I've recently started fishing a place that has quite a bit of weed (Canadian some it) and no airer. I was told it's because the owner would prefer having the lake full of weed for oxygen rather than installing or using an airer system. And another good quality lake I fish has an airer.
Clearly personal preference, what's your views on this and why is one better than the other? And which is a better solution? Anyone know the science behind these too?

Natural lake with lots of weed will produce a natural food source.

I have never fished a lake with an airer......but then I've never fished an overstocked noddy pond that needed one

In the weather we've been having, lakes full of weed will be super saturated (over 100%) during the days. When the sun goes down, the weed that had been photosynthesising then uses the oxygen that it has generated, leaving the oxygen levels at their lowest at first light. Google the diurnal rhythm.
Unless you've got too high a biomass or there are crashes due to weather, you should never need aeration.

Two lakes I've fished, both old, silty and susceptible to blue/green algal blooms have had them 'just in case', but they're usually on through the summer. The more prolific of the two had 3 carp per acre so a proper noddy water
Both lakes were heavily abstracted in the summer too, so it's easy to see how things go out of balance quickly (note the thunderstorms thread)

Not a great fan of tinkering with nature and I think lakes should be left for nature to take its natural course. That being said owning a commercial fishery is big business nowadays and I can understand owners wanting to protect their stock. Which is exactly the reason why I try to avoid these sort of lakes as generally they are overstocked , overfished hell holes.

Okay, so let me be clear that the lake I mentioned in my first post that does have an airer is absolutely not over stocked which is why I've started this thread based on a comparison of two carp specimen lakes. I can tell you now that the one with the airer hasn't been fishing any better or worse than the one without.

Depends what your view of overstocked is I guess.

Though it should rarely be needed, it's good practice for fisheries to have something available imo, just in case.
It can happen anywhere. Look at the Mere and Big S... FAR from overstocked puddles, wiped out overnight. Nature doesn't discriminate.

Fair point but there's a world of difference between having emergency equipment available for lakes such as the ones you mentioned and the Nod waters which have them running round the clock.

Tinkering with Nature? Not really doing much tinkering saving your stock so you can still call your lake a fishery not a building site

What do the numbers really matter to You? I thought a otter fence would be tinkering with Nature would it not? It's all normal for carp to be killed is it not? Its Not like people own these fish

So was Whitwells over stocked when it had its fish kills Mike?
Was it wrong to get emergency aeration in and try to save the remaining stock?
Did the installation of an aeration system suddenly make it less of a water?

I'd hardly call "my" lake an overstocked "noddy pond" but an aeration system was installed a couple of years ago after an oxygen crash killed a few fish, including one of the named ones.
A sad day indeed.
I helped install it, bloody hard work.
The lake is all the better for it.

Be careful you don't tempt fate. No type of water is immune to oxygen issues.
