You are allowed to use 4 fishing rods at any one time when river fishing, but in order to do this you require 2 fishing licences, I am sure you can do just fine on 2 rods though.

When fishing by the river and there are no bins, please take your litter home, not only does it annoy other fishermen, bird watchers and other widlife lovers, to see litter lying around, but it is also one of the reasons for death to widlife, getting caught up in fishing line and plastic packaging.

Not only that it can also be a polution problem to rivers.
