Dyeing lakes (33 posts / 4,492 views)

So I'm on a club water currently which is mixed match and carp anglers. Big head of skimmers and an unknown quantity/size of carp. Every year they dye the lake in the run up to winter, this is because the lake was gin clear before and was hammered by bird life.

I've fished it the past couple of days and noticed since the dye went in a couple of days ago the fish have really turned off, it's not a hard water by any stretch but I've blanked 3 days in a row as have others. Any reports of dyeing lakes turning the fish off or it having negatives effects in general?

On my syndicate...we have a really bad weed issue....in previous years we have had to manually remove the weed in work parties to make some swims more fishable....we tried dye for their first time last year and it didn't really work...we tried it again this year and its kept the weed to acceptable levels...and TBH its fished its head off...i think this is the best year by far...only a few of the big guns have some out but the backup fish have been seeing the bank and ive even Managed to get a few under my belt....even had 2 in 24hrs which is quiet an achievement on the lake.....

It seems a strange time of year to put weed dye in , the experience I had with it was to start the application in it's largest doses in February so it was ready for spring growth, then smaller doses throughout the summer to keep it topped up then tailer it off in the autumn then start the process again.

This isn't anything to do with weed, it's about predatory bird life eating all the fish. Killing off the weed is just a side effect on my lake, not a welcome one.

I think the reason they put it in so late is because the attendance at the lake drops off over winter hence the previous rise in bird life. Haven't seen a cormorant on here since I joined but heard other lakes in the area have issues. It hasn't stopped Mr heron having a go though.

Good to hear it's worked wonders for your syndicate. Wonder if it's spooked the carp on mine as the lake already has its pads cut back and barely any weed. So no where for the carp to hideout other than a no fish zone.

I never saw it go in but I'd say you're probably right. Lake has a slight blue hue to it now. I've heard the dye he uses is kelp based if that helps?

The dye we have had the most success with is the green dye....I know very little about fishery management so leave this to the people whom have more knowledge.... i just do my bit at the work parties......

Have you tried other measures of keeping the predators at bay.... ive heard they need adequate space to take off and land, i.e. if the water is surrounded by trees this can put them off. Or installing floating fish refuges .....the club i am in has had an issue on one particular water when they cut all the perimeter trees back.... they put in refuges to give the fish some shelter......

As i said above i know less than nothing about fish management so i am only passing info i have gleamed from the club forum

Oh same here, I think you got the wrong end of the stick. I am in no way a fishery owner and wouldn't even know where to start haha

Removing solar energy from the lake? Sounds as stupid as putting a weir across a river.

When will people begin to deal with the root causes of the issue, rather than 'Doing a Farnham'?

Blue dye is used in my syndicate, worked to a degree last year but far better this year and agree I'm sure it knocks the fishing a bit when introduced.......

What's the root cause of excessive cormorant activity? They can't let that go on forever and just perpetually restock.

Cormorants had to adapt or die. Their food resources in their natural ranges have been depleted by humans, causing them to feed, root and nest inland instead of within coastal ranges.

It knocks the fishing? It completely destroys the ecology. What do you do when you want to remove the plants from a garden? Cover it in plastic and remove the sunlight. It takes a while but those who have done it know that nothing survives. I think even the chironomids suffer as a consequence of dye applications in lakes. .

Where do the insect eating birds (swallows, martins, hobbies...) and bats (Daubenton's etc) find their food now that the dye has killed the weed the aquatic invertebrates live on?

Yeah how does the natural food cope with the dye wont that die off with the weed.
Are you sure?

This action cannot be undone.

Yes, continue
