Salmon Parr v Trout Parr

22 September 2011
Can you tell the difference between a juvenille trout and a Salmon Parr...
Salmon parr (I) can normally be distinguished from young brown/sea trout (II) by the more streamlined shape, deeply forked tail, longer pectoral fin, lack of orange on adipose fin, smaller mouth, sharper snout, only 1-4 spots on gill cover (often one large spot), well defined parr marks.
