few comments on Petes "same old" thread have inspired me to provide an informative and factual education in bait ingredients and additives for those that wish to have a better grasp of the fundamentals.....i will start a NEW thread with this link although i have just posted this on petes topic.....lets start with this and work towards a better understanding....Enjoy!

http://www.thefishsite.com/articles/200/the-benefits-of-fish-meal-in-aquaculture-diets

For those that would be interested in just what a carps dietry requirements are take a little read of this http://pubs.ext.vt.edu/420/420-256/420-256.html

Although basic and quite non specific in terms of magic ingredients and being more related to commercial feeds,it is never the less educational!

And just out of interest,is there anything specificly anyone would like information on?Answers on a postcard please folkes Or just post here!

Having lived through the era of the fish oil induced slicks

If a lipid/fat source is required to spare protein do we need to add any additional oils sources to a bait as many of the ingredients within a correctly put together base mix will already have a % of inherent sources
For example wheat germ, soya, fish meal all have inherent sources while some of the milk replacers have vegetable oils added to their makeup.
Also if an antioxidant is added to fish meal to prevent oxidization what is the shelf life for a bag of provimi for example as it comes with a manufactured date , not a use by date.

The Thiaminases issue regarding vit B1, would this extend to tuna in spod mixes

I find the glugging of baits in oil or dips based on a fish oil confusing as I’m not even sure they can detect them due to they are Water-insoluble substances &, are rarely dispersed as single molecules in the water or as the article says the they float to the top, also do Carp even have the receptor sites to detect oils?

I get this feeling at best they might act as a masking substance by limiting contact of substances with the taste receptors but also in doing this are they also limiting the contact of more important substances. A kind of tasteless energy source

Just a few to keep you going, I bet you’re so glad you asked

I wish i had never asked

Ok,in answer to your first question,NO.....Any decent basemix will provide ample amounts of lipids if constructed correctly.Fishmeal,milk replacers such as gold top and lamlac provide abundant sources,as well as certain milk powders.There are oils that play an important role in providing certain missing nutrients and those that are purely there for the sole purpose of ease of rolling yet provide very little in beneficial nutrients to the fish.Certain nut oils are also highly nutrient dense.As for do they attract or are they attractive then i would again say NO!Assuming we are talking about bulk oils.Essential oils play more of a role in taste rather than smell as we perceive it.Our smell is a carps taste.

What people must understand is that oil and water do not mix and its all down to pure chemistry.....Water is the best of all solvents purely because of its polarity.Simply put,water is a polar molecule meaning one end is positively charged,the other being negatively charged and is made up of 2 hydrogen atoms and one oxygen.Only similar polar molecules such as sugar and salt will readily disolve in water along with other soluble food stuffs.Im trying to keep this simple folkes :)Due to the larger size of oil molecules and larger surface area and also the fact that they are not electrically charged,they simply clump together and will not mix with water.Which,in turn makes a complete mockery of those that say they have winterised oils achieved by the use of emulsifiers.The shelflife of any given ingredient or foodstuff is purely to safeguard the makers if it went to court and is there as an unwritten insurance policy,so unfortunately im unable to answer that question but i will be glad to look into that one for you!
