the salmon is a hardy fish i recon if it is left to its own devices it will manage easy to spawn in the reds . ive seen this lots up the south tyne and wear also loch shin tribbs . the keilder hatch is wonderfull for the tyne but dont forget the south tyne salmon for many many years they have managed to egsist. even this summer the south had a cracking salmon run even with the total counts down , give the salmon some credit they are as hard as nails their only big threats are nets . seals .and low water in hot weather on the tyne . these are the only things that i recon will be a threat to the silver leaper . the rest out at sea we will never find out thats nature i hope so anyway . i know for a fact poaching [nets] on the lower tidal stretches is being wiped out slowly thats a help well done [ea] . its a big if but if we find out whats going on out in the atlantic with the salmon maybe the numbers will improve again. but i repeat myself again the salmon is a good spawner its just getting them into the rivers from far n wide they will do the rest .
