    Default Re: Psychiatric drugs probably affecting fish behaviour.

    I remember a piece from some years ago mentioned further on in the article referring to the estrogenic from contraceptive pills that was causing changes to male fish, I think that this was where they were apparently changing sex.

    I thought our waters were supposed to be cleaner than ever... or do they just look cleaner?

    Either way it's a bit too late for this poor fella...

    If the fish are being effected by the contraceptive pill and by psychiatric drugs does this mean that the fish we catch are sex maniacs! Sorry I couldn't resist it.

    Does it make them easier to catch - the report said it made fish eat faster and act bolder

    What really concerns me is the introduction of Viagra into our water systems.... It definitely seems to make them 'harder' to catch....

    This I suspect will mirror the effects of Endocrine disruptors. The Pill being only one of the 250 + known substances (endocrine disruptors) that enter the rivers. Ergo rivers that run through centers of population will be where the fish will be affected most.
    And again only the effects on fish have been looked at and not the upper and lower life zooplankton and the impacts on them.

    Take all upper life, fish predators, if the same effects are mirrored in them, and there's no reason to think they are not, then the same effects as is being suggested for fish will be happening to them.
    Supercharged Predators perhaps???????

    If the same effects happen with the zooplankton, then you'd perhaps have supercharge zooplankton.
    It could then be argued little would change, other than a stepchange to superchargedness in aquatic life. Most unlikely I'll grant you, but watch the manufactures of the drugs try to advance this arguement

    It's big, big money for them so they'll kick and scream all the way to regulation on the products.

    Excellent!!

    But seriously, a significant percentage of the drug will be absorbed and metabolised by the individual who has taken it.

    It will then subsequently be massively diluted and treated by the local water company.

    I would be extremely surprised if there was sufficient to impact on a fishes cognition or evoke behavioural change.

    I'm not sure that's correct Shaun. I'm told there are some drugs which can go though a human body and are as efficacious after exiting as they were upon entry. Water company treatments I also view with suspicion - I'm sure Phil can clarify - so in summary, I wouldn't be surprised if the end result was the opposite of that which you suggest.
    So many cormorants.... so few recipes.
