Shelf Life 'Scare' |

Front page of this weeks Angling Times is the news item about tests done over a period of time on certain baits. The study, carried out by respected fisheries
management consultant Ash Girdler, involved groups of carp being fed an exclusive diet of a given bait over 12 weeks. The baits were peanuts, sweetcorn,
maggots, tout pellets and shelf-life boilies. Ash ensure that each group got the same calorific content (eg as maggots are around 90% water, the group of carp
being fed those received more) The growth rates of the carp, in order of most to least were, trout pellets, peanuts, maggots, sweetcorn and finally shelf-life
boilies. One of the main 'shocks' to come out of the test was that 85 of the 90 carp being fed shelf-lifes died. Not only did they show no growth but
their internal organs were 'shot to bits'. The ingredient believed to be to blame is the preservatives (benzoic acid being identified as THE lethal
one) inhibited the carp's ability to process nutrients, so they effectively starved to death as well as being poisoned at the same time. The editorial
comment in the AT did point out that we should act sensibly on these findings as the reports were carried out on baits from 8-10 years ago and that shelf-life
'technology' has moved on since then, and that fish in lakes have all manner of baits fed to them, so they can pick out a balanced diet. Interesting
study though I, sure you'll agree.

Interesting (ish) BR.
I think anything that is fed 1 exclusive thing for 12 weeks wouldn't be in too good a condition. Any comments on the fish that had just maggots or corn?

Apart from the growth rate, no.
Dunno if you saw some time ago the results of the autopsy on a carp that was fed on high oil pellets, that has certainly made me think about using them in any sort of quantity (I reckon they also fill the fish up too much, Martin Bowler reckons the pellet diet of barbel has not only helped make them bigger, but as they can rely on stores of fat, harder to catch too!)

If preservatives like benzoic acid have been proven to be harmful to carp then defra or someone should ban there use. And any caring bait company should not be
using such products in the first place.
Having said that, any research that involves a controlled diet of one type of food is always going to be flawed as no carp is going to only eat one type of food in a natural setting. Just pleased that the bait I use is 100% free of preservatives, eggs, egg products and chemical flavourings $id Watch out for drunken squirrels |

About 5 years I had a go at preserving the old K1 bait, we put the recommended dosage in the bait, it turned in 3days just the same as the unpreserved
version, then I doubled the dose and it still turned in three days, then we doubled again and it still turned at five times the level recommended for humans.
The preservative was designed for use in shell fish and the so called chemist was saying put more in its only for fish, bloody joker just wanted to sell us the
preservative for silly money. It was a bummer as that stopped the shops stocking the baits but I couldn't be responsible for poisoning untold fish up and
down the country. Another thing some well known bait firms preserve thier frozen range of baits too this is so if the freezer fails in your shop all the bait
is not lost be aware things are not always as they should be, money comes 1st for most in this game

Sodium Benzoate (E211) is the preservative it's also called benzoate of soda, has chemical formula NaC6H5CO2. It is the sodium salt of benzoic acid and
exists in this form when dissolved in water. the problem is not with the preservatives but with the amounts being used. I have seen figures quoted of 2% in the
past by people; interesting when you consider that the concentration as a preservative is limited by the FDA in the U.S. to 0.1% by weight
Most of the bait companies in the past actually used Potassium Sorbate, which is is used to inhibit molds and yeasts in many foods, such as cheese, wine, yogurt, dried meats, and baked goods. It can also be found in the ingredients list of many dried fruit products. In addition, herbal dietary supplement products generally contain potassium sorbate, which acts to prevent mold and microbes and to increase shelf life, and is used in quantities at which there are no known adverse health effects. It's not the preservatives at faults, rather people with little idea of bait making in it for a quick buck. Dunno if you saw some time ago the results of the autopsy on a carp that was fed on high oil pellets, that has certainly made me think about using them in any sort of quantityTo the best of my knowledge this has never been proven as a scientific fact and if someone can post the actual paper that this 'urban myth' sprang from, then I will admit to being wrong! |

Some very inormative points there Kev, down to everyone being sensible from the manufacturers to us users I guess.
Didn't know some of the 'big boys' added preservatives to their freezer baits, kind of makes sense but if they're having you believe their bait is free form them, then that is misleading info.on their behalf.
