Crawfish Breakdown for Meat & Fat Yields

I found some live crawfish in Abu Dhabi that said they were a product of Egypt. However, when I saw them walking around and got closer I could smell the Louisiana swamp.. Well, not really, but I knew they were Red Swamp Louisiana Crawfish, called Procambarus Clarkii !!

Then, I did a bit of research and they sure were, where at one time were considered an invasive species in Egypt... Some old Egyptian Baw many years ago bought and shipped some small ones and when they grew they were tearing his nets, so he called them cockroaches and threw them into the Nile River, where they went to town populating. What a great thing to be invading a country! Anyway, they now have a huge export crawfish business and even ship back to the USA. Go figure!

I wanted to break down the weights of crawfish meat, with fat and with claw meat and these are my results.

Average weight on 15 crawfish (After I boiled and ate 3 kg. (6.6 pounds) I got the following numbers below:

53 grams average weight of the 15 test crawfish
9.3 grams average weight of tail & fat
15.5% tail meat only average from total body weight
17.5% tail meat & fat average from total body weight
24% tail meat, fat & claw meat average from total weight
25% same as last but a large set of claws

So, to get one pound of peeled crawfish tails & fat you would need 49 individual crawfish- 454g/9.3g = 48.8 round to 49 crawfish.

Some had a lot of fat where the tail was 9 grams and it had 5 grams of fat. One crawfish with big claws had about 5 grams of claw meat.

Numbers seem correct to you crawfish experts?
