Crawfish sacks weigh between 20-30 pounds. They are usually packed with about 300 crawfish (on average). But, if you order a sack of crawfish to go and it weighs less, don’t worry. You could be getting more than the normal amount. Because we use pounds as our unit of measurement for selling crawfish, we don’t always know the exact number of crawfish in each sack. So, if your sack weighs less than 30 pounds but you ordered a large one—don’t worry. You could have more craws than usual.
