An interesting subject this, we as humans (to use a crude similae) are notorious for binging on junk food and generally eating unhealthily, with many of our foodstuffs containing the very preservatives mentioned in that article. Yet does it constitute to any number of deaths per year homo sapien wise? (hard to ascertain what with heart disease etc but you get my drift I hope)
I know our dietry requirements/system differs greatly, would the fish 'know' when enough is enough after eating a fair proportion of shelfies or are they simply too basic a creature to comprehend that what they devour is dangerous in quantity?
I was always under the impression that carp on a big feed would quickly pass through their system any edible matter and therefore not absorb a massive amount of contained substance? Having used Pott Sorb as a preservative in my baits moons ago, I know only a small quantity is required to do the job and personally do not see it as a potential danger. However that is just my gut instinct.
As stated,these fish were subjected to a concentrated amount of preserved feed, in the wild its a completely differing matter. And surely if it was that serious as described in the article we would be witnessing high mortality rates on waters which see a lot of the type of angler who favours shelf life baits? The fish in my tank regularly get a treat in the way of a ready made crumbed up, its certainly done them no harm.
Sure would be interesting to see some of the bait companies standing up for themselves and hear their views, at the minute the silence is deafening unless I've missed some feedback?
