any research been done on the effect of dairy orientated bolies used in quantity on small waters and their effect on oxygen levels?

In a word I'd say no. Any very large amounts of decaying bait could cause problems, as does weed growth. I'd however suggest that bait quantities would have to massive to make any noticeable effect - especially over all the 'natural' factors occuring (like the weather).

The first thing that happens to milk protein based baits that are left uneaten (as if!!!) is that they float to the surface, this usually happens after 3 or 4 days (depends on quality and %'s of milk, water temp, PH etc) these are then pretty easy for the shite hawks, coots etc to scoff.
If you see loads of baits floating on the surface, then the chances are that someone is overbaiting, but I'm uncertain of it's effect on the dissolved oxygen content.

Cheers lads, I know detrivours will eventually break these things down, but the effect of some of the preservatives I feel does cause concern? particularly over relatively short time periods

I remember netting a club lake early in the close season and we dragged in hundreds of boilies . Obviously everyone had thrown all their left over bait in and it was just lying there uneaten.

That wouldn't have been any milk based baits Steve (as per the original question) but most shelf life baits will sit on the bottom for eternity.
Get a packet of shelf lifes and drop one in a glass of water and see how long it stays whole.
Do the same thing with a food bait (e.g. A8, Solar frozens etc) and see what happens to them.

yes your quite right carp angler, we used to use the Fred Wilton stuff after it first got publicised in the orange BCSG mag (Towards the Ultinate Bait), lot of constrovasy about it at the time, I dont think the word boilie had been coined in those days, we used to call them skimmed baits, because we used to boil them in order to put a skin on them, they did break down however, but some of these shelve lifes are a whole new ball game!

Mind you I've bought PVA which appears to stay on the bottom for eternity. Since the growth of commercialism in the early eighties, carp anglers have been ripped off big time by many companies.

I dont think that preservatives would have a neggative affect on the B.O.D of a pond. There very nature is a bacterial fungicidal inhibitor. So theory would suggest that if a water was subject to too many preservatives, the B.O.D would reduce. The damage they could cause to the bottom of the food chain is another question all together.
