| What are the effects of salmonid stocking in lakes on
native fish populations and other fauna and flora? Part A: Effects
on native biota |
What is the aim
of the review?
To systematically collate and synthesise published and unpublished
evidence in order to address the following questions:
- “What are the effects of salmonid stocking
in lakes on native fish populations?”
- “What are the effects of salmonid stocking
in lakes on flora and fauna other than fish?”

At what stage is the review?
This review is now complete.
What is the rationale?
In Europe, North America and Australasia, lakes
are often stocked with salmonids to provide game fisheries. These
fisheries have a high socioeconomic value, but there is concern
regarding the ecological impact of stocking a species high in
the food chain, especially on other organisms of conservation
value.
The Countryside Council for Wales
identified the need for a systematic review
to evaluate the potential ecosystem effects of salmonid stocking
in lakes on native fish populations and other fauna and flora.
The specific question to be addressed was formulated through discussion
between the CEBC and 12 UK-based stakeholder organisations, including
the Association of Fisheries Trusts and the Scottish Environmental
Protection Agency (SEPA).
How were the results
obtained?
A number of electronic databases were searched for information
using a range of search terms. Internet searches were conducted
in order to retrieve any relevant grey literature. 42,150 references
were identified through the search strategy; 6 of these were accepted
into the final review having met all inclusion criteria.
