In Victorian times, the quarry of a gentleman was defined as 'game' including partridge, deer, hares, and of course, salmon, seatrout and brown trout. That left the remainder of freshwater fish as unworthy of a gentleman. But these (coarse) fish are much more common and that is the meaning of 'coarse' i.e. 'common' or 'inferior'. Bear in mind that angling/fishing pressure and increasing pollution in the 19th century would have reduced the number of waters holding game fish making those that remained more desirable and exclusive.
Ledger comes from lidger which is a book that lies in one place which is what our fishing weight does. From old English licgan, to lie. It seems the leger form is because both spellings have been in common use for a long time so that no one's sure which is correct.
I am of course talking about times well before Queen Victoria. During the time of Henry VIII, perch were regarded as a real delicacy, as well they might.
