Smaller sized PE mysis coming spring 2010

[Delphinus]

The story I heard was PE Mysis came out of Lake Okanagan itself. It was introduced in the 60's or something and got out of hand. I believe for this reason it's also not legal to transport them live, for fear of contaminating other water sources in the event of an accident. I could be wrong on the transport part, I can't find any info on that.

I did find this:

Okanagan Lake - British Columbia

Following the "success" of the Mysis relicta introduction in Kootenay, managers decided to do the kokanee salmon in Okanagan a favor. In 1966, they introduced the opossum shrimp. The expected benefit was never realized. Kokanee salmon and native kokanee predators crashed while Mysis relicta reached such high densities that a it became the focus of a commercial fishery. Mysis.com offers packages of frozen Onkanagan Lake opossum shrimp for use as food for aquarium fish. See the Kokanee Salmon Heritage Project web site for more information on Mysis and other causes of decline in the Onkanagan kokanee population.
