have the most exotic pets, from snakes and birds to donkeys or other people. As small, these pets are attractive, but after four to five months, the owner no longer knows how to get rid of them.
This is the case of aquarium or turtle fish; When the masters realize that they become expensive or they can no longer ensure their habitat, they release them in the water, by chance, creating great problems of the local fauna.
For his part, Cosmin Marius Ivaşcu, a lecturer at the Faculty of Chemistry, Biology, Geography of the Western University of Timisoara, told AGERPRES that today’s turtles have a great opponent in exotic turtles, bought from abroad or captured by parents for children, from the Danube Clisura, for example, which he then releases.
« The exotic turtles released in Bega and other wetlands, in the rivers are dangerous, being aggressive towards the native species, because they occupy the sunny places that are very important for our species. Parents must be warned, because some procure children to the little turtle, but it grows a lot, and they are very much, Large, they want to get rid of them and release them in Bega.
