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.
