From your description I am not sure if we are talking about the same thing. Here in Minnesota we call freshwater shrimp, Scuds. gammarus. Many different strains. Minnesota is home to several, one in particular, Gammarus lacustris. The largest of the strains. Winter is the best time to harvest them. They are harvested underneath the ice. They are in concentrated numbers under the ice in the spring, due to the abundance of algae growth on the bottom of the ice. Little is written on this strain, in such ways as, intensive culturing. They are thought to be annual breeders and cannibalistic. I also tried to breed them in a more controlled environment, with little success. This was mainly do to time restraints, devoted to my beloved waterchanges. I do raise the Hyalella Azteca with ample success, none do to my expertise:crazy: This particular strain is very easy to raise. Actually there is nothing to it. Aquarium, green water (phytoplankton), and hang on. These are very prolific and are not seasonal in propagation rulings. I do not know if you can get your hands on these in your country. I would first try to culture the ones you have. If there is no ease in multiplying them, go on to something else. Too much out there to have at our disposal, which in turn allows more time for the beloved water changes of the host that you chose for husbandry.
