Does Salt not kill off Invertebrates like Swan Mussels, Shrimps, Leeches, Snails and Bloodworm beds etc.... ?
I know it kills off water plants like Water Lilies, in fact any that have a Rhizome.
Seems like a act of sheer stupidity to me.

I've been going back through this again, from studies on using salt to kill weeds, to road salt getting into water systems.
0.1% of salt in the water body is enough to do long term damage, reducing fertility of various water creature.
Sorry for the American spelling of litre, but this was in relation to using salt to kill weeds in the water.
A commonly cited dosage is using 1 gram of salt per liter of water, but studies have found that 860 mg (which is less than 1 gram) per liter is considered toxic and stressful to aquatic life, including fish.

Not sure if I've done this calculation correctly. But a lake measuring 100m by 100m with a depth of 3 meters is 2.5 acres in size & contains 30 million litres of water. If I times 30 million by 1 gram and convert that to kg, it equates to 30,000kg. So you would need to put 30,000kg of salt into a 2.5acre lake to make it toxic

I'm sure the sheep on some water may come close to that amount over a season
I hope there will be enough left for my fish and chips on Fridays

It's not equally dissolved across the whole lake though, that's my point. He's chucking in lumps up to about 1/2kg in size.

Do you know the force required to dissolve that size block. It'll be there a long long time. The release of sodium in to the water will be slow. It doesn't just fizz and dissolve instantly leaving a huge salt dead zone. A slow and steady release results in a constant beacon of attraction for the fish. Attracted for the additional sodium in the location to utilise it for osmoregulation.
A dead zone is more likely created using small granules en masse. It'd be worth some underwater footage of a big lump of salt and how long it takes to dissolve down to nothing. Stick a probe in the water above and test the salinity in the locality too. I'd hazard a guess that a 1kg lump lasting a good while!

Some anglers use salt and rate it but i must say myself i dont use it because its never seemed to do anything as far as catching goes.

They talked about salt on a recent Baitworks podcast, Mark had found no evidence in his tank testing that carp were remotely triggered to feed by salt. Maybe carp do seek it out to get rid of leaches etc on them from the winter, beyond that it feels like it's another good way to waste some money.
