I want to know if freshwater fish are able to utilize dissolved vitamins in the water. If so how do they do this is it by consuming water, the movement of nutrients across the gills or skin? I know there are a few aquarium vitamins supplements that recommend adding it directly into the water but I am struggling to find the mechanism in which this works. Papers that explain the uptake of dissolved vitamin by fish would be much appreciated.
Is the uptake of dissolved organic nutrients in the water only possible by marine invertebrate?
Please see below article.

There are the two groups of vitamins '' water-soluble and fat-soluble''.
Yes, fish are used
Of vitamins dissolved in water
This is recommended by fish breeders
With the addition of vitamins to additive to increase the growth of fish through the full utilization of feed------I advise you to consult the Fish Feed Research
But how do they take up these vitamins in the water? All the research I have found so far involves supplementation onto the feed. I have found some papers about thiamine bath treatment in rainbow trout, but no mention about the main pathway in which they take up these vitamins. Putter‘s theory talks about the utilization of dissolved organic matter but this is mainly by marine invertebrates.
Ozgur Yilmaz Ozgur Yilmaz Tariq Almaliky Thanks for the reply. Please see my comment above. The paper that was supplied takes about water-dissolved vitamins but this implies the addition onto feed, with leaching being a major problem. I am wondering about direct addition into the water and the Major route of take up for freshwater fish. I assume that because marine fish consume more water than freshwater fish that marine fish would have access to it via water ingestion. the Paper also mentions the take up of minerals by fish other then the feed but this is not the same for vitamins.
