No Ian not an expert in anything, but my opinions have formed from fishing rivers for over 50 years, I have never said I was speaking from a "position of fact" or" fisheries expertise" and for you to post that rather sarcastic remark is IMO below the belt and uncalled for.
I have seen the quality of river fishing decline during my lifetime to what it is now, that is a fact, I know there are ( and I mentioned it in my post) a myriad of reasons for this, amongst them ill informed reintroductions of otter where no pre introduction survey of the ability of the environment to support them were done.do you deny that otters have damaged fish stocks.
I have never said that fish stocks have been wiped out, if you are to quote me I would ask you to have the good manners not to put words in my mouth please.
If the EA surveys are to be believed everything is rosy and our rivers are doing fine, IMO they are not doing fine they are going downhill.
I post on these threads because I find them more interesting than the what wellies type of thread, if there is a problem with me not being an expert just an angler with his own opinions posting on a forum where opinions abound please let me know and I will stop.
Graham,
I was genuinely asking, I do not know if you are a fisheries scientist, or if your info comes from one. I just think one has to be careful when posting opinion as many anglers will read such posts as fact and before you know it we have the rumour based mass hysteria we had a couple of years ago on the subject. Thankfully though, a large number of anglers have now taken on board many of the facts around these discussions and are better informed.
I think it is great that people have opinion, I think that drives research and fact finding, the only thing I will say is that before you listen totally to your own thoughts, do some real fact finding.
Here are a few starters:
Otter numbers were diminished by mans use of fertilisers in farming, those same pollutants also caused much harm to micro/macro organisms and fish stocks in our rivers. Once they were stopped the fish population recovered quickly. I actually grew up in the North West where most rivers were totally polluted and did not support any life until the mid eighties.
The recovery of otters has been an ongoing natural occurrence since the pollution was stopped, left alone it may have taken thirty years or more, however, the Otter Trust was set up by ill informed (we agree on that one) people and has speeded that process up by about 10 years. I would doubt there are any captive reared (you will notice I do not say hand reared as they were not hand reared, they were reared in captivity, with a view to protect their wild instincts) otters still surviving now. In addition to the captive reared otters, injured otters, those driven out by their parents, etc. Were re-located to help speed up the geographic spread.
As a protected species, it is now illegal to rear otters in captivity unless specifically licenced, it is also illegal to release captive bred otters into the wild. The RSPCA also issued guidance to it's officers a few years ago to kill any wounded otters reported or brought in by the public as the populations had reached saturation.
Over the same time period, we have seen lots of other threats arise, oestrogen probably being the biggest, but including cormorants, goosanders, over extraction, biblical flood events, dredging of spawning beds, etc, etc.
Regarding the EA surveys, why should they not be believed, anyone is welcome to attend when they are taking place, I have done a few times on local rivers and the results are normally eye opening. They do not prove that everything is rosy and the rivers are doing fine, in some cases they show many missing year classes from some species, they show growth in some species and reduction in others but this seems to be highly cyclical. What they do not show in many cases is a wholesale reduction in fish population (ensuring you look at a few years surveys as they are always in the same places and fish move around)
Apologies for not accurately stating your view on river populations, looking back you actually said on the brink, not wiped out.
Apologies also if this all comes across as an attack on you personally, it is not, I am merely using your posts as an opportunity to respond with some facts.
