80 mesh = 177 micron; 100 mesh = 150 micron

Feeds sifted through a 177-micron opening (a U.S. No. 100 sieve) have  been successfully used for increasing survival and growth of minnows and catfish fry (http://www.fao.org/docrep/x5738e/x5738e0j.htm#2.%20grinding).

In contrast to the intensive poultry and livestock feed manufacturing industry, where incoming ingredient sources are seldom ground to a particle size below 1mm, the manufacture of good quality pelleted aquaculture feed necessitate that all feed ingredients be first ground so as to pass through a 0.25mm sieve (for premixes and starter crumbles) and a 0.35mm sieve (for grower and broodstock pellets) so as to meet the physical size requirement of the animal farmed and for maximum nutritional benefit to be gained from the nutrients present. (http://www.fao.org/docrep/field/003/ab467e/ab467e03.htm)

Shrimp feed raw material particle sizes are generally finer (smaller) than those required for fish due to the small size of shrimp.
