Size Sieve For Copepods. Harvesting them can be done with a gravity siphon into a sieve (41 microns is a good size to catch all stages of development). The main sizes you will need are 52 µm and 120 µm. Pour fresh saltwater on the top of the sieve to have them all fall into. 120 µm is a larger mesh size and it typically used to only collect. Clumpy phyto gets caught in the top… then adults, then. A generalized size range for marine copepods might be something. I had 4 that stacked, each getting a finer mesh (not sure on exact micron size). For example, when straining copepods, the 300 microns will be on top and 180 on the bottom. Turn the sieve upside down so that the pods are falling onto the fresh saltwater within the tupperware. For one, live copepods vary significantly in size depending upon life stage. You’ll want a couple different sieves. If you just want to harvest the adult pods and leave the babies and eggs in your culture then a 250 micron is the size your looking for. 53 µm is a finer mesh size, so less matter will go through it. For rotifers, the 300 microns will.
