Volunteer Species of Plants that Can Become Dangerous to Pisciculture

The purpose of this paper was to identify the existing species of plants around as well as inside the Aghires lakes and to determine their influence on the development of fish populations. The methods used refer to direct observation as well as identification of different associations. Following surface mining activity in the village of Aghires, Cluj nine artificial lakes were formed throughout the years. These lakes are surrounded by sterile hills that start to be covered by vegetation. The palustrine vegetation depends entirely on the water pH. From the vegetation point of view two major vegetation groups can be observed: aquatic or palustrine, among which there are no obvious limits.
