Many foodservice clams are sold in a 51 ounce can. The important factor in canned clams is the drained weight. The drained weight of a 51 ounce can will vary from 22 ounces all the way down to 16 ounces. With a 6 ounce per can difference on a case containing 12 cans that would be over 4 lbs less clams. At a value of $2.50 per pound the value difference of the two cases would be $10.00. This is normally not a problem with frozen clams as they are pack as a drained weight product.
