Questions about Pure red line CRS

[lindwurmx]

Hey everybody,

I have been reading forums and i have a question about the pure red line crs's.

1) Firstly what exactly are considered pure red line? Those with red legs but with hino and mosura pattern?

2) Is it safe to say that the low grade Crs we can find at most lfs are pure red line since its said pure red line refers to shrimps that have not been crossbred with golden/white shrimps?

3) Is it possible to breed out high grade Pure Red line CRS with low grade Crs?

Sorry for my poor understanding of the topic, but i hope i get some help and a better understanding of these amazing critters.

I don't know the proper way of describing pure red line. Pure simply means, the line has not been mixed with golden genes.

Those C grades in shops may not represent it's pure red line. The weak colors may be due to poor condition, weak genes or just some culled of slightly higher grades.

Chances of producing high grade CRS is very slim, let alone high grade pure red line. However, we don't know what miracle may come out of it.

I want to know as well is the quality of pure red line is better than golden crossed with crs or just pure red line wont produce golden offspring?

if you really want pure red line.. you have to go back to the very basic.

The history of the crystal red shrimp is that... it was firstly from the bee shrimp. The original name of the crsytal red shrimp is red bee shrimp.

The crs or red bee shrimp is the mutation of the red reccesive genes in a normal bee shrimp.

To get almost pure red line shrimp, you would have to breed from normal bee shrimp. It will take years of selective breeding before you can announce that you have a pure red line.

Pure red line does not mean red legs and mosura. A random mosura bought at a shop and pure red line a grade, compared, the a grade will cost at least alot more than the random mosura.

what do you mean by the quality? are you talking about the colour intensity or the pattern?

you are right to say that pure red line will not produce golden offspring.

In a way, lets say the world only has two colour dogs. if there is a pure black dog with no white genes, mated with another pure black dog with no white genes, the offsprings of future generations will never produce any white dogs provided selective breeding has been implemented.


since golden genes is a gene, if the crs is a pure red line, and you have only bred pure red lines, you will NEVER get a golden gene unless mutation has occured which will be very very very very very rare. most likely mutations will result in instances such as producing purple shrimps.(example)

to answer your question 2: its not safe to say that all c grades are pure red line. for all you know, c grade with golden = b grade + golden + c grade. it is not possible that 100% offsprings of c + golden = B + golden. there will definately be some c grade retained.

so maybe some of the shops selling c grade might have golden genes in them.

Hope this helps.

Thx for the nice detailed info

"what do you mean by the quality? are you talking about the colour intensity or the pattern?"

I mean both colour intensity and the pattern. If pure red line has same quality in term of colour and pattern with crs crossed with golden, than I rather not buy pure red line which is more expensive coz i dont mind to have some golden offspring

[NingNing]

if thats what you mean then yes. pure red line is definately better than regular crs. the intensity of the white and red is very prominant.

even if you wanted to buy pure red line, honestly i really don't know who is willing to sell. =P.. as you can tell it takes alot of effort just to breed out one pure red line..

what NingNing has just described is the very basics of selective breeding, a methodology for eliminating a certain traits from the gene pool. technically you cannot really eliminate all traces of a gene from a population by simply line breeding. this is where genetic engineering defers from breeding, whereby genetic engineering entails going into the embryo's DNA and specifically remove or replace some gene sequences.

on a practical scale, after many selective breeding generation, one can statistically say that the occurrence of a certain trait is ALMOST zero, but still one can never state categorically that they are not there in your breeding population. PURE is simply a definition, there is nothing magical about it.

Some of the Jap breeder call Pure Red Line as Deep Red Line. Hence the CRS has very deep red. It is interesting thought to breed from low grade CRS, those are more like crystal orange shrimp with bad white, they you have to breed them to crystal red shrimp, then deep red with good white, red legs, it will take a long way.

Pure Red Line and pure red line may means 2 different things.

Ahhh.. Very very thankful to all of you peeps!!!

Kudos to all of you. Everything seems so much clearer now.

Thanks NingNing for the detailed information.

So i guess its back to basics and patience if anyone wants to be sure thay have Pure Red Line Crs's huh.

[lindwurmx]

ok. a bit off topic but I'm just being curious,

Anyone here who has breed Pure Red Line Crs?

Just wanna say CONGRATS!!!! to whoever has done it!!!

Cheers!!

It always reminds me of... Adolf Hitler and his ideology of perfect race:

A pure Aryan race, people with blue eyes, blonde hair, muscular (in the case of men) and beautiful (the case of women). He wanted all Germans to be racially pure because he wanted to start his own "super" perfect race.

So basically we are no better than Hitler anyway but no, we don't send the low grades pets to any concentration camp, we just made tons of money out of the highly sought after "high grade" specimens. And we call this an art form or passion

Hi, you are getting a bit offtopic here - we are talking about shrimp breeding which cannot be compared to mass murder...
The question is if crossing in Snow Whites to get higher pattern lowers the quality of white color and which exactly is meant if somebody talks about 'pure red line' is nothing political.
