[93] The freshwater fishes named in the next three paragraphs are so well known as to require few remarks. The Bream in our rivers and broads are very numerous and reach a large size, but of their esculent qualities I have had no personal experience; not so, however, with the Perch, which quite deserve Browne's high encomium. It is well known here that this fish shows no aversion of a certain admixture of salt and fresh water, and Mr. Lubbock ("Fauna of Norfolk") says, "the point in Norfolk rivers where the largest are taken with most certainty is where water begins to turn brackish from the influence of the ocean;" in autumn the very finest are taken by angling with a shrimp, a favourite bait in the lower parts of the Yare and Waveney. In such localities a small shrimp (_Hippolyte varians_, Leach) abounds, and it is to this favourite food that Mr. Lubbock attributes the excellence of these Perch. Roud is the local name of the Rudd (_Leuciscus erythropthalmus_). The River Nar is still perhaps the best Trout stream in the county, and the Crawfish is found in most of the rivers but not abundantly. The Trutta or trout the Gammarus or crawfish [no _crossed out_] butt scarce in our riuers butt frequently taken in the Bure or north riuer & in the seuerall branches therof. & very remarkable large crawfishes to bee found in the riuer wch runnes by castleaker & nerford. The Aspredo perca minor[94] and probably the cernua of Cardan co[=m]only called a Ruffe in great plentie in norwich Riuers & euen in ye streame of the citty. which though camden appropriates vnto this citty yet they are also found in the riuers of oxforde [&] Cambridge. [94] Merrett calls the Ruff _Cernua fluviatilis_, and mentions its abundance in the River Yare at Norwich, which he (no doubt inadvertently) assigns to the County of "Essex"; from this locality Caius obtained the specimen, a drawing of which he sent to Gesner under the name of _Aspredo_. Camden assigns this fish also to Norwich, and Spencer, in his "Marriage of the Thames and Medway," writes of the Ruff:-- "Next cometh Yar, soft washing Norwich walls, And with him bringeth to their festival Fish whose like none else can show, The which men Ruffins call." This county seems to have been assigned an exclusive proprietorship in the Ruff, to which, as Browne rightly points out, it had no just claim. Lampetra Lampries great & small[95] found plentifully in norwich riuer & euen in the Citty about may [some _crossed out_] whereof some are very large & well cooked are counted a dayntie bitt collard up butt especially in pyes. [95] Both the Sea Lamprey (_Petromyzon marinus_) and the Lampern (_P. fluviatilis_) are found in the Norfolk rivers.
