Under the legislation set out in Council Directive
1991/67/EC which was in place during the period studied
in this paper, all movements of fish between registered fish
farms had to be recorded. Additionally, any movement of
fish to a fishery required consent from the EA in accordance
with Section 30 of the English and Welsh Salmon and Freshwater
Fisheries Act (1975). Though there was no obligation
for fisheries to register with a Competent Authority at this
time, where a fishery had supplied or received fish, details
of the site, species and number of fish moved was recorded.
Dealers of fish had no obligation to register with a Competent
Authority; however, any fish movements made by
a dealer to or from a fishery required consent. Records of
movements of fish between wholesalers and retailers were
not required, nor was there a requirement for such sites
to register with a Competent Authority, however, a record
of a site would have been generated if it had received an
import of fish or supplied another farm or fishery.
