Sea Vegetable Nori....... Can it be used for fish food?

[Jackster]

I have a bag of Nori seaweed (Porphyra tenera) normally used for sushi and I was wondering
if anyone has ever used it for fish food for Loricariidae or even Mbuna or Tropheus.
What I have lists Nori as the only ingredient (no additives) but it does say that the
product has been lightly toasted. My girlfriend bought the bag and never used it and
it's still sealed and not past the expiration date. I didn't want to throw it away if any
herbivorous species of fish could eat it safely. Anyone have experience with feeding Nori?

Thanks Silurus and I guess I should have done a forum search (I always forget).
I see someone was concerned about the iodine content of seaweed but I thought that kelp
has the high concentration of iodine? In fact, I know because I take kelp as an iodine
supplement myself for a healthy thyroid gland. Do other seaweeds contain a high concentration of iodine?

According to National University of Ireland, Galway

The food value of nori lies in its high protein content (25-35% of dry weight), vitamins and mineral salts, especially iodine. Its vitamin C content is about 1.5 times that of oranges and 75% of the protein and carbohydrates are digestible by humans, which is very high for seaweeds.

We feed nori by the pound to the tangs in this 2500 gallon reef tank.



Obviously the marine fish have more of a need for iodine, but I've never had any problem with feeding it to fw fish as long as you've got the filtration to handle the potential mess and are willing to do regular water changes. I wouldn't recommend it as a staple but it's definitely something the fish enjoy.
