Monitoring of Allis Shad and Smelt in Tamar Estuaries

Defra procuring on behalf of Natural England.

Background to project: Allis shad (Alosa alosa) is a designated feature of the Plymouth Sound and Estuaries Special Area of Conservation (SAC).

Cucumber smelt (Osmerus eperlanus) is a designated feature of the Tamar Estuary Sites Marine Conservation Zone (MCZ) which overlaps with the SAC.

Both species are poorly researched within the site and as a result Natural England wishes to commission research into their condition and distribution.

Requirement: Natural England requires contractors to design and undertake surveys to meet the following three areas of interest :

1. Monitoring of Allis shad within Plymouth Sound and

Estuaries SAC.

2. Monitoring of smelt within Tamar Estuary Sites MCZ.
3. Survey/review of seasonal distribution of smelt and Allis .

shad within Plymouth Marine Protected Areas.
