People interested in high grade CR are sometimes keen to collect so called ‘red line’ shrimps. This expression refers to the fact, that some high grade CR have SSS patterns through selective breeding of low grades. Besides, it’s assumed to prove that no Snow White shrimp has been crossed in to improve patterns and grades.
In addition to the red line concept, some breeders’ names are a guarantee for high quality: Suzuki, Shirakura, Ueno, Hakata and Ebi-Ten are well known Japanese breeders who have been working for long time on shrimps. Also ASSA, a Japanese breeder association, stands for CR with deep color density. In Germany, some CR are sold under the label ‘Japannachzuchten’ (=offspring of Japanese lines) or new line names like ‘Ebi-Ishi’ – but what’s all this really worth it?
The truth is most German folks buy high grade shrimp from Asia, spawn them and sell them. Often, you even do not know if you get rejected second choice shrimps – or even some which have been crossed with unknown stock. See: the label ‘Japannachzuchten’ is nothing more than a marketing tool since you cannot prove the genetical background but only trust your reseller.
