Well, with fish, a lot of fish need specific conditions to breed that trigger their breeding season, cold water, lots of water param shifts, darkness, parents have to removed as soon as eggs are laid, they need caves to rear the young, etc.
Easy fish like livebearer guppies or platys, you should always a tank full and if you have a dozen guppies and don't have a 100 in a few months, I would think something is wrong, and I look at shrimp at more in this range of breeders than difficult to spawn fish.
Shrimp kept in stable, proper water should be breeding almost constantly. Too hot, too cold, shifting params from too many water changes, improper water, too much CO2, ferts, messing with the water too much, not a balanced diet, etc are going to effect this.
Happy shrimp in proper water should be breeding, it's their genetically programmed destiny to do it over and over, almost back to back for the duration of their lives. If they aren't, they probably aren't that happy. Again, back to the guppy or platy thing. If you can't get them to breed, you are doing something wrong.
My opinion anyways. If you have lots of shrimp and no babies at for months and months, I would say they are not that happy or their water is not ideal.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
