Exeter canal(basin) worth a go some good carp in there also Big tench and Roach. Best bet is to go into Exeter angling centre and they will put you on some good venues.
If you've got tackle suitable for tench, give the mullet a go. Fight much better than tench, no day ticket to pay, and if you're really hungry, you can eat them.
yep i would go for the mullet by the sea. look for the areas of flat rock or in a harbour style situation becase the mullt like the warmer clearer water. try bread on a massive waggler or a carp baggin waggler style you will have lots of fun!
Rob try the tidal Exe, wag/stick and mag for a variety of species from dace to sea trout to mullet to grayling. Find the double locks pub and try the fields behind it.
