NCFE: National Centre for Fisheries Excellence, one of a number of scientific organisations researching into fishery management, now abolished
parr: next stage of development of a salmon after a fry, similar in appearance to a baby brown trout, about the size of a finger with brown markings
riffle: when the surface of the river water is slightly broken, and the current is moving faster than a glide (see above)
salmonid: migratory fish including salmon and sea trout
smolt: The juvenile salmon, at some point between sixteen months and two years after achieving parr form, starts to change physiologically. It develops salt-excreting cells, and it takes on a silvery appearance. Once fully silvered it becomes known as a smolt, a fish about six inches long. In this form it makes its way downriver to the saltwater estuary. From there, by degrees, it makes it way in the company of other smolts and salmon to the feeding grounds in the North Atlantic where it may remain from one to four years.
Spey cast: an elaborate double-looped cast much beloved by Highland gillies which has the merit that the fisherman never gets his line tangled up in the bank or the trees behind (as in an overhead cast) because the loop of the Spey cast is always in front
