Suspect many of you have been watching Blue Planet 2 on BBC  One.

What struck me amongst almost all the egg/sperm laying species in the ocean there is no such thing as genetic integrity.

In fact it seems the opposite.  Last night amongst other things it was an Octopus who crept in to fertilise the mate of a bigger one.  Attenborough said this was a way of maintaining the maximum genetic DIVERSITY  Strange when, conveniently for their own ends, our 'scientists' pursue the creed that genetic integrity is of paramount importance above all else..

It does seem that in stocking the Tyne, peter gray introduced fish / eggs etc from several different rivers and achieved what was probably the most successful stocking programme ever. I agree it seems that Diversity is the key.

It has happened on the Wye,  Rhine fish amongst others, You could tell when you caught a Rhine offspring by its arched back.

So Genetic Integrity is considered a favourable thing regarding salmon and Genetic Diversity is considered good for sea-species. Who decided this and on what basis? Has anyone asked Peter Gough? This is a serious question. I would like to know the rationale

What is fantastic with salmon is that there is always something you can support even if you have very diverse thinking compared to everyone else. Of course genetic diversity in wild fish is brought by the fish straying from other rivers, which may be as high as 15% of the total run. Genetic integrity is necessary to maintain specific adaptations for specific breeding habitat and is a favourite with the 'conservationists' who want genetic integrity for the stated reasons but don't mind opening up tributaries for spawning and turn a blind eye to the fact that they are not adapted to breed there neither are their offspring .....

Its weird how it works on the Tyne and this its worth continuing with it? Despite the EA trying to claim that it didn't work?

Its all very strange.
