A summary of information containing biological and ecological characteristics of introducers, their expected impact on the ecosystem, the receiving capacity of the reservoir to be colonized, the scheme of introductory works, biological and economic feasibility of the event.

Introduction is any relocation of individuals of a species to a body of water that has not been developed by them. Introduction is always the first step in the acclimatisation process, but it does not always end with the acclimatisation of the introducer.

Introduced species, or alien species in biology, are non-indigenous, non-native to a particular area, deliberately or accidentally introduced to a new location as a result of human activity. In contrast, a species that is native to an area is called a native species.

Introduced species can often significantly alter the existing ecosystem of a region and cause a significant reduction or even extinction of certain species of local flora and fauna: such introductions are often referred to as biological pollution.
