Chemical analysis shows that bloodworms contain 9.3% dry matter and of this there is 62.5% crude protein, 10.4% crude fat and 11.6% ash with 15.4% nitrogen free extract.
Yup, that confirms what i thought. The bloodworm itself is mainly water. Of the
9.3% of it that is dry matter, 62.5% of that is protein. So 62.5% of 9.3% is a total protein of around 5.8%...
So you are getting very little protein/kg of bloodworm. In contrast many manufactured feeds vary from 30-50% protein. However, this doesn't mean that bloodworm are not a good food. I find the fish really like the Hikari type which are supposed to have lots of vitamins in them. I think many of us underestimate the crucial role vitamins and other trace dietary requirements play in growth and health of our fish.
For example some dry foods that have been manufactured some time back may keep a lot of their protein content but have almost zero vitamin content. With vitamin deficiencies you may not maximise a fishes growth even with tonnes of protein intake.
(Works the same way in humans too, 4 fruit and veg anyone?)
Haha it would be interesting to see how many here pay more attention to their fishes nutrition than to their own - i would probably fall into that class lol!
