About this consultation
We are consulting on coarse fishing close season on English rivers.
The close season prohibits fishing with rod and line for coarse fish between 15 March and 15 June on rivers in England. There is no close season on most canals and most stillwaters (some protected stillwaters and some protected or navigable canals retain a close season, with the same dates).
We want to better understand the risks and benefits associated with any change and the potential impacts on fish populations, angling and wildlife. We want to hear from all those interested in coarse fish and fisheries, including the businesses that depend on angling, to help us decide whether we need to retain, change or remove the current close season.
We may, as a result of this consultation, make new byelaws. If we do, we must advertise them to allow anyone the opportunity to object. This will most likely happen later this year.
Why oh why are they asking this question now? It's because their revenue is in serious decline! Look at rod licence revenue. It's got nothing to do with the welfare of our rivers or the well being of the fish that swim and live in them has it? It's about bolstering the cause so coarse anglers get a better deal and thus pump money in to the system to keep jobs alive in the EA.
So where the hell are these jokers on this matter: https://www.anglingtrust.net/
