Chaeto question - edible for humans?

[jsker]

Many chaeto species are eaten by people, but I would strongly recommend against eating anything from an aquarium due to potential for microbial and toxin (e.g., heavy metal as well as organic) contamination:

I agree with @Randy Holmes-Farley, I would not have any out of our systems. Copper alone is toxic.

Great comments!

I agree, you have no idea what our supplements contain and I didn’t even think about toxins from our corals.

its a bit sad that we keep our fish in an environment we think is too toxic to eat out of...

Kinda goes both ways? I drink zephyrhills water but I wouldn't use it for saltwater? What toxic to us doesn't make it toxic to them? I wouldn't eat anything out of the tank period, I don't see how it's sad.

wouldn't eat anything from the tank either, but the tiger perch might end up as food if it grows too big. Deep fried, covered with garlic oil, a few drop of sesame oil, deep fried ginger slices and a few table spoon of sweet soy ketchup seems promising.

Members of the animal kingdom can handle certain toxins better than humans and vice versa. You’re taking a chance on your life. All it takes is the an allergic reaction and you’re taking a dirt nap.

Well having just done some (very small scale) testing of caulerpa and gracilaria consumption I have say..... garshdarnit, why didn't I read this before!

Seriously, thanks @Randy Holmes-Farley and this is a very important thought. I presume the problems are

a) we don't know what the supplements the companies put into their salt/trace elements

b) we tend to have relatively high bioloads leading to a much higher level of different microbes?


Fair enough. Few questions just for my understanding then, to either Randy or anyone else with scientific/aquaculture backgrounds (to include @Subsea @AquaBiomics and plenty of other people I can't remember OTMH - as one can clearly see from this post my knowledge of this is 0):

1. if we used only natural seawater from a good source, I assume we would lose the toxin contamination problem? For that matter, I'd imagine that some of the big salt companes (e.g. IO) is used rather heavily in inland marine aquaculture (assuming aquaculturing any marine fish in condition where you don't use NSW is financially viable)

2. I believe algae aquaculture (kelp, nori, wakame,etc.) are pretty intensely cultivated? How is microbial contamination avoided in such situations? Are they cultivated in fairly clean areas without a lot of runoff or large fish populations? And as an aside, if you had a dense salmon farm producing all kinds of wastes, then it would not be recommended to feed a wakame seaweed far based off of the salmon's waste?

I have a vegan daughter... you can see where this is heading!
She's an adult - I'm not that cruel, I'd tell her where it's from. After?

I just took out 1/4 from the sump as it was getting full. Was giving it a rinse so it won't stink in the kitchen trash, and boy this looks tasty.

Make sure you get all the meat out (COPEPODS)

Chaeto is awesome. Ball it up, but if you put a bristle worm in the middle it really brings it home.
