Intresting post...
The problem of contacting a fisheries officer came up via one of the members here just yesterday.
The numbers Jim posted are in fact office numbers and if you phone them between 9-5 monday to friday someone will answer. The numbers are for the Sea Fishery Committee offices who are responsible for enforcing size limits.
The Northumberland sfc covers North Shields to Berwick.
The NE SFC covers South sheilds to Donna Nook ( Hull for those with no map

)
So first lets look at the NESFC. If you look at their website the contact numbers for their enforcement officers are here.
North East Sea Fisheries Committee - Current Bylaws
Choose the one covering the area you are concerned about and ring him. Give him as much detail as possible and give yourself a pat on the back.
Now lets look at the Northumbria SFC. The website is here
Northumberland Sea Fisheries Committee
The ONLY contact number is the one given earlier by Jim 01670 731399 which is the office number and manned as such. Lets hope that any offences you witness happen during office hours.
But it gets worse.
A member of this forum contacted me about what he considered to be a serious breach of the NSFC bylaws but did not know what to do about it. I rang the above number and asked for the contact number for the fisheries officer responsible for the northern region ( the area is split into three each with a seperate officer but only one patrol boat)
I was told "We cant give out numbers, but if you leave your name and number someone will ring you back". Which I did and the lady recognised me as a member of the committee and someone phone me back very quickly and they are looking into the particular issue I raised.
The point here is that both those committees are funded in the same way and that is by a levy on the local councils, which means you the council tax payers are funding it. One committee seems to be happy for the public to contact them the other would seem to be making it as difficult as possible for people to contact them.
Its encouraging that anglers are prepared to do something about people blatantly breaking size limits and to quote the fisheries officer I spoke to yesterday.
"Its nice to know that there are many sets of eyes on the beaches keeping an eye out for possible law breakers"
To which I replied:-
" A fat lot of good it does if they then can not report those sightings to the relevant people!"
An email is on its way today to the chief executive of the NSFC expressing my concerns and a link will be put in it directly to this post.
Cheers
