Hana Yaki Nori

Cutting nori into thin strips seems to elicit a feeding response faster.

At the National Aquarium in Baltimore, we feed nori to supplement the diet of our filefish in our community tank.

So TIL filefish should be fed nori as part of their diet. Crap, I feel like a bad fish mommy. My filefish is pretty fat though so I guess that's good. Looks like I'll be popping in the seaweed clip tomorrow.

If he's fat I think he's good! Probably similar to tangs, seaweed is great and helps build up their immune system but they will do okay with a quality pellet/flake.
If you have filefish and like macroalgae I's suggest adding in some kind that wont grow like crazy. I see these guys in the wild in Florida and they seem to feel very cozy inside of macroalgae formations.
Not sure if it is truly beneficial but its an observation if mine

Tried raw nori and my fish won't touch it so I went back to roasted.

I'm sure you're a fine fish mommy

The filefish we have at the Aquarium might be a little different than the species we keep in the hobby. Ours are orange filefish and each one is probably a little over 2 feet long. Both eat the greens, but the one really seems to pick at it with vigor:





We also sometimes supplement with lettuce as well.

Even raw nori is toasted.

I disagree. There is also nori in pieces that is just dried, at least for feeding fish. Nori contains a lot of vitamin B12 which is destroyed by heating.

Look up the process. Raw nori is still toasted.

 

[Hans-Werner]

Which process please? I think the nori sheets for human consumption may be toasted. I think the Nori on the picture attached are just dried.

Are the green Nori sheets the roasted ones and the red ones the raw ones?

They are different species. Red tends to fall apart faster in water but some fish prefer the taste. Some prefer the green though.

Description of one brand of raw nori:
"Please note that this nori is not 100% raw. We thought it was because it's not toasted until someone alerted us! This nori is hot air dried at 80 degrees C and then roasted for about 7 seconds at 230 degrees C.'"

Another brand:
This nori has not been heated above 105° F during its production and is suitable for use by raw and living food eaters. It contains many minerals including Calcium, Iron, Vitamin A and C.

So though it may be brief and controlled it is part of the process.

Also, heating does not negatively impact nutritional value as much as some think. One source:
The vitamins in which some deficiencies are occasionally observed are: A, D, E, thiamine, riboflavin, niacin, folate, and B-12. Of those, only thiamine, niacin, and folate would be destroyed significantly by excessive exposure to heat and/or water.

Another affect of heating foods is the increased availability of certain phytonutrients.

I think the important thing here is when buying nori for human consumption it can be seasoned. I've stopped by a local Asian market but trying to determine if the nori was seasoned was quite difficult. I've been buying 2LF bulk nori from amazon, 100 sheets packs and is less expensive than the standard brands.

I looked for quite a while and tried to find one without even salt. This ones ingredient list has only seaweed so I bought it. I'm considering buying a baby whitecheek tang because they're one of my favorite fish and just letting him graze on it all day until he reaches 5 inches or so and then rehoming him. I know they love to swim so I don't want to keep him past that since he will only have like 7 body lengths to swim

Thats a gorgeous fish !

I put some nori in the tank yesterday but so far haven't seen him trying it out at all (but then again I'm not in front of my tank 24/7 as much as I'd like to be ). I have noticed him pecking at the rocks in the past so maybe he just needs some time to find it. I'll be keeping an eye on him!

Resurrecting.

Ive always used plain nori but bought some with sesame oil and salt.

I would assume that sesame oil may be harmful to the tangs digestive tract? Not too worried about the salt as I can presoak it in rodi.

 

[Hans-Werner]

Sesame oil is not the best oil for marine fish. It would be more favorable for freshwater fish because it lacks EPA and DHA (long-chain unsaturated fatty acids). I don´t think that the oil will harm the fish.

Thanks for chiming in. Do you think its helpful or necessary to presoak the nori, then drain the water before serving?

If I didn't, it sounds like the tangs should be ok consuming the oils..

Agreed.


That drying process for "raw" is not the same as toasting....which sounds extra contradictory thanks to that "seven seconds of toasting" that was mentioned.

But toasting as in toasted seaweed is not 7 seconds long and is done at twice the temperatures that were reported for "raw" seaweed.

Toasting as in toasted seaweed is just what you'd think – like a toaster, or toasting something in a hot oven. You're looking at around 350ºF for "a few minutes".

There's a large distinction and the "raw" proceedure is being used specifically to preserve more nutrients/enzymes whatever.

Also, "raw" ≠ fresh.

You can "thank" the food industry and "the English language" for any "confusion".

Wow. Never knew there was so much behind Nori. Good Eats episode in order.

Mcarroll - your thoughts on feeding Nori with sesame oil/salt? Should I stop being lazy and just go back and find a raw, plain, one?
