What is my preference in terms look for PRL?
- This is my own guidance for selecting , so the below will be the ones that i will not consider as my stock shrimp for that particular line.
for example if i am going to keep 2 or 3 distinct line of PRL these are my criteria:
- The red head should cover all the way to the start of the body, my preference to provide a stronger Red : White Ratio. The main reason for PRL is that the red has to be of certain % if not the white will cover most part which is moving towards the flowerhead pattern.
- There are only a few areas that can be red such as the head, legs, body markings, tail marking, feelers, etc. Swimmerets are a bonus to give that additional red to the overall shrimp.
- I also like the flowerhead pattern and will talk about this in the next post.
Another shot of another PRL in the main breeding tank where the red ends at the start of the body. 
That is my first criteria for that tank of PRL, if it doesn’t meet the criteria, it will be transferred to another tank.
2nd Criteria onward:
- Head to body ratio, is it appropriate at 30:70?
- No deform growth, head carapace to be flush with body
- no skirting
- Legs coloured: red is the best at least for me, followed by red and white then white and red. (personal preference)
The bottom pic shows that the maru spot is missing or is converging with the white, I will transfer this out to other tanks.
There are quite a lot to transfer around and usually for this particular line i’ll start to notice the very good ones start off with already good colouration around 0.8cm. I got this line from Hwa Taiwan and he has named it M Series PRL. Those in the know knows that Hwa PRL are world class and the M series PRL is in a class of it’s own.
Continuation of selection process will begin at F1 where the F1 females will be then cross back to the F0 male. This will result in BC1 (backcross 1) and then continue to do the selection process. After a couple of generation, i’ll then back cross again to maintain the genetics of the F0 male as long as possible. BC1 is the nearest in terms of genetic as F0.
