I raise freshwater shrimp (Macrobrachium rosenbergii) in my small windmill pond here on my farm.
The shrimp are bred and hatched out in salt water and then introduced to fresh water for “growing out”, this is what I do.
I purchase 30 to 60 day old juveniles, stock my pond in May.
I feed a 32% protein sinking catfish feed and harvest the shrimp before cold weather sets in in the fall.
The shrimp do not survive in water temperatures under 65 degrees or in water temperatures above 95.
Any shrimp that I do not harvest will not survive the winter here…
