2001 The Environment Agency (EA) Tamar and Lynher Rivers and Estuaries Shad surveys and records
1. Records of Shad sp. and Allis Shad catches by commercial salmon netsmen (Allis Shad where species identification confirmed from examination by expert); 2. Records of Shad and Allis Shad (Allis Shad where species identification confirmed from examination by expert) caught by rod anglers, angling clubs and commercial salmon and sea trout estuary netsmen; 3. Records of Allis Shad caught and examined at Gunnislake Fish Trap; 4. Records of Shad (presumed Allis Shad as inferred from trap records) counted by Gunnislake Fish Counter and observed on camera footage as they migrate upstream at the tidal limit; 5. Sightings of live Shad; 6. Records of dead Shad carcasses; 7. Records of Shad egg surveys. Egg surveys in estuary or river using a standard long-handled macroinvertebrate kick-sampling net and technique. The original database is held by the Environment Agency.

A Logie Aquantic Resistivity fish counter records fish migrating upstream; an individual fish can be checked by finding and examining the corresponding camera footage. EA expert reviewed all images. A fish was deemed to be shad if it was laterally very thin, displayed a weak swimming style including failed attempts to migrate upstream at the fish pass, and was observed to have a deeply forked tail. Records of shad catches from anglers/angling clubs. Fixed fish trap at Gunnislake which catches Allis Shad as they migrate upstream. Records of shad from commercial netsmen operating seine nets in the Tamar and Lynher estuaries. Egg surveys in the river and estuary using a standard macroinvertebrate kick-sampling net and technique.
