Yes that is a good question! Does the book mention a way to come in contact with the author? I wouldn't doubt that he knows the answer.

Yeah I was thinking they had to use nets. Those nets must be really fine though so that shrimplets and adult shrimp aren't sucked up.

Aren't blue shrimps blue in color once they're born or when they're grown-ups?

By the way, the Taiwan writer says that the cherries are given special food to enhance their red color. Besides, a photo in the book shows that the cherries are selected by workers before they enter the marekt. Dozens of cherries are in a white bowl each time, then a worker uses a white spoon to select the shrimps one by one or two by two each time. Those who are not "red" enough won't be selected.

Besides, the shrimps won't be drained away through the holes because there are nets

One more point:

The article doesn't mention how to contact the author. I only have the ISSN number of this book and the email address of the publisher. I only know what ISBN number is, don't know if ISSN number means the same thing. Anyway, here it is:

If you read the Shrimp Varieties page and read other topics you would see that as of yet there are not true blue shrimp strains. The "blue" shrimp are dyed blue or given special foods that make them blue but the color is not carried on to the offspring.

Does the book say what brand of food the RCS are fed?

Strange, I thought that there were blue tigre shrimp and that they is a new blue colour morf comming from the wild snow ball...

Yes, there are blue tiger shrimp. This is the first time I have heard about the blue wild snowball shrimp.

Do these shrimp breed true? That is, are their offspring blue also or is this another case of dyed shrimp?

Thanks TKD Don't those pictures of the shrimp look great. It almost makes me want to set up a couple more tanks

Guys...there are still *NO* true breeding blue shrimp out there..period. I wish there were. Most blue tiger shrimp that you see around are just like the blue Neocaridina sp...their offspring aren't blue at all. There is a tiger shrimp variety with golden eyes that, according to some people, does produce a certain percentage of blue offspring, but, once again, most of the offspring are not blue.

As for the "blue" snowball shrimp...I have them right here and I can tell you that I personally would not call them blue. They have some very tiny amount of "steel blue" on their bodies, but they look more grey than blue to me. They look a lot bluer in pictures than in real life, especially on a dark background. I still find them attractive, I just would not call them blue. Nowadays, all kinds of animals are called colors that they really don't have in my opinion (see "blue" Cambarellus shufeldtii), but calling them blue won't make them blue.

So, once again, there is still NO true-breeding blue shrimp in the hobby. If I ever come across a true-breeding blue shrimp species, you'll be the first one to know.

Ok..now let's let this blue shrimp myth die before it spreads again...it seems to perk up once in a while because people just forget the facts and get lost in wishful thinking and imagination.

Both my vampires are blue...

What's your point? Those shrimp can have all kinds of colors. Try re-reading what I wrote above. I'm talking about true-breeding blue shrimp. Have you bred your "vampires" to see if they produce ALL blue offspring or even a majority blue? No, you didn't. Hence, I don't see a point in further discussing this.

Shortly I will post some pictures in the crayfish forum that even you will admit are blue Cambarellus shufeldtii. They are not the Electric blue, but they sure as heck are not grey. I agree with you on what is currently being sold as blue is a bunch of hype, but I can tell you that I have a group of animals now that everyone who sees it say- "hey- that crayfish is Blue!". In this case though, the color is not genetically influenced, but is food based. Feed them one thing and they go greenish-brown. Feed them another and they turn blue. They can change colors in a day.

Looking forward to the pictures. But, if the color is food based then they are obviously not the type of blue we want in the hobby, i.e. a genetic color morph. I'm personally not a big fan of changing color in aquatic animals through food. There is a "yellow" crayfish in Japan (Probably a white Procambarus clarkii) that only stays yellow as long as you feed it the "special" food that the crayfish comes with. To each his/her own, though. I just don't think that food based color changes help the hobby one bit. Part of the fun of breeding various color morphs is the challenge of selecting for certain genetic traits after all.

I am pretty certain that a true breeding blue shrimp veriety/species will appear one day or another, there just isn't one in existence right now.

I will be waiting and hopefully it will be sooner than later.

badflash, I have seen pictures of your blue crays and they do look very nice

So far it looks like nothing "special" about the food. When they eat primarily plant based food they are blue, animal based food they are greenish/brownish.

But, if the color is food based then they are obviously not the type of blue we want in the hobby

You got a mouse in your pocket? Who is "we"? I want a blue shrimp and a blue cray. I don't care what causes it as long as it doesn't hurt the animals and I know what causes it. If sinking goldfish granules and spirulina flake make them blue, I think that is just fine. There is a genetic component to it as most crays eating the same food don't turn blue, and you can selectively breed for it.

What I don''t think is fine is blue shrimp that don't breed blue and no one will say how they did it.

Color enhancing food is standard in tropical fish. I see it as no different than giving your dog something to make his coat nice & shiney.
