Start Off in a Pure Way 

To start off your Pure Red Line (纯系) breeding program without golden (white shrimp) recessive genes, the best way to send them for DNA test. But.... thats the practical, here, is another method that can be carried out to validate your Pure Red Line breeding stock carries golden genes. Golden CRS offshrings can appear after many generation of breeding if the inital breeding stock is not tested even without intensional introduction of golden genes.

Golden genes in Pure Red Line is deemed undesirable by majorities in communities around the world. 

The method as follow: 
- Pair A: PRL female with a golden male
- Pair B: PRL male with a golden female

If Pair A has no golden offsprings but all red offsprings, then the female in Pair A does not has golden genes.
If Pair B has no golden offsprings but all red offsprings, then the  male in Pair B does not has golden genes.

After you have comfirm both PRL of different sex has no golden genes, put these 2 together to breed, the offsprings are comfirmed not to carry golden genes, so will be the offsprings' offspring.

The chances of these 2 to breed out golden offsprings, the chance of it will be extremely remote, just like striking a $10mil lottery, but this time, the breeder get no prize.

TDS meter or Conductivity Meter?

TDS meter or Conductivity Meter? 

Often one can hear that his TDS meters are not measuring correct. One reason is it need recalibration, one will need calibraion solution to do this. Another reason is, basically TDS meters from different manufacturers are calibrated with different conversion factor.

TDS meter base on reading the conductivity of the water and convert it to TDS with a known conversion factor, it is known to be a conductivity meter of 200uS has a TDS value of 100ppm of NaCl. So very simple for manufacturers, they just get the meter to show the conductivity meter value by half and now become a  TDS meter. But some manfacturers use CaCO3 solution to calibrate and this will result in for the same water, the TDS values are different.

To avoid all the confusion, one can simply use a conductivity meters, and most TDS meter comes with conductivity measuring function.

See these golden crs or snow white shrimps with blue tint on rostrum? Golden CRS with such trait has the king kong genes. Cross this shrimps with a king kong and you will get some king kong babies.

Mosura King Kong Shrimp

mosura king king shrimpWhat can a king kong shrimp be when it gets all black? That all be the end of the trend, the new trend will be reversed, a mosura pattern like this will lead the trend.

Blue RiliThis is the first Blue Rili for Mr Wang. What is exciting is, it has a blue painted tail, unlike other type of blue, which will fade, change or disappear when the shrimp change enviroment. However, painted color does not change.

In the conversation with Mr Wang in the afternoon, he said that the shrimplets are due in no time, I will get update from him on how many pieces resemable the mother he can find. I will update in here.
