Anyone ever use this nori/algae, and can anyone read korean?

[museumguy]

Picked these up from an asian market today. Very limited english print on the packages but they all list the only ingredient as seaweed.

This one looks like algae/nori cut into thin strips like fettucine, but a darker green than normal nori.

This one looks like regular roasted nori to me. Do the sheets that you get from the pet stores come roasted?

Big, thicker and wider sheets of seaweed that look a lot less 'refined' than the others, and also a lot darker green than normal nori.

I figure it can't hurt to give the herbivores and omnivores something new to munch on, but if possible I'd like to know exactly what I'm giving them. Anyone use these or have any thoughts about them? Also if you can read Korean I'd love a translation

Thanks!

Watch that stuff.....lots of extra P04 in it....I would test it before I fed it.

there seems to be an interuption in the uncooked/unflavored Musubi nori supply Wegmans usually offers. I'm bummed. As long as it's unroasted unflavored nori it should be okay to use but some brands are much less refined than others.

Can't help with reading the package

Nori is about average in protein to phosphorous ratio as far as foods go. .Is there something special about this brand that includes extra phosphate?

I always thought that since algae uses a lot of things we dont want in our water column (hence the use of macro algae in a refugium), the breakdown of nori would release these things (PO4 being one of them) back into our tanks. Could be wrong here.

I don't think Tad has any nori break down in the big aquarium

Nori is one of the staple foods I feed regularly. Loaded with Mg.

can't read korean,but i lived there for a year. all i can say is that mexico has much higher standards for water quality and cleanliness. human waste seems to be the go to fertilizer in korea. the korean president had to make a public address for it's citizens to stop defecating in the streets during the olymipics. use it if you want, i'm just sayin...

I just hand fed my tank 2 sheets of Nori. They were gone in roughly 15 seconds. :bounce3:

I hope these other seaweeds might make for a nice addition to their diet rotation, and if they like the one that comes in thin strips I will be adding it to my DIY food recipe.

Either today or tomorrow I'll feed some to the tank and report how the fish reacted.

You do have a good point about nori (and much of the other foods we feed) being potentially high in more or less unwanted ions like PO4. Though I've never really seen any report on the potential negative effects of feeding nori, I wouldn't be surprised if there was some phosphate in it. My approach has generally been to do what is best for the animals in regard to feeding them, then work on the water quality afterwards by doing water changes, etc.

Not wrong Chris. Uneaten , it will contribute PO4, nitrogen and organic carbon too but so do all foods or they wouldn't be food.

The question really is how much valuable protein can you get into your organisms with the least amount of phosphate and waste.
Some foods contain more phosphate proportionate to protein than others. Prime reef flake for example delivers protein with only about 1/12 the amount of phosphate than silversides would add for the same amount of protein.Bones contain high amounts of phosphate ,so most whole fish foods are high PO4 contributors.Nori falls petty close to brine shrimp and mysis in terms of phosphate to protein ratio , right in the middle of the pack. These would all deliver about 25% of the phosphate silversides would for the same amount of protein.
The percieved problem with flake and nori and other foods is the amount that may not be eaten and left to rot in the tank. Pelletized food in multiple small feedings seems to have the edge for many in this regard.

May I ask where you got these numbers from Tom? Not because I don't believe you, but rather I was wondering if there were results on other commonly fed foods. Would be interesting to see the break downs on other stuff I feed.

Thanks,
Tad

Randy Farely put out a listing of ratios ,he calculated from a food study by Dr Ron Shimek in a post about a year ago.

Here is the Shimek article:

http://www.advancedaquarist.com/issues/august2003/chem.htm

Here are Randy's calculations drawn from the study in the article:

All foods contain substantial phosphate, but unless they have added phosphate (like some fresh, canned and frozen seafoods for people do), I am not certain that any particular type of food has more phosphate relative to other nutrients like protein than do other types. one thing that adds a ton of phosphate is anything that has bones in it, including whole fish.

Ron Shimek analyzes some foods here;

http://web.archive.org/web/20010720.../data/foods.asp

I've never calculated this before, but if you look at the phosphorus to protein ratio, you get:


Formula Two...........................176
Formula One.............................69
Frozen Brine Shrimp................232
Frozen Plankton/Krill...............182
Golden Pearls..........................273
Lancefish.................................244
Nori..........................................221
Plankton Gold Flakes...............169
Prime Reef.................................69
Saltwater Staple......................500
Silversides...............................952
Tahitian Blend..........................318

Fascinating stuff Tom. Anyone have a guess where cocktail shrimp would fit on that list?

 

[superkat]

excellent info!

Thanks for the reply Tad. I should add that I totally agree that herbivores and omnivores should be fed a varied diet and that would include nori IMO, just sharing what I have always wondered about the uneaten stuff people leave in their tanks.

Beat me to it. Thanks, Tom. :dance:

Probably pretty high since most fresh/frozen seafoods for human consumption have added organic phosphate added as preservatives.:fun4:

 

[tmz]

Correction , most seafoods for human consumption have INORGANIC phosphate( ie PO4 species) added as preservatives.

Beat me to it. Thanks, Tom. :dance:

:bounce3: I feed a mix of foods including a small sheet of nori, about half the size of a playing card that goes in the clips every morning. The fish come to it almost pulling it out of my hand. The next day I remove any waste in the clip. It will breakdown quickly and should not be left in the tank to rot for more than a day, in my opinion.:fish1:
