Revisiting oestrogenic effects in wild fish: assessing and comparing contemporary and historical impacts

The Environment Agency is undertaking an investigation to robustly investigate current levels of intersex and other oestrogenic effects in wild fish populations. This new study will seek to replicate the sampling approach and procedures from the initial studies and compare the results to the historical data (owned by Brunel/Exeter University). A supplier looking to bid for the work will need to have access to the reports and data in full. Interested parties must be able to deliver the full programme of works, including the project report, by the end of March 2018.
