Hi Rose sorry not to have been around as weve been busy with the pond these last few days complicated by some sort of vomiting bug I've picked up I havent felt like being around because it floored me.
Your problem is columnaris disease with the high temperatures weve all been having it will result in rapid fish loss .
Flavobacterium Columnaris to give it its propper name will attack the skin in any areas of weakness in its early stages this type of infection can be identified by small white or yellow areas on your fish .
This as it worsens gives your fish the white hazy look you can see caused by exessive mucus production in its advanced stages areas of red appear on your fish if not treated then your fish as you have found will become listless and more than probably if treated will die because youv'e left things too late I'm sorry to say .
Low disolved oxygen levels , high ammonia and over stocking of the pond will make an attack of columnaris most likely .
Good husbandry of your pond (which your not doing) reading your original post and regular system maintenance and regular water changes (something we practice on a weekly basis) all will go towards to helping you in preventing an attack of this bacteria.
you need to take a swab and take it to the vet to have this bacteria identified and I suggest antibiotic feed along with a good strong bacteriacide however because you put salt in the water do not use Acriflavin
I only hope its not too late for any remaining fish you may have in the pond
