Hi Simon,
Mesh Size is, and always has been, a "Bone of Contention", and the problem is, if minimum mesh sizing is introduced ,how is it to be policed.
Successive governments don't seem to know or are at least lacking in interest.
Oh sure, they sometimes make the right noises, but nothing is being done to ensure that the immature fish have a chance to get through the mesh size and therefore get to achieve a sustainable size.
Quotas get introduced, but how often do we see trawlers coming close in and going way up our rivers and estuaries?
The commercial fisherman has a living to make, but if greed is left to prevail over common sense then the seas will indeed become barren!
Those of us still crazy enough to fish the Essex and Kent shorelines are already seeing the severe decline of our fishing, whilst charter boat prices remain high, and the catch rate is declining.
