Question for Paul B-Anyone ??

[qwik]

After reading the thread about the benifits of fish roe I decided to try and find some at the local market . I was not able to find the same but was given a few blue claw crabs that were loaded with eggs/roe . I added a small amount to my tank figuring it cant hurt and my tank came alive. Every fish and critter popped out and went crazy eating . Corals also seemed happier .
My questions are,should I continue feeding,on a regular basis ?
Negative side effects,short/long term of fish ?
Does anyone know nutrient makeup of crab roe?

I know my tank liked it but just want to get a little more info before I continue ? I know I should of waited for an answer first but too late now . ;D

i would think that is a great idea unless you're the type of person who likes to eat the crab roe - then why are you wasting good food?!? lol.

Also - female blues are nasty when pregnant (or course they are nasty regardless) - I take it you killed it while alive?

I've seen them sold without the hardshell in an asian market in seattle (they also had salmon roe for sale) but I've never seen them sold (unless live) here on the east coast.

Anyways - caviar is caviar - gotta be high in protein and low in fat!

I would think the salmon roe would be better than crab roe due to the fact that salmon spawn in fresh water, producing roe with a much thicker egg sac. The fry need to live off of that egg sac while they stay in the fresh water so its got a very high concentration of proteins and omega 3's. Most, if not all, marine roe have very thin egg sacs and are very low in proteins and omega 3's. I'm guessing that crab roe would be the same.

I sat in on a couple of presentations by Randy Reed of Reef Nutrition and I'm pretty sure that's how he explained it! He'll be speaking at MACNA if anyone wants to ask him about the feeding cycle of marine life. The guy really knows his stuff.

I was able to get them at a local fish store,the guy had cleaned the crabs already and this was the left overs/scrap .

Well I don't know if it was fresh or salt, but my takeout sashimi came with fish roe the other night. And although it was tasty, I decided to save it for the reef. The fish went nuts!

My new leopard wrasse is eating great, but she started with the roe and blackworms.

Glad PaulB found us. His ideas have helped my tank for sure.

 

[Paul B]

I don't want to give you guys too many ideas all at once. I need to save some for my old age when I start pushing my RUGF on everyone. But then no tanks will ever crash and I like having the oldest tank on these forums ;D

Hey Qwik, crab roe is fine. I think fish roe would be better with more oil but I doubt it makes that much difference. Don't feed that stuff as a staple meal though. Only a few times a week if you can. The more fish oil you can get into fish, the healthier they will be.

 

[qwik]

Thanks PAul. I will give it to them as a snack once in a while . I will keep my eye out for the good roe next time I'm in NY,thanks again, Paul

PS I also read someone giving there fish the roe off the sushi. I checked for that in the store and they do sell it . It has preserves and some other additives in it that I would not feel right about adding to my system . Just a heads up!

my nephew works at wegmans and occasionally when they clean a fish or lobster and find eggs they put it aside for me. fish went nuts over the lobster eggs.

 

[steamman]

I thought it was illegal to take lobsters with eggs.

 

[Nickjr000]

You gotta love it! What other hobbie do you feed your pets CAVIAR!!! Out of all the hobbies or pet owners Reefers are the craziest. And I'm proud ;D

 

[steamman]

Taking pregnant lobsters will cause us to run out of caviar for your fish. Than what will you have for dinner ???

 

[Paul B]

It is illegal to take lobsters after they lay the eggs and they are hangong on the female but the eggs are inside the lobster before they lay them and you don't know that until you cut open the lobster. Those are fine to take.

 

[Hawkeye]

agree with paul b...

found this also:

"It's also illegal to take lobsters that have eggs under the tail or are marked with a V-notch on the right flipper, signifying that the lobster is female. If the lobster is damaged so that you can't to tell whether or not it has been V-notched, it's illegal to take the lobster. Return egg-bearing or V-notched lobsters alive to the water immediately to avoid a $50 violation fee plus $100 for each illegal lobster."

 

[njstillwell]

Thats great for lobsters but we are talking about Blue claw crabs....?

 

[Paul B]

I tried a new experiment today which did not come out exactly as planned. I am looking for a sticky food that I can feed torch corals with. I can feed the horizontal heads but the verticle ones are impossable to feed. They eat blackworms and look much better afterwards but I can only feed a few heads like that. Fish eggs are sticky but not sticky enough. I have a tube of anchovy paste that has the consistancy of toothpaste and looked promising but the torch corals do not like it. I can't blame them, it smells disquesting. It is also packed with olive oil which may be the reason they are cursing me out. I need to find some packed in fish oil if there is such a thing. The fish eat it but they make a "fish face" when they bite it.
Back to the drawing board.

 

[reeferwanabe]

So blue claw. lobster, salmon, I even gave some fluke eggs after cleaning it. sounds like any saltwater roe will work. Some has more oils than others.

 

[Paul B]

I am not sure but I would imagine fish eggs would be better only because they would eventually become fish and have exactly what a fish needs. I am sure crustacean eggs are fine also.
